I mix onion powder, garlic powder, dried herbs, salt, and pepper in a small bowl. This simple blend ensures the chicken is flavorful from the start and complements the creamy sauce perfectly.
Pat the chicken dry to remove excess moisture, then coat evenly with the seasoning mix. Dry chicken sears better and creates a golden crust that locks in juices.
Heat olive oil in a skillet over medium-high heat. Sear chicken thighs for 3–4 minutes on each side until golden brown, then set aside on a plate while making the sauce.
In the same pan, melt butter and sauté sliced mushrooms until soft and golden. Add garlic and herbs, cooking briefly to release aromatic flavors without burning.
Pour in the heavy cream and simmer gently. Stir in Parmesan cheese until it melts into a smooth, thick sauce that clings to every mushroom and chicken piece.
Return chicken to the pan and coat with sauce. Garnish with chopped parsley and serve immediately for a comforting, creamy dish.
