Ingredients (Serves 4)
- 4 boneless, skinless chicken breasts
- 1 tablespoon olive oil
- 1 small onion, chopped
- 1 cup cauliflower florets (fresh or frozen)
- 1 cup broccoli florets (fresh or frozen)
- 1 cup shredded mozzarella cheese
- ½ cup grated Parmesan cheese
- ½ cup heavy cream
- ¼ cup cream cheese
- ½ teaspoon garlic powder
- ½ teaspoon onion powder
- ¼ teaspoon paprika

How to Make Easy Low Carb Chicken Casserole
Step 1: Prepare the Chicken
- Preheat your oven to 375°F (190°C).
- Season the chicken breasts with salt, pepper, garlic powder, onion powder, and paprika.
- In a large skillet, heat 1 tablespoon olive oil over medium heat.
- Sear the chicken breasts for about 4-5 minutes per side until golden brown and almost cooked through. Remove from the skillet and set aside. The chicken will finish cooking in the casserole.
Step 2: Prepare the Vegetables
- In the same skillet, add the chopped onion, cauliflower, and broccoli. Sauté for about 4-5 minutes until slightly softened.
- Add a little salt and pepper to taste, then remove from heat.
Step 3: Make the Creamy Sauce
- In a small saucepan over medium heat, combine the heavy cream and cream cheese. Stir until the cream cheese is fully melted and the mixture is smooth.
- Add in the mozzarella and Parmesan cheese, stirring until the sauce is thick and creamy.
- Taste and adjust the seasoning with garlic powder, onion powder, salt, and pepper.
Step 4: Assemble the Casserole
- In a large baking dish, spread the sautéed vegetables evenly on the bottom.
- Place the seared chicken breasts on top of the vegetables.
- Pour the creamy cheese sauce over the chicken and vegetables, making sure everything is coated well.
Step 5: Bake
- Cover the casserole with aluminum foil and bake for about 25-30 minutes, or until the chicken reaches an internal temperature of 165°F (74°C).
- Remove the foil, and bake for an additional 5-10 minutes to allow the cheese to become bubbly and golden.
Step 6: Garnish & Serve
- Once baked, remove from the oven and garnish with fresh parsley (optional).
- Serve hot and enjoy!
