To a small bowl add the seasoning mixture ingredients in and stir well.
Line a rimmed sheet pan with parchment paper or aluminum foil. Place the chicken thighs on the sheet pan. Drizzle the chicken with the olive oil and sprinkle the seasoning on each side of the chicken.
Scatter the apparatus around the chicken on the sheet pan. Squeeze the juice of the lemon all over the tops of the asparagus and chicken. Place the slices of butter on the top of the asparagus.
Bake for 13 minutes then flip the chicken, place back into the oven and continue to bake for an additional 13 minutes or until the chicken is completely cooked. Enjoy!
