Cheesy Chicken Mushroom Bake (Printable)

Tender chicken baked with mushrooms in a creamy, cheesy sauce, finished golden and sprinkled with parsley.

# What You'll Need:

→ Meats

01 - 4 boneless, skinless chicken breasts

→ Vegetables

02 - 8 oz mushrooms, sliced
03 - 1 small onion, finely chopped
04 - 2 garlic cloves, minced

→ Sauce & Dairy

05 - 3/4 cup heavy cream
06 - 1/2 cup chicken broth
07 - 1 1/2 cups shredded mozzarella cheese
08 - 1/2 cup grated Parmesan cheese
09 - 1 tablespoon all-purpose flour (or gluten-free alternative)
10 - 2 tablespoons unsalted butter

→ Spices & Herbs

11 - 1 teaspoon dried thyme
12 - 1/2 teaspoon black pepper
13 - 1/2 teaspoon salt
14 - 2 tablespoons fresh parsley, chopped (for garnish)

# How To Make:

01 - Preheat oven to 400°F. Lightly grease a 9x13-inch baking dish with butter or cooking spray.
02 - Pat chicken breasts dry and season both sides evenly with salt, pepper, and dried thyme.
03 - In a large skillet over medium heat, melt the butter. Add the chopped onion and minced garlic; sauté for 2 to 3 minutes until softened and fragrant.
04 - Add the sliced mushrooms to the skillet and cook for 5 to 6 minutes, stirring occasionally, until golden brown and all released liquid has evaporated.
05 - Sprinkle the flour evenly over the mushroom mixture. Stir continuously and cook for 1 minute to form a light roux.
06 - Gradually pour in the chicken broth and heavy cream, stirring constantly to prevent lumps. Bring to a gentle simmer and cook for 2 to 3 minutes until the sauce slightly thickens.
07 - Remove the skillet from heat. Stir in half of the mozzarella and all of the Parmesan cheese until fully melted and smooth.
08 - Arrange the seasoned chicken breasts in a single layer in the prepared baking dish. Pour the mushroom-cheese sauce evenly over the chicken, ensuring full coverage.
09 - Sprinkle the remaining mozzarella cheese evenly across the top of the casserole.
10 - Bake uncovered for 30 to 35 minutes, or until the chicken reaches an internal temperature of 165°F and the top is bubbly and golden brown.
11 - Remove from the oven and let rest for 5 minutes. Garnish with freshly chopped parsley before serving.

# Expert Tips:

01 -
  • It turns five everyday ingredients into something that tastes like you spent three hours cooking.
  • The creamy mushroom sauce basically makes itself while you season the chicken.
  • Leftovers reheat beautifully for lunch the next day, if you ever have any.
02 -
  • Do not rush the mushroom cooking step because undercooked mushrooms will leak water into your sauce and make it runny.
  • If the chicken breasts are very thick, pound them slightly so they cook through before the cheese burns on top.
03 -
  • Let the sauce cool for two minutes before pouring it over the chicken because a boiling hot sauce can start cooking the exterior of the breasts prematurely.
  • Shred your own cheese from a block instead of using pre shredded bags, which contain anti caking powders that prevent smooth melting.
