Ingredients

• 4 pieces boneless, skinless chicken breasts
• 2 tablespoons olive oil
• 1 teaspoon salt
• 0.5 teaspoon black pepper
• 2 tablespoons butter
• 1 medium yellow onion, diced
• 3 cloves garlic cloves, minced
• 250 grams mushrooms, sliced
• 2 tablespoons all-purpose flour
• 2 cups chicken broth
• 1 cup heavy cream
• 0.5 cup grated Parmesan cheese
• 0.5 teaspoon dried thyme
• 3 cups cooked white rice or pasta
• 1 cup shredded mozzarella cheese
• 2 tablespoons fresh parsley, chopped

Directions

Step 1

Preheat your oven to 375°F (190°C).

Step 2

Season the chicken breasts with salt and black pepper on both sides.

Step 3

In a large skillet, heat olive oil over medium-high heat. Cook the chicken for 3-4 minutes per side, until golden brown. Transfer to a plate and set aside.

Step 4

In the same skillet, melt the butter over medium heat. Add the diced onion and cook for 3-4 minutes until softened. Stir in the minced garlic and cook for an additional 1 minute.

Step 5

Add the sliced mushrooms to the skillet and cook for 5-6 minutes, until they release their moisture and are tender.

Step 6

Sprinkle the flour over the mushroom mixture and stir well to coat. Cook for 1 minute to eliminate the raw flour taste.

Step 7

Gradually whisk in the chicken broth, making sure there are no lumps. Bring the mixture to a simmer and cook for 3-4 minutes, until thickened.

Step 8

Stir in the heavy cream, Parmesan cheese, and dried thyme. Simmer for 2-3 minutes, then remove from heat.

Step 9

In a large casserole dish, spread the cooked white rice or pasta evenly on the bottom. Place the seared chicken breasts on top of the rice or pasta.

Step 10

Pour the mushroom sauce over the chicken, spreading it evenly.

Step 11

Sprinkle the shredded mozzarella cheese over the top.

Step 12

Bake in the preheated oven for 25-30 minutes, until the cheese is melted and bubbly, and the casserole is heated through.

Step 13

Remove from the oven and let it rest for 5 minutes. Garnish with chopped parsley before serving.
