1. Design & Countertop Footprint
The Breville Smart Oven Air Fryer Pro features a brushed stainless steel exterior that fits seamlessly alongside modern kitchen setups. Built with commercial-grade aesthetics, it feels sturdy, responsive, and engineered for heavy daily use.

Physical Specifications
- Height: 12.7 inches
- Width: 21.5 inches
- Depth: 17.5 inches
- Interior Volume: 1.0 cubic foot
- Construction: Brushed Stainless Steel
While it requires dedicated space on your counter, its 1.0 cu. ft. internal capacity replaces multiple standalone appliances like traditional air fryers, dehydrators, and pop-up toasters.
2. Cooking Capacity & Daily Versatility
Capacity is where this unit outperforms standard toaster ovens. The spacious interior accommodates heavy cookware, large baking sheets, and high-volume meal prep.

You can comfortably fit:
- A full 14 lb turkey or whole chicken.
- A standard 5-quart Dutch oven with lid.
- A 12-cup muffin pan.
- Up to 9 slices of bread simultaneously.
Whether you are preparing family holiday meals or batch-cooking weekly proteins, the interior height and rack placement options keep food from burning near the top elements.
3. Element IQ System & 13 Smart Cooking Functions
At the heart of the appliance is Breville’s proprietary Element IQ System. Six independent quartz heating elements direct power exactly where and when it is needed, eliminating hot spots and ensuring uniform heat distribution.

The high-contrast LCD screen provides clear navigation across 13 dedicated functions:
- Toast & Bagel: Precise shade controls for uniform browning.
- Bake, Roast & Broil: High-heat searing and slow roasting capabilities.
- Air Fry & Super Convection: High-speed airflow to crisp food quickly with minimal oil.
- Dehydrate & Proof: Low-temperature control for drying fruits, jerky, or rising bread dough.
- Slow Cook & Warm: Extended gentle heating for tender meats and soups.
4. Multi-Level Air Frying and Dehydrating Performance
Unlike standard pod-style air fryers that limit capacity, the BOV900BSS allows multi-rack cooking. Utilizing two airflow speeds (Standard and Super Convection), it maximizes hot air movement around every tray.

With four dedicated rack positions, you can air fry large batches of fries, crisp chicken wings, or dehydrate up to four full trays of snacks at once without rotating trays mid-cycle.
5. Connected Experience with Breville+

The appliance integrates with the Breville+ mobile platform. The app offers step-by-step guided recipes, video tutorials created by professional chefs, and customized cooking profiles designed specifically for the BOV900BSS to deliver consistent results every time.
