In a small measuring pitcher or bowl add pineapple juice, coconut aminos, sesame oil, minced garlic and thyme. Use fork or small whisk to thoroughly combine.
Pour marinade in bag over chicken press to remove air and seal tightly. Shake bag to get the chicken coated in marinade. Place bag flat in refrigerator. Marinate 30 minutes up to overnight flipping once halfway through.
Preheat oven to 425℉. Cover baking sheet with aluminum foil and top with wire rack if desired. Place chicken drumsticks in a single layer on baking sheet or wire rack.
Bake 35-38 minutes until internal temperature reads 165℉. If the drumsticks are cooked on a wire rack the skin should come out nice and crispy. If the drumsticks are cooked directly on a baking sheet broil an additional 4-8 minutes to create crispy skin. Serve warm.
