Creamy Chicken and Mushroom Casserole

This casserole features chicken thighs browned in olive oil with skin on and bone in (or breasts if preferred), layered with a sautéed mixture of sweet onion, garlic, baby bella mushrooms, and herbs. A creamy Parmesan sauce made from butter, flour, chicken broth, heavy cream, and cheese is poured over before baking. The result is a rich, hearty dish combining tender chicken with savory mushrooms in a luscious sauce.

Description

Creamy Chicken and Mushroom Casserole is prepared by first browning chicken thighs in olive oil until golden on both sides. Using skin-on, bone-in thighs adds flavor, though chicken breasts can be substituted. Meanwhile, diced sweet onion and minced garlic are sautéed before adding sliced baby bella mushrooms and seasoning with thyme, paprika, parsley, salt, and black pepper. This mixture is cooked until softened and spread as a base layer in a lightly greased casserole dish.

The browned chicken pieces are placed atop the mushroom bed. A sauce is then made by melting butter and stirring in flour to form a roux, then gradually whisking in chicken broth and heavy cream to create a smooth, creamy base. Grated Parmesan cheese is added to enrich the sauce, which is seasoned with salt and black pepper. This sauce is poured over the chicken and mushroom layers.

The casserole is baked in a moderately hot oven until the chicken is fully cooked and the sauce has thickened and bubbled. The dish offers tender chicken with a golden crust, enveloped in a savory, creamy sauce with the earthy flavor of mushrooms and fragrant herbs. It is suitable as a comforting main course served alongside simple sides.

Ingredients

Servings
  • 6 chicken thighs bone-in/skin-on or use chicken breasts
  • 3 tablespoons olive oil more if needed

Cook Mushroom Mixture:

  • 1 sweet onion diced
  • 6 cloves garlic minced
  • 1 pound baby bella mushroom cleaned, stem removed and roughly sliced
  • 1 teaspoon thyme
  • 1 teaspoon paprika
  • 1 teaspoon parsley dried
  • salt to taste
  • black pepper to taste

Sauce:

  • 2 tablespoons butter unsalted
  • 3 tablespoons all-purpose flour
  • 1 1/2 cups chicken broth low sodium and preferably organic
  • 1 cup heavy whipping cream or half and half
  • 1 cup Parmesan Cheese grated
  • salt to taste
  • black pepper to taste

Instructions

  1. Preheat oven to 375 degrees F. Arrange the oven rack in the middle of the oven.
  2. Very lightly grease a 9x13-inch casserole/baking dish and set it aside.

Cook the chicken:

  1. Heat about three tablespoons of olive oil in a frying pan or cast-iron skillet over medium-high heat.
  2. Once hot, add the chicken thighs, skin side down, to the hot oil. Cook on both sides for 1-2 minutes until golden brown.
  3. Remove the chicken thighs from the skillet and set aside on a plate, covering with foil. Later, transfer the chicken thighs to the casserole baking dish.

Cook the mushroom mixture:

  1. If needed, add more oil to the pan and add the diced onion. Cook for 1-2 minutes, stirring occasionally.
  2. Add garlic and cook for another minute, stirring. Add sliced mushrooms, thyme, dried parsley, paprika, salt, and pepper to the pan, stir, and cook for about five minutes or until softened.
  3. Spread the mushroom mixture on the bottom of the casserole dish.
  4. Return the pan to the stove over medium heat.

Sauce:

  1. Next, melt two tablespoons of butter in the same pan over medium heat. Add the flour and whisk it until lightly golden and thoroughly combined, about 1-2 minutes.
  2. Slowly and still whisking, add 1 1/2 cups chicken broth and whisk until smooth.
  3. Add 1 cup of heavy whipping cream; you can use light cream or half and half. Whisk until smooth and bring to a simmer for about 2 minutes. Season with salt and pepper to taste.
  4. Stir in the grated Parmesan cheese until thoroughly combined and the cheese is melted.
  5. Pour the sauce over the mushroom mixture into the baking dish. If preferred, sprinkle some extra parmesan cheese on top. Add chicken, skin side up. Then, cover with foil.

Bake:

  1. Transfer the dish to the oven, and bake the casserole covered for 30-40 minutes until the chicken is tender and cooked through.
  2. Before you remove it from the oven, discard the foil cover and broil for a few minutes until the chicken is golden.

Serve:

  1. Just before serving, you can sprinkle the dish with chopped parsley.
