Chef’s Notes

  • For extra color and flavor, stir in about 1 cup of frozen peas before baking.
  • Swap the Cheddar for Monterey Jack or Colby Jack cheese for a different flavor profile.
  • Crushed buttery crackers or seasoned breadcrumbs can be used in place of the fried onions for a crunchy topping.
  • Store leftovers in an airtight container in the refrigerator for up to 3 days. Reheat individual portions in the microwave or warm larger portions in the oven.
  • This casserole also freezes well before baking. Thaw overnight in the refrigerator before cooking as directed.
