This Easy Cheesy Chicken Casserole is the ultimate comfort food dinner made with tender chicken, egg noodles, mixed vegetables, and gooey melted cheese. An easy one-pan casserole recipe perfect for busy weeknights with no need to boil the noodles first!
Preheat oven to 350°F. Butter the bottom of a casserole dish.
Cut the chicken breast into bite-size pieces.
Add the chicken breast pieces to the casserole dish. Season with 2 teaspoons garlic powder, chicken bouillon, and 1 teaspoon pepper.
Add the uncooked egg noodles and frozen mixed vegetables to the dish.
In a mixing bowl, whisk together the cream of chicken soup, milk, chicken broth, 1 teaspoon garlic powder, and ½ teaspoon pepper until smooth.
Pour the soup mixture evenly over the casserole. Use a spoon to gently press the noodles down so all of the pasta has some of the liquid mixture on top. *make sure every noodle has some liquid on it, otherwise it will come out crunchy.
Cover tightly with foil and bake for 1 hour.
Remove the foil and stir the casserole. Change the oven setting to broil.
Sprinkle the sharp cheddar and mozzarella cheese evenly over the top. Broil until the cheese is melted, bubbly, and golden brown, about 5 minutes. Keep a close eye on it so the cheese does not burn.
