Bottom line
Choose Panasonic FlashXpress when a small footprint, 1,300-watt infrared heating system, and simple short timer matter most. Choose the Breville Smart Oven Air Fryer Pro when you will use its 13 functions, 13-inch pizza capacity, convection, and included racks and pans often enough to justify the counter space.
Cooks deciding whether they need a compact toaster or a true second oven.
You only need occasional toast and do not have room for a countertop oven.
The Panasonic FlashXpress and Breville Smart Oven Air Fryer Pro are both toaster ovens, but they represent opposite answers to the counter-space question. Panasonic keeps the footprint small with a 1,300-watt, four-slice oven, double infrared heaters, and a 0.5–25-minute timer. Breville is a larger stainless-steel countertop oven with 13 cooking functions and room for a 13-inch pizza or a 9-by-13-inch pan.
The useful comparison is therefore not which one has more modes. It is whether you need a compact appliance for toast and small meals, or a second oven that can roast, air fry, proof, dehydrate, and handle a larger tray.
Buy Panasonic for a compact toaster oven; buy Breville for a true second oven
These ovens are built around different amounts of ambition. Panasonic publishes a 13-by-12-by-10.2-inch outer size and a four-slice capacity; Breville publishes a 21.4-by-17.3-by-12.7-inch footprint and a 13-inch pizza or 9-by-13-inch pan capacity. The bigger oven is only better if you will use the room.
Panasonic FlashXpress 4-slice toaster oven
FlashXpress is the compact, quick-to-understand option. Panasonic publishes 1,300 watts, double infrared heaters, a 250–500°F temperature range, and a 0.5–25-minute timer. The product page lists a 13-inch width, 12-inch depth, and 10.2-inch height, with a 10.2-by-9.8-by-4.1-inch interior and one baking tray.
That specification set points to toast, bagels, frozen snacks, and small baking jobs rather than a second oven for a whole meal. The double infrared heater is the headline design difference, while the short timer and four-slice format keep the controls and footprint modest.
The value of a smaller oven
- FlashXpress is easier to leave on a small counter and easier to use when the job is one or two portions. The 10.2-inch interior width is a useful boundary: check your dishes rather than assuming every small baking pan will fit.
- The limitation is equally clear. A four-slice oven cannot replace a roomy countertop oven for a 13-inch pizza, a 9-by-13-inch tray, or several racks of food. It is a compact toaster oven, not an all-purpose second cavity.

Breville Smart Oven Air Fryer Pro
Breville takes the second-oven route. The Smart Oven Air Fryer Pro has 13 cooking functions, including toast, bagel, bake, roast, pizza, proof, air fry, reheat, cookies, slow cook, and dehydrate. Breville publishes a 21.4-inch width, 17.3-inch depth, and 12.7-inch height, along with a 13-inch pizza pan, two oven racks, a 9-by-13-inch broil rack and roasting pan, and a mesh air-fry/dehydrate basket.
The larger cavity changes what the appliance can replace on a busy day. Breville says it can fit a 13-inch pizza, a 9-by-13-inch baking pan, a 12-cup muffin tray, or a 14-pound turkey. Those are manufacturer capacity claims, not a promise that every kitchen needs them.
When the bigger cavity earns its footprint
- The Breville is the stronger match for cooks who want convection cooking, air frying, baking, and roasting in one countertop oven. Its included accessories also reduce the need to buy a separate rack or pan before using those modes.
- The cost is physical. Measure the full depth, door clearance, and space above the oven before buying. A feature-rich appliance that blocks a prep zone is not an upgrade for a small kitchen.

Who should buy FlashXpress, and who should buy the Smart Oven Pro?
Choose FlashXpress for toast and small portions
Panasonic is the practical choice when your oven jobs are toast, bagels, frozen snacks, and small plates. It takes less counter space and its 1,300-watt infrared design is easier to understand than a menu of 13 programs.
Choose Breville for a second-oven workload
Breville is worth the extra footprint if you routinely bake, roast, air fry, proof dough, or need to cook a 13-inch pizza or full-size tray without turning on the main oven. The included accessories make that larger brief more credible.
Skip the upgrade if the counter is the problem
Do not buy the Breville as a solution to a small kitchen if there is no safe place for it. Choose Panasonic when compactness is the actual requirement, or use your existing oven when neither appliance fits.

Panasonic FlashXpress is a compact four-slice, 1,300-watt toaster oven with double infrared heaters. Breville is a larger 13-function countertop oven designed for larger pans, pizza, roasting, air frying, and more.
Which toaster oven takes up less space?
Panasonic publishes a 13-inch width, 12-inch depth, and 10.2-inch height. Breville publishes a 21.4-inch width, 17.3-inch depth, and 12.7-inch height, so FlashXpress has the smaller footprint.
Can the Breville Smart Oven Air Fryer Pro fit a 9-by-13-inch pan?
Breville lists a 9-by-13-inch broil rack and enamel roasting pan among the included accessories and publishes that pan size as a capacity reference.
Does Panasonic FlashXpress need preheating?
Panasonic describes the FlashXpress double infrared heaters as providing instant heat that eliminates the need for preheating. Follow the manual for the specific food and setting.
Which one should a small kitchen buy?
Choose FlashXpress when compact toast and small portions are the job. Choose Breville only if the larger capacity and functions will replace enough main-oven work to earn the counter space.
