Standard air fryers deliver a decent crunch, but they often strip moisture from meats and leave vegetables dry. The real breakthrough comes from adding steam to the equation — a dedicated water source that injects humidity during the cooking cycle. This approach locks in juices for proteins while maintaining the crispy Maillard reaction on the exterior, and it opens up entire cooking modes like steam-baking and rapid steam that a standard convection fryer simply cannot perform.

I’m Min — the co-founder and writer behind Gadgets Feed. I’ve analyzed hundreds of product listings, cross-referenced real owner reviews, and compared technical specs to isolate the models that actually deliver on their steam-function promise without gimmicks or reliability issues.

After comparing capacity, wattage, steam tank size, cooking presets, and cleaning systems across dozens of models, I’ve narrowed the field to the seven machines that genuinely earn the title of best air fryer with steam function for different kitchen needs and budgets in 2025.

How To Choose The Best Air Fryer With Steam Function

Choosing a steam-capable air fryer is different from picking a standard convection oven. The steam generator, tank capacity, and the ease of switching between dry and wet modes define whether the unit actually performs as advertised. Below are the three most critical factors to evaluate before buying.

Water Tank Capacity & Refill Frequency

The water tank determines how long you can run steam cycles without interruption. Small tanks around 0.5L to 0.8L are fine for 15-20 minute steam bursts but require refills for longer roasting or multi-course meals. Larger 1.4L tanks (like the one found on the EDENPEER) can sustain extended steam sessions and even handle self-cleaning cycles without needing a mid-cook refill. If you plan to steam vegetables while air-frying a protein, prioritize at least a 1L tank.

Combi Mode vs Dedicated Steam-Only Mode

Some models offer a true “combi” mode that runs both the heating element and the steam generator simultaneously — this gives you juicy interiors with crispy exteriors in a single cycle. Other units force you to choose either steam or air fry, requiring manual switching mid-cook. For the best convenience, look for a model that advertises “steam & crisp,” “combi steam,” or “steam bake” as a single preset rather than two separate functions.

Interior Material and Non-Toxic Construction

Steam creates a hot, humid environment that can degrade lower-quality coatings over time. Models with stainless steel interiors (like the Nuwave Combi) resist corrosion and avoid the PFAS chemicals often found in non-stick baskets. If long-term durability and food safety matter, prioritize units that list stainless steel as the primary interior material rather than coated aluminum or plastic.

In‑Depth Reviews

Top Performer

1. Nuwave Combi Steam Oven

120 Presets16 Quart Capacity

The Nuwave Combi Steam Oven is the most versatile unit in this roundup, offering true combi cooking that runs the heating element and steam generator simultaneously. With a 16-quart stainless steel interior, a temperature range from 50°F to 450°F, and 120 chef-designed presets, this machine covers air frying, steam-baking, sous vide (no bags needed), and even toasting with moisture injection for bakery-quality crusts. The PFAS-free stainless steel construction eliminates concerns about chemical coatings degrading under repeated steam cycles.

Owners consistently praise the steam-bake function for bread and the combi mode for proteins — chicken breasts come out tender rather than dry, and the exterior still develops a golden-brown crisp. The preset system is extensive but takes a few sessions to learn; manual temperature and time adjustments are available for experienced cooks. The water tank is removable and dishwasher-safe, and the steam self-cleaning cycle handles grease buildup without scrubbing. At 21.4 pounds, this unit feels solid and well-constructed on the counter.

The only trade-offs are the preheat time (longer than a standard basket air fryer) and occasional error codes reported at very high temperatures above 375°F in combi mode. For users who want one appliance that replaces a toaster, steamer, air fryer, and sous vide machine, the Nuwave Combi delivers unmatched breadth of function with premium build quality.

Why it’s great

  • True combi steam+air fry mode for juicy interiors and crispy exteriors
  • 120 presets cover everything from toast to sous vide without guesswork
  • Fully stainless steel interior with no PFAS non-stick coatings

Good to know

  • Preheat takes longer than basket-style air fryers
  • Some users report Error 2 above 375°F requiring a cooldown

2. Ninja SF301 Speedi Rapid Cooker & Air Fryer

Speedi Meals in 15 min6 Quart Capacity

The Ninja SF301 takes a different approach to steam integration by combining a sealed Rapid Cooker mode with traditional air frying in a single 6-quart pot. Instead of a separate water tank, you add liquid directly to the cooking pot, which the 1760W heating system converts to steam while simultaneously circulating hot air. This design allows complete one-pot meals — rice or pasta on the bottom, protein and vegetables on the crisper tray above — finished in as little as 15 minutes via the Speedi Meals function.

