An all-in-one air fryer is the only countertop appliance that can replace a toaster oven, a rotisserie, a dehydrator, a broiler, and a standard air fryer in a single footprint. The challenge is finding one that actually does each job well without sacrificing crunch, heat distribution, or capacity.
I’m Emma — the founder and writer behind Baby Bangs. I’ve spent months comparing wattage, temperature ranges, cooking presets, and real-world performance data across dozens of models to understand which units deliver consistent results across every function.
Whether you need to batch-cook for a large family or keep your meal prep non-toxic, the right all in one air fryer can simplify your kitchen without compromising on texture or versatility.
How To Choose The Best All In One Air Fryer
Choosing an all-in-one air fryer means weighing capacity, power, and material safety against the specific ways you cook. A 6-quart machine that handles a single chicken is fine for two people, but a 20-quart oven with multiple racks changes your meal prep entirely.
Capacity and cooking volume
Capacity is the first gate. A 10-quart dual-basket model lets you cook a main and a side simultaneously, while a 14-to-21-quart oven-style unit can handle a whole chicken, a full pizza, or multiple trays of dehydrated fruit. Smaller 6-to-10-quart models fit tight countertops and serve one to four people. Match the capacity to your typical batch size, not the rare party scenario.
Heating power and circulation
Wattage directly affects preheat time and cooking speed. Most models sit between 1,500 and 1,800 watts. Higher wattage paired with a high-speed fan — often marketed as 360° or rapid air circulation — produces more even browning and crispier exteriors. Look for units that advertise a consistent temperature across multiple racks or zones rather than a single hot spot.
Material safety and non-toxic construction
Non-stick coatings are common, but some contain PFAS, PFOA, or PTFE — substances some users prefer to avoid. Borosilicate glass and stainless steel interiors are the safest bets for zero chemical leaching. Check the “Included Components” list for the inner material, and look for explicit “PFAS-free” or “BPA-free” labels if food contact safety is a priority.

In‑Depth Reviews
1. Ninja Crispi Pro 6-in-1 Glass Air Fryer (AS101DG)
The Ninja Crispi Pro shifts the category forward with borosilicate glass containers — no forever chemicals on any food-contact surface. The 6-quart and 2.5-quart glassware handles thermal shock, so you can pull a container from the freezer and go straight into the 450°F cooking cycle without thawing or extra dishes. The 1800-watt base powers Max Crisp, Air Fry, Bake/Proof, Roast, Recrisp, and Dehydrate modes, and the modular base adjusts to fit multiple container sizes.
Real users consistently report faster heating, more even results, and the ability to watch food cook through the glass walls. The snap-lock storage lids convert each glass container into a meal-prep vessel, reducing plastic waste in the fridge. The system feeds up to ten people with the larger bowl, yet the footprint remains compact enough for small countertops.
Downsides include the non-removable base — the glass bowls do not nest for storage — and the premium cost that puts it above nearly every other option here. The clear-glass design also requires careful handling to avoid scratches on granite or marble surfaces.
Why it’s great
- 100% PFAS, PTFE, and BPA-free borosilicate glass
- Thermal shock resistant — freezer to air fryer without cracking
- Snap-lock lids for cooking, storing, and meal prepping in one vessel
- 1800-watt power delivers even crisping across the 6-qt container
Good to know
- Bowls do not nest for space-saving storage
- Modular base is not removable for cleaning
- Requires careful handling to avoid scratching delicate surfaces
2. Nuwave Bravo Pro Air Fryer Toaster Oven Combo
The Nuwave Bravo Pro brings chef-grade customization with a 50°–450°F range adjustable in 5° increments and three-speed fan control — something few competitors offer. You can dial the top and bottom heater ratio from 0 to 100% during cooking, which matters for thick-crust pizza where you want a crispy bottom and fully melted toppings without burning the top. The 21-quart capacity fits a 12-inch pizza or a 4-pound chicken, and the stainless steel interior keeps food-contact surfaces free of toxic coatings.
User feedback highlights the infrared-like evenness across multiple racks — the unit maintains only a 0–1°F difference between layers, which is rare in convection ovens at this size. The 1800-watt system heats fast and the 2025 improved digital display is brighter and more intuitive than prior versions. Presets cover air fry, roast, bake, reheat, bagel, pizza, toast, broil, waffle, and dehydrate, with on-the-fly customizations.
