Ingredients You’ll Need

For the Casserole:

• 2 pounds of chicken breasts
• 15 oz refrigerated cheese tortellini
• 2 cups shredded provolone and mozzarella cheese blend
• ¼ cup Italian Panko bread crumbs
• 4 tbsp unsalted butter
• 3 cloves minced garlic
• 3 tbsp SPG blend (salt, pepper, garlic)
• 1 tbsp olive oil
• Garnish: Fresh parsley

For the Homemade Alfredo Sauce:

• 4 tbsp unsalted butter
• 3 cloves minced garlic
• 1 cup heavy cream
• ½ cup whole milk
• 1 cup grated Parmesan cheese
• 2 tbsp all-purpose flour
• 1 tsp salt
• ½ tsp black pepper

How to Make Grilled Chicken Alfredo Casserole

Step 1: Prepare and Grill the Chicken

Start by slicing the chicken breasts in half through the middle, making thinner, even pieces that cook faster and more evenly. Drizzle each piece with a little bit of olive oil, then season with the SPG blend on both sides.

Grill the chicken at 350°F until the internal temperature reaches 165°F. The grilled flavor adds depth to the creamy sauce later. You can also use rotisserie chicken as a time-saving swap if desired.

Step 2: Cook the Pasta

While the chicken grills, cook the tortellini according to package directions until it’s al dente pasta.

Be sure to reserve a small amount of pasta water—this will help your sauce cling to the cooked pasta perfectly. Drain and set aside.

Step 3: Make the Homemade Alfredo Sauce

In a large skillet over medium heat, melt butter and sauté the minced garlic for one minute.

Sprinkle in the flour and whisk until a smooth paste forms. Gradually add heavy cream, milk, and Parmesan, whisking until it becomes a smooth, creamy Alfredo sauce.

For best results, let the sauce simmer gently on medium-low heat, stirring occasionally. If it thickens too much, thin it out with a splash of chicken stock, chicken broth, or the reserved pasta water.

Step 4: Combine Everything

Add the chopped grilled chicken and cooked tortellini into the skillet. Mix everything thoroughly until coated in the Alfredo sauce. This mixture should look irresistibly creamy and rich.

Transfer the mixture to a greased baking dish and top with shredded provolone, mozzarella, and Italian Panko bread crumbs.

Step 5: Bake and Broil to Perfection

Place your chicken Alfredo pasta bake under the broiler on low for about 4–5 minutes, or until the cheese melts and turns golden brown.

You can also bake chicken Alfredo casserole at 350°F for 20–25 minutes if you prefer a more melted, bubbly top layer.

Step 6: Serve and Enjoy

Sprinkle with freshly chopped parsley before serving. This dish pairs beautifully with garlic bread or a crisp green salad to balance out the richness.

For leftovers, store them in an airtight container in the refrigerator for up to 3 days. The flavors often deepen as they sit, making it even more delicious the next day.

Tips for the Best Grilled Chicken Alfredo Casserole

• Use al dente pasta: Slightly undercook your pasta so it doesn’t get mushy when baked.
• Add a touch of pasta water: It helps the sauce stick to the pasta perfectly.
• Shred your own cheese: Freshly shredded cheese melts smoother and gives you that stringy, irresistible texture.
• Try different pastas: If you don’t have tortellini, use penne pasta or fettuccine noodles for a twist.
• Customize the seasoning: Add Italian seasoning or crushed red pepper for extra flavor.
