Description

A comforting Creamy Chicken Mushroom Spaghetti Bake featuring tender chicken, sautéed mushrooms, and spaghetti noodles in a rich, garlicky cream sauce baked to perfection with a cheesy topping. This hearty casserole is perfect for a cozy family meal.


Ingredients

Scale

Pasta

  • 8 ounces spaghetti noodles (or gluten free pasta of your choice)

Chicken and Mushrooms

  • 5 tablespoons butter (divided)
  • 3 large cloves garlic (minced)
  • 8 ounces baby mushrooms (sliced thin)
  • 3 cups cooked chicken (chopped small)

Sauce

  • 2 tablespoons all purpose flour (brown rice flour for gluten free)
  • 2 cups chicken broth
  • 1 cup heavy cream
  • ½ teaspoon kosher salt (adjust as needed)
  • ½ teaspoon freshly ground black pepper
  • ½ cup shredded Parmesan or Pecorino Romano cheese
  • 2 tablespoons fresh Italian parsley (chopped)


Instructions

  1. Preheat and Cook Pasta: Preheat the oven to 350°F. Cook and drain the spaghetti noodles according to package instructions, then set aside.
  2. Sauté Garlic and Mushrooms: Melt 3 tablespoons of butter in a large skillet over medium-high heat. Add the minced garlic and sliced mushrooms, cooking for 3-5 minutes until browned, stirring occasionally.
  3. Add Chicken: Add the chopped cooked chicken to the skillet, toss to coat with the garlic and mushrooms, then remove from heat.
  4. Prepare the Sauce: Melt the remaining 2 tablespoons of butter in a saucepan over medium heat. Whisk in the flour and cook briefly, then slowly whisk in the chicken broth. Increase heat to medium-high and bring to a simmer.
  5. Simmer with Cream: Cook for 2 minutes, then add the heavy cream. When the sauce simmers again, reduce heat to medium-low and simmer, stirring constantly, for 8-10 minutes until slightly thickened. Season with salt and pepper to taste.
  6. Assemble Bake: In a 9×13 baking dish, spread the cooked pasta evenly, top with the chicken and mushroom mixture, then pour the creamy sauce over everything to coat thoroughly.
  7. Bake: Sprinkle shredded Parmesan or Pecorino cheese over the top and bake in the preheated oven for 20 minutes until the sauce is bubbling and the cheese is melted.
  8. Garnish and Serve: Stir the bake gently, sprinkle with chopped fresh Italian parsley if desired, and serve hot.

Notes

  • The BEST chicken tetrazzini starts with sautéed mushrooms, garlic, and tender chicken tossed in a creamy sauce with pasta.
  • Use gluten-free pasta and brown rice flour for a gluten-free version.
  • Adjust salt based on the saltiness of your chicken broth.
  • Leftovers can be refrigerated for up to 3 days and reheated in the oven or microwave.
