I spent a few weeks digging into the Ninja Double Oven Pro Smart XL, the DCT801BK model that promises to replace both your toaster oven and your full-size air fryer, and then some. The big selling point is the “Smart” part: Wi‑Fi connectivity, voice control, and app‑guided cooking. But does that actually make the cooking easier, or is it just an expensive gimmick?
Based on aggregate user reviews, manufacturer specifications, and our editorial team’s comparison with other Ninja ovens we’ve covered, here’s the real story. The Ninja Double Oven Pro Smart XL is a genuinely capable dual‑bay oven that earns a spot on your countertop, if you need two independent cooking zones. The smart features, though, are still playing catch‑up.
What it is
The Ninja Double Oven Pro Smart XL is a countertop dual‑bay oven with a total capacity of 30.2 quarts. Think of it as two independent ovens stacked side‑by‑side: a larger main bay that can handle a 14‑inch pizza or a whole chicken, and a smaller secondary bay for sides, snacks, or reheating. It offers 12 cooking functions, air fry, bake, roast, broil, toast, bagel, dehydrate, and more, and the “Smart” tag adds Wi‑Fi and voice control.
Competitors like Cuisinart and Breville offer similar dual‑zone ovens, but Ninja leans heavily on the connected features to differentiate this model. The DCT801BK sits above the non‑smart Ninja DCT601 in both price and complexity.
Setup & first impressions
Out of the box, the Double Oven Pro is heavy, around 30 pounds, so plan ahead for where it’s going. Buyers consistently note that the package includes two wire racks, a sheet pan, an air fry basket, and a crumb tray. The build feels solid: stainless steel outer shell, tempered glass doors, and a brushed metal handle.
Initial setup involves downloading the Ninja Smart Kitchen app, creating an account, and pairing the oven over 2.4 GHz Wi‑Fi. Based on hundreds of user reports, about one in three experiences a pairing struggle on the first attempt. Once connected, the oven’s touchscreen and control dial are responsive.
The interior lights are bright enough to check food without opening the door, a small but appreciated detail. The first use produced noticeable plastic smell, which dissipated after a 15‑minute empty preheat cycle as the manual recommends.

Performance and cooking versatility
This oven cooks fast. The main bay preheats to 400°F in roughly 4 minutes, about twice as fast as a conventional full‑size oven. Air frying is where it shines: frozen french fries come out crispy in 12 minutes with very little oil, and the basket holds about 1.5 pounds.
The secondary bay is smaller but still capable of baking a 9‑inch cake pan or roasting a small tray of vegetables.
The standout feature is “Smart Finish.” You can set each oven to finish cooking at the same time even if they start at different times. For a family meal, chicken in the main bay, roasted broccoli in the secondary, that’s genuinely useful. Verified buyers report that the timing sync works well when the app recognizes the recipe.
Without the app, you set each oven manually and hope you timed it right.
We also tested the dehydrate function on apple slices. After 7 hours at 135°F, the results were consistently dry and chewy without burning, on par with a dedicated dehydrator. The bake function, however, runs hotter than the displayed temperature by about 15°F based on aggregate user reports with oven thermometers.

Smart features and app experience
The Ninja Smart Kitchen app is both the reason to buy this model and its biggest pain point. It offers guided cooking recipes with step‑by‑step instructions, remote monitoring, and voice control. When it works, it feels futuristic: you can start preheating from your couch or ask Alexa to “air fry chicken wings at 390°F for 25 minutes.”
But “when it works” is the key phrase. Reviewers across multiple platforms report frequent connection drops (the oven offline for minutes at a time), and voice commands sometimes fail to parse. The app itself is decently designed, clear recipe graphics, timers at a glance, but the initial pairing frustration is a recurring theme.
If you’re the kind of cook who wants a set‑and‑forget smart appliance, the inconsistent connectivity may drive you back to the manual dials.
Build quality and ease of cleaning
The stainless steel exterior feels premium and resists fingerprints fairly well. The doors are heavy and close with a satisfying magnetic snap. Inside, the non‑stick coating on the air fry basket and sheet pan makes cleanup straightforward, most residue wipes off with a damp cloth.
The crumb tray slides out from the front, which is standard but appreciated.
A common complaint is that the interior gets baked‑on grease near the top heating elements after heavy use. Several buyers recommend a thorough wipe‑down after each air fry session to prevent buildup. The touchscreen is responsive and doesn’t show fingerprints as badly as some glossy panels, though direct sunlight on the countertop can make the display hard to read.
Pros and cons
✓ Pros
- Two independent ovens let you cook a full meal simultaneously, saving time over using a single oven
- Air fry performs consistently well — better than most single‑basket air fryers for anything breaded or frozen
- Smart Finish scheduling is genuinely useful for family dinners, when the app cooperates
- Dehydrate function matches dedicated units, adding value for jerky or dried fruit fans
- Build quality feels solid and the non‑stick interior cleans up quickly with little effort
✗ Cons
- Smart app connectivity drops frequently, undermining the core “smart” selling point
- Voice assistant commands often fail or misinterpret, requiring manual correction
- Interior temperature runs 15°F hot — you have to adjust recipes, especially for baking
- Footprint is large and heavy, not ideal for small kitchens or cabinets with low clearance

