Choosing a countertop oven that replaces a toaster, dehydrator, rotisserie, and oven is the goal, but the sheer number of cooking modes, basket shapes, and wattage claims makes separating the true workhorses from the gimmicks difficult. A proper multi-function air fryer must do more than just blow hot air—it needs to handle a full chicken, dehydrate jerky, reheat leftovers without turning them soggy, and still fit under your cabinets.
I’m Mohammad Maruf — the founder and writer behind AirfryerBite. I’ve spent the last 15 years analyzing the technical shifts from single-function fryers to hybrid ovens, comparing motor wattage, temperature ceilings, and basket materials to find which designs actually deliver across every cooking mode without burning out.
After comparing seven contenders spanning compact 6.5-quart baskets and massive 28-quart dual-zone ovens, I’ve identified the models that earn their counter space. This guide breaks down the best multi-function air fryer choices by real-world performance, not just spec sheet fluff.
How To Choose The Best Multi-Function Air Fryer
A multi-function air fryer is not just an air fryer with extra buttons — it’s a countertop oven replacement. You need to verify that each cooking mode actually works well, not just that the preset exists. These four factors make or break the experience.
Capacity versus internal footprint
A 14-quart model and a 20-quart model both claim “family size,” but the 20-quart unit often includes multiple racks or a rotisserie spit that changes how food fits. Measure your counter depth and height—some french-door models need 16 inches of clearance to open fully. Also check whether the basket is one deep drawer or a multi-rack oven: the latter lets you cook two different items simultaneously if the unit has dual zones.
Temperature range and heat-up speed
Standard air fryers cap at 400°F, but several models now hit 450°F or even 500°F. The higher ceiling matters for extra-crispy wings or frozen foods that need a fast sear. 1800-watt units generally preheat faster than 1500-watt units, and a DC motor (like in some premium models) circulates air more efficiently, cutting cooking time by 40%.
Non-toxic build quality
Because these ovens reach high heat and touch your food directly, coating safety is a top consideration. Look for “PFAS-free,” “PFOA-free,” and “BPA-free” on the cooking surfaces and included accessories. Stainless steel interiors resist chipping over time better than painted metal, and glass doors with interior lights let you check doneness without losing heat.
Preset modes versus manual control
Having 12 presets is useless if only four actually produce good results. The best units allow you to override temperature and time in every mode. Features like a dedicated “Frozen” program (that defrosts first then crisps) or a “Hi-Fry” boost for the final minutes add real versatility—these are the functions that separate a genuinely useful oven from a gimmick.

In‑Depth Reviews
1. Ninja XL Air Fryer with MaxCrisp (AF181)
The Ninja AF181 hits the sweet spot for households that want a compact footprint without compromising on crispiness. Its 6.5-quart basket holds 5 pounds of fries or 9 pounds of wings, and the proprietary MaxCrisp technology pushes superheated air to 450°F, delivering a crunch that rivals a deep fryer with 75% less fat. The 6-in-1 preset lineup covers Max Crisp, Air Fry, Air Roast, Bake, Reheat, and Dehydrate — every mode works precisely because the temperature and fan speed are calibrated per function, not just a single timer.
What sets this unit apart from cheaper basket-style fryers is the 1750-watt heater paired with rapid air circulation. You can drop frozen chicken tenders straight into the basket without thawing, and they come out golden in under 12 minutes. The nonstick basket and crisper plate are both dishwasher safe, and the overall dimensions—14.92 inches deep by 11.3 inches wide—fit under standard wall cabinets without the door hitting the upper lip.
The AF181 lacks a viewing window and rotisserie function, so it is not a full oven replacement. But if your primary need is a compact, hyper-efficient fryer that also bakes and dehydrates well, this is the gold standard. The included 20-recipe cookbook helps bridge the gap between simple reheating and creative meal prep.
Why it’s great
- MaxCrisp at 450°F delivers restaurant-quality crunch with minimal oil.
- Compact footprint yet XL basket capacity fits full meals.
- All presets actually work — not just label stickers on the button.
Good to know
- No viewing window — you must open the basket to check doneness.
- No rotisserie spit or dehydrating racks included.
2. Ninja French Door Premier Air Fryer Oven (FO101)
The FO101 redefines the multi-function air fryer by combining a french-door oven format with a dedicated 5-quart air fry basket that slides onto a shelf inside the cavity. That design lets you air fry 5 pounds of fries while simultaneously baking a casserole on the lower rack — something no basket-style unit can do. The 10-in-1 functions include Air Fry, Air Roast, Whole Roast, Bake, Pizza, Broil, Reheat, Dehydrate, Toast, and Bagel, and the 450°F cyclonic air technology ensures even cooking without rotating the basket.
