If a 12-inch pizza barely fits on your rack or a whole chicken has to be dismembered to cook, your toaster oven is too small. An extra large model changes that — it is a true second oven that bakes a sheet cake, roasts a turkey, or air-fries enough wings for a crowd. This guide compares the biggest-capacity countertop ovens available, so you can pick the one that actually replaces your full-size oven for everyday meals.
I’m Mohammad Maruf — the founder and writer behind WellFizz. This guide is built by comparing the manufacturers’ published specifications and the patterns across verified customer reviews, so you get each pick’s real strengths and trade-offs instead of marketing spin.
Find the countertop model with room for a 12-pound turkey, 20 cookies, or a full sheet pan. Our picks for the best extra large toaster oven are ranked by capacity, cooking power, and owner satisfaction.
Our Picks at a Glance
How To Choose The Best Extra Large Toaster Oven
An extra large toaster oven is a real kitchen workhorse, but only if you match its specs to what you actually cook. Before you buy, think about the biggest dish you regularly make — a turkey, a sheet cake, or a full pizza — then check that this oven’s interior can hold it. This section explains the numbers that matter most so you don’t end up with a beautiful oven that still can’t fit your lasagna pan.
Capacity: The Number That Decides Everything
Capacity is measured in liters, quarts, or cubic feet, and it tells you how much food fits inside. For an “extra large” oven, look for at least 25 liters or 0.9 cubic feet. That translates to fitting a 12-inch pizza, a whole chicken, or a 9×13-inch baking pan. The largest models here reach 42 liters, which easily holds two large pizzas or a full-size roasting bird. If you regularly cook for a family of four or more, do not settle for anything smaller than 28 liters — you will hit the ceiling fast.
Wattage and Convection: How Fast and Even It Cooks
Wattage is the oven’s power — more watts mean faster preheating and better browning. Serious models run from 1500W to 1800W. A convection fan is just as important; it circulates hot air so food cooks evenly on all sides, eliminating cold spots. Many ovens pair convection with an air fry function, which uses the same fan to make crispy food with minimal oil. If you want one appliance that replaces both your toaster oven and your air fryer, convection is non-negotiable.

In-Depth Reviews
1. KitchenAid Dual Convection Countertop Oven – KCO255
Our pick — over 4.5★ from 900+ verified ratings; the strongest balance of quality and price.
The KitchenAid that bakes like a full-size oven, with a temperature probe that nails perfect roasts every time.
This is the crowd favorite — 4.6 stars across 900+ owners — and the reason is clear: it truly cooks like a second oven. The dual convection system moves hot air from two fans, so your sheet cake bakes evenly and a 3-pound chicken cooks up to 20% faster than the standard bake setting. Buyers report it “Preheats in 2 min, bakes/toasts like a big oven, easy to clean, attractive.”
The built-in temperature probe is the standout feature. You insert it into a roast, set your target doneness, and the oven alerts you when it hits the mark — no more cutting into meat to check. The 28.6-liter cavity fits two whole chickens or the included 9×13-inch baking pan, and 12 preset functions cover everything from cookies to dough proofing.
Owners praise the non-stick interior and removable drip tray for fast cleanup, plus the interior light that lets you peek without opening the door. The honest trade-off: the rear heating elements can brown food faster in the back, so reviews suggest rotating your dish halfway through. It’s also heavier than most at 20.3 pounds, so give it a permanent spot on your counter.
What wins people over
- Dual convection cooks evenly and fast
- Built-in temperature probe for perfect roasts
- 28.6 liters fits 2 whole chickens
- 12 preset functions including proofing
What to watch
- Rear elements can brown food faster — rotate midway
- 20.3 lbs is heavy to move around
Ideal for: anyone who bakes regularly and wants an oven that acts like the real deal, not a toy.
Think twice if: you need a lightweight oven you can stash in a cupboard between uses — this one earns its countertop footprint.
2. TOSHIBA 10-in-1 Convection Toaster Oven
A budget-friendly 25-liter workhorse that adds rotisserie to the usual toaster-oven tricks.
The TOSHIBA delivers the most function per dollar in this lineup. At 1500W it undercuts the Gourmia’s 1700W, but it brings a rotisserie kit that the cheaper French-door model lacks — you can spin a whole chicken right on your counter. The 25-liter cavity fits a 12-inch pizza or a 4-pound bird, and the dropdown glass door makes loading easy. Owners mention “I’ve had it for a few weeks now, and I’m very satisfied with it.”
