Cheesy Chicken Mushroom Bake (Printable Version)

Tender chicken in a creamy mushroom and cheese sauce, baked until golden; an easy, comforting family main.

# 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)

# Directions:

01 - Preheat oven to 400°F. Lightly grease a 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 toast the flour and remove any raw taste.
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 thickens slightly.
07 - Stir in half of the mozzarella and all of the Parmesan cheese. Continue stirring until fully melted and smooth, then remove the skillet from heat.
08 - Arrange the seasoned chicken breasts in the prepared baking dish in a single layer. Pour the mushroom-cheese sauce evenly over the chicken, ensuring full coverage.
09 - Sprinkle the remaining mozzarella cheese evenly over the top of the casserole.
10 - Bake in the preheated oven 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 to allow the sauce to set. Garnish with freshly chopped parsley before serving.

# Quick Tips:

01 -
  • The sauce practically builds itself while the mushrooms cook down, so you never need a separate step for making a roux from scratch.
  • It reheats beautifully the next day, which means lunch is already sorted and honestly tastes even better.
  • Everything bakes in one dish, leaving you with almost nothing to wash after dinner.
02 -
  • Do not rush the mushroom cooking step because undercooked mushrooms will leach water into the sauce and make it soupy.
  • Adding a splash of dry white wine with the cream transforms the flavor from simple to dinner party worthy with almost no extra effort.
03 -
  • Slice the chicken breasts horizontally if they are very thick so the bake cooks evenly without drying out the edges.
  • Shred your own cheese from a block rather than using pre shredded bags because the anti caking agents prevent it from melting smoothly.
