Ingredients

Scale

Chicken Mixture

  • 2 cups cooked chicken, shredded or diced
  • 1 tbsp olive oil
  • 1 clove garlic, minced
  • 1/2 tsp salt
  • 1/4 tsp black pepper
  • 1/4 tsp Italian seasoning

Pasta and Sauce

  • 12 oz pasta (penne or rotini recommended)
  • 2 cups Alfredo sauce (store-bought or homemade)
  • 1 cup frozen peas (optional)

Cheese Topping

  • 1 cup mozzarella cheese, shredded
  • 1/2 cup Parmesan cheese, grated

Garnish

  • 1/4 cup fresh parsley, chopped (optional garnish)


Instructions

  1. Preheat the Oven: Begin by preheating your oven to 375°F (190°C). Grease a 9×13-inch baking dish to prevent sticking and ensure easy cleanup.
  2. Cook the Pasta: Boil the pasta according to package instructions until al dente. Once cooked, drain well and set aside to cool slightly.
  3. Sauté the Garlic: Heat the olive oil in a skillet over medium heat. Add the minced garlic and sauté for about 1 minute until fragrant, being careful not to burn it.
  4. Cook the Chicken: Add the cooked chicken, salt, black pepper, and Italian seasoning to the skillet with the garlic. Cook for 2 minutes to warm up and allow the seasonings to meld with the chicken.
  5. Combine Ingredients: In a large mixing bowl, combine the cooked pasta, Alfredo sauce, sautéed chicken mixture, and frozen peas if using. Stir everything together until evenly mixed.
  6. Assemble the Casserole: Transfer the combined mixture into the prepared baking dish. Evenly sprinkle the shredded mozzarella and grated Parmesan cheeses over the top.
  7. Bake: Place the baking dish in the preheated oven and bake for 25 to 30 minutes, or until the cheese is melted, bubbly, and lightly golden.
  8. Serve: Remove the casserole from the oven and allow it to cool for 5 minutes. Garnish with freshly chopped parsley if desired, then serve warm.

Notes

  • You can substitute rotini or penne pasta with any short pasta shape you prefer.
  • For a healthier version, use a light Alfredo sauce or homemade low-fat alternative.
  • Adding frozen peas is optional but adds a nice color and slight sweetness.
  • Leftovers can be stored in an airtight container in the refrigerator for up to 3 days.
  • Reheat gently in the microwave or oven to maintain creaminess and texture.