Ten cooking modes — from toast and bake to defrost and keep warm — cover nearly everything a family kitchen needs. The three control knobs with LCD displays are simple and tactile, with a satisfying detent feel that reviewers specifically call out. It preheats quickly and roasts vegetables beautifully, making it a solid pick for everyday meals.
The catch is in the details. The included baking pan sits smaller than the rack slots, which wastes interior space, and the rotisserie rack is described as flimsy. The crumb tray doesn’t catch rotisserie drippings, so you will wipe the interior after a spin. At 14.1 pounds it’s the lighter option in this class, easier to move than the KitchenAid’s 20.3 pounds.
Where it shines: rotisserie function at a budget-friendly price, plus a roomy 25-liter cavity that swallows a 12-inch pizza whole.
Where it cuts corners: the baking pan doesn’t fit the rack slots well, and the rotisserie setup needs a steady hand.
3. Gourmia French Door Air Fryer Toaster Oven
French doors that open wide, 17 presets, and 1700W of FryForce heat for crispy, oil-free meals.
The Gourmia is the pick for air-fry lovers who want a toaster oven that does double duty. Its 1700W convection system — the most powerful of the mid-range trio here, beating the TOSHIBA’s 1500W — circulates heat for crispy exteriors and juicy interiors with minimal oil. The 25-quart cavity fits a 12-inch pizza, six slices of toast, or a whole chicken, and the French door design opens wide for easy loading.
The digital display controls 17 presets, from air fry and roast to dehydrate and toast, with a temperature range of 90°F to 450°F and a timer up to 99 minutes. Customers note the FryForce 360 technology genuinely delivers — crispy fries and roasted chicken that taste like they came from a dedicated fryer. The included stainless steel fry basket, baking pan, oven rack, and crumb tray are all easy to clean.
You’ll find this oven easier to lift and store than the KitchenAid KCO255, since it weighs 13 pounds versus the KitchenAid’s 20.3 pounds. The trade-off: the French doors (which split in the middle and swing open from both sides) need clearance on both sides to open fully, and the interior is slightly smaller than the Oster’s 42 liters. For most families, this balances power and size well.
Why it’s a favorite
- 1700W FryForce convection for crispy results
- 17 presets and digital display
- Lightweight at 13 lbs
- Easy-clean basket and crumb tray
Before you buy
- French doors need side clearance to open
- Not as large as 42-liter models
Reach for this if: you want air-fryer crispiness without a separate countertop appliance.
Look elsewhere if: you routinely cook for six or more and need the biggest possible cavity — the Oster below has 17 more liters.
4. Oster Extra-Large 42L French Door Toaster Oven
The absolute giant of the group — 42 liters that hold two large pizzas or a full-size chicken with room to spare.
The Oster is for anyone who has ever cursed a too-small oven. Its 42-liter cavity is the largest in this lineup, easily swallowing 15×12-inch baking pans, two large pizzas, or a full-size chicken. That’s a massive step up from the TOSHIBA’s 25 liters, making it the pick for meal prepping or feeding a big household. The magnetized French doors stay open while you pull out your food, which is a genuinely thoughtful touch.
You get six presets — bake, toast, broil, warm, air fry, and turbo convection (a fan that speeds up hot air circulation) — so you can handle everyday meals without fiddling. The 60-minute timer with auto-shutoff turns the oven off when time’s up, so you won’t worry about leaving it on. Separate dials for function, time, and temperature keep controls simple. Reviewers point out it roasts a whole chicken with room to spare and heats fast enough to replace your main oven for daily cooking.
The honest trade-offs: a few shoppers say the oven gets hot on the outside, so give it clearance, and some received units with a dented body — worth checking your delivery. The temperature dials also lack position markers, which a couple of owners solved with a bit of white-out. If raw capacity is your top priority, nothing here comes close.
The standout: 42 liters of interior space fits two pizzas side by side — no other oven in this guide offers that much room.
The trade-off: exterior heat runs high and knobs lack position markers, so plan your counter placement carefully.
5. Ninja French Door Premier Air Fry Oven – FO101
The French door oven that preheats in 90 seconds and air-fries 5 pounds of fries in one go.
If you’re short on time, the Ninja FO101 heats up in 90 seconds — the quickest preheat in this guide — and its cyclonic air technology (a fan that spins hot air at high speed) is designed to cook up to 60% faster than a standard oven, according to the brand. The 20.3-quart interior fits a 5-quart air fry basket that holds up to 5 pounds of French fries, so you can feed a crowd. The French doors open with one hand, a feature buyers consistently praise.
