Lightly grease your baking dish and arrange the chicken breasts in a single layer. I season both sides with salt and pepper so the flavor goes all the way through. This step ensures the chicken doesn’t taste bland once baked.
I heat olive oil and butter in a skillet, then add the sliced mushrooms. They release moisture at first, but after a few minutes, they turn golden and flavorful. This step builds the base of the sauce.
Once the mushrooms are browned, I add garlic and thyme, letting them cook briefly until fragrant. Then I pour in the chicken broth and cream, stirring gently. The sauce thickens slightly as it simmers.
I pour the mushroom sauce over the seasoned chicken in the baking dish. Everything goes into the oven until the chicken is cooked through and tender. The sauce bubbles gently, soaking into the chicken.
After baking, I sprinkle fresh parsley on top. It brightens the dish and makes it look just as good as it tastes before serving.
