Shopping for a countertop oven under $300 is harder than it looks. Prices range from under $90 to well past $300, and spec sheets often leave out the details that matter most: how much usable space you get, what the oven draws in watts, and whether it has any real air-fry ability. Some brands publish all of that. Others publish almost none of it.

This guide helps you choose the best countertop oven under $300 based on what you actually cook. It covers baking, pizza, small kitchens and families. It also covers where the “air fryer” label is worth paying for.

How we evaluated these ovens: We did not lab-test them or cook in them. Recommendations come from manufacturer specifications, published documentation, and independent roundups, and I label editorial judgment as such. Prices change often, so confirm the final price on Amazon before buying. Our methodology note explains more.

Breville Smart Oven Pro (BOV845BSS)

Who should buy it: People who bake regularly and want controlled heat in a countertop oven.

What’s verified: Breville says it uses five quartz elements and 1,800 W. It lists ten functions (Toast, Bagel, Bake, Roast, Broil, Pizza, Cookies, Reheat, Warm, Slow Cook). Convection is built in and, per Breville, can cut cooking time by up to 30%. Slow cook runs up to 10 hours before switching to keep-warm. Included are one rack, a 12″ x 12″ enamel baking pan, a 12″ x 12″ broiling rack and a 13″ non-stick pizza pan. An LCD display and an interior light are included.

Baking and everyday use: The Cookies and Pizza presets, convection and a bundled 13″ pizza pan make this a sensible choice for sheet-pan baking and pizza. I can’t say how evenly it bakes, because we haven’t tested it. Independent roundups such as Coil & Convection rank it highly for baking based on specifications, including a published 120°F floor on Bake and Roast.

Capacity and space: At 18.9″ x 15.9″ x 10.9″ outside, it is smaller on the counter than the BLACK+DECKER, but Breville doesn’t publish a cubic-foot interior figure. Measure your pans first.

Controls and cleaning: The LCD interface is easy to use for most people. I haven’t verified crumb-tray or cleaning specifics from Breville’s page, so check the manual.

Pros: Strong feature set. Slow cook. 1,800 W. Good accessories.
Cons: No air fry. Interior volume unpublished. It’s the priciest pick here, close to the $300 cap.
Value: Reasonable if you’ll use the baking presets and slow cook. Paying more makes little sense if you only reheat and toast.
Who should avoid it: Anyone who wants air frying, since the Smart Oven Pro leaves that to Breville’s pricier air-fry models.
Verdict: The strongest all-rounder under $300 for bakers. Check Price on Amazon (insert link)

BLACK+DECKER 8-Slice Extra Wide (TO3250XSB)

Who should buy it: Budget-minded cooks who want convection baking and room for common pans.

What’s verified: BLACK+DECKER lists 1,500 W, a 2-year limited warranty, convection, and four functions (bake, broil, toast, keep warm). It fits a 13″ x 9″ pan with handles and a 12″ pizza. It has three rack positions, a 60-minute timer, and a dedicated toast timer. The listing includes a broiler pan and toasting rack, plus an external crumb tray.

Baking and everyday use: Being able to use the pans you already own is the draw. One thing to know: BLACK+DECKER states that temperatures inside run lower than the dial setting by design, with dials calibrated to compensate. That’s fine for casseroles and brownies. For precise baking, an oven with digital control may suit you better.

Capacity and space: It’s 22″ wide, so measure your counter and cabinet clearance.

Controls and cleaning: Simple dials and a removable external crumb tray keep cleaning and use straightforward.

Pros: Very low price. Published wattage and warranty. Fits standard pans.
Cons: Widest footprint here. No air-fry mode. Dial controls offer less precision.
Value: Excellent for what it is.
Who should avoid it: Small-kitchen shoppers and anyone who wants air frying or tight temperature control.
Verdict: The best budget pick for everyday cooking and casseroles. Check Price on Amazon (insert link)

Oster Extra Large 42 L French Door 6-in-1 (provisional pick)

Who should buy it: Larger households that want room and some air-fry capability.

What’s reported: The Amazon listing describes a 42-liter interior, French doors and a 6-in-1 function set with air fry. Oster doesn’t publish a wattage that I could find, and I could not verify price or specifications directly.

Fit and trade-offs: More space means more air to heat. For one or two people, a smaller oven may suit better. The doors open outward from the middle, so they clear less counter than a drop-down door.

Pros: Large capacity. Air fry included. Low price.
Cons: No published wattage. Specs unverified by me. Large footprint.
Value: Potentially strong if the price holds, but confirm the details yourself.
Who should avoid it: Single cooks and tight kitchens.
Verdict: Worth considering for families, with a verification step first. Check Price on Amazon (insert link)

Best Countertop Oven for Different Needs

• Cookies, cakes and bread: Breville Smart Oven Pro, based on its preset functions and element design (a spec-based judgment, not a test result).
• Pizza and reheating: The Breville ships with a 13″ pizza pan. The BLACK+DECKER fits a 12″ pizza.
• Small kitchens: The Breville has the smaller outside footprint of the three. The BLACK+DECKER is the widest.
• Families: The Oster’s 42 L cavity is the largest listed, pending verification.
• Air frying: Only the Oster lists it, and it’s provisional. The Breville Smart Oven Pro and BLACK+DECKER do not offer it.
• Lowest reasonable price: BLACK+DECKER.