Ten functions span air fry, air roast, dehydrate, and bagel, so you can cook a wide range of dishes. The included 5-quart basket, sheet pan, broil rack, and wire rack all go in the dishwasher for easy cleanup. The cooking surface is made without PFAS (a group of chemicals used in non-stick coatings), so you don’t have to worry about what touches your food. Buyers report crispy chicken wings and tender carne asada with no grease, and they call out even toasting as a standout.
At 22.8 pounds it’s heavier than the Gourmia’s 13 pounds, but it sits on the counter and earns its space. The recurring feedback is a wish for even more room — some owners find it perfect for one or two people but tight for a big family. The temperature settings get mixed reviews, so expect a little trial and error as you learn its rhythms.
Speed and ease
- 90-second preheat, fastest here
- 5-qt basket fits 5 lbs of fries
- One-handed French doors
- PFAS-free cooking surfaces
Consider this
- Smaller than 25L+ models
- Temperature settings get mixed reviews
Grab it for: quick weeknight air frying and toast — it replaces your toaster and your fryer at once.
skip it if: you need to roast a 12-pound turkey; the Ninja Prestige below handles that instead.
6. Ninja Prestige Smart XL Countertop Oven – DT501
A 1800W beast that fits a 12-pound turkey, bakes 20 cookies, and cooks on two levels at once.
For big family meals, the Ninja DT501 fits up to a 12-pound turkey — the largest single item any oven in this guide claims to hold — and bakes 20 cookies on two 9×9 trays at once. Its 1800W Smart Surround Convection system (a high-speed fan plus rear heat that wraps food in hot air) cooks evenly on two levels, so you don’t need to rotate or flip anything. If you cook for eight people regularly, this can replace your main oven.
Ten cooking programs cover air fry, air roast, broil, bake, whole roast, pizza, toast, bagel, reheat, and dehydrate. The 90-second preheat is a standout, and up to 30% faster cooking versus a full-size convection oven means dinner hits the table sooner. The digital display on the handle illuminates the optimal rack position for your chosen function — a clever touch that removes guesswork.
Owners mention cooking two pizzas at once and baking crispy sweet potato fries, all with easy cleanup. The trade-offs are real: at 33.6 pounds it’s the second-heaviest oven here, and the stainless finish smudges easily. All exterior surfaces get hot, so keep it away from edges, and note the air fry mode is louder than other settings. Buyers who switched from an Oster French door report far better durability.
Why it wins for big families: 2-level cooking with no flipping, plus room for a 12-pound holiday turkey.
Why it’s not for everyone: 33.6 lbs of counter-hogging steel, and the smudge-prone finish needs regular wiping.
7. Cuisinart Air Fryer Toaster Oven – TOA-95
An 1800W all-rounder with 14 cooking functions, a 0.95-cubic-foot cavity, and a 3-year warranty.
The Cuisinart TOA-95 packs the most functions in this guide — 14 in total, including air fry, bake, broil, toast, bagel, pizza, roast, dehydrate, proof, low, slow cook, dual cook, reheat, and warm. That covers techniques most other ovens here skip, like proofing bread dough. The 0.95-cubic-foot interior fits a 13-inch pizza or a 9×13-inch pan, and it can air fry up to 4 pounds of wings. The temperature range goes from a low 80°F (ideal for proofing dough) up to 450°F.
With an 1800W heating element, it’s among the most powerful ovens in this guide, and customers note it heats fast and cooks evenly. The large viewing window and interior light let you check on food without opening the door, and the baking pan and air fry basket are dishwasher-safe. It comes with a limited 3-year warranty and a PFAS-free interior, so you can use it daily with confidence.
Owners who upgraded from a Breville Smart Oven call this a big step up, praising the powerful convection and easy-to-clean interior. The main quirk: there’s no manual shut-off button — the oven auto-restarts its display after cooling down, and only unplugging fully resets it. That’s a minor annoyance in an otherwise top-tier performer that’s worth the premium.
The strengths
- 14 functions incl. slow cook and proof
- 1800W for fast, even heat
- 3-year warranty and PFAS-free interior
- Fits a 13-inch pizza
The quirks
- No manual shut-off button
- Runs hotter than some settings suggest
Choose this if: you want one appliance that proofs bread, slow-cooks a roast, and air-fries wings — all in a single footprint.
Be aware: the missing shut-off switch is a genuine quirk; plan to unplug it between uses.
8. KitchenAid Dual Convection Oven – KCO224
A 28-liter KitchenAid with dual fans and a no-flip air fry basket for hands-off crispy results.
The KCO224 is KitchenAid’s answer to air-fry fatigue. Its no-flip air fry basket eliminates the mid-cook shake that most fryer baskets demand, so you can set it and walk away. The dual convection fans circulate heat evenly, cooking chicken up to 20% faster than the standard bake setting on a 3-pound bird. The 28-liter cavity fits a whole tenderloin, a sheet cake, or the included 9×13-inch baking pan with room for a full one-pan dinner.
