In a small bowl, combining the chicken seasoning mixture and set aside. Cut the chicken thighs into 2" chunks. Place them in a large bowl, drizzle the avocado oil, then sprinkle the chicken seasoning mixture. Toss until the chicken is fully coated.
To a small saucepan, add the butter and garlic and heat until butter is softened but not fully melted. Then add in red pepper flakes, seasonings, and parmesan. Whisk together until combined.
Set aside 1/3 of the parmesan butter sauce and reserve the remaining sauce for basting the cooked chicken.
Place the chicken pieces on a parchment-lined baking sheet and cook at 425 for 20 minutes, baste and flip the pieces over, and cook another 10-15 minutes.
Once the chicken is done cooking, drizzle them with the reserved parmesan butter sauce and sprinkle with extra parmesan cheese. I like serving this on a bed of rice and a quick sautéed green vegetable. Enjoy!!
