Green Bean Casserole

Published March 23, 2026

A classic comfort food side dish featuring tender green beans in a creamy mushroom sauce, topped with crispy fried onions. This beloved casserole is a staple at holiday tables and potlucks.

For a lighter version, substitute half the cream of mushroom soup with low-fat milk or use reduced-fat soup. This casserole can be assembled up to 4 hours ahead and refrigerated before baking; add 5-10 minutes to the baking time if cooking from cold.
