Our top pick: Ninja Double Stack XL 12-in-1 Double Oven.
How each alternative compares
Instant Pot 6-Slice 10-in-1 Air Fryer Toaster Oven
The Instant Pot 6-Slice model sacrifices dual-zone cooking for a significantly smaller footprint. At 17.4 pounds, it weighs nearly half as much as the Ninja Double Stack XL, making it easier to store. Its dimensions are 14.6 inches wide and 9.92 inches high, fitting comfortably on tighter counters. You get 10 cooking functions, including air frying and dehydrating, but the single chamber means you cannot cook two distinct meals simultaneously. This unit is best for small households or single occupants who prioritize speed and compact storage over large capacity or simultaneous multi-dish preparation.
Ninja FlexDoor Double Oven
The Ninja FlexDoor Double Oven offers a nearly identical footprint to the Double Stack XL, measuring 18.6 inches long and 16.4 inches wide. It weighs slightly less at 29.8 pounds compared to the 31-pound original. While it shares the dual-chamber design for simultaneous cooking, it provides 10 functions rather than 12. You lose specific programs like Whole Roast and Air Roast found in the premium model. This alternative is suitable for buyers who want the dual-zone capability and large capacity but prefer a lower price point or simpler feature set without sacrificing the ability to keep flavors separate.
Ninja Double Stack XL Oven with Thermometer
The Ninja Double Stack XL Oven with Thermometer is a premium variant of the original, maintaining the same 18.6-inch length and 31.3-pound weight. It retains all 12 cooking functions, including Air Fry, Bake, and Broil. The primary difference is the inclusion of an internal thermometer for more precise temperature monitoring during cooking. This model is ideal for users who already like the dual-zone FlexDoor design and SMART FINISH technology but want added precision for sensitive recipes. It offers the same capacity for six slices of bread or a 4.5-pound chicken without any reduction in versatility.
Gourmia 12-Inch Countertop Electric Pizza Oven
The Gourmia 12-Inch Countertop Electric Pizza Oven focuses exclusively on pizza making rather than general versatility. It measures 21 inches wide and 17.5 inches long, making it wider than the Ninja Double Stack XL. It weighs 28.5 pounds and offers only three functions: Air Fry, Bake, and Broil. You give up the dual-chamber design and most cooking programs to gain specialized high-heat performance for crust texture. This oven is best for dedicated home pizza makers who value cooking speed and specific results over the ability to prepare multiple diverse meals simultaneously.
Ninja 12-in-1 Double Countertop Oven
The Ninja 12-in-1 Double Countertop Oven matches the original in capacity and dual-zone functionality but differs in physical dimensions. It measures 18.5 inches long and 13.4 inches wide, with a height of 16.5 inches, making it taller than the Double Stack XL. It weighs 31 pounds and includes six functions: Air Fry, Convection, Bake, Toast, and Roast. You lose specific programs like Dehydrate, Pizza, and Whole Roast. This model is suitable for households that need simultaneous cooking zones but have limited counter depth or prefer a taller, narrower footprint for their kitchen layout.
Tovala Smart Oven Pro 6-in-1 Steam Oven
The Tovala Smart Oven Pro 6-in-1 Steam Oven replaces dual chambers with a single compartment focused on steam and smart features. It is smaller, measuring 12.3 inches long and 18.5 inches wide, and weighs only 22 pounds. It offers six functions including Steam, Air Fry, and Convection, but lacks the dual-zone capability entirely. The key difference is app-controlled automation for cooking cycles. This oven is best for users who prioritize smartphone integration and steam cooking over the ability to cook two separate meals at once. It suits small kitchens where automated convenience is valued more than simultaneous multi-dish preparation.
