Ingredients

Scale

Chicken and Vegetables

  • 3 boneless, skinless chicken breasts, cut into bite-sized pieces
  • 1 small red onion, chopped
  • 3 cloves garlic, minced

Pasta and Sauce

  • 16 oz (450g) penne pasta
  • 15 oz (425g) jar Alfredo sauce
  • ¼ cup milk

Cheeses

  • 1½ cups shredded mozzarella cheese, divided
  • 1 cup shredded cheddar cheese

Seasoning and Garnish

  • Salt and freshly ground black pepper, to taste
  • Fresh parsley, chopped (optional, for garnish)


Instructions

  1. Preheat the Oven: Preheat your oven to 350°F (175°C) and lightly grease a 9×13-inch casserole dish to prevent sticking.
  2. Cook the Chicken: Heat a skillet over medium heat and cook the bite-sized chicken pieces until they are no longer pink inside, about 5-7 minutes. Season with salt and pepper. Add the chopped onion and minced garlic, cooking for an additional 2-3 minutes until fragrant and softened. Remove the skillet from heat.
  3. Cook the Pasta: Bring a large pot of salted water to a boil. Add the penne pasta and cook according to package instructions until al dente. Drain the pasta well.
  4. Mix the Casserole: In a large mixing bowl, combine the cooked chicken mixture, drained pasta, Alfredo sauce, 1 cup of the shredded mozzarella cheese, and the milk. Stir everything together until evenly mixed.
  5. Assemble & Bake: Spread the combined mixture evenly into the prepared casserole dish. Sprinkle the remaining ½ cup of mozzarella cheese and the shredded cheddar cheese evenly over the top.
  6. Bake: Place the casserole in the preheated oven and bake for 25 minutes, or until the cheese on top is melted, bubbly, and starting to turn golden brown.
  7. Serve: Remove the casserole from the oven and let it cool slightly for a few minutes. Garnish with freshly chopped parsley if desired, and serve warm.

Notes

  • You can substitute penne with other pasta shapes like rigatoni or ziti if preferred.
  • For extra creaminess, add a bit more milk or a splash of heavy cream to the casserole mix.
  • Leftovers can be stored in an airtight container in the refrigerator for up to 3 days and reheated in the oven or microwave.
  • To add some vegetables, consider stirring in cooked broccoli or spinach before baking.