The built-in temperature probe alerts you when your meat hits the exact doneness you want, taking the guesswork out of roasts. Twelve cooking functions cover air fry, bake, dehydration, pizza, and dough proofing. Reviewers point out it preheats to 350°F in less than 4 minutes, and the quiet operation is a recurring compliment — much quieter than many rivals.
It runs hot to the touch on the exterior, which is expected for a metal oven, and one buyer flagged the front glass as a genuine burn hazard, so keep it away from curious kids. The preheat timer starts immediately at temperature, meaning you lose a minute loading your food. At 28 liters it matches the KCO255’s size, but the touch controls and no-flip basket make it the more modern choice for air-fry fans.
The best part: no-flip air frying with dual fans — genuinely hands-off crispy food.
The caution: the exterior gets hot enough to warrant a warning; keep young children clear and give it space.
9. Breville Joule Oven Air Fryer Pro – BOV950
The smartest oven in the guide — voice-activated, app-connected, and powered by Breville’s Element IQ system.
The Breville Joule is the premium statement piece of this list. Its Element IQ system uses five independent quartz elements and smart algorithms to steer power exactly where and when it’s needed, eliminating cold spots for restaurant-grade precision. The 16 x 13.5 x 7-inch interior is the biggest footprint here, and it comes with a 13-inch non-stick pizza pan, two reversible wire racks, a broiling rack, a 9×13-inch enamel roasting pan, and an air fry basket.
what separates it is the smart features. You can control it by voice with Google Assistant or Amazon Alexa — just say “set the oven to bake.” The Breville+ app includes over 1000 guided recipes from Epicurious, New York Times Cooking, Serious Eats, and America’s Test Kitchen, all tested for this specific oven. The automated multi-event cooking mode switches between modes on its own, so you press start and it does the rest, sending push notifications to your phone.
Quality is the most-discussed strength — 111 owners single it out as the reason to buy. It preheats fast to 475°F and holds temperature rock-steady. But it’s also the most expensive and heaviest option at 38.9 pounds, and durability gets mixed feedback with a few units arriving damaged. The top gets blazing hot in air fry mode, so a heatproof mat is recommended. If you want the pinnacle of smart countertop cooking and the price doesn’t faze you, this is the one.
Why it’s the flagship
- Element IQ: 5 elements, no cold spots
- Voice control via Alexa and Google
- 1000+ guided recipes in the app
- Biggest interior: 16×13.5×7 inches
The premium cost
- Most expensive and heaviest at 38.9 lbs
- Mixed durability feedback on arrival
- Top gets very hot — mat advised
Worth it for: the tech-savvy cook who wants guided recipes, voice control, and flawless even baking in one appliance.
pass on it if: you are happy turning a knob — the KitchenAid KCO255 delivers similar cooking quality for far less.
Understanding the Specs
Capacity: Liters, Quarts, and Cubic Feet
Manufacturers mix units, so do a quick mental conversion before comparing. A 25-quart oven is roughly 23.6 liters — the Gourmia and the TOSHIBA’s 25 liters are nearly identical in usable space. A 0.95-cubic-foot oven like the Cuisinart equals about 27 liters, which comfortably fits a 13-inch pizza. The literal biggest here is the Oster at 42 liters, which holds two full-size pizzas. As a rule, 25 liters fits a 12-inch pizza and a whole small chicken; 28+ liters adds room for a 9×13 pan; 42 liters handles a full holiday spread.
Power and Convection: The Even-Cooking Duo
Wattage tells you how fast the oven heats. The 1500W TOSHIBA is capable but slower than the 1800W Cuisinart and Ninja Prestige. Convection is the fan that circulates hot air, and it is the difference between a burnt edge and a golden crust. Dual convection, as in both KitchenAid models, uses two fans for even faster, more even heat — the KCO255 cooks chicken up to 20% faster than its own bake setting. If air frying matters, check the basket design: the KitchenAid KCO224’s no-flip basket beats models that demand a mid-cook shake.

Final Thoughts: The Verdict
The winner here is the KitchenAid KCO255 because it combines reliable cooking with a temperature probe (a metal sensor that tells you when meat hits the right internal temperature) that makes roasts simple to use — and it has the highest owner satisfaction in this group. If air frying is your priority, the Gourmia French Door delivers 1700W of crispy results at a mid-range price. And for the biggest family feasts, the Ninja DT501 is the one to reach for.
