Breville Mini Smart Oven BOV450 Review: Worth the Counter Space?
· NookPrep Editorial Team
The Breville Mini Smart Oven is small by countertop-oven standards, but it is not a tiny appliance. That distinction matters in a compact kitchen. At 16 × 13.6 × 8.8 inches, it asks for noticeably more counter space than a mini air fryer, yet it can toast four slices, bake, broil, roast, reheat, and handle an 11-inch pizza.
NookPrep Verdict
Best for: small kitchens that need one countertop appliance to cover toast, baking, reheating, pizza, and light oven duties.
Skip it if: your main priority is the smallest possible footprint or you specifically want air-fryer-style crisping.
Bottom line: the Breville Mini Smart Oven earns more space than a tiny toaster because it can replace several jobs, but the 16-inch width means you should measure first.
Editorial note: this review is based on verified Breville specifications, product design, capacity, and small-kitchen use cases. NookPrep did not independently lab-test this oven.

Is It Actually Small Enough for a Small Kitchen?
The word “Mini” can create the wrong expectation. This is not a narrow single-slot toaster and it is not as compact as a 2-quart air fryer. The footprint is still significant, especially the 13.6-inch depth. In a galley kitchen, depth often matters as much as width because an appliance can consume the entire usable strip between the backsplash and the counter edge.
Where the Breville makes its case is replacement value. If it lets you avoid owning a toaster, a separate small baking appliance, and perhaps reduces how often you use a full-size oven, the space equation can work in its favor.
Before buying, compare it with our air fryer vs toaster oven for small kitchens guide. The better appliance depends on whether you prioritize crisping speed or broader oven-style cooking.
Eight Functions Without a Giant Control Panel
Breville includes Toast, Bagel, Bake, Broil, Pizza, Roast, Cookies, and Reheat. These are meaningful modes rather than decorative presets because they map to common countertop-oven jobs.
The backlit LCD also helps the oven feel less fiddly than basic dial-only toaster ovens. Breville’s Element IQ system controls four quartz heating elements and adjusts heat distribution for the selected function. The key benefit for a small-kitchen owner is not the technology label itself; it is getting a wider range of cooking tasks from one appliance.
Capacity: Four Slices and an 11-Inch Pizza
Breville says the Mini Smart Oven can hold four slices of toast and an 11-inch pizza. That capacity is useful because it moves the appliance beyond “fancy toaster” territory without making it physically enormous.
For one or two people, that can cover breakfast, open-faced sandwiches, reheating, cookies, small roasted portions, and frozen pizza. It is not a substitute for a full oven when you need large bakeware or multiple racks.
1800W Power: Fast, but Check Your Outlet Setup
The 1800W rating is one reason the oven can preheat quickly, but it also means this is a high-draw countertop appliance. In an older apartment or a kitchen where a microwave, kettle, and coffee maker share the same circuit, you should avoid running several high-wattage appliances simultaneously.
This is not a flaw unique to Breville; many countertop ovens draw substantial power. It is simply more important to think about in compact kitchens where appliances tend to share a small number of outlets.
Where It Beats a Mini Air Fryer
The Breville has the advantage when you want toast, bagels, pizza, cookies, baked dishes, or food that benefits from a wider flat cooking surface. You can see the food through the door, use a small baking pan, and work with shapes that do not fit comfortably in a basket.
A small air fryer generally wins when your priorities are the smallest footprint and aggressive hot-air crisping. If you mostly cook frozen fries and single portions, our compact air fryer guide may point you toward a better use of space.
Pros and Cons
Pros
- Eight genuinely useful cooking functions
- Fits an 11-inch pizza
- Four-slice toast capacity
- LCD controls are easy to read
- Can replace several basic countertop jobs
- Low 8.8-inch height helps under cabinets
Cons
- 16-inch width is not truly tiny
- 13.6-inch depth needs real counter space
- 1800W power draw is substantial
- No dedicated air-fry function
Who Should Buy the Breville Mini Smart Oven?
This is a strong choice for a one- or two-person kitchen that values versatility more than the absolute smallest footprint. It makes the most sense when you want a countertop oven to handle breakfast, reheating, pizza, baking, and light roasting without turning on a full-size oven.
If your counter is extremely narrow, measure before ordering. Our best compact toaster ovens guide can help compare the footprint with other options.
Final Verdict
The Breville Mini Smart Oven BOV450 is compact relative to what it can do, not compact in the “barely uses counter space” sense. If eight useful oven functions can replace multiple appliances in your routine, it can justify its footprint. If you only need toast or single-portion crisping, a smaller appliance will be easier to live with.