Preheat takes roughly 90 seconds thanks to the powerful heating element design, which is 60% faster than most conventional ovens in its class. All cooking surfaces are PFAS-free, a key differentiator for anyone avoiding nonstick coatings. The one-handed pull doors open simultaneously, giving you full access to both racks without obstruction. The dishwasher-safe air fry basket, sheet pan, broil rack, wire rack, and crumb tray simplify cleanup.
At 22.77 pounds and 16.53 inches wide, this is a substantial countertop appliance that demands dedicated space. It does not include a rotisserie spit, which is a miss given the price tier. But if you want the largest air-frying volume available in a french-door oven and prioritize PFAS-free materials, the FO101 is the benchmark.
Why it’s great
- Dual-rack design lets you air fry and bake simultaneously.
- PFAS-free interior provides peace of mind at high heat.
- 90-second preheat is genuinely fast for a full-size oven.
Good to know
- No rotisserie spit included — separate purchase needed.
- Wide footprint requires 16.5 inches of counter space.
3. Gulck 20 QT 10-in-1 Air Fryer Oven
The Gulck 20-quart model is built for large families who cook volume meals and want an all-in-one appliance without moving into commercial territory. Its 10 preset programs cover fry, bake, roast, dehydrate, reheat, and toast, and the 1800-watt heater with 360° hot air circulation delivers consistent browning across three rack positions. The 20-quart interior (14.6 x 13.4 x 15.4 inches external) easily accommodates a whole chicken on the rotisserie spit while simultaneously crisping vegetables on the upper rack.
What separates this unit from other large ovens is the non-toxic build: all 11 accessories — including the rotating basket, deep basket, drip tray, 3 dehydrating racks, chicken fork, toast rack, and tongs — are PFAS, PFOA, Teflon, and BPA free. The stainless steel drip tray and chromium-plated steel baskets hold up well to repeated high-heat cycles, and the digital touchscreen with a countdown timer makes operation idiot-proof even for first-time users.
The 400°F max temperature is adequate for most recipes, but it cannot reach the 450°F or 500°F zones that some premium fryers offer for ultra-crispy frozen foods. The interior lighting is also absent, which means you must open the door to check progress. Despite these minor compromises, the Gulck delivers enormous capacity with a clean-material guarantee at a mid-range price point.
Why it’s great
- Massive 20-quart capacity with eleven included accessories.
- All cooking surfaces are PFAS and PFOA free.
- Rotisserie kit works smoothly for whole chickens and kebabs.
Good to know
- Max temperature caps at 400°F — no boost mode for extra-crisp finish.
- No interior light makes it hard to monitor browning without opening the door.
4. HotKing Dual-Zone Air Fryer Toaster Oven Combo (28 QT)
The HotKing KATO-28A1 is a 28-quart french-door oven with two independently controlled cooking zones and a SYNC function that times both zones to finish together. This means you can air fry chicken wings at 400°F on the left side while baking a pizza at 375°F on the right side, and both come out hot at the same moment. The 500°F maximum temperature combined with upper and lower heating elements plus dual convection fans delivers the fastest crisping in this lineup—ideal for frozen fries that need an aggressive sear.
The non-toxic build features a stainless steel exterior and PFAS/PFOA/Teflon/BPA-free components. Included accessories are generous: two small air frying baskets, two small air racks, two small baking trays, one large air rack, one large air frying basket, one large baking tray, a rotisserie spit with forks and fetch tool, crumb tray, and a removable divider. Every accessory slides into either zone, and the divider lets you isolate cooking smells or prevent oil splatter between zones.
At 13.7 kilograms (about 30 pounds) and 17.3 inches wide, this is the largest and heaviest unit tested — it needs dedicated counter space and may not fit under low cabinets. The 500°F maximum means you must watch some recipes closely to avoid burning. But for anyone who regularly cooks a main dish and a side simultaneously, the dual-zone SYNC function is a genuine time saver that no single-zone oven can match.
Why it’s great
- Dual-zone SYNC lets you cook two dishes with different temps and finish together.
- 500°F max temperature is the highest in this guide for extra-crispy results.
- Includes a full rotisserie kit plus 11 total accessories.
Good to know
- Heavy build (30 lbs) and wide footprint limit countertop placement options.
- High heat requires careful recipe monitoring to prevent over-browning.
5. Gourmia 14 Qt All-in-One Air Fryer Oven with Rotisserie
The Gourmia 14-quart oven sits in a sweet spot between compact basket units and hulking dual-zone ovens. Its 12 one-touch presets cover everything from frozen fries to rotisserie chicken, and the included rotisserie spit and lift tool make roasting a 4-pound chicken straightforward. The FryForce 360° technology circulates hot air evenly across the stainless steel interior, and the oven mode lets you bake cookies or reheat pizza without flipping the basket around.