Real-world feedback from owners highlights how well this unit handles full meal assembly: chicken breasts with pasta and broccoli cook evenly without the bottom burning or the top drying out. The switch between Rapid Cooker mode and Air Fry mode is seamless via the SmartSwitch button, giving you access to 12 total functions including bake, sauté, slow cook, and sous vide. The nonstick pot and crisper tray are dishwasher-safe, and the external dimensions (14.1 x 13.8 x 12.4 inches) fit under most cabinets despite the 6-quart capacity serving up to four people.

Limitations include a maximum temperature of 390°F (lower than some pure air fryers) and the plastic exterior, which doesn’t have the premium feel of stainless steel units. The steam function also requires manual water addition rather than a built-in reservoir, meaning you need to open the lid to add liquid during longer recipes. For households that prioritize speed and one-pot convenience over dedicated steam injection, the Ninja SF301 delivers excellent value.

Why it’s great

  • Complete one-pot meals in 15 minutes with steam and air fry combined
  • 12 cooking functions cover virtually every cooking technique
  • Dishwasher-safe nonstick pot and crisper tray simplify cleanup

Good to know

  • No dedicated water tank — requires manual addition mid-cook
  • Maximum temperature caps at 390°F, lower than convection oven models
Family Sized

3. CIARRA 12-in-1 Countertop Steam Oven Pro (25.4QT)

25.4 Quart Capacity33.8 oz Water Tank

The CIARRA Nosh Oven Pro is the largest unit in this lineup at 25.4 quarts, and it brings a genuinely useful 33.8-ounce water tank that sustains extended steam sessions without mid-cook refills. The dropdown door design and polished stainless steel interior give it the look and feel of a full-size wall oven, but it fits on a countertop and operates on standard 120V power. With 11 cooking modes including rapid steam, steam convection, air fry, dehydrate, ferment, and sterilize, this machine replaces a steamer, toaster, dehydrator, and air fryer in one footprint.

Owner reports consistently praise the steam-baking results — bread develops crispy crusts with soft interiors, and whole chickens cook through evenly without drying. The 12-hour programmable timer is convenient for overnight fermenting or slow roasting, and the self-clean steam cycle loosens grease effectively. The combination of touch and knob controls is straightforward, though some users note that the dials are less intuitive than full touchscreen interfaces. The cream/white finish adds a retro aesthetic that stands out against typical black appliances.

The main compromises are weight and counter space — at 17 inches tall and 16 inches wide, this unit demands commitment. A few customers also reported that the exterior is carbon steel with a coating rather than solid stainless steel, so check the product listing closely if material purity matters to you. For large families or frequent entertainers who need maximum capacity with genuine steam functionality, the CIARRA 25.4QT offers outstanding versatility.

Why it’s great

  • Largest capacity in the category at 25.4 quarts with a big 33.8 oz water tank
  • Steam convection mode locks in moisture while circulating hot air for even browning
  • Self-cleaning steam cycle and dishwasher-safe accessories minimize maintenance

Good to know

  • Exterior is coated carbon steel, not full stainless steel
  • Dials and buttons can feel less responsive than modern touch controls
Precision Steam

4. Nuwave PFAS-Free Steam Oven & Air Fryer

10-90% Moisture Control120 Presets

This Nuwave variant is identical in chassis size (16 quarts) to the Combi model above but comes with a slightly different focus — it offers adjustable moisture control from 10% to 90%, giving you fine-grained control over how much steam is injected during any cooking cycle. The 120 one-touch presets include specialized modes for sous vide (no bags required), toast with steam, and X-Crispy air frying that delivers the texture of deep frying with significantly less oil. The entire interior, including the included air fry basket, tray, and cooking rack, is PFAS-free stainless steel.

