Preheat your oven to 375Β°F (190Β°C).
Season the chicken breasts on both sides with a pinch of salt and pepper.
Heat 1 tablespoon of olive oil in a large skillet over medium-high heat. Sear the chicken breasts for 3-4 minutes on each side until golden brown (they don't need to be fully cooked). Remove chicken from the skillet and set aside.
In the same skillet, add the remaining tablespoon of olive oil and butter. Once melted, sautΓ© the sliced mushrooms over medium heat until they release their liquid and brown slightly, about 5 minutes.
Add the minced garlic to the mushrooms and cook for another minute until fragrant.
Sprinkle the flour over the mushroom mixture and stir well to coat. Cook for 1-2 minutes to remove the raw flour taste.
Gradually pour in the chicken broth while stirring to avoid lumps, followed by the heavy cream. Mix well until the sauce is smooth.
Stir in the dried thyme, 1 teaspoon of salt, and 0.5 teaspoon of black pepper. Let the sauce simmer for 2-3 minutes until it thickens slightly.
Place the seared chicken breasts into a greased casserole dish. Pour the mushroom sauce over the chicken, spreading it evenly.
Sprinkle the shredded cheddar cheese over the sauce, followed by the bread crumbs for a crispy topping.
Bake in the preheated oven for 20-25 minutes until the chicken is fully cooked and the topping is golden brown.
Garnish with chopped parsley, if desired, and serve warm.
