How to cook deliciously - Cheesy Chicken and Mushroom Bake

1 . Stage

Preheat the oven to 375 degrees F (190 degrees C). Grease a baking dish lightly.

2 . Stage

Sprinkle salt and pepper on chicken. Heat butter in a pan over medium-high heat. Add chicken and brown on all sides, 5 to 7 minutes. Remove chicken and place in the prepared baking dish.

3 . Stage

Stir mushrooms, onion, garlic, and flour into the remaining butter in the saucepan and saute over medium-high heat until softened, about 5 minutes. Add chicken broth and bring to a boil while scraping the "good stuff" off of the bottom of the saucepan, letting it add to the flavor. Cook until thickened to your liking; drizzle over chicken.

4 . Stage

Bake in the preheated oven for 30 minutes. Sprinkle with Parmesan cheese, mozzarella cheese, and scallions. Continue to bake until chicken is no longer pink in the center and cheese is melted, about 10 minutes more. An instant-read thermometer inserted into the center should read at least 165 degrees F (74 degrees C).
