We’ve cooked everything from frozen pizza to roasted chicken in three different Oster toaster ovens over the past month. The goal was simple: find which old Oster toaster oven (or the current version that feels like the old classic) still earns a spot on your counter. After a full weekend of baking cookies, air-frying fries, and broiling fish, one model clearly out-cooked the others.
Our top pick is the Oster 10 Function Air Fryer Oven. It handled everything we threw at it with even heat, quick preheating, and zero hot spots — something we can’t say for the other two.

How We Tested These Toaster Ovens
Our culinary team consulted with professional chefs and cross-referenced our hands-on stress tests with long-term user feedback to verify durability claims. We ran each oven through identical cooking challenges: a full sheet of toast (checking evenness across all slices), frozen pizza (crispness of crust vs. burning on top), and a whole chicken (juiciness and cook time). We also measured surface temperature after 30 minutes of use and noted any hot spots using an infrared thermometer. The testing took place in our standard kitchen setup over the course of a week, with each oven used for at least five full cooking sessions.
Oster 10 Function Air Fryer Oven (Best Overall Performance)
Here’s the deal: If you want the most versatile Oster toaster oven that actually cooks evenly, this is it. The 26-quart capacity fits a 12-inch pizza without crowding, and the perforated interior — combined with extra heating elements — delivers noticeably crispier air-fried food than the compact model.
The first thing we noticed was the weight. This thing has a solid heft — the door closes with a satisfying metal-on-metal click, not a plastic rattle. The stainless steel body stayed cool to the touch even after running the air fry cycle at 400°F for 20 minutes. During our toast test, all six slices came out evenly golden — no pale corners or burnt edges. The 10 cooking functions include dehydrate and tender roast, which we actually used to make beef jerky and a small pork loin. Both came out better than expected for a countertop oven.
Over the course of a week, the only annoyance was the timer dial. It’s analog and slightly stiff, making it tricky to set exactly 12 minutes vs. 15. Also, the interior light is dim — you’ll need to open the door to really see what’s happening. But for the cooking performance alone, this oven justifies its counter space.
Pros:
- Even heating — No hot spots in our toast or pizza tests; every slice came out consistent.
- Solid build — The stainless steel door and body feel premium, and the door hinge is sturdy.
- 10 functions are genuinely useful — Dehydrate and tender roast are rare at this price point and actually work.
Cons:
- Stiff timer dial — Hard to set precise minutes; you’ll overshoot and have to dial back.
- Dim interior light — Barely illuminates the food; you’ll still open the door to check.
- Large footprint — At 26 quarts, it takes up significant counter space; not for tiny kitchens.
Our Take
Great match for: Home cooks who want one appliance to replace a toaster, air fryer, and small oven. Think twice if: You have limited counter space or only need basic toast and reheating — the compact model will suit you better.
Oster Compact Air Fryer Toaster Oven (Best for Small Kitchens)
In a nutshell: This 18-quart oven is built for tight spaces. It fits a 9-inch pizza or a small whole chicken, and the Turbo Convection Heat Technology pushes hot air around aggressively — fries came out crispy on the outside and fluffy inside.
Right out of the gate, the compact size is its biggest selling point. It’s narrow enough to sit between a coffee maker and a knife block on a standard counter. But the trade-off is that the heating elements are closer to the food. During our first batch of toast, the top row of slices browned faster than the bottom — a clear hot spot issue. Rotating the tray halfway helped, but it’s an extra step you shouldn’t have to take. The five cooking functions (air fry, bake, broil, toast, warm) cover the basics, but you won’t get dehydrate or roast modes.
After a week of daily use, the non-stick interior was easy to wipe clean — a major plus. The crumb tray slides out smoothly and catches most debris. Our biggest gripe is the lack of a convection fan switch; it runs on every mode except toast, which can dry out delicate baked goods if you’re not careful. For quick meals and single servings, though, this oven gets the job done without hogging your counter.
Pros:
- True space-saver — At 18 quarts, it fits in tight spots where the 10-function model won’t.
- Easy to clean — Non-stick interior and a well-designed crumb tray make post-cooking cleanup fast.
- Good air fry performance — Turbo convection delivers crispy results on fries and chicken wings.
Cons:
- Uneven toasting — Top rows brown faster; you’ll need to rotate the tray for consistent results.
- No convection toggle — The fan runs on all modes except toast, which can dry out muffins and pastries.
- Limited functions — Only 5 cooking modes; no dehydrate or slow roast options.
Final Thoughts
Ideal for: Dorm rooms, small apartments, or anyone who needs a basic toaster oven with air fry capability. Pass on this if: You cook for more than two people regularly or need precise, even toasting every time.
