Ingredients

Main Ingredients

  • 1.5 lb Chicken breast, boneless and skinless
  • 8 oz Sliced mushrooms
  • 1.5 cups Heavy cream Warm gently to avoid separation
  • 3/4 cup Chicken broth
  • 0.5 cup Parmesan cheese, grated
  • 3 cloves Garlic, minced
  • 1 teaspoon Thyme
  • 1 tablespoon Neutral cooking oil Use in skillet for cooking chicken
  • to taste Salt Add after sauces and cheese

Instructions

Preparation and Cooking

  • Cut the chicken into even bite-size pieces and cook it thoroughly in a skillet with a little neutral oil if needed.
  • Preheat your oven to 375°F (190°C).
  • Sear the chicken breasts in a pan until they’re golden brown.
  • In the same pan, create a creamy garlic mushroom sauce by sautéing the mushrooms and adding garlic, heavy cream, chicken broth, and thyme.
  • Pour the sauce over the seared chicken in a baking dish, then sprinkle a generous amount of parmesan cheese on top.
  • Bake in the preheated oven for 20–30 minutes until the chicken is cooked through and the cheese is melted and bubbly.
  • Check after 20 minutes; if the topping browns too quickly, cover loosely with foil.
  • Rest for 5 minutes before serving.

Notes

For easier assembly, prepare the components ahead and refrigerate. Warm dairy gently to avoid separation. Store leftovers promptly and reheat until hot throughout.
