Take a large mixing bowl and add the chicken pieces into it. Pour in the Greek yogurt, then add garlic powder, paprika, salt, and black pepper. Using a spoon, spatula, or clean hands, mix everything thoroughly until each piece of chicken is evenly coated in the marinade. Make sure there are no dry spots—every piece should be fully covered, as this step is key for flavor and tenderness.

Once the chicken is well coated, cover the bowl with a lid, plastic wrap, or foil. Let it marinate for at least 30 minutes at room temperature if you're short on time, or place it in the refrigerator for several hours or overnight for deeper flavor and extra juicy results. The longer it marinates, the more tender and flavorful the chicken will become.

While the chicken is marinating, prepare the coating mixture. In a separate bowl, add almond flour, unflavored protein powder, and grated parmesan cheese. Mix everything together well until the ingredients are evenly distributed. This coating is what gives the chicken its crispy, golden texture, so make sure it’s fully combined.

After marination, take one piece of chicken at a time from the bowl. Allow any excess marinade to drip off slightly—this helps prevent the coating from becoming too wet or clumpy. Place the chicken into the coating mixture and press it gently on all sides, ensuring it is fully covered. Lightly press the coating onto the surface so it sticks well and forms a solid crust during cooking.

Preheat your air fryer to 180°C for a few minutes. This step is important because placing the chicken into a properly heated air fryer helps start the crisping process immediately. Lightly spray the air fryer basket with oil to prevent sticking and to promote even browning.

Arrange the coated chicken pieces in a single layer inside the air fryer basket. Make sure there is space between each piece so hot air can circulate properly. Avoid overcrowding, as this can lead to uneven cooking and less crispy results. If needed, cook in batches.

Lightly spray the tops of the chicken pieces with oil. This small step makes a big difference—it helps the coating turn golden brown and crispy, similar to traditional fried chicken but without deep frying.

Cook the chicken for 15 to 18 minutes, depending on the size of your pieces. About halfway through cooking, open the air fryer and carefully flip each piece using tongs. This ensures both sides cook evenly and develop a consistent crispy texture.

Once the cooking time is complete, check the chicken to make sure it is fully cooked through. The outside should be golden and crispy, and the inside should be juicy with no pink remaining. If needed, cook for an additional 2–3 minutes.

Remove the chicken from the air fryer and let it rest for a few minutes before serving. This allows the juices to redistribute inside the meat, making each bite more tender and flavorful.
