How Long to Cook Chicken Thighs in Air Fryer: A Complete Guide for Juicy, Crispy Results Every Time

2025-11-07

Cooking chicken thighs in an air fryer is one of the fastest, easiest ways to achieve tender, juicy meat with a crispy, golden-brown exterior—ifyou know how long to cook them. The short answer? Most bone-in, skin-on chicken thighs take ​18–25 minutes​ in a preheated air fryer set to 375–400°F (190–200°C), but the exact time depends on factors like whether the thighs are raw or frozen, bone-in or boneless, and their size. Read on to learn exactly how to time your air fryer session, avoid common mistakes, and ensure your chicken thighs come out perfect every time.

Why Timing Matters: The Science of Air Frying Chicken Thighs

Air fryers work by circulating hot air at high speeds, which cooks food faster than a conventional oven but requires precise timing to avoid overcooking. Chicken thighs have more fat and connective tissue than breasts, making them more forgiving—but only if you cook them long enough to render the fat (for crispiness) without drying out the meat. Undercook them, and you risk pink, unsafe meat; overcook them, and they turn dry and stringy. Understanding the variables that affect cooking time will help you dial in the perfect result.

Key Factors That Change How Long to Cook Chicken Thighs in Air Fryer

Before we dive into specific timings, let’s break down the variables that will adjust your air fryer’s cook time:

1. Bone-In vs. Boneless, Skin-On vs. Skinless

Bone-in thighs take longer to cook than boneless because the bone acts as an insulator, slowing heat transfer. Similarly, skin-on thighs need time to render fat and crisp up, while skinless thighs cook faster but require careful monitoring to stay moist.

2. Raw vs. Frozen

Frozen chicken thighs need to thaw partially (or fully) to cook evenly—cooking them straight from frozen often leads to undercooked interiors or burnt exteriors. If you must cook from frozen, expect to add 5–10 minutes to the total time.

3. Size and Thickness

Larger, thicker thighs (say, 6–8 oz each) need more time than smaller, thinner ones (4–5 oz). Always aim for uniform pieces to ensure even cooking.

Step-by-Step Timings for Common Scenarios

Scenario 1: Cooking Raw, Bone-In, Skin-On Chicken Thighs

This is the most common case. Follow these steps for crispy, juicy results:

  • ​Prep: Pat the thighs dry with paper towels (excess moisture prevents crisping). Season generously with salt, pepper, garlic powder, paprika, or your favorite spices.

  • ​Preheat: Set your air fryer to 375°F (190°C) and let it preheat for 3–5 minutes. Preheating ensures even cooking from the start.

  • ​Cook: Place thighs in a single layer (don’t overcrowd—work in batches if needed). Cook for ​20–25 minutes, flipping halfway through.

  • ​Check Doneness: Use a meat thermometer to check the internal temperature—165°F (74°C) at the thickest part. If not done, cook 2–3 minutes more.

Pro Tip: For extra crispiness, increase the temperature to 400°F (200°C) for the last 5 minutes after flipping.

Scenario 2: Cooking Raw, Boneless, Skinless Chicken Thighs

Boneless thighs cook faster but require attention to avoid drying out:

  • ​Prep: Pound thicker pieces to ½-inch thickness for even cooking. Season as desired.

  • ​Preheat: 375°F (190°C) for 3–5 minutes.

  • ​Cook: Place in a single layer. Cook for ​12–18 minutes, flipping halfway. Thinner thighs may be done at 12–15 minutes; thicker ones need 16–18.

  • ​Check Doneness: Internal temp should reach 165°F (74°C). Let rest 5 minutes before slicing to lock in juices.

Scenario 3: Cooking Frozen Chicken Thighs (No Thawing)

If you forgot to thaw, follow these adjusted steps:

  • ​Prep: Remove from packaging and pat dry. Season (you can use less seasoning initially, as some may burn in longer cook times).

  • ​Preheat: 375°F (190°C) for 3–5 minutes.

  • ​Cook: Place in a single layer. Cook for ​25–30 minutes, flipping halfway. If the exterior is browning too fast, cover loosely with foil for the first 15 minutes.

  • ​Check Doneness: Internal temp must hit 165°F (74°C). If still undercooked, add 2–3 minutes and check again.

Scenario 4: Reheating Cooked Chicken Thighs

Leftover thighs? Air frying is the best way to reheat them without drying out:

  • ​Prep: Let sit at room temp for 10 minutes. Lightly brush with oil or spray.

  • ​Preheat: 375°F (190°C) for 3–5 minutes.

  • ​Cook: Place in a single layer. Cook for ​8–12 minutes, flipping once, until heated through (internal temp 165°F/74°C).

How to Tell When Chicken Thighs Are Done (Beyond the Thermometer)

A meat thermometer is the most reliable tool, but here are visual and tactile cues:

  • ​Juices Run Clear: Pierce the thickest part with a fork or knife—if the juices are clear, it’s done. Pink juices mean it needs more time.

  • ​Skin Is Crisp and Golden: The skin should puff up, bubble, and turn deep brown (not burnt).

  • ​Meat Pulls Away from the Bone: For bone-in thighs, the meat should easily separate from the bone when poked.

Common Mistakes That Throw Off Cooking Time (and How to Fix Them)

Even with the right time, these errors can ruin your chicken thighs:

Mistake 1: Overcrowding the Air Fryer

If you pack too many thighs in, steam builds up instead of hot air circulating. This leads to soggy skin and uneven cooking. Fix: Cook in batches or use a larger air fryer basket.

Mistake 2: Skipping the Preheat

Air fryers need time to reach target temperature. Skipping preheating means the thighs start cooking in a cold environment, extending total time and risking undercooking. Fix: Always preheat for 3–5 minutes.

Mistake 3: Not Drying the Thighs

Wet skin steams instead of crisps. Fix: Pat thighs thoroughly with paper towels before seasoning.

Mistake 4: Overcooking for “Extra Safety”

Chicken is safe at 165°F (74°C), but cooking beyond that dries out the meat. Fix: Trust your thermometer—remove thighs as soon as they hit 165°F.

Advanced Tips for Perfect Air Fryer Chicken Thighs

  • ​Brine First: Soak thighs in a saltwater brine (1/4 cup salt per 4 cups water) for 30 minutes before cooking. This locks in moisture, even if you slightly overcook them.

  • ​Finish Under the Broiler: For extra-crispy skin, broil on high for 1–2 minutes after air frying. Watch closely—broilers work fast.

  • ​Marinate Overnight: Let thighs sit in a marinade (like soy sauce, honey, and ginger) for 8–12 hours. This adds flavor and helps tenderize the meat.

Final Thoughts: Mastering Air Fryer Chicken Thighs

Cooking chicken thighs in an air fryer is all about adjusting time based on their type, size, and whether they’re fresh or frozen. By following the guidelines above—preheating, drying the meat, using a thermometer, and avoiding overcrowding—you’ll consistently get juicy, flavorful thighs with a crispy crust. Remember: practice makes perfect, so don’t be afraid to tweak times slightly based on your air fryer model and personal preference. With these tips, you’ll never wonder “how long to cook chicken thighs in air fryer” again—you’ll know, and you’ll nail it every time.
