Ingredients
Servings
4
- 4 bone-in, skin-on chicken thighs (about 1.5 pounds total)
- 1/2 cup almond flour
- 2 tbsp grated Parmesan cheese
- 1 tbsp fresh parsley, finely chopped
- 1 tbsp fresh thyme leaves
- 1 tsp dried oregano
- 1 tsp garlic powder
- 1/2 tsp smoked paprika
- 1/2 tsp salt
- 1/4 tsp black pepper
- 2 tbsp olive oil
- 3 tbsp unsalted butter
- 3 garlic cloves, minced
- 1 tsp fresh lemon juice
- Fresh parsley for garnish (optional)
Instructions
-
Preheat your air fryer to 400°F (200°C) for 5 minutes.
-
In a medium bowl, mix almond flour, Parmesan cheese, parsley, thyme, oregano, garlic powder, smoked paprika, salt, and black pepper to create the herb crust mixture.
-
Pat the chicken thighs dry with paper towels. Drizzle olive oil evenly over each thigh, rubbing it all around to coat thoroughly.
-
Coat each chicken thigh evenly with the herb crust mixture, pressing firmly to adhere the crust on all sides.
-
Place the coated chicken thighs in a single layer in the air fryer basket, skin side up, ensuring no overcrowding. Cook in batches if necessary.
-
Air fry for 18-20 minutes, flipping halfway at 9 minutes, until the skin is golden and crispy and the internal temperature reaches 165°F (74°C).
-
Meanwhile, melt butter in a small skillet over medium heat. Add minced garlic and sauté for 1-2 minutes until fragrant and lightly golden, stirring constantly to prevent burning.
-
Remove from heat and stir in fresh lemon juice. Keep warm until serving.
-
Transfer cooked chicken thighs to a serving plate and drizzle generously with warm garlic butter sauce.
-
Garnish with fresh parsley if desired and serve immediately with your favorite low-carb side dishes.

Air Fryer Model Notes
This recipe for Air Fryer Keto Herb-Crusted Chicken Thighs yields juicy, crispy chicken with a flavorful herb crust, but final texture and cook times may differ depending on your air fryer model.
- Size and Basket Shape: Smaller or compact air fryers may require batch cooking to avoid overcrowding, ensuring even cooking and crisping.
- Heating Element: Top-down elements crisp skin faster, ideal for this recipe.
- Adjust Cooking Time: If your air fryer runs hot or has strong airflow, start checking at 15-16 minutes to prevent over-browning; gentler models may need extra time.
- Flipping: Flip chicken halfway (9 minutes) for even crispness. Rotating baskets may reduce flipping need.
- Preheating: Preheat your air fryer when possible to achieve a golden crust quickly.
Following these tips will help you customize cooking for your model, delivering a healthy, comforting, and family-friendly weeknight Chicken dinner.
Crispiness Control
For perfectly crispy keto herb-crusted chicken, thoroughly pat the chicken skin dry before coating to remove moisture that inhibits crisping.
Cook at a stable 400°F (200°C) to brown almond flour and Parmesan crust without burning. Air fry for the full 20 minutes, flipping once halfway, to maximize crunch.
For a gentler crisp, reduce cook time to 18 minutes and flip carefully to preserve the crust.
Almond flour crisps differently than breading; circulating hot air is critical for crunchiness.
Rest chicken 2-3 minutes outside the basket post-cooking to set the crust. Drizzle garlic butter sauce just before serving to maintain crispiness.
Use these tips to tailor crust crispness, enhancing this family-friendly, comforting Chicken meal.
Reheat In The Air Fryer
To reheat leftovers while preserving crispiness and juiciness:
- Preheat air fryer to 350°F (175°C) for 3-5 minutes.
- Arrange chicken thighs in a single layer, skin side up, without overcrowding.
- Reheat for 6-8 minutes, flipping halfway, until internal temperature reaches 165°F (74°C).
- Avoid high heat to prevent drying or coating damage.
- Warm garlic butter sauce separately and drizzle after reheating.
This reheating method keeps your keto herb-crusted chicken flavorful, crispy, and perfect for meal prep or leftovers.