The dropdown door design is solid, but some users note the lack of an interior light and a memory function for interrupted cycles. The overall depth is 13.5 inches, so check your counter depth before buying.
Why it’s great
- 50°–450°F temperature range in 5° increments
- Adjustable top/bottom heater ratio and fan speed
- Stainless steel interior — no non-stick coatings
- 21-qt capacity fits a 12-inch pizza or 4-lb chicken
Good to know
- No interior light for checking food mid-cycle
- Lacks memory function if power interrupts cooking
- Dropdown door extends the depth needed on counter
3. Ninja Foodi Air Fryer DZ302
The Ninja Foodi DZ302 solves the biggest pain point of single-basket air fryers — you cannot finish a main and a side at the same time. Two independent 5-quart baskets each have their own heating element and fan, and Smart Finish synchronizes the end times so everything is ready together. Match Cook copies settings across both baskets for full 10-quart capacity when you need it. The six cooking programs include air fry, air broil, roast, keep warm, dehydrate, and bake.
Users consistently report that the dual-zone design cuts total cooking time in half versus back-to-back batches. The unit handles up to 8 pounds of chicken wings across both baskets, and the non-stick crisper plates are dishwasher safe. The 450°F maximum temperature delivers good browning on frozen foods without preheating — fries come out crispy in six to eight minutes.
No halfway-cooking notification means you have to check items manually. The inner material is plastic, which matters if you are avoiding plastic food-contact surfaces. The unit is 17.1 inches deep, so verify your counter space can accommodate the footprint.
Why it’s great
- Dual independent baskets with separate temperature and timer controls
- Smart Finish ensures both foods are done at the same moment
- Match Cook replicates settings for full 10-qt capacity meals
- Cooks two 6-lb chickens up to 30% faster than a conventional oven
Good to know
- No audible reminder to shake or flip food mid-cycle
- Inner material is plastic, not stainless steel
- Deep footprint requires 17.1 inches of counter depth
4. Oster 11-Quart Dual Air Fryer Oven
The Oster Dual Air Fryer Oven uses a removable partition to switch between two 5.5-quart independent zones and a single 11-quart oven. This modular approach lets you cook two foods at different temperatures in separate baskets, or remove the divider to fit an entire chicken. The six cooking modes — air fry, turbo crisp, roast, grill, bake, and reheat — cover the essentials without overwhelming you with presets. The unit comes with eight dishwasher-safe accessories including two baskets, two mesh trays, two crumb trays, a large roasting tray, and a basket handle.
Buyers highlight the integrated storage drawer that keeps all accessories together, which is a thoughtful detail for keeping the counter organized. The dual pull-down doors make it easy to check or shake each zone independently. Turbo crisp mode gets favorable reviews for adding an extra layer of browning to frozen items without over-drying the interior.
Some users note that the presets often need extra time added, especially for larger batches of dense foods like chicken thighs or potato wedges. The fan noise is noticeable but not disruptive. The unit is not particularly deep, but the 14.5-inch height means it requires clearance above for proper airflow.
Why it’s great
- Removable partition converts dual 5.5-qt zones into one 11-qt oven
- Integrated storage drawer for all eight accessories
- Two independent pull-down doors for easy food access
- Turbo crisp mode adds extra surface browning
Good to know
- Preset timings may need manual extension for larger loads
- Fan noise is more audible than some competitor models
- Height clearance of 14.5 inches required above unit
5. Gourmia 14 Qt All-in-One Air Fryer Oven with Rotisserie
The Gourmia 14 Qt strikes a strong balance between size, performance, and value. Its 1750-watt FryForce 360° technology circulates hot air evenly around a 14-quart chamber large enough for a full rotisserie chicken or a batch of fries for the whole family. The 12 one-touch presets cover air fry, roast, bake, broil, dehydrate, and rotisserie, and the included rotisserie spit, lift tool, drip tray, and recipe book mean you can roast a whole chicken right out of the box. The stainless steel inner material resists staining and handles dishwasher cleaning well.
