Air Fryer Performance: Good but compromised by basket size and lid seal mechanics
Overall Rating: 8.7 / 10
The Duo Crisp solves the appliance clutter problem. If you’re choosing between buying an Instant Pot and an air fryer separately, this delivers both functions in one footprint. But if you already own a pressure cooker, the air fryer lid isn’t compelling enough to justify replacing it. The 5-quart air fryer basket is too small for families, the lid swap between functions adds friction to weeknight cooking, and standalone air fryers outperform it on crisping speed and evenness.
Where It Fits in the Ecosystem
The Duo Crisp sits between the standard Instant Pot Duo (6-quart, $80–100) and dedicated countertop air fryers like the Cosori or Ninja models ($100–130 for 6-quart capacity). It’s designed for people who want both functions but don’t want two separate appliances.
If you already own an Instant Pot and are considering adding air frying: a standalone air fryer gives you better performance and more capacity for roughly the same incremental cost as upgrading to the Duo Crisp.
If you’re starting from zero appliances: the Duo Crisp makes sense as a space-saving solution, especially in small kitchens or RVs.

Build Quality & Construction
The Duo Crisp uses the same stainless steel inner pot and pressure cooking base as the standard Instant Pot Duo. That’s the good news. The pressure cooker component is proven and reliable.
The air fryer lid is where things get interesting. It’s a separate component that swaps on and off. The lid houses a 1500W heating element and a fan that pulls air down through the basket and vents it out the back. The basket itself is a 5-quart nonstick-coated steel insert that sits inside the 8-quart stainless pot.
Here’s what stands out:
- Lid swap mechanism: The air fryer lid clicks into place with a locking handle. It’s secure once locked, but the swap itself takes 8–10 seconds and requires both hands. During testing I found myself planning which function I’d use before I started cooking because mid-recipe lid swaps felt disruptive.
- Basket size mismatch: The 8-quart pressure pot holds the 5-quart air fryer basket with several inches of wasted vertical space. This isn’t a design flaw — it’s a compromise to keep the pressure cooking capacity large while the air fryer basket stays usable. But it means the air fryer never feels as efficient as a purpose-built model.
- Sealing ring storage: The pressure lid requires a sealing ring. When you swap to the air fryer lid, that sealing ring sits exposed on the counter or gets stored separately. After three weeks of testing I’m still annoyed by this. It’s a small thing, but it adds friction.
The controls are straightforward. Digital display, function buttons for each mode, manual time and pressure adjustments. Nothing complicated.
Pressure Cooking Performance
I tested the Duo Crisp against the standard Instant Pot Duo (borrowed from a neighbor) to see if the dual-function design compromised pressure performance. It didn’t.
Rice Test
4 cups jasmine rice, 4 cups water, 3 minutes high pressure, 10-minute natural release. The Duo Crisp brought the pot to pressure in 9 minutes 17 seconds.
Rice came out fluffy, evenly cooked, no scorching on the bottom. This matches the standard Duo’s performance exactly.
Black Bean Test
1 lb dry black beans (no soak), 6 cups water, 30 minutes high pressure, natural release. Time to pressure: 11 minutes 42 seconds.
Beans came out tender with intact skins. No blowouts. Cooking liquid was dark and thick, which is expected. The Duo Crisp held pressure rock-solid — the float valve didn’t drop once during the 30-minute cook.
Chicken Breast Test
4 refrigerated chicken breasts (7 oz each), 1 cup chicken stock, 6 minutes high pressure, 5-minute natural release.
Time to pressure: 8 minutes 3 seconds. Internal temperature at 6 minutes: 163°F (measured immediately after pressure release). Chicken was tender, not rubbery. Stock reduced slightly but didn’t scorch.
Pot Roast Test
3 lb chuck roast, seared on sauté mode first, then pressure cooked with onions, carrots, and beef stock for 60 minutes on high pressure.
Natural release for 15 minutes. The roast came out fork-tender. Searing on sauté mode worked fine but required 4 minutes per side to develop real color — this is slower than stovetop searing in a cast iron skillet, but it’s functional.
Cross-review comparison: The Duo Crisp’s pressure cooking performance is indistinguishable from the standard Duo. If you’re buying this primarily as a pressure cooker, you’re getting the same reliability Instant Pot is known for.
Air Fryer Performance
This is where the Duo Crisp shows its limitations.
Chicken Wing Test
2 lbs chicken wings, tossed in baking powder and salt (standard air fryer prep), cooked at 400°F for 25 minutes with one flip at the 12-minute mark.
