Chicken Alfredo Casserole Recipe
Introduction
Chicken Alfredo Casserole is a comforting and creamy baked dish that combines tender chicken, penne pasta, and rich Alfredo sauce topped with melted cheeses. It’s perfect for a family dinner or when you want a satisfying meal with minimal fuss.

Ingredients
- 3 skinless, boneless chicken breast halves
- 1 (8 ounce) package penne pasta
- ½ (16 ounce) jar Alfredo sauce
- 1 ½ cups shredded mozzarella cheese, divided
- ¼ cup milk
- 1 tablespoon onion powder
- 1 tablespoon garlic powder
- 1 cup shredded Cheddar cheese
Instructions
- Step 1: Preheat the oven to 350 degrees F (175 degrees C).
- Step 2: Place the chicken breasts into a pot and cover with water. Bring to a boil over high heat, then reduce heat and simmer until the chicken is no longer pink in the center and juices run clear, about 15 minutes. Drain and cut into bite-sized pieces.
- Step 3: Meanwhile, bring a large pot of lightly salted water to a boil. Add the penne pasta and cook until tender but firm to the bite, about 11 minutes. Drain well.
- Step 4: In a large bowl, combine the cooked chicken, cooked pasta, Alfredo sauce, ½ cup of mozzarella cheese, milk, onion powder, and garlic powder. Mix well to combine.
- Step 5: Pour the mixture into a 1 ½-quart casserole dish. Sprinkle the remaining mozzarella and the Cheddar cheese evenly over the top.
- Step 6: Bake in the preheated oven until the cheese is melted and bubbly, about 25 minutes. Remove from oven and let sit for a few minutes before serving.
Tips & Variations
- For added flavor, try using cooked bacon bits or sautéed mushrooms mixed in with the chicken and pasta.
- Substitute penne with other pasta shapes like rigatoni or rotini for a different texture.
- Use homemade Alfredo sauce for a fresher taste if you have extra time.
- Sprinkle some fresh chopped parsley or basil on top before serving for a bright finish.
Storage
Store any leftovers in an airtight container in the refrigerator for up to 3 days. Reheat in the oven at 350 degrees F until warmed through or microwave in short bursts, stirring occasionally. Avoid reheating multiple times to maintain the best texture.
