Ingredient Substitutions: You can substitute the heavy cream with half-and-half for a lighter version, or use cashew cream for a dairy-free option. Optional Variations: Add cooked chicken, shrimp, or vegetables like bell peppers and spinach to make it a complete meal. Storage or Reheating Tips: Store leftovers in an airtight container in the refrigerator for up to 3 days. Reheat gently on the stovetop, adding a splash of cream or milk to loosen the sauce as needed.
