The deciding factor between the Breville Smart Oven Air Fryer Pro and the Instant Omni Plus is whether you prioritize massive cookware capacity with digital thermal precision or dedicated rotisserie roasting in a slightly more compact footprint.
Choose the Breville if you want to bake in standard 9×13-inch pans, slow-cook with a Dutch oven, and control multi-stage heat across five quartz elements; choose the Instant Pot Omni Plus if you want self-basting rotisserie chicken and dishwasher-safe accessories for fast weeknight dinners.

Cooking Capacity and Usable Interior Space
Interior volume dictates what bakeware can move directly from your kitchen cupboards into a countertop appliance. The Breville smart oven air fryer pro capacity measures 16 by 13.5 by 7 inches, providing sufficient clearance for standard 9×13-inch baking pans, a 12-cup muffin tray, a 14-pound turkey, or a 5-quart lidded Dutch oven. Because the interior spreads out horizontally and provides multiple rack positions, it can also toast nine slices of sandwich bread simultaneously or dehydrate food across four discrete levels using extra wire shelves.
The Instant Omni Plus utilizes an 18-liter (19-quart) cavity rated to handle six slices of toast or a 12-inch pizza. While its exterior height of 13.89 inches gives it decent vertical room, the base interior dimensions of roughly 12 by 12 inches cannot accommodate wide, handled baking dishes or standard sheet pans. When evaluating the breville smart oven air fryer pro vs instant pot omni plus for everyday meal preparation, the difference means cooking a whole casserole in a single standard dish versus dividing recipes into smaller, oven-safe vessels.
For cooks who prepare meals for large households or frequently host dinner gatherings, the expanded interior of the Breville oven eliminates the need to run multiple batches. The Instant Omni Plus manages family-sized portions for standard proteins, but its smaller footprint restricts your cookware choices to compact accessories and smaller baking tins.
Edge: Breville Smart Oven Air Fryer Pro because its 16-by-13.5-inch interior accepts standard 9×13-inch baking pans, 12-cup muffin trays, and 5-quart Dutch ovens that cannot fit inside the Omni Plus.
Heating Technology and Baking Performance
Baking requires uniform heat application to ensure risen doughs cook through without scorched crusts or underbaked centers. The Breville Smart Oven Air Fryer Pro relies on the Element iQ system, which deploys five independent quartz heating elements managed by smart algorithms and digital PID temperature control. The system dynamically redistributes power to eliminate cold spots, adjusting element wattage output automatically as food cooks. Its broad temperature spectrum spans from 80°F up to 480°F, allowing the appliance to operate as a low-temperature yeast proofing box or an intense pizza oven.
The Instant Omni Plus utilizes Golden Quartz Infrared heating elements that focus dual radiant heat onto the cooking surface, paired with an operating range of 85°F to 450°F. The listing highlights minimal preheating time, making it convenient for quick weeknight bakes. However, it lacks the multi-element dynamic distribution found in Breville’s PID-managed system. When comparing the breville smart oven air fryer pro or instant omni plus for baking, the Breville provides superior temperature stability for delicate soufflés, layer cakes, and laminated pastries.
Furthermore, Breville includes dedicated presets for Proof, Cookies, and Bake, each tailored to fire individual heating elements at specific power percentages. The Omni Plus provides consistent radiant heat for everyday casseroles and baked chicken breasts, but its top temperature tops out 30 degrees lower, which reduces oven spring when baking artisan breads or blistering pizza crusts.
Edge: Breville Smart Oven Air Fryer Pro due to its five independent quartz elements and digital PID controller that actively balance heat to prevent cold spots.
Rotisserie and Specialized Roasting Capabilities
Rotisserie cooking uses continuous rotation beneath radiant heating elements to self-baste whole meats, yielding crisp skin and tender interior meat. The Instant Omni Plus includes a dedicated barbecue-style rotisserie spit and motorized drive socket built right into the interior wall. This allows you to secure whole chickens, pork loins, or beef roasts onto the prongs and roast them as they turn slowly beneath the infrared quartz elements. Fat renders across the rotating exterior rather than pooling below, creating a self-basting cycle that standard stationary roasting pans cannot match.
The Breville Smart Oven Air Fryer Pro does not have a rotisserie spit, motorized gear, or mounting brackets. Instead, it handles large meats using its dedicated Roast and Slow Cook settings, relying on its spacious interior to fit up to a 14-pound turkey or a 5-quart Dutch oven placed on a stationary wire rack. While this setup roasts large cuts evenly thanks to the surrounding convection airflow, it requires manual turning or basting if you want uniform crisping across the bottom surface.
If your primary motivation for buying a multi-function countertop cooker is preparing market-style rotisserie chicken at home, the choice between the breville smart oven air fryer pro or instant omni plus for rotisserie is straightforward. The instant omni plus rotisserie spit provides an automated motorized roasting method that the Breville is simply not engineered to perform.
