Feel free to get creative! You can use different cheeses, like Monterey Jack or Gruyere. Add some cooked bacon or crispy fried onions for extra texture and flavor. If you don’t have sour cream, plain Greek yogurt is a great substitute. Don't overcook the onions. Make it ahead! For a spicier kick, add a pinch of red pepper flakes to the sauce. Leftovers can be stored in an airtight container in the refrigerator for up to 3 days. Reheat gently in the microwave or oven.