The wings came out crispy on the edges but unevenly browned. The top layer crisped well. The bottom layer — the wings touching the basket floor — stayed pale and slightly rubbery. I had to pull the bottom wings out, rearrange them to the top, and run another 6 minutes to get them evenly crisped.
Temperature measurement: I checked the basket temperature with an infrared thermometer during cooking. Center of the basket read 387°F. Outer edge read 362°F. That’s a 25°F variance, which is higher than I’d expect from a dedicated air fryer like a Cosori (which typically shows ≤15°F variance).
In cycle 7 I tried to speed things up by increasing the temp to 425°F. The top wings burned at the 18-minute mark while the bottom wings were still pale. Don’t be me.
Frozen Fries Test
1.5 lbs frozen crinkle-cut fries, 400°F for 18 minutes, shaken at 9 minutes.
The fries came out acceptably crispy on top but soft on the bottom. The 5-quart basket forced me to pile the fries about 1.5 inches deep, which prevented proper air circulation. A 6-quart air fryer would have given me a single layer, which would have crisped more evenly.
I ran this test three times with different fry loads:
- 1 lb fries: Crisped evenly in 16 minutes
- 1.5 lbs fries: Uneven crisping, required mid-cook shake and rearranging
- 2 lbs fries: Bottom layer stayed soft even after 22 minutes
Practical takeaway: The 5-quart basket works for small portions (1–1.5 lbs) but fails at larger volumes.
Brussels Sprouts Test
1 lb Brussels sprouts, halved, tossed in olive oil and salt, 375°F for 14 minutes, shaken at 7 minutes.
The sprouts roasted well. Outer leaves crisped nicely, interiors stayed tender. The lower temperature (375°F vs 400°F) helped with evenness — I didn’t see the same hot-spot issues I saw with the wings.
Temperature variance at 375°F: 19°F between center and edge. Still higher than a dedicated unit, but more manageable.
Chicken Thigh Test
6 skin-on chicken thighs, 380°F for 22 minutes, flipped at 11 minutes.
Skin crisped on the top side but stayed flabby on the underside even after flipping. The thighs closest to the heating element (top center of the basket) browned aggressively, while the outer thighs stayed pale. I ended up pulling the well-browned thighs at 19 minutes and letting the pale ones run another 4 minutes.
Cross-review comparison to standalone air fryers: A 6-quart Cosori or Ninja air fryer crisps more evenly and handles larger batches. The Duo Crisp’s air fryer performance is good enough for small portions but falls short when you’re cooking for more than two people.
Lily’s Lab Note
The Duo Crisp’s air fryer performance isn’t limited by wattage or fan design. It’s limited by geometry.
The 5-quart basket sits inside an 8-quart pot, which leaves 2–3 inches of unused vertical space between the basket floor and the pot bottom. That gap disrupts airflow. The heating element pulls air down through the basket, but instead of venting smoothly out the bottom (like in a dedicated air fryer), the air has to circulate through that dead space before exiting through the rear vent.
This isn’t a fatal flaw. But it explains why the Duo Crisp shows higher temperature variance and uneven crisping compared to purpose-built air fryers. The airflow pattern is compromised by the dual-function design.
I’m not sure this could have been solved without making the unit significantly larger or abandoning the 8-quart pressure cooking capacity. It’s a design trade-off, not incompetence. But it’s a trade-off you should understand before buying.
The air fryer function works. It just works best for small portions and foods that don’t require aggressive edge-to-edge crisping.
Reality Check
The Instant Pot Duo Crisp has mixed feedback across cooking communities. People who use it primarily for pressure cooking appreciate having the air fryer as a bonus feature — even if it’s not best-in-class, it’s useful for reheating leftovers or crisping small batches without firing up a full oven. People who bought it expecting air fryer performance on par with dedicated units are consistently disappointed by the small basket size and uneven browning.
Both perspectives reflect the same underlying truth: the Duo Crisp is a pressure cooker first, air fryer second. If you approach it with that expectation, it delivers. If you expect it to replace a standalone air fryer, you’ll find it limiting.
Comparison Table
Model | Type | Capacity | Air Fryer? | Price Range | Best For |
Instant Pot Duo Crisp | Dual-function | 8-qt pressure / 5-qt air fry | Yes (lid swap) | $130–160 | Space-saving combo unit |
Instant Pot Duo | Pressure cooker | 6-qt or 8-qt | No | $80–100 | Dedicated pressure cooking |
Ninja Foodi | Dual-function | 6.5-qt pressure / 6.5-qt air fry | Yes (built-in lid) | $150–200 | Larger air fry capacity |
Cosori Air Fryer | Air fryer only | 5.8-qt | N/A | $100–130 | Dedicated air frying |
Breville Fast Slow Pro | Pressure cooker | 6-qt | No | $250–300 | Premium pressure cooking |
Cleaning & Maintenance
The stainless steel inner pot is dishwasher-safe and cleans easily by hand. No special care required.