Edge: Instant Omni Plus because its motorized rotisserie spit continuously self-bastes whole poultry and roasts for even crisping.
Air Frying and Convection Power
Convection systems rely on fans to circulate heated air throughout the oven chamber, stripping away surface moisture to produce crisp textures without deep frying. The Breville Smart Oven Air Fryer Pro features Super Convection technology powered by a two-speed fan. The super convection setting dramatically increases the volume of circulating hot air, which the manufacturer states reduces overall cooking time by up to 30 percent. Paired with the included wide mesh air-fry basket, the intense airflow circulates around family-sized batches of French fries, wings, and vegetables, and supports dehydrating across up to four trays simultaneously.
The Instant Omni Plus employs EvenCrisp technology paired with infrared radiant heat, circulating hot air to deliver crisp textures while using up to 95 percent less oil than deep frying. Much like the convection systems evaluated in our breville smart oven air fryer pro vs cuisinart toa-60 comparison, the Omni Plus concentrates its air circulation within a compact chamber, producing rapid crisping on smaller batches of frozen foods and battered snacks.
While both machines output 1800 watts of power, Breville’s two-speed fan gives users more nuanced control over air velocity. The lower convection speed prevents delicate batters or meringues from shifting on the tray, while the super convection setting maximizes crisping. The Instant Omni Plus provides effective air frying for everyday side dishes, but Breville’s wider mesh basket spreads food out into a single layer over a larger surface area, preventing the steaming that occurs when food is crowded.
Edge: Breville Smart Oven Air Fryer Pro because its two-speed super convection fan circulates higher air volumes over a wider mesh tray.
Preset Versatility and Interface Usability
An intuitive interface simplifies navigating multiple cooking methods without consulting instruction manuals for every meal. The Breville Smart Oven Air Fryer Pro provides 13 dedicated cooking functions: Toast, Bagel, Broil, Bake, Roast, Warm, Pizza, Proof, Air Fry, Reheat, Cookies, Slow Cook, and Dehydrate. Each function automatically selects the ideal element configuration and fan speed. Its front panel features an LCD screen that turns blue during operation and orange while preheating, indicating when preheat is complete and automatically beginning the cook timer countdown. Physical knobs provide tactile adjustment over time, temperature, and rack placement reminders.
The Instant Omni Plus features 10 core cooking functions: Air Fry, Broil, Bake, Roast, Dehydrate, Reheat, Rotisserie, Toast, Warm, and Convection. As explored across modern multi-cooker interfaces in the cuisinart toa-60 vs instant omni plus evaluation, the Omni Plus features programmable digital controls with minimal preheat delays. The listing also identifies app control compatibility, allowing tech-oriented users to monitor or manage cooking parameters digitally.
In everyday use, Breville’s specialized settings for proofing dough, slow cooking stews, and baking cookies reduce guesswork. The clear visual cues on Breville’s display-specifically the preheat completion alert that triggers the timer countdown-prevent food from being loaded into a cold cavity. While the Omni Plus covers the essential countertop functions effectively, Breville’s expanded menu gives it an edge for complex multi-stage recipes.
Edge: Breville Smart Oven Air Fryer Pro because its 13 presets include specialized Proof and Slow Cook functions alongside an LCD display with automated countdown tracking.
Build Quality, Accessories, and Cleaning
Countertop appliances must endure high thermal stress, frequent grease exposure, and regular cleaning routines. The Breville Smart Oven Air Fryer Pro is built with a brushed stainless steel exterior, an integrated interior oven light with replaceable components, and heavy-duty dial controls. It ships with an extensive accessory package: a 13-inch pizza pan, two wire oven racks, a 9×13-inch broil rack with an enamel roasting pan, and a dedicated mesh basket for air frying and dehydrating. The unit is backed by a 2-year limited manufacturer warranty, reflecting commercial-leaning component durability.
The Instant Omni Plus features a stainless steel finish over a plastic housing framework, combined with a double-layer glass door engineered to trap heat inside the chamber and keep exterior surfaces cooler. For cooks examining multi-cooker maintenance requirements-similar to those detailed in our instant pot duo crisp vs pro plus and cosori dual blaze vs instant vortex plus guides-the Omni Plus offers a major cleaning advantage: its enamel baking tray, air fry basket, and rotisserie hardware are explicitly dishwasher safe.
Breville recommends hand-washing its accessories to maintain their enamel and non-stick finishes, which requires extra kitchen cleanup effort. However, the Breville oven incorporates an interior light that automatically turns on at the end of cycles and can be replaced by the owner if the bulb burns out over years of use. Breville’s all-metal construction and two-year warranty offer better long-term durability, whereas the Omni Plus emphasizes low-effort daily cleanup.
Edge: Breville Smart Oven Air Fryer Pro for its all-metal chassis, replaceable interior light, dual wire racks, and 2-year warranty coverage.