Customer reviews consistently praise the double-deck design that effectively replaces a standard oven for most daily cooking tasks. The adjustable shelves allow you to broil sous-vide meat quickly, and the presets produce accurate cook times with minimal trial and error. The unit measures 16 inches tall and 13.5 inches wide, fitting comfortably on most countertops without dominating the space.
The main structural concern is stability — the unit is relatively lightweight at 14.8 pounds, and the door latch tension can cause the oven to tip forward when opened unless you hold the back down. Crumbs also tend to collect between the bottom of the door and the unit body, requiring careful cleaning with a thin brush or vacuum attachment.
Why it’s great
- 14-qt capacity fits a full rotisserie chicken with included spit
- 12 one-touch presets with accurate cook times
- Double-deck design with adjustable shelves for multi-layer cooking
- Stainless steel interior for non-reactive food contact
Good to know
- Tends to tip forward when door is opened unless base is held
- Crumbs accumulate between the door bottom and the unit body
- Not ideal for very small households — 14-qt is best for 3+ people
6. Instant Pot 10QT Air Fryer, 7-in-1
Instant Pot brought the brand’s reliability into the air fryer space with the 10QT 7-in-1, which uses EvenCrisp Technology to achieve browning with 95% less oil than traditional deep frying. The seven functions — air fry, roast, broil, bake, reheat, dehydrate, and rotisserie — are controlled via six one-touch presets, and the large front window lets you check progress without opening the door. The 1500-watt performance is sufficient for the 10-quart capacity, which handles up to six portions per cycle.
User reviews are overwhelmingly positive, with many reporting superior results for steak, fish, burgers, and sweet potato fries versus other cooking methods. The included rotisserie basket, spit, forks, and lift tool expand the unit’s capabilities, and the non-stick drip pan and perforated cooking trays are dishwasher safe for easy cleanup. Safety features include overheat protection and auto-off.
Some users report a persistent chemical smell that does not dissipate after months of use. The presets generally produce good results, but the beeper is quiet enough that the preheat alert can be missed. The 10-quart capacity is a sweet spot for two to four people but may feel tight for larger families.
Why it’s great
- EvenCrisp technology delivers browned results with minimal oil
- Large front window allows visual monitoring without opening the door
- Includes rotisserie basket, spit, and lift tool for whole chickens
- Safety features — overheat protection and auto-off
Good to know
- Some users report a persistent chemical smell after months
- Preheat beeper is very quiet and easy to miss
- 10-qt capacity is best for 2–4 people, not large families
7. Gluck 20 QT 10-in-1 Air Fryer Oven
The Gluck 20 QT is the largest unit in this lineup, offering 20 quarts of cooking volume in an oven-style form factor. Its 1800-watt motor drives 360° hot air circulation for even crisping, and the 10-in-1 preset menu gives one-touch access to air fry, bake, roast, dehydrate, reheat, and toast functions. The accessory bundle is the most generous here — 11 pieces including a rotating basket, deep basket, drip tray, fetch rack, three dehydrating racks, chicken fork, toast rack, tongs, and two oven mitts.
All accessories are dishwasher safe and free from PFAS, PFOA, Teflon, and BPA — a clear advantage if you want non-toxic materials without paying premium pricing. The intuitive LED touch screen and countdown timer make it beginner friendly. User feedback emphasizes the consistent browning across multiple racks and the ability to cook a whole chicken alongside sides in one cycle. The magnetic cooking charts on the body are a practical reference for times and temperatures.
Long-term reliability is a concern — some units fail after several months, though the one-year warranty and responsive customer service appear to handle replacement requests smoothly. At 21.6 pounds, the unit is heavy enough that it will stay put on the counter, but moving it for cleaning requires two hands. The 20-quart size may not fit under standard upper cabinets with a 15.4-inch height.
Why it’s great
- 20-qt capacity handles whole chickens, multiple racks, large batches
- All 11 accessories are dishwasher safe and PFAS/PFOA-free
- Magnetic heating charts stick to the unit for quick reference
- 1800W with 360° hot air for even multi-layer cooking
Good to know
- Some units experience electrical issues after several months
- 21.6-lb weight makes it difficult to reposition for cleaning
- 15.4-inch height may not clear under standard upper cabinets
