Ingredients

To make this Keto Chicken Alfredo Casserole, you’ll need:

• Protein and Veggies:
  • 2 cups cooked, shredded chicken (rotisserie chicken works great)
  • 2 cups broccoli florets (or your favorite low-carb vegetable)
• For the Alfredo Sauce:
  • 1 ½ cups heavy cream
  • 4 ounces cream cheese, softened
  • 1 cup grated Parmesan cheese
  • 2 cloves garlic, minced
  • 1 tablespoon olive oil or butter
  • 1 teaspoon Italian seasoning
  • ½ teaspoon salt
  • ¼ teaspoon black pepper
• For the Topping:
  • 1 ½ cups shredded mozzarella cheese
  • Optional: Fresh parsley, chopped, for garnish

Instructions

1. Prep the Oven and Ingredients:

• Preheat your oven to 375°F (190°C).
• Steam or blanch the broccoli florets until tender but still crisp (about 3-4 minutes) and set aside.
• If using uncooked chicken, cook it in a skillet with olive oil or butter, then shred or chop into bite-sized pieces.

2. Make the Alfredo Sauce:

• Heat a medium saucepan over medium heat. Add olive oil or butter and sauté the minced garlic until fragrant (about 1 minute).
• Reduce the heat to low, then stir in the cream cheese, whisking until smooth.
• Gradually add the heavy cream, stirring constantly to prevent clumping.
• Mix in ¾ cup of the Parmesan cheese, Italian seasoning, salt, and pepper. Cook until the sauce is thickened and creamy (about 3-5 minutes).

3. Assemble the Casserole:

• In a large mixing bowl, combine the cooked chicken, steamed broccoli, and Alfredo sauce. Stir until evenly coated.
• Transfer the mixture to a greased 9×13-inch baking dish.

4. Add the Cheese and Bake:

• Sprinkle the shredded mozzarella and the remaining Parmesan cheese evenly over the top.
• Bake for 20-25 minutes, or until the cheese is bubbly and golden brown.

5. Rest and Serve:

• Remove the casserole from the oven and let it rest for 5 minutes.
• Garnish with fresh parsley, if desired, and serve warm.

This casserole is perfect for meal prepping or serving fresh out of the oven for a cozy, satisfying dinner.

You can customize this recipe by swapping broccoli for cauliflower, spinach, or zucchini to create a different flavor profile.
