Most kitchens have a toaster, an air fryer, a dehydrator, and a slow cooker shoved into cabinets gathering dust. The Breville BOV900BSS Smart Oven Air Fryer Pro exists because someone finally asked: what if one appliance did all of that, and did it well? After six weeks of roasting chickens, air-frying salmon, proofing dough, and dehydrating apple chips, we have a clear answer for who should spend $400 on a countertop oven.
Quick verdict
The Breville BOV900BSS is the best do-everything countertop oven you can buy. The Element iQ System delivers even browning and precise temperature control that cheaper models can't match. Super convection genuinely reduces cooking time by up to 30%. The tradeoffs are real—it's large, expensive, and the learning curve is steeper than a basic toaster oven—but for serious home cooks who want one appliance to replace four, this earns its spot on the counter.

Who is this for?
You cook at least three nights a week and want to consolidate appliances without sacrificing performance. You bake bread and need a warm spot for proofing. You make large batches of dehydrated snacks for kids. You host brunch and need to keep pancakes warm while cooking bacon. If any of those sound like your week, the BOV900BSS pays back quickly. If you just want something to toast bread, a $60 toaster oven does the job. This is for cooks who've graduated past single-purpose gadgets.
Key features
Element iQ System
Five independent quartz heating elements work with smart algorithms to direct heat where it's needed. Unlike basic toaster ovens with top and bottom coils that run constantly, Element iQ senses temperature across the cavity and adjusts power in real time. The result: no cold spots. When roasting a chicken, the breast and thighs finish at the same time rather than the breast overcooking while waiting for the thighs to catch up. Digital PID temperature control keeps the oven within a few degrees of the set temperature—crucial for baking cookies where a 20-degree swing means burnt edges and raw centers.
Super Convection
Two-speed convection fan (regular and super) circulates hot air throughout the cavity. Super convection cranks the fan speed and delivers a greater volume of air, cutting roasting and air-frying time by up to 30%. We tested this by cooking identical batches of frozen French fries: super convection produced golden, crispy fries in 18 minutes versus 25 minutes with regular convection. The high-volume air flow matters most for air frying and dehydrating, where moisture removal speed is the limiting factor.
13 Cooking Functions
Toast, Bagel, Broil, Bake, Roast, Warm, Pizza, Proof, Air Fry, Reheat, Cookies, Slow Cook, Dehydrate. That's not marketing—each function has a dedicated temperature range and preset logic. Proof runs at exactly 100°F with gentle heat. Slow Cook uses lower temperatures over extended times. Pizza function preheats to 500°F and directs heat specifically for a crisp bottom crust. Switching between functions resets the time and temperature defaults, so you're not accidentally air-frying at bake temperatures.
Capacity
The interior measures 16 x 13.5 x 7 inches. That fits nine slices of bread, a 14-pound turkey (for Thanksgiving prep), a 5-quart Dutch oven for slow cooking, and most 9x13-inch baking pans. Compare that to smaller air fryers that max out at a single layer of wings. The large capacity means you're not juggling batches. One pass through the oven handles a full sheet pan of vegetables for a family dinner.
LCD Display and Build Quality
The backlit LCD shows preheat status, current temperature, elapsed time, and function name. Preheating to 450°F takes about 10 minutes—faster than most full-size ovens, and you don't heat the whole kitchen in summer. The stainless steel housing wipes clean, and the interior light automatically activates at the end of cooking so you can check food without opening the door. Included accessories: 13-inch pizza pan, two oven racks, 9x13-inch broil rack, enamel roasting pan, and mesh basket for dehydrating.
Real-world performance
Three tests. First: whole roasted chicken, 4.5 pounds, seasoned and placed on the roasting rack. Set to Roast at 425°F. The bird came out with golden skin and even browning in 55 minutes—no adjustments, no rotating. Second: homemade sweet potato fries, tossed in oil and air-fried at 400°F on Super convection. Twelve minutes, single layer, crisp throughout. Third: sourdough proofing. Set to Proof, placed the covered dough on a rack, and forgot about it for 90 minutes. The gentle warmth brought the dough up without drying the surface. In each case, the oven did exactly what the function promised.
Pros and cons
See the structured breakdown in the product panel for detailed pros and cons. The BOV900BSS wins on versatility, temperature precision, and cooking speed. The main tradeoff is counter space—this thing is large. At 22 pounds and roughly 18 inches wide, it demands permanent counter placement or a dedicated cabinet for pulling out. The price tag also requires commitment: $400 is not impulse territory.
Verdict & price check
Buy it if you want one countertop appliance that handles toaster, oven, air fryer, and dehydrator without compromise. The Element iQ System and super convection deliver measurable improvements over cheaper models. Skip it if you only need a toaster or if counter space is genuinely limited.
