The French doors open with a single pull, and the magnetized door assist helps keep them open while you load or remove food. This door design can be useful when you need both hands for a heavy pan.
Six presets cover Bake, Toast, Broil, Warm, Air Fry and Turbo Convection. Separate controls for function, time and temperature keep the cooking settings distinct, and the 60-minute timer includes auto-shutoff.
The included accessories are an air fry rack, wire rack, baking pan and removable crumb tray. At 24.02 in wide and 15.28 in high, this oven needs more planning than the compact models.

Pros
- 10 cooking functions
- 3 rack positions
- Baking pan, crumb tray, wire rack and mesh rack included
Cons
- Less capacity than the 42L Oster
- Larger footprint than compact 4-slice ovens
The Oster 10 Function Air Fryer Oven Toaster is the best Oster countertop oven for varied cooking modes. Its 25L capacity fits a 12 in pizza while taking up less width than the 42L French Door model.
The 10 functions include air fry, bake, broil, defrost, dehydrate, pizza, roast, TenderRoast, toast and warm. TenderRoast is designed for low-temperature cooking of poultry, meat, pork and seafood.
Three rack positions let you adjust the cooking level for different foods. The digital display keeps the controls clear, while the baking pan, crumb tray, wire rack and air fryer mesh rack cover the main cooking tasks.
The oven measures 20.4 in D x 18 in W x 13.2 in H. Choose it when you want more cooking options than the 6-function Oster but don't need the 42L model's family-size interior.
How do Oster countertop oven capacities compare?
The 42L Oster has the most room, the 25L Oster balances capacity and features, and the Panasonic and BLACK+DECKER toaster ovens suit smaller portions. If color matters, compare our white toaster ovens.
Capacity should match your usual pan size, pizza size and number of servings.
The 42L model fits 15 x 12 in baking pans, two large pizzas and a full-size chicken. The 25L model fits a 12 in pizza, while the two 4-slice toaster ovens fit a 9 in pizza.
Capacity labels aren't the only measurement to check. Compare exterior width, depth and height with the open door or rack path, and leave enough room to load food safely.
Our guide to What Is a Countertop Oven? explains how these appliances differ from full-size ovens. If you want to understand the heating and cooking process, read How Does A Countertop Oven Work?.
Which countertop oven door design should you choose?
A French door gives the 42L Oster a wide opening from the center, while the other toaster ovens use dropdown doors. Microwaves use push-button or handle-style access rather than a toaster oven rack door.
The Oster French doors can be opened with one pull, and the door assist helps hold them open. This design may feel easier when you are placing a large pan, but the oven's wide body still needs substantial counter space.
The Panasonic, BLACK+DECKER toaster oven and 25L Oster use dropdown doors. Keep the front clear so the door can open fully and the rack can move forward without hitting nearby items.
Before choosing any model, measure the counter depth and the space above the appliance. Also check where hot air and heat will move during cooking.
Which cooking modes matter most?
Choose the Oster 42L for large meals and 6 broad cooking presets, or choose the 25L Oster for the widest mode list. The BLACK+DECKER 4-Slice Air Fry Toaster Oven is enough if you mainly need toast, air fry and basic baking.
The 25L Oster includes 10 functions, including defrost, dehydrate, pizza and TenderRoast. Those modes may reduce the need to switch between separate small appliances, but they also make the controls more involved.
The 42L Oster focuses on 6 functions and adds Turbo Convection. Its larger interior is the better match for meal prep, large pans and multiple servings.
The Panasonic takes a simpler approach with 6 auto cook options, reheat and defrost. The microwave models are more focused, with preset microwave foods and adjustable power levels rather than oven-style browning.
How should you set up and care for a countertop oven?
Set the oven on a stable, heat-safe counter with room for the door, rack and hot air. Remove crumbs after the oven cools, and use the crumb or drip tray when the model includes one.
The Panasonic, BLACK+DECKER toaster oven and Oster models include removable trays or racks that help with routine cleanup. Follow the appliance instructions for removing parts and cleaning surfaces.
Keep food clear of heating elements and use the correct pan or rack for the selected function. For air frying, use the supplied mesh tray where applicable and allow air to circulate around the food.
A microwave needs different care. Keep the glass turntable seated correctly, clean spills after the oven cools, and use the child safety lock when it helps your household routine.
Final verdict: which is the best Oster countertop oven?
The best Oster countertop oven is the 42L French Door model if you cook family-size meals, use 15 x 12 in pans or want space for two large pizzas. Choose the 25L Oster if 10 cooking functions and a smaller width matter more than maximum capacity.
Choose the Panasonic FlashXpress for a compact 4-slice oven, or the BLACK+DECKER Air Fry Toaster Oven for compact air frying. Pick the Chefman or BLACK+DECKER microwave when reheating and microwave presets are your main needs.
