In the mean time, while the chicken is baking, make the sauce. Thoroughly clean and dry the skillet you used for cooking chicken thighs. Heat 1 teaspoon olive oil and 1/2 tablespoon butter on medium heat in this cleaned skillet. Add minced garlic and cook, constantly stirring, for about 30 seconds. Add chicken stock and 1 teaspoon lemon seasoning to the skillet and bring to boil. Add heavy cream and bring to boil.
