Tips & Variations
- Use cream of mushroom or cream of celery soup to make this casserole vegetarian-friendly.
- Substitute crushed buttery round crackers (such as Ritz) or potato chips for the cornflake topping for a different crunch and flavor.
- Sprinkle sliced green onions on top just before serving to add a pop of color and fresh flavor.
- For extra cheesiness, stir in an additional ½ cup of shredded Cheddar cheese into the mixture.
Storage
Store any leftover casserole in an airtight container in the refrigerator for up to four days. To reheat, warm in the oven to maintain the crispy topping rather than using a microwave, which can make the topping soggy. This casserole can also be frozen—baked or unbaked—for up to three months. Thaw in the refrigerator overnight before reheating or baking.