Real-world testing from owners confirms that the moisture control dial makes a tangible difference for reheating leftovers — pizza crusts come out crispy rather than soggy, and previously refrigerated bread restores its just-baked texture. The steam infusion function for meats is particularly effective: chicken thighs cooked with 50% moisture stay tender while developing a brown, crackling skin. The preheat time is faster than the larger CIARRA models, reaching 350°F in roughly 4 minutes. The dropdown door includes a viewing window and internal light so you can monitor progress without opening the chamber.

On the downside, some users have reported error codes when running the steam function for more than 3 consecutive minutes, though this seems inconsistent across units. The 21.4-pound weight is identical to the Combi model and requires sturdy counter support. If precise humidity adjustment matters for your cooking style (especially for bread baking and reheating), this Nuwave variant gives you control that most competitors don’t offer at this price point.

Why it’s great

  • Adjustable 10-90% moisture control for precise steam injection
  • All stainless steel interior and accessories, PFAS-free construction
  • 120 presets with rapid preheat and X-Crispy mode for low-oil frying

Good to know

  • Steam function may error on some units beyond 3-minute cycles
  • Heavy 21.4-pound footprint requires dedicated counter space
Self Cleaning

5. EDENPEER Steam Air Fryer (7.5QT)

1.4L Pure SteamerSelf-Clean Mode

The EDENPEER is the only model in this group that includes a dedicated 1.4L water tank specifically for pure steam cooking, separate from its air frying function. This matters because it allows you to steam vegetables, fish, or rice independently without combining modes — useful for preserving nutrients in delicate ingredients. The 7.5-quart basket is large enough for a whole chicken or a batch of 20 wings, and the 1700W 360° air circulation system delivers crisp results with up to 87% less oil than deep frying.

Customer feedback consistently highlights the self-cleaning steam cycle as a standout feature — it loosens grease and baked-on residue in 30 minutes without scrubbing. The whisper-quiet noise reduction technology is also frequently mentioned; this unit runs noticeably quieter than most air fryers in this class. The 12-in-1 presets cover everything from steak and fries to dehydration, and the large transparent window with internal light lets you monitor cooking without losing heat. The stainless steel inner material resists corrosion better than coated alternatives.

The primary limitation is the control interface — some users find the touch panel less responsive than physical buttons, and the hand control method takes practice to navigate efficiently. At 16.3 pounds and 15.23 inches tall, it’s slightly bulkier than basket-style fryers but still fits under standard cabinets. For home cooks who want a dedicated pure steam function alongside air frying, plus the convenience of automated self-cleaning, the EDENPEER delivers strong mid-range value.

Why it’s great

  • Dedicated 1.4L pure steamer tank for separate steam-only cooking
  • One-touch steam self-cleaning cycle handles grease in 30 minutes
  • Whisper-quiet operation and large viewing window

Good to know

  • Touch controls can feel less responsive than physical buttons
  • Bulkier footprint than comparable 7-quart basket air fryers
Compact Steam

6. CIARRA 8-in-1 Steam Oven Countertop (13QT)

13 Quart Capacity430°F Max Temp

The CIARRA 8-in-1 is a compact 13-quart steam oven designed for singles, couples, or small kitchens where counter space is at a premium. Despite its smaller footprint (13 x 12.5 x 14 inches), it includes genuine steam injection via a built-in water tank, supporting modes like Rapid Steam, Steam Bake, Air Fry, and even Ferment for bread making. The 430°F maximum temperature is higher than many competitors and preheats 75% faster than traditional ovens, reaching cooking temp in roughly 3-4 minutes.

Owner reports highlight how well this unit handles eggs (16 minutes for perfectly peelable hard-boiled eggs), rice, and small batches of chicken wings. The 360° convection air frying ensures even browning across the 13-quart chamber, and the included air fry basket, baking pan, oven rack, and oven mitts provide everything needed to start cooking immediately. The self-cleaning steam function is effective for daily maintenance, and the unit operates quietly compared to full-size countertop ovens.

The biggest drawbacks are the interface — the dial and button layout is less intuitive than touchscreen models, and there is no memory to recall the last time/temperature setting (annoying for daily toast users). The exterior material was also a point of confusion: the listing claims stainless steel, but several customers report the outer body is actually coated metal. For small households that want true steam functionality in a compact form factor, the CIARRA 8-in-1 offers good performance at a reasonable size.