Buying Guide: How to Choose a Countertop Oven Under $300

Capacity and interior dimensions. Exterior size and usable interior differ. Brands rarely publish both, so check what pan sizes the listing says will fit. Measure your most-used pan before ordering.

Temperature range and accuracy. Breville, for instance, publishes a 120°F low end on certain modes, which matters for slow cooking and proofing. Dial ovens like the BLACK+DECKER calibrate to approximate temperatures.

Convection versus conventional. Convection uses a fan to circulate hot air, which typically speeds cooking. Breville cites up to 30% faster cooking. Useful for roasting and browning, unnecessary if you mostly toast and reheat.

Air fry. Genuinely useful if you want crisp results often. If you won’t use it, don’t pay for it. Convection baking covers much of the same ground for casual users.

Wattage and electrical use. Breville lists 1,800 W and BLACK+DECKER 1,500 W. Both are significant loads on a standard household circuit. Avoid running other high-draw appliances on the same circuit, and follow the manual. Check the circuit rating in your kitchen if unsure.

Racks and accessories. Count included pans and racks, because replacements cost extra. BLACK+DECKER lists three rack positions.

Cleaning. A slide-out crumb tray makes upkeep easier. Wipe it regularly.

Footprint and clearance. Leave space around the oven for ventilation as your manual directs, and don’t tuck it under low cabinets while it runs.

Warranty. BLACK+DECKER lists two years. I couldn’t confirm Breville’s term from its product page; check its warranty page.

Your cooking and budget. If your oven would mostly toast, reheat and bake the occasional pan, you don’t need a $270 model. For the sources I drew on, see RTINGS’ testing, which covers small ovens and offers independent lab results beyond spec sheets.

Which Countertop Oven Is Best for You?

• You bake often: Breville Smart Oven Pro.
• You want the lowest price and bigger pans: BLACK+DECKER TO3250XSB.
• You cook for a larger household and want air fry: The Oster, after verification.
• You have a small kitchen: Measure first. The Breville has the smaller outside footprint here, but check our toaster oven guide for compact options.
• You want a big air fryer: See our air fryer picks, since none of the verified ovens here are dedicated air-fry models.
• You want to compare against the main list: See our broader countertop oven guide.

A bigger oven isn’t automatically better. It heats more air and takes more counter. Pick the size that matches your regular cooking.

How We Chose These Ovens

We researched manufacturer pages from Breville and BLACK+DECKER, plus independent roundups from Coil & Convection and RTINGS. We did not hands-on test any oven. Pick categories reflect specifications and are editorial judgments. Prices were checked on the research date and may have changed.

Frequently Asked Questions

What is the best countertop oven under $300 in 2026? For bakers, the Breville Smart Oven Pro at $269.95 is our top pick. For tight budgets, the BLACK+DECKER TO3250XSB at $86.99 is hard to beat.

Is a countertop oven worth buying? If you often cook small batches, yes. It can handle many jobs a full-size oven does without heating as much space.

Can a countertop oven replace a conventional oven? For most single-tray jobs, usually. For a turkey or several dishes at once, no.

Which is best for cookies and bread? The Breville Smart Oven Pro, given its cookie and bake settings and low-temperature range. This is a spec-based assessment.

Is convection better than a regular countertop oven? Convection usually cooks faster and browns more evenly, but it isn’t essential for toast or reheating.

Are air fryer toaster ovens worth the extra cost? Only if you’ll use air fry often. Otherwise, a convection oven is likely enough.

How much capacity do I need for a family? A cavity that fits a 13″ x 9″ pan and a 12–13″ pizza covers most families. The larger Oster may suit bigger households.

How much electricity does a countertop oven use? It depends on wattage and cooking time. The Breville is rated at 1,800 W and the BLACK+DECKER at 1,500 W, and they cycle on and off while cooking. Check your rate to estimate cost.

What should I look for when buying one? Interior fit for your pans, temperature control, wattage, accessories, cleaning ease and warranty.

How long should a good countertop oven last? There’s no reliable universal figure. Lifespan depends on the model and use, so check the warranty and read maintenance guidance.

Final Verdict

If you bake, cook regularly and can spend near the limit, the Breville Smart Oven Pro is the strongest pick here. Its main trade-off is that it has no air fry and sits close to the $300 cap. If budget matters most, the BLACK+DECKER TO3250XSB delivers convection baking for a fraction of the price, at the cost of precision and counter space. Verify the Oster before choosing it, and confirm all prices on Amazon.
