Storage/Reheating

Store leftover Green Bean Casserole in an airtight container in the refrigerator for up to 4 days.

To reheat, place the casserole in a 350°F (175°C) oven for 15–20 minutes until warmed through. If reheating individual portions, the microwave works well, though the topping may not remain as crisp.

For best results, store extra fried onions separately and add them during reheating to maintain their crunch.

FAQs
