For a lighter version, you can substitute the heavy cream with half-and-half or milk. If you prefer a bit of spice, use hot Italian sausage or add a pinch of red pepper flakes to the sauce. For a vegetarian option, omit the sausage and add more mushrooms or some spinach for extra greens. You can also experiment with different types of cheese, such as Gruyere or cheddar, for a unique flavor twist.
