Oster is a long-running American small-appliance brand, and its countertop toaster ovens are a common first purchase for new apartments, college graduates and couples setting up a kitchen. If you searched for “oyster toaster ovens,” you are in the right place: “oyster” is one of the most common misspellings of Oster, and the ovens below are the Oster models people usually mean. Every one of them also works as an air fryer, which means a powerful fan blows hot air around the food so it crisps up with little or no oil.
The three models differ mainly in size and number of functions: the French Door is the extra-large 42-liter family oven, the 10 Function model is a mid-size 25-liter oven with the most cooking modes, and the Compact is a 17-liter oven with five simple functions for small spaces.

Oster Extra-Large 42L French Door Countertop
Best for: Big families and weekly meal preppers
Pros
- 42L fits two large pizzas
- French doors with magnetic assist
- 6 presets incl. Turbo Convection
- Separate function, time, temp knobs
Cons
- Largest countertop footprint
- Fewer presets than 10-function
The Oster Extra-Large 42L French Door Countertop Toaster Oven is the biggest oven in the lineup and the one to look at if you regularly cook for a crowd. “French door” means two side-by-side doors that swing outward like a small cabinet instead of one door that drops down. On this model both doors open with a single pull, and a magnetized door assist keeps them open while you take food out, so you are not reaching over a hot door.
Inside, the listing says it fits 15 by 12 baking pans, two large pizzas or a full-size chicken, which makes it realistic for weekly meal prep or a holiday side dish when the main oven is full. It has 6 presets: Bake, Toast, Broil, Warm, Air Fry and Turbo Convection. Convection simply means a fan circulates hot air for faster, more even cooking, and “turbo” convection pushes that air harder. The listing also says air frying uses 99.5% less oil compared to deep fryers. It runs at 1700 watts.
Controls are simple, with separate knobs for cooking function, time and temperature, plus a 60-minute timer with auto-shutoff. Accessories include an air fry rack, a wire/broil rack, a baking pan and a removable crumb tray. This model suits families, meal preppers and anyone who wants a true second oven on the counter. Its trade-off is space: it needs a lot of counter room, and it has fewer presets than the 10 Function model, so cooks who want to dehydrate fruit or slow-roast meat should look next.
Oster 10 Function Air Fryer Oven for Versatile Cooking

Oster 10 Function Air Fryer Oven
Best for: Cooks who want dehydrate and slow roast
Pros
- 10 cooking functions
- TenderRoast low-temp mode
- Fully digital display
- Fits a 12-inch pizza
Cons
- Wattage not listed
- Drop-down door only
The Oster 10 Function Air Fryer Oven sits in the middle for size, with a 26-quart (25-liter) capacity that fits a 12-inch pizza without taking over the counter. Its main appeal is variety: it can air fry, bake, broil, defrost, dehydrate, cook pizza, roast, TenderRoast, toast and warm. That is the widest range of functions among these three ovens.
TenderRoast is Oster’s low-temperature setting for poultry, meat, pork and seafood, designed for fall-off-the-bone results, a bit like a slow cooker inside a toaster oven. The listing says the oven uses additional heating elements and a perforated interior to improve air frying. It has three rack positions, so you can cook two foods at once, and a fully digital display rather than knobs. Accessories include a baking pan, crumb tray, wire rack and air fryer mesh rack. The listing does not specify its wattage or maximum timer length, and it uses a standard drop-down door.
This model suits the curious cook who wants to try dried fruit, jerky or slow-roasted chicken without buying more appliances. If you mostly toast and reheat, its extra buttons may be more than you need, and the Compact is simpler. If you need to fit two pizzas at once, step up to the French Door.

Oster Compact Air Fryer Toaster Oven.
Best for: Small kitchens, dorms and first apartments
Pros
- Compact 17L body
- Simple manual controls
- 60-minute timer
- Four accessories included
Cons
- 5 functions only
- Fits 9-inch pizza max
The Oster Compact Air Fryer Toaster Oven. is the smallest model, with an 18-quart (17-liter) capacity. The listing says it fits a 9-inch pizza or a whole chicken and toasts 4 slices, while freeing up counter space. The description also mentions cooking an entire meal for a family of six, which seems generous for an oven this size, so treat it as a best-case claim rather than an everyday expectation.
It keeps things simple with 5 functions: air fry, bake, broil, toast and warm. Turbo Convection Heat Technology handles the air frying, again with 99.5% less oil than deep frying according to the listing. You set it with easy manual controls and a 60-minute timer. It runs at 1400 watts, has three rack positions and comes with a baking pan, crumb tray, wire rack and air fryer mesh rack. The removable crumb tray makes cleanup easy, which beginners tend to appreciate.
This is the best fit for a dorm, studio apartment or first kitchen, and it makes a practical housewarming gift. Anyone who wants to dehydrate or slow-roast should pick the 10 Function model instead, and anyone feeding a big household should look at the French Door.
How to Choose the Right Oster Toaster Oven
Start with size, because it decides both what you can cook and where the oven will live. A liter measurement tells you how much air space is inside. The 17-liter Compact handles a 9-inch pizza and toast for a small household. The 25-liter 10 Function model fits a 12-inch pizza. The 42-liter French Door fits two large pizzas or a 15 by 12 baking pan. Measure your counter, and leave room around the oven for heat to escape.
Next, count the functions you will actually use. If toast, bake, broil, warm and air fry cover your cooking, the Compact does the job. If you want dehydrating, defrosting or a slow TenderRoast mode, only the 10 Function model lists them. The French Door adds a Turbo Convection preset but keeps a shorter list overall. If air frying is your main goal and you are open to other styles, our basket air fryer guide covers a different kind of machine.
Then think about controls. Knobs, as on the French Door and the Compact, are quick and easy for beginners and older relatives. The 10 Function model uses a digital display, which some people find cleaner and others find fussier.
Finally, consider how often you make pizza. The French Door fits two large pies, while the 10 Function fits a 12-inch pizza and has a dedicated pizza setting. Pizza lovers who want a very hot dedicated appliance can read our guide to an electric pizza oven.