Why it’s great

  • Compact 13-quart size fits small counters with genuine steam injection
  • 430°F max temperature and rapid preheat outperform many larger ovens
  • Self-cleaning steam function and included accessory kit

Good to know

  • Non-intuitive dial controls lack memory for last-used settings
  • Exterior material may be coated metal rather than full stainless steel
Budget Friendly

7. NutriChef 6 Liter Electric Air Fryer & Food Steamer

6 Liter Capacity12 Preset Programs

The NutriChef 6L is the most accessible entry point into steam-function air frying, offering 12 preset programs including a dedicated steaming option alongside standard air fry, chicken, fries, and dehydrate modes. The 1400W heating element reaches up to 400°F and uses 360° hot air circulation for even cooking with minimal oil. The transparent window and interior light let you monitor progress without opening the basket, and the nonstick removable basket is dishwasher-safe for easy cleanup.

Owners appreciate how simple this unit is to operate — the touchscreen interface is straightforward, and the presets produce consistent results for frozen foods, chicken, and vegetables. The compact dimensions (14.05 x 10.51 x 13.97 inches) fit under most cabinets, and the 6-liter capacity comfortably serves 1-2 people with room for small batches of sides. The auto-shutoff and overheat protection add safety, and the cool-touch handle prevents burns during operation.

The trade-offs at this price point are noticeable: the steam function is basic compared to dedicated steamer tanks, and the 6-liter capacity is small for families (multiple batches required for larger meals). Build quality is adequate rather than premium, and the plastic components don’t match the durability of stainless steel interiors. For budget-conscious buyers who want to experiment with steam-infused air frying without a large investment, the NutriChef provides a functional starting point.

Why it’s great

  • Entry-level price point with 12 presets including steam function
  • Transparent window and interior light for monitoring without opening
  • Dishwasher-safe nonstick basket with auto-shutoff safety features

Good to know

  • Steam function is basic without a dedicated water tank
  • 6-liter capacity is best suited for 1-2 people, not families

FAQ

Can I use an air fryer with steam function to steam vegetables without air frying?
Yes, but it depends on the model. Units like the EDENPEER with a dedicated pure steamer mode allow you to steam vegetables independently without running the convection fan. Models that only offer combi modes require you to set zero or very low fan speed (if available) to achieve pure steaming. Check the preset list for a dedicated “Steam” or “Rapid Steam” mode rather than assuming the unit can do steam-only cooking.
How do I clean the water tank and prevent mineral buildup?
Most removable water tanks are dishwasher-safe on the top rack. For models with integrated tanks, run a descaling cycle with a 50/50 white vinegar and water solution every 4-6 weeks depending on your tap water hardness. Some units like the EDENPEER include a self-cleaning steam cycle that automatically flushes the system. Always empty the tank between uses to prevent mold or bacterial growth in the reservoir.
Does adding steam reduce the crispiness of air-fried food?
Only if the steam is injected too early or at too high a volume. In proper combi mode (steam + air fry simultaneously), manufacturers carefully balance humidity to keep the exterior crisp while the interior stays moist. The Nuwave and CIARRA models use precise moisture control to maintain crunch. The risk of sogginess comes from post-cook steam condensation — always remove food promptly after the cycle ends and avoid stacking items that trap steam between layers.
What size water tank is sufficient for a whole chicken?
For a 4-5 pound whole chicken cooked in combi mode at 375°F for 45-50 minutes, you need at least a 1.0L water tank. Smaller 0.5-0.8L tanks will run dry before the chicken is fully cooked, requiring you to open the door and refill mid-cycle, which releases heat and extends cook time. The 1.4L tank on the EDENPEER or the 33.8 oz tank on the CIARRA 25.4QT both provide enough water for a full chicken without interruption.

Final Thoughts: The Verdict

For most users, the best air fryer with steam function winner is the Nuwave Combi Steam Oven because it combines true simultaneous combi cooking, 120 presets, and a fully stainless steel PFAS-free interior in a versatile 16-quart form factor. If you want the fastest one-pot meal assembly with steam integration, grab the Ninja SF301 Speedi Rapid Cooker. And for large families needing maximum capacity with a generous water tank, nothing beats the CIARRA 25.4QT Nosh Oven Pro.