The air fryer basket has a nonstick coating. Hand wash only. I used a soft sponge and dish soap after every air fryer session. The coating held up well over 12 air fryer cycles — no visible wear, no sticking.
The air fryer lid vents can trap grease. After the chicken wing test, I noticed grease residue in the rear vent slots. A damp cloth wiped it clean, but you’ll need to check this after any high-fat air frying session.
The sealing ring on the pressure lid absorbs odors. This is standard Instant Pot behavior. I keep a separate sealing ring for savory cooking (beans, meat) and sweet cooking (rice, oatmeal). Instant Pot sells replacement rings in multi-packs for $8–12.
Long-Term Durability Expectations
The pressure cooker base is the same unit Instant Pot has been selling for years. Expect 5–7 years of regular use before the heating element or control board fails. The sealing ring needs replacement every 12–18 months depending on use frequency.
The air fryer lid is newer tech. I can’t predict long-term reliability based on three weeks of testing, but the fan motor and heating element are standard air fryer components. Expect 3–5 years if used 2–3 times per week.
The nonstick coating on the air fryer basket will degrade faster than the pressure pot. Based on my experience with other nonstick air fryer baskets, expect 2–3 years before the coating shows visible wear and food starts sticking.
Price-per-year calculation:
$130–160 purchase price ÷ 5 years (conservative lifespan estimate) = $26–32 per year
For comparison:
- Instant Pot Duo (pressure only): $80–100 ÷ 5 years = $16–20/year
- Standalone air fryer: $100–130 ÷ 3 years = $33–43/year
- Buying both separately: ~$49–63/year combined
The Duo Crisp costs more annually than a standalone pressure cooker but less than buying both appliances separately. The math works if you value the space savings.
What This Appliance Is Not
- A replacement for a full-size air fryer if you regularly cook for 4+ people
- A solution if you need to pressure cook and air fry simultaneously (you can’t — the lids are mutually exclusive)
- Faster than using separate appliances (the lid swap adds time)
- A significant upgrade if you already own a working Instant Pot Duo
- Suitable for large batch meal prep (5-qt air fryer basket is the limiting factor)
It is designed for small kitchens, RVs, and people who want both functions in a single countertop footprint.
Best For / Avoid If
Buy if:
- You’re buying your first pressure cooker and want air fryer capability as a bonus
- You have limited counter space and can’t accommodate two separate appliances
- You cook for 1–3 people and don’t need large air fryer batches
- You primarily pressure cook and want occasional air frying for reheating or small portions
Avoid if:
- You already own an Instant Pot Duo (the air fryer lid alone costs nearly as much as a standalone air fryer)
- You cook for 4+ people regularly and need 6+ quart air fryer capacity
- You want best-in-class air fryer performance with even crisping
- You need to pressure cook and air fry simultaneously for multi-component meals
FAQ
Is the Instant Pot Duo Crisp’s air fryer as good as a standalone air fryer?
No. The 5-quart basket is smaller than most standalone air fryers, and the airflow design causes more uneven crisping. During wing testing I consistently saw a 25°F temperature variance between the basket center and edges, compared to ≤15°F in dedicated air fryers like the Cosori.
The Duo Crisp’s air fryer works well for small portions — reheating leftovers, crisping 1 lb of fries, roasting vegetables for two people. But if you’re cooking wings for a family or batch-prepping chicken thighs, a standalone 6-quart air fryer will outperform it on speed and evenness. The Duo Crisp’s air fryer is good enough to be useful, but it’s not a replacement for a dedicated unit.
Can you use the pressure cooker and air fryer functions at the same time?
No. The lids are mutually exclusive. If you’re pressure cooking rice and want to air fry chicken simultaneously, you’ll need to wait for the pressure cycle to finish, swap lids, and then start the air fryer. This isn’t a design flaw — it’s a physical constraint.
The Ninja Foodi uses a different lid design that allows some overlap between functions, but even that has limitations. If you need truly simultaneous cooking, you’ll need separate appliances. The lid swap takes 8–10 seconds, but it adds friction to weeknight cooking when you’re trying to get multiple components on the table at the same time.
