Creamy Chicken Alfredo Bake with Bubbly Mozzarella Tips, FAQ & printable recipe

Tips for success

For an even richer garlic flavor, you can roast a whole head of garlic beforehand and squeeze the sweet, caramelized cloves directly into the warm cream sauce.

Additionally, reserving about a half-cup of the pasta cooking water before draining is a great culinary habit. If your alfredo sauce becomes too thick during assembly, a small splash of this starchy water will easily restore its smooth, velvety consistency.

Always allow the baked casserole to rest on the counter for at least ten minutes before serving. Slicing into the hot bake immediately will cause the creamy sauce to run to the bottom of the dish, leaving the top portions dry.

Giving it a brief resting period allows the starches and proteins to stabilize, ensuring a clean, perfect square slice with beautiful, stretchy cheese pulls.

Variations

• Broccoli Chicken Alfredo Bake: Add two cups of steamed broccoli florets to the pasta and chicken mixture before tossing with the sauce for extra color and texture.
• Spicy Bacon Alfredo Bake: Stir in half a cup of crumbled cooked bacon and a pinch of red pepper flakes into the garlic cream sauce for a smoky, spicy kick.

Storage and make-ahead

Fridge

Store leftover pasta bake in an airtight container in the refrigerator for up to 3 to 4 days, cooling it within 2 hours of cooking.

Freezer

Freeze tightly wrapped in plastic wrap and aluminum foil for up to 2 months. Thaw completely in the refrigerator before reheating.

Reheat

Cover with foil and bake at 350°F (175°C) for 15 to 20 minutes, or microwave individual portions with a splash of milk to keep the sauce creamy.

Cool any leftovers completely at room temperature for no more than two hours before storing. Place the leftovers in an airtight container and store them in the refrigerator. Properly stored, the chicken alfredo bake will remain fresh and delicious for up to three to four days, making it an excellent option for quick weekday lunches.

This entire casserole can be assembled up to 24 hours in advance. Prepare the pasta, chicken, and sauce, assemble them in the baking dish, and top with the mozzarella. Cover the dish tightly with plastic wrap or aluminum foil and store it in the refrigerator. When ready to eat, bake it covered at 375°F (190°C) for 25 minutes, then uncover and broil.

Serving ideas

Serve this decadent pasta bake hot, garnished with a generous sprinkle of freshly chopped parsley and an extra dusting of grated parmesan cheese.

To balance the rich, creamy flavors of the alfredo sauce, pair each portion with a crisp, acidic side dish. A simple Caesar salad with a tangy lemon dressing or a garden salad tossed in a light vinaigrette works beautifully.

For a complete Italian-American feast, serve the bake alongside warm, toasted garlic bread or soft rosemary focaccia. The crusty bread is perfect for scooping up any extra garlic cream sauce left on the plate.

Steamed green vegetables, such as broccoli florets or roasted asparagus spears, also make excellent side dishes that cut through the richness of the cheese.

Creamy Chicken Alfredo Bake with Bubbly Mozzarella

Prep 20 minCook 25 minRest 10 minTotal 55 minServes 6

Ingredients

• 12 oz penne pasta
• 1 lb boneless skinless chicken breasts
• 4 cloves garlic, minced
• 2 cups heavy cream
• 1 cup grated parmesan cheese
• 2 cups shredded mozzarella cheese
• 2 tbsp fresh parsley, chopped

Instructions

1. Bring a large pot of salted water to a boil. Add the penne pasta and cook for 8 minutes, or until just slightly under al dente. Drain the pasta and set it aside in a large mixing bowl.
2. Heat a tablespoon of olive oil in a large skillet over medium-high heat. Season the chicken breasts with salt and pepper. Cook the chicken for 6 to 8 minutes per side, ensuring the thickest part reaches a safe internal temperature of 165°F (74°C). Transfer the chicken to a board, let it rest, and shred it.
3. In a large skillet over medium heat, pour in the heavy cream and add the minced garlic. Bring to a gentle simmer, then whisk in the grated parmesan cheese until fully melted and the sauce becomes velvety and smooth.
4. Preheat the oven to 375°F (190°C). Pour the velvety garlic cream sauce over the cooked penne pasta and shredded chicken in the large mixing bowl. Toss everything together gently until the pasta and chicken are evenly coated in the rich alfredo sauce.
5. Transfer the pasta mixture into a 9x13-inch baking dish. Sprinkle the shredded mozzarella cheese evenly over the top. Bake for 15 minutes, then turn on the broiler for 2 to 3 minutes until the mozzarella is bubbling with golden-brown spots. Garnish with chopped fresh parsley before serving.
