Whether you are prepping meals for the week or feeding your family on a busy night, this creamy chicken alfredo bake always hits the spot.

Simple Ingredients for the Best Chicken Alfredo Bake

I always use freshly grated Parmesan here because it melts into the sauce far more smoothly than the pre-shredded kind. Pro tip: take your cream cheese out of the fridge about 30 minutes before you start so it softens properly and blends without lumps.

• 2 lbs boneless, skinless chicken breasts, cut into bite-sized pieces
• 1 tablespoon olive oil
• 3 cloves garlic, minced (fresh cloves make a noticeable difference in flavor)
• 1 cup heavy cream
• 1 cup grated Parmesan cheese, freshly grated for best results
• 1 cup shredded mozzarella cheese, reserved for topping
• 1/2 cup cream cheese, softened to room temperature
• 1 teaspoon Italian seasoning
• Salt and pepper to taste
• 1/2 cup low sodium chicken broth
• 2 cups broccoli florets, optional but adds great nutrition and color

Pro tip: To boost the protein even further in your high protein chicken alfredo bake, stir one scoop of unflavored protein powder directly into the sauce mixture before baking. It blends in completely and you will not taste it at all.

Step-by-Step Guide to Making This High Protein Chicken Alfredo Bake

I recommend measuring and prepping all your sauce ingredients before you start cooking the chicken. Having everything ready keeps this low carb chicken bake moving quickly and makes the whole process stress-free.

Step 1: Preheat your oven to 375 degrees F (190 degrees C). Grease a 9×13 inch baking dish and set it aside.

Step 2: Heat olive oil in a large skillet over medium-high heat. Add the bite-sized chicken pieces in a single layer, working in batches if needed to avoid crowding. Cook for 5 to 7 minutes, turning once, until the outside is golden brown and the chicken is cooked through with no pink remaining. Add the minced garlic and cook for one more minute. You will smell it immediately.

Step 3: While the chicken finishes cooking, combine heavy cream, Parmesan cheese, softened cream cheese, Italian seasoning, salt, and pepper in a mixing bowl. Stir until smooth. If any cream cheese lumps remain, use a fork to break them up before mixing further.

Step 4: Pour the cream mixture directly over the chicken in the skillet. Add the chicken broth and stir everything together until well combined. The sauce should coat every piece evenly and look thick and creamy. If using broccoli florets, add them now and stir them in.

Step 5: Transfer the entire skillet mixture to your prepared baking dish and spread it into an even layer.

Step 6: Sprinkle shredded mozzarella cheese evenly over the top. This layer creates the golden, bubbly crust that makes this dish so satisfying.

Step 7: Bake for 20 to 25 minutes until the cheese is fully melted, bubbly, and lightly golden. For a crispier top, switch the oven to broil for the last 2 to 3 minutes. Watch it closely during this step.

Step 8: Remove from the oven and let the dish rest for 3 to 5 minutes before serving. This allows the sauce to thicken slightly and makes it much easier to scoop and plate.

Perfect Ways to Serve Your Creamy High Protein Chicken Alfredo Bake

This dish pairs well with light, low carb sides that let the rich and cheesy flavors take center stage. Here are the best sides for high protein chicken alfredo bake.

Zucchini noodles: Spiralized zucchini adds a fresh, slightly crunchy contrast to the creamy sauce and keeps the entire meal low carb from start to finish.

Cauliflower rice: Fluffy cauliflower rice soaks up the alfredo sauce beautifully and adds satisfying bulk without any extra carbohydrates. It works really well for portioned meal prep bowls.

Simple green salad: A crisp salad with cucumber, cherry tomatoes, and a light vinaigrette cuts through the richness and brings a refreshing balance to the plate.

Steamed asparagus: The mild, slightly earthy flavor of asparagus works naturally alongside the garlic and Parmesan in this bake.

Roasted mushrooms: For an extra savory element, roasted mushrooms on the side complement the creamy chicken alfredo flavors and add a satisfying, meaty texture.

How to Store and Reheat Your Chicken Alfredo Bake

This high protein chicken alfredo bake stores really well, which is exactly what makes it one of the best options for weekly meal prep. Store leftovers in an airtight container in the refrigerator for up to 4 days. For longer storage, place cooled portions in a freezer-safe container and freeze for up to 3 months.

When reheating, I recommend warming individual servings in the microwave for 2 to 3 minutes, stirring halfway through. For larger portions, cover the dish and reheat in the oven at 350 degrees F (175 degrees C) for 15 to 20 minutes until heated through. Adding a small splash of chicken broth before reheating keeps the sauce creamy rather than dry or clumped.

Pro tip: Portion this low carb chicken bake into individual meal prep containers right after it cools completely. You will have ready-to-go lunches and dinners for the entire week with zero extra effort on busy days.
