Smothered Cheesy Chicken Casserole

Cooked Angel hair pasta with a creamy, cheesy Caesar sauce is mixed with sauteed mushrooms & onions, then topped with chicken and bacon for this Smothered Cheesy Chicken Casserole.

I am always on the hunt for new dinner recipes that aren’t too fussy and are delicious. If you are too, I have to recommend this recipe for Smothered Chicken Casserole that I found at Heather Likes Food.

I made some minor changes just to fit what I had already in the fridge. For example the original recipe calls for marinating the chicken breasts in Caesar dressing, but I was out so I used a creamy Asiago Peppercorn dressing instead.

The cheese choice is flexible

The other change I made was what cheese I used. The original recipe called for Gruyere but I opted to use a mix of mozzarella and smoked white cheddar I had that needed to be used up. So in summation this recipe is very flexible based on what you have in the fridge. Many thanks to Heather for the recipe. Enjoy!

  • 1/2 cup prepared Caesar salad dressing I used an Asiago dressing
  • 4 large boneless & skinless chicken breasts
  • 4 slices bacon
  • 8 oz. sliced mushrooms
  • 1 cup onion diced
  • 3 tbsp all-purpose flour
  • 3 tbsp butter
  • 1 tsp kosher salt
  • 1/4 tsp pepper
  • 2 tbsp fresh lemon juice
  • 3 cups chicken broth
  • 1 1/2 cups heavy cream
  • 1 cup Gruyere cheese grated (I used a mix of Mozzarella and Smoked Cheddar. Use whatever melts well that you like!)
  • 2 cups fresh tomatoes diced
  • 1/4 cup fresh parsley minced (I used about 1 Tbsp. dried)
  • 1 lb angel hair pasta


  • Marinate the chicken breasts in Caesar dressing for at least 3 hours, up to overnight.
  • Preheat oven to 350-f. Cook bacon until crisp, remove from pan and drain off all but about 2 tbsp of the fat. Heat pan to medium-high heat.
  • Remove chicken from marinade and cook in bacon fat until well browned. (You don’t have to cook the chicken through, just get some color on it.) Remove chicken from pan and place in casserole dish.
  • Drain off all the bacon fat from the pan and add 3 tbsp of butter. Once melted stir in the onion and mushrooms. Cook until soft and starting to caramelize- 5-7 minutes.
  • Stir 3 tbsp of flour into the onions and mushrooms and cook for 1 minute.
  • Stir broth and cream into the flour mixture, bring to boil -constantly stirring- for 2 minutes. Remove from heat.
  • Stir in salt, pepper, lemon juice, cheese, and parsley and pour over the chicken in the casserole dish. Top with fresh tomatoes and bake, uncovered for 20-25 minutes or until the sauce is bubbly and chicken is cooked through.
  • While the chicken is baking, cook 1 lb angel hair pasta on the stove-top and drain. Remove chicken from the oven, stir pasta into the sauce and serve topped with crumbled bacon and more fresh parsley.