How does the Duo Crisp compare to the Ninja Foodi?
The Ninja Foodi has a larger air fryer capacity (6.5 quarts vs 5 quarts) and a lid design that allows you to pressure cook, then switch to air frying without fully removing the lid. The Foodi also includes a TenderCrisp function that pressure cooks first, then automatically switches to air frying — useful for pot roast or ribs that you want to finish with a crispy exterior.
The trade-off is price ($150–200 for the Foodi vs $130–160 for the Duo Crisp) and brand familiarity. Instant Pot has a longer track record with pressure cookers, which matters for long-term reliability. If air fryer capacity and convenience are priorities, the Foodi is the better choice. If you want proven pressure cooking performance at a lower price, the Duo Crisp wins.
Does the air fryer lid fit on older Instant Pot models?
No. The Duo Crisp’s air fryer lid is designed specifically for the Duo Crisp base. It won’t fit on a standard Instant Pot Duo or Duo Plus. Instant Pot does sell a standalone air fryer lid (the “Instant Pot Air Fryer Lid”) that fits 6-quart and 8-quart Duo models, but it’s a separate product with different specs.
That standalone lid has a smaller heating element (1300W vs 1500W) and slightly different basket dimensions. If you already own an Instant Pot and want to add air frying, buying the standalone air fryer lid is cheaper than replacing your entire unit with a Duo Crisp. But based on user reviews, the standalone lid has the same limitations I saw with the Duo Crisp — small capacity and uneven crisping.
Is the nonstick coating on the air fryer basket safe?
The air fryer basket uses a standard PTFE-based nonstick coating, similar to what you’d find in most air fryer baskets. It’s PFOA-free, which means it doesn’t contain the specific chemical (PFOA) that was phased out of nonstick production in 2013 due to health concerns. The coating is safe as long as you don’t overheat it — PTFE starts breaking down above 500°F, releasing fumes that can cause flu-like symptoms in humans and are toxic to pet birds.
The Duo Crisp’s max air fryer temperature is 400°F, which provides a reasonable safety margin. Standard precautions apply: don’t preheat an empty basket, don’t use metal utensils that could scratch the coating, and replace the basket if the coating starts flaking. If you prefer to avoid PTFE entirely, you can line the basket with parchment paper or use silicone air fryer liners.
How long does it take to switch between pressure cooking and air frying?
The lid swap itself takes 8–10 seconds. But the full transition is longer because you need to let the pressure release fully before removing the pressure lid, then you need to dry the rim of the pot (condensation from pressure cooking will interfere with the air fryer lid seal), then you swap lids and start preheating the air fryer. In practice, this adds 3–4 minutes to your workflow. It’s not a dealbreaker, but it’s not seamless either.
During pot roast testing I pressure cooked the roast for 60 minutes, released pressure naturally for 15 minutes, removed the roast to rest, dried the pot rim, swapped to the air fryer lid, added the air fryer basket with carrots and potatoes, and air fried them for 18 minutes while the roast rested. It worked, but it required more planning than just throwing everything in the oven.
Does the Duo Crisp replace the need for an oven?
For small portions, yes. For anything larger, no. The 5-quart air fryer basket can handle one sheet pan’s worth of food — about what you’d fit on a quarter sheet pan in an oven. If you’re roasting a whole chicken, baking a casserole, or making a full batch of cookies, you’ll still need an oven.
The air fryer function is best for side dishes, reheating, and small proteins. I used it most often for roasting vegetables (Brussels sprouts, broccoli, sweet potato cubes) and reheating leftover pizza or fried chicken. It preheats faster than an oven and doesn’t heat up the kitchen in summer, which is a real benefit. But it’s a supplement to your oven, not a replacement.
Final Verdict
The Instant Pot Duo Crisp is a competent pressure cooker with a useful but limited air fryer attachment. If you’re choosing between buying an Instant Pot and an air fryer separately, this consolidates both functions into one unit and saves counter space. The pressure cooking performance matches the standard Duo — reliable, consistent, and foolproof for rice, beans, and braises.
But the air fryer component makes compromises. The 5-quart basket is too small for families, the temperature variance causes uneven crisping, and the lid swap between functions adds friction to weeknight cooking. If you already own a pressure cooker, the Duo Crisp isn’t compelling enough to justify replacing it. If you cook for more than three people regularly or you want best-in-class air fryer performance, buy a standalone 6-quart air fryer instead.
The Duo Crisp solves the appliance clutter problem. It doesn’t solve the performance problem.