The unit delivers 1750 watts of power across a 90°F to 400°F temperature range, which is enough for thorough dehydration and fast roasting. Two air fryer baskets, a drip tray, and a recipe book are included, and all accessories are dishwasher safe. The 15-inch depth and 13.5-inch width let it fit on most standard countertops without overhang, and the black finish blends into most kitchen aesthetics.
There is no interior light or viewing window, which is a drawback for a unit at this price point — you must open the door to check the rotisserie’s progress, which releases heat. The nonstick coating is present only on the included baskets, not on the interior cavity walls, so larger greasy spills may require scrubbing. For families who want a rotisserie oven with reliable presets and are willing to trade some convenience features for capacity, the Gourmia is a solid choice.
Why it’s great
- 12 presets cover air fry, bake, broil, dehydrate, and rotisserie without guesswork.
- Rotisserie kit produces juicy whole chickens with even browning.
- Compact external dimensions fit most standard countertop spaces.
Good to know
- No interior light makes it hard to monitor rotisserie cooking progress.
- Nonstick coating is limited to the baskets — interior walls need manual cleanup.
6. Chefman 14 Qt Multifunctional Air Fryer+ with Rotisserie
The Chefman 14 Qt Multifunctional Air Fryer+ differentiates itself with a Hi-Fry button that boosts the temperature to 450°F during the final two minutes of cooking. This extra burst of heat tightens the crust on anything from pizza to chicken thighs without overcooking the interior. The unit otherwise operates across a 90°F to 400°F range across five functions: Air Fry, Bake, Broil, Reheat, and Dehydrate, plus a dedicated Rotate mode for the included rotisserie spit.
The viewing window and bright interior light let you monitor browning without opening the door — a practical advantage over basket-style fryers. Three wire cooking racks provide flexible shelf positions, so you can stack a baking sheet of vegetables below a rotisserie chicken. All racks are top-rack dishwasher safe, and the fetch tool makes removing the hot rotisserie spit easy. The physical dimensions (13.9 x 13.2 x 14.5 inches) are compact for a 14-quart oven.
At 1700 watts, the Chefman heats slightly slower than the 1750-watt competitors, and the 400°F default means the Hi-Fry button is needed for truly crispy finishing. The included accessories feel adequate but not generous — only three racks and a rotisserie kit. Still, for cooks who frequently want a last-minute crisp boost on breaded items, the Hi-Fry feature is genuinely useful and not found on most other ovens in this tier.
Why it’s great
- Hi-Fry 450°F boost in final two minutes creates a superior crust.
- Viewing window and interior light eliminate guesswork.
- Three adjustable rack positions offer flexible cooking layouts.
Good to know
- 1700W power is lower than the premium 1750W or 1800W units.
- Dehydrate function works but lacks dedicated low-temp presets for jerky.
7. Chefman TurboFry 7-in-1 Air Fryer 9 Qt
The Chefman TurboFry packs a high-tech DC motor that circulates air up to 40% faster than conventional AC-motor fryers, cooking foods quicker while maintaining a 450°F max temperature. The 9-quart basket fits up to 7 people’s worth of fries or wings, and the 7-in-1 functions — Air Fry, Broil, Dehydrate, Convection Bake, Reheat, Keep Warm, and a dedicated Cook Frozen Foods setting — cover the most common multi-function needs without overwhelming the user interface.
The viewing window on the front of the basket lets you glance at the food without pulling the basket out, preserving internal temperature. A Shake Reminder alerts you mid-cycle to toss the basket for even crisping. The nonstick coating on the basket and rack is top-rack dishwasher safe, making cleanup nearly effortless. The cETL certification and 1-year warranty provide baseline reliability assurance.
The 9-quart capacity is smaller than the oven-style units in this guide, so you cannot cook a whole chicken or multiple racks of food simultaneously. The Keep Warm function is capped at 30 minutes, which is shorter than some competitors. But for budget-conscious buyers who want premium features — a DC motor, 450°F cooking, and a frozen-food preset — the Chefman TurboFry delivers impressive performance for its price tier.
Why it’s great
- DC motor cooks up to 40% faster than traditional AC-motor fryers.
- Dedicated frozen food preset defrosts then crisps automatically.
- Viewing window lets you monitor without heat loss.
Good to know
- 9-quart single basket limits cooking volume compared to oven-style units.
- Keep Warm function maxes out at 30 minutes — shorter than some rivals.
