How to Store and Reheat Green Bean Casserole Like a Pro

Leftover Green Bean Casserole is basically a gift from the food gods. Don’t let those extras go to waste!

Store in an airtight container in the fridge for up to 3 days. The flavors actually deepen, making tomorrow’s lunch even tastier.

When reheating, cover your casserole loosely with foil and use a low oven (around 350°F) for 15–20 minutes. This keeps the onions crunchy and the inside creamy—no sogginess allowed.

If you’re reheating single servings, a quick spin in the microwave works. Just add fresh fried onions on top for that classic crunch.
