Compare Toaster Ovens
BLACK+DECKER 4-Slice Toaster Oven scores higher on safety - here's why.
The most important dimensions, side by side.
The oven's interior cavity has a zinc coating that independent safety researchers have flagged for potential lead contamination risk when used at high temperatures. This is worth knowing if you regularly bake or broil — the walls are what your food's steam and drippings interact with most. We're working from an independent reviewer's physical assessment here, not the brand's own disclosure.
Non-stick interior with no disclosure of coating type. Without transparency on whether this is PTFE or ceramic, we cannot rule out toxic off-gassing at broil temperatures.
BLACK+DECKER doesn't make any chemical-safety claims for this oven — no PFAS-free statement, no independent testing, nothing. The stainless steel accessories are inherently free of these chemicals by material composition, but the brand provides no formal assurance for any surface. For families who want that confirmation in writing, it simply isn't available here.
No PFAS assurance of any kind has been made by the brand for this product.
The baking tray where your food sits appears to be stainless steel — a non-reactive, coating-free surface that's genuinely good for food contact. The one gap is that the brand hasn't published which grade of stainless it is, so we can't confirm it's food-grade certified stainless. We're working from an independent reviewer's hands-on assessment.
PTFE-coated tray in direct contact with food. PTFE degrades at oven temperatures, releasing fluorinated compounds onto food surfaces — the highest-risk tray material in the category.
The interior fits a 9-inch pizza, four slices of toast, or a small casserole — plenty of room for a couple or a small family cooking light meals. It won't fit a whole chicken, but for everyday toaster oven use that's not a realistic ask at this size. Note that this measurement comes from an independent reviewer's conversion, not a spec directly from the brand.
You get four straightforward cooking modes: toast, bake, broil, and keep warm. That covers the basics for most households. There's no dedicated reheat mode, no air fry, and no bagel or pizza setting — so if you're looking for a versatile multi-cooker, newer competitors offer more.
Five hundred degrees via Dual Heat Technology -- top and bottom elements firing together with rapid cyclonic air. This is the threshold for pizza stone use, high-heat searing, and maximum broiling. Only the Our Place matches this temperature in the comparison set.
Rapid cyclonic air technology is Ninja's version of convection, and it's aggressive -- food crisps faster and more evenly than standard convection. The air fry function is one of 13 presets, and it works well.
The Smart Thermometer monitors food temperature via a probe -- useful for meat doneness, but it measures the food, not the oven. The oven cavity temperature accuracy itself is unverified by any independent lab. Ninja claims precision, but no one outside the company has confirmed it.
The crumb tray slides out completely for easy cleaning — a simple feature that matters a lot for everyday hygiene and fire safety. Multiple reviewers confirmed it works as expected.
Removable crumb tray with replacement parts available from Ninja. The flip-up storage design is a practical bonus for smaller kitchens -- fold it up against the backsplash when not in use.
Digital display with dial controls and 13 presets. Sear Crisp, Griddle, and separate Frozen Pizza / Fresh Pizza modes are functions most competitors don't offer. The interface is intuitive -- select a function, the oven suggests settings, you adjust and go.
At roughly $47, this is one of the most affordable toaster ovens on the market. But the low overall safety score means you're not getting strong chemical-safety assurance for the money — a slightly higher investment could buy an oven from a brand that's more upfront about what's inside.
At $270, the Ninja is $20 more than the Instant Omni Plus (91/100) and scores 53/100. The performance features are genuinely strong -- Dual Heat, 13 presets, Smart Thermometer -- but the unresolved safety questions make the price hard to justify when safer alternatives cost less. SlickDeals has tracked this oven at $190 on sale, which shifts the value equation if you can wait.
Everything you need to make the call - who each one is for, and who should skip it.
Go for it if you...
You need a compact toaster oven under $47 and mainly use it for toasting bread or reheating small portions.
You plan to line the tray with parchment paper and don't need the oven for high-heat broiling or roasting.
You want a simple, dial-control oven with no digital features to learn or maintain.
Counter space is tight and you need the smallest footprint that still fits a 9-inch pizza.
You want maximum cooking versatility -- 13 presets including Sear Crisp, Griddle, and Frozen Pizza modes that no other oven here offers.
You need 500°F for pizza stone use or high-heat searing and want Dual Heat Technology for faster preheating.
The Smart Thermometer for internal food temperature monitoring is important to your cooking style.
You've accepted the unspecified coating and lack of certification as known unknowns.
The main thing to know
The oven's interior cavity has a zinc coating that independent safety researchers have flagged for potential lead contamination at high temperatures. BLACK+DECKER makes no chemical-safety claims for any surface.
The Ninja SP351 is a powerhouse for cooking -- 500°F Dual Heat Technology, 13 presets, and a Smart Thermometer for internal food temperature monitoring. But the oven interior is labeled 'non-stick' without any disclosure of whether that's PTFE or ceramic. At 500°F max temperature, if the coating is PTFE, this oven heats to the exact temperature where PTFE begins to degrade. No UL/ETL certification was found either.
Skip this if you...
Material safety across every surface matters to your family — the zinc-coated interior is an unresolved concern and the brand offers no chemical-safety assurances.
You want a brand that's transparent about what its products are made of — BLACK+DECKER doesn't publish interior material specs.
You need more than basic toast, bake, and broil — there's no reheat mode, air fry, or modern cooking presets.
You need to know what coating touches your food -- Ninja won't disclose whether the interior is PTFE or ceramic. At 500°F, this matters more than on any other oven in the comparison.
You want independently certified electrical safety -- no UL or ETL mark was found for the SP351.
Safety transparency is a priority -- both the interior coating and safety certification are unresolved. The Instant Omni Plus at $20 less offers a porcelain-enamel interior and UL Listed certification.
Neither of these quite what you're looking for?
