Ingredients

Scale
  • 1 pound pasta (penne, fettuccine, or rotini)
  • 1 tablespoon olive oil
  • 1 pound boneless, skinless chicken breasts or thighs, cooked and shredded (rotisserie chicken works well)
  • 1 cup chopped broccoli florets (optional)
  • 1 cup chopped bell peppers (optional)
  • 1 cup sliced mushrooms (optional)
  • 1 (16 ounce) jar Alfredo sauce
  • 1 cup shredded mozzarella cheese
  • 1/2 cup grated Parmesan cheese
  • Salt and black pepper to taste

Instructions

  1. Preheat your oven to 375°F (190°C). Cook pasta according to package directions until al dente. Drain well.
  2. While the pasta cooks, heat olive oil in a large skillet over medium heat. Add chicken and any desired vegetables (broccoli, bell peppers, mushrooms) and cook until vegetables are tender-crisp.
  3. In a large bowl, combine the cooked pasta, shredded chicken, cooked vegetables, Alfredo sauce, mozzarella cheese, and Parmesan cheese. Season with salt and pepper to taste.
  4. Pour the mixture into a 9×13 inch baking dish.
  5. Bake for 20-25 minutes, or until the casserole is heated through and the cheese is melted and bubbly.
  6. Let stand for a few minutes before serving.

Notes

  • For a make-ahead option, assemble the casserole, cover, and refrigerate for up to 24 hours before baking. You may need to add a few extra minutes to the baking time.
  • This casserole freezes well. Cool completely, cover tightly, and freeze for up to 3 months. Thaw overnight in the refrigerator and bake as directed.
  • Feel free to add other vegetables like spinach, peas, or zucchini.
  • Consider this a great option for meal planning.