Toaster Oven Replacement Trays Compatible with Oster (Best for Reviving Older Models)
Why it made our list: If you own an Oster toaster oven older model that still heats well but has warped or rusted trays, this set of replacement trays can extend its life. Made from carbon steel, these trays conduct heat quickly and evenly — we tested them in a 2018 Oster oven and they fit perfectly.
The first thing we noticed was the weight. These are not flimsy, thin sheets — the carbon steel feels sturdy, with rolled edges that won’t cut your hands. We ran them through a high-heat air fry cycle at 425°F and they showed zero warping. The non-stick coating released frozen chicken tenders without sticking, and cleanup was a quick wipe with a damp cloth. The set includes a baking pan, a broiler pan, and a wire rack, covering most cooking needs.
However, the fit is not universal. We tried them in a 2020 Oster compact model and they were slightly too long — they didn’t slide in all the way. Oster has changed tray dimensions over the years, so measure your existing tray before ordering. Also, the non-stick coating is not oven-safe above 450°F, so no broiler use directly under the heating element. For basic baking, roasting, and air frying, these trays are a solid value.
Pros:
- Sturdy carbon steel — No warping at high heat; feels much more durable than the original trays.
- Good heat conduction — Even browning on cookies and roasted vegetables during our tests.
- Easy release — Non-stick coating worked well with frozen foods and minimal oil.
Cons:
- Fit is model-specific — Not all Oster ovens use the same tray dimensions; measure first.
- Coating temperature limit — 450°F max means no direct broiler use; use the wire rack instead.
- Only three pieces — No pizza pan or additional racks included; you may need more for full meals.
Our Verdict
Perfect for: Anyone with a functioning older Oster oven that needs fresh trays. Not great if: Your oven itself is failing — these trays won’t fix broken heating elements or a faulty thermostat.
Buying Guide: What to Look for in an Old Oster Toaster Oven
Choosing the right Oster toaster oven — whether you’re buying new or keeping an older model running — comes down to three things: capacity, cooking functions, and evenness of heat.
Capacity vs. Counter Space
Oster’s 26-quart models (like our top pick) can handle a 12-inch pizza or a whole chicken, but they need about 18 inches of counter depth. The 18-quart compact model fits in tighter spots but limits you to a 9-inch pizza. Measure your space before buying — nothing’s worse than an oven that overhangs your counter edge.
Cooking Functions: More Isn’t Always Better
The 10-function oven includes dehydrate and tender roast, which are genuinely useful if you meal prep or make snacks. The 5-function compact covers the basics. If you only toast and reheat, the simpler model saves money and counter space. If you want to air fry, bake, and roast, the extra functions are worth it.
Old Oster Toaster Oven Maintenance Tips
If you’re keeping an older model running, replacement trays (like the ones we tested) are the most common fix. Also check the door seal — if it’s loose, heat escapes and cooking times increase. A quick wipe of the heating elements with a dry brush every few months prevents smoke and uneven heating.
Our Final Recommendation
For most people, the Oster 10 Function Air Fryer Oven is the clear winner. It cooks evenly, offers the most versatility, and feels built to last. If counter space is tight, the Oster Compact Air Fryer Toaster Oven is a capable backup that won’t dominate your kitchen. And if you’re nursing an older Oster back to health, the Toaster Oven Replacement Trays are a cost-effective fix — just measure your existing tray first. Skip the compact model if even toasting is your top priority; the 10-function oven handles that far better.
Frequently Asked Questions
Can I use replacement trays from a newer Oster model in an old Oster toaster oven?
It depends on the year. Oster changed tray dimensions several times. Measure your existing tray’s length and width before ordering. The carbon steel set we tested fit a 2018 model perfectly but was too long for a 2020 compact model. Check the product listing for compatible model numbers or measure your current tray.
What’s the best way to clean an Oster toaster oven older model?
Unplug the oven and remove the crumb tray. Wipe the interior with a damp cloth and mild dish soap — avoid abrasive sponges that scratch the non-stick coating. For stubborn grease on the heating elements, use a dry pastry brush to gently dislodge debris. Never spray water directly into the oven; it can damage the electrical components.
Why does my old Oster toaster oven toast unevenly?
Uneven toasting is usually caused by crumb buildup around the heating elements or a worn-out door seal. Vacuum the interior with a brush attachment, and check the door gasket for gaps. If the seal is loose, heat escapes from one side. Replacing the seal or using a pizza stone to stabilize temperature often fixes the issue.
