Step-by-Step Guide: How to Make Chicken Alfredo Casserole

Step 1: Preheat and Prep

Preheat oven to 375°F (190°C). Lightly grease a 9×13-inch baking dish with olive oil or butter.

Step 2: Cook Pasta or Low-Carb Base

Cook pasta according to package instructions if using. If making keto-friendly, roast spaghetti squash or prepare zucchini noodles instead.

Step 3: Mix Chicken and Sauce

In a large bowl, combine cooked chicken, Alfredo sauce, garlic powder (if using), salt, and pepper. Stir until chicken is fully coated. If sauce is too thick, add heavy cream to thin it slightly.

Step 4: Assemble

Spread cooked pasta (or low-carb substitute) in the bottom of the baking dish. Pour chicken and sauce mixture evenly over the base. Sprinkle mozzarella and parmesan evenly over the top.

Step 5: Bake

Bake uncovered for 20–25 minutes, or until cheese is melted, bubbly, and golden brown.

Step 6: Garnish and Serve

Remove from oven, let rest for 5 minutes, and garnish with fresh parsley before serving.
