This Mushroom and Chicken Alfredo Casserole is a rich and comforting dish featuring tender chicken, savory mushrooms, creamy Alfredo sauce, and gooey melted cheese. Perfect for cozy evenings or casual gatherings.

Ingredients

3 cups cooked shredded or diced chicken

8 oz uncooked pasta (penne or rotini recommended)

2 tablespoons butter

1½ cups sliced mushrooms

2 cloves garlic, minced

2 cups Alfredo sauce (homemade or store-bought)

1 cup shredded mozzarella cheese

½ cup grated Parmesan cheese

Salt and black pepper, to taste

Chopped parsley, for garnish (optional)

Instructions

  1. Preheat the oven to 350°F (175°C).
  2. Cook the pasta according to package instructions, drain, and set aside.
  3. In a large skillet, melt butter over medium heat. Add sliced mushrooms and sauté until they soften, about 5 minutes.
  4. Add minced garlic to the skillet and sauté for another 30 seconds until fragrant.
  5. Stir in the cooked chicken and Alfredo sauce, cooking for an additional 3–4 minutes until everything is heated through.
  6. Season the mixture with salt and black pepper to taste.
  7. In a large mixing bowl, combine the cooked pasta and the chicken-mushroom sauce mixture. Stir until well combined.
  8. Transfer the mixture to a greased 9x13-inch casserole dish. Sprinkle mozzarella and Parmesan cheeses evenly on top.
  9. Bake in the preheated oven for 20 minutes or until the cheese is melted and bubbly and the top is golden brown.
  10. Garnish with chopped parsley if desired and serve.

Notes

  • Vegetarian Option: Omit chicken and add more vegetables like spinach, zucchini, or bell peppers.
  • Spicy Kick: Add a pinch of red pepper flakes to the Alfredo sauce for heat.
  • Pasta Alternatives: Use any pasta shape you prefer, including gluten-free pasta.
  • Extra Cheese: Add cream cheese for extra creaminess or cheddar for a different cheesy flavor.
  • Storage: Store leftovers in an airtight container in the fridge for up to 3 days. Reheat in the oven at 350°F for 15–20 minutes or microwave individual portions for 2–3 minutes.
  • Freezing: Assemble and freeze before baking. Thaw overnight in the fridge and bake as directed.
  • Cheese Substitution: Provolone or fontina can replace mozzarella. Pecorino Romano can substitute Parmesan.