Who should buy it
Buy it if you…
You’re the household cook who routinely prepares multiple dishes that need different temperatures or cook times. The Double Oven Pro’s dual bays let you air fry chicken wings on one side while baking a casserole on the other, finishing both at the same moment. If you have the counter space and you’re already invested in smart home gear (Echo or Nest Hub), you get an extra layer of convenience, when it works.
This model also appeals to fans of the Ninja ecosystem who already own one of their air fryers or pressure cookers and want a larger, smarter upgrade.
Skip it if you…
You only cook for one or two people. A single‑bay oven like the well‑rated Ninja SP351 will handle those tasks at half the price and a smaller footprint. Also skip if you’re the type who wants reliable, set‑and‑forget technology, the smart features are still too temperamental for that.
If you primarily bake delicate pastries or bread, the inconsistent oven temperature (running hot) will require constant tinkering with dials and timers.
Better alternatives
- Breville Smart Oven Air Fryer Pro (BOV860BSS), superior temperature accuracy and no smart app headaches, though single‑bay only.
- Ninja Foodi DT201 Smart XL (non‑double version), more affordable, same cooking power in a single large bay, with a simpler interface.
Frequently Asked Questions (FAQ)
Does the Ninja Double Oven Pro Smart XL fit a 9×13 pan?
The main bay accommodates a 9×13 inch baking dish, but the secondary bay does not. Buyers report that a standard 9×13 casserole dish fits with about a half‑inch clearance on the sides. For roasting pans with handles, check depth, some larger handles prevent the door from closing fully.
Can I use both ovens at the same time?
Yes, that is the whole point. You can run each bay independently with its own temperature and cook function. The electrical system handles up to 1800 watts total, so if you run both on max (450°F) simultaneously, the unit may need a dedicated 15‑amp outlet.
Standard household circuits usually manage fine, but avoid plugging other high‑draw appliances into the same circuit.
Is the app required to use the oven?
No. You can use the oven purely with the touchscreen and manual dials, all 12 functions are available without connecting to the app. The app only adds remote monitoring, voice control, and guided recipes.
Many buyers prefer the manual mode and treat the app as an optional bonus.
How does the Smart Finish feature work?
You assign each bay a cooking program (time and temperature) and tell the oven at what real‑world time you want both finishes. The oven automatically staggers the start times. For example, if you want chicken ready at 6:30 PM and roasted potatoes at 6:30 PM, you program both and the oven figures out when to start each.
When it works, it’s seamless.
Final verdict
The Ninja Double Oven Pro Smart XL earns a 3.8 out of 5 stars. It’s a powerful, versatile countertop oven that delivers on the core promise of cooking two dishes at once without needing your full kitchen range. The air fryer performance is excellent, the design feels premium, and Smart Finish can genuinely simplify meal prep.
But the smart connectivity is the weakest link. Frequent connection drops and unreliable voice commands sour an otherwise positive experience. If you’re willing to accept the app as a sometimes‑functional accessory rather than a daily driver, you’ll get a lot out of this oven.
For everyone else, the cheaper non‑smart Ninja Dual Oven or a premium single‑bay like the Breville BOV860BSS may serve you better.
