Ingredients

For the Casserole:

  • 4 cups cooked chicken, shredded or diced (rotisserie chicken works great)
  • 4 cups broccoli florets (fresh or frozen)
  • 1½ cups shredded cheddar cheese (or cheese of your choice)
  • 1 cup shredded mozzarella cheese

For the Creamy Sauce:

  • 1 cup heavy cream
  • 4 oz cream cheese, softened
  • ½ cup grated Parmesan cheese
  • 2 teaspoons Dijon mustard
  • 1 teaspoon garlic powder
  • ½ teaspoon onion powder
  • Salt and pepper, to taste
  • ¼ teaspoon crushed red pepper flakes (optional, for a little heat)

Instructions

Step 1: Preheat the Oven

  1. Preheat your oven to 375°F (190°C). Lightly grease a 9×13-inch baking dish with non-stick spray or butter.

Step 2: Prepare the Broccoli

  1. Steam the broccoli until just tender (about 3-5 minutes if fresh, or follow package instructions if frozen).
  2. Drain and set aside.

Step 3: Make the Creamy Sauce

  1. In a saucepan over medium heat, whisk together the heavy cream, cream cheese, and Parmesan cheese until smooth.
  2. Stir in the Dijon mustard, garlic powder, onion powder, salt, pepper, and red pepper flakes, if using. Cook for 2-3 minutes until the sauce is thickened.

Step 4: Assemble the Casserole

  1. Spread the steamed broccoli evenly in the prepared baking dish.
  2. Add the cooked chicken on top of the broccoli.
  3. Pour the creamy sauce over the chicken and broccoli, spreading it evenly.
  4. Sprinkle the shredded cheddar and mozzarella cheese on top.

Step 5: Bake the Casserole

  1. Bake in the preheated oven for 20-25 minutes, or until the cheese is melted and bubbly.
  2. If desired, broil for 1-2 minutes at the end to achieve a golden, crispy top.

Serving Suggestions:

  • Serve hot as a main dish.
  • Pair with a simple green salad or keto-friendly bread for a complete meal.
