How to Make Keto Chicken Alfredo Casserole

Ingredients

  • 1 lb boneless, skinless chicken breasts, cut into bite-sized pieces
  • 1 cup heavy cream (room temperature)
  • 1 cup Parmesan cheese (freshly grated)
  • 2 cups broccoli florets (cut into bite-sized pieces)
  • 1 tsp garlic powder (or substitute with fresh minced garlic)
  • Salt and pepper (to taste)
  • Butter or high-heat oil (for greasing the baking dish)

Directions

  1. Preheat the oven to 375°F (190°C) and grease a 9×13-inch casserole dish.
  2. Cook chicken: Season the chicken with salt and pepper. In a skillet over medium-high heat, cook until no longer pink, about 5–7 minutes. Remove from the pan and set aside.
  3. Blanch broccoli: Boil the broccoli florets for 2 minutes, drain, and rinse them with cold water to stop cooking.
  4. Make Alfredo sauce: In the same skillet, bring the heavy cream to a simmer over medium-low heat. Gradually whisk in the Parmesan until melted. Add garlic powder, salt, and pepper. Stir until slightly thickened, about 3–5 minutes.
  5. Assemble casserole: Layer the chicken and broccoli in the prepared dish. Pour the sauce over the top, making sure all ingredients are coated.
  6. Bake for 15–20 minutes, or until bubbling and golden on top. If you want a more browned top, you can broil it for an additional 2 minutes.
  7. Let the casserole rest for 5 minutes before serving.

How to Serve Keto Chicken Alfredo Casserole

You can serve this casserole hot, straight from the oven. It pairs well with a simple side salad or some low-carb bread if you like. Each serving offers a hearty portion of protein and vegetables, making it filling and satisfying.

To store leftovers, let the casserole cool completely. Then, cover it tightly with plastic wrap or transfer it to an airtight container. It can be kept in the refrigerator for up to 3-4 days. If you want to freeze it, store it in a freezer-friendly container for up to 2-3 months. Reheat in the oven or microwave until warmed through.
