These air fryer chicken thighs cook up with crisp skin and juicy meat, then get finished with a silky tarragon mustard cream sauce that tastes restaurant-level without a lot of steps.
Why This Air Fryer Recipe Works
Chicken thighs are forgiving, and the air fryer’s circulating heat helps render the skin while keeping the inside tender. Starting skin-side down for a few minutes helps begin rendering fat, then flipping lets the skin crisp up where it counts.
The sauce is made in a skillet while the chicken rests, so nothing gets soggy. Dijon brings sharpness, tarragon adds that classic French herb note, and cream ties it together into a smooth pan-style sauce you can spoon over the top.
1 tsp baking powder (optional, helps with crispier skin)
1 tsp olive oil (optional, just to help seasoning adhere)
1 tbsp unsalted butter
1 small shallot, finely minced (about 2 tbsp)
1 clove garlic, minced
1/2 cup chicken broth
3/4 cup heavy cream
1 1/2 tbsp Dijon mustard
1 to 2 tsp fresh tarragon, chopped (or 1/2 to 3/4 tsp dried)
1 tsp lemon juice (optional, to brighten)
How to Make Air Fryer Chicken Thighs with Tarragon Mustard Cream Sauce in the Air Fryer
1) Pat the chicken thighs very dry with paper towels. Dry skin is the difference between browned and actually crisp.
2) In a small bowl, mix salt, pepper, garlic powder, paprika, and baking powder (if using). Lightly rub thighs with olive oil (optional), then season all over, focusing on the skin side.
3) Preheat the air fryer to 380°F for 3–5 minutes (if your model preheats). Place thighs in the basket in a single layer.
4) Cook skin-side down for 8 minutes. Flip skin-side up and continue cooking until the skin is deeply browned and the thickest part reads 175–185°F. Transfer to a plate and rest 5–10 minutes.
5) While the chicken rests, make the sauce. In a small skillet over medium heat, melt butter. Add shallot and cook 2–3 minutes until softened. Add garlic and cook 30 seconds.
6) Pour in chicken broth and simmer 2–3 minutes to reduce slightly. Stir in cream and Dijon. Simmer gently 3–5 minutes until lightly thickened (don’t hard-boil).
7) Stir in tarragon and lemon juice (if using). Taste and adjust with a pinch of salt or extra mustard. Spoon sauce over the thighs and serve.
Air Fryer Time and Temperature
Air fry at 380°F, then let the final doneness be guided by temperature, not the clock.
Preheat: 380°F for 3–5 minutes (recommended)
Cook: 8 minutes skin-side down
Flip: cook 10–14 minutes skin-side up
Target internal temp: 175–185°F in the thickest part (thighs get more tender above 170°F)
Cook time varies by air fryer size and thigh thickness. If you’re using smaller thighs, start checking around the 18-minute mark total.
Tips for the Best Results
Dry the skin thoroughly before seasoning; moisture is the enemy of crisp.
Don’t overcrowd the basket. Air needs space to circulate or the skin steams.
If your thighs have a lot of loose skin, tuck it under slightly so it doesn’t flap and tear.
Rest the chicken before saucing. Resting keeps juices in the meat and keeps the skin from softening as fast.
Keep the sauce at a gentle simmer so the cream stays smooth.
If the chicken is cooked through but the skin isn’t as crisp as you want, add 2–3 minutes at 400°F at the end, watching closely.
Variations and Substitutions
Boneless, skinless thighs: Cook at 380°F for 10–14 minutes total, flipping halfway. You’ll lose the crisp skin, but the sauce still shines.
No tarragon: Swap in chives or parsley for a different vibe. If using dried herbs, start small and let the sauce sit 2 minutes before adjusting.
Mustard options: Whole-grain mustard works for a speckled sauce; use the same amount as Dijon.
Lighter sauce: Use half-and-half instead of heavy cream; simmer a little longer to thicken.
Store chicken and sauce separately if you can; it helps preserve the skin. Refrigerate in airtight containers for up to 3–4 days.
Reheat chicken thighs in the air fryer at 350°F for 4–7 minutes until hot, then spoon warmed sauce over the top. Warm the sauce gently in a skillet over low heat (or microwave in short bursts), adding a splash of broth if it thickens too much.
Do I need to preheat the air fryer for chicken thighs?
Preheating helps the skin start crisping right away and can improve browning. If your air fryer doesn’t preheat, just add 1–2 minutes to the cook time and keep an eye on color.
What internal temperature should chicken thighs be cooked to?
Thighs are safe at 165°F, but they turn more tender and juicy as they climb higher. Aim for 175–185°F in the thickest part without touching bone.
Why isn’t my chicken skin getting crispy in the air fryer?
Usually it’s moisture or crowding. Pat the skin dry, avoid overlapping pieces, and consider the baking powder trick for better texture.
Can I make the tarragon mustard cream sauce ahead of time?
Yes. Make it up to 2 days ahead and refrigerate, then warm gently over low heat, whisking until smooth. If it thickens, loosen with a splash of broth.
Can I use dried tarragon instead of fresh?
Dried tarragon works well here. Use about 1/2 to 3/4 teaspoon, then taste after the sauce simmers for a minute since dried herbs need a little time to bloom.
