Keto chicken alfredo casserole is a delicious and healthy take on a classic comfort food dish. Its savory homemade alfredo sauce is thickened with cream cheese and heavy whipping cream, forming a creamy base that complements the flavor of savory cooked chicken and the accompanying broccoli and cauliflower. The addition of cheese on top adds an extra creamy texture that ties this cheesy casserole together. It’s an indulgent yet healthy meal that can satisfy both low-carb dieters and those who prefer more traditional fare.
Preheat the oven to 350 degrees Fahrenheit (177 degrees Celsius).
Cut the chicken into cubes and season with salt and pepper. Heat a large skillet over medium heat, add a small amount of butter or oil and cook the chicken cubes until they are lightly browned. Once cooked, remove the chicken from the pan and set aside.
Deglaze the pan with chicken broth to remove any stuck-on bits from the chicken.
To make the alfredo sauce, add butter, cream cheese, parmesan cheese, heavy cream, half of the mozzarella cheese, and garlic powder to the pan.
Whisk until everything is combined and melted together. Season the sauce to taste with salt and black pepper.
Layer the broccoli, cauliflower, and cooked chicken together in an oven-safe dish.
Pour the alfredo sauce over the top and sprinkle with the remaining mozzarella cheese.
Bake for 40-50 minutes, until the cheese is melted and golden brown and the vegetables have softened.
Garnish with fresh parsley (optional) and serve hot! Enjoy!
