Green Beans: Fresh, frozen, or canned all work in this recipe. Be sure to drain and thoroughly rinse canned green beans before using.

Sauce: Cream of mushroom soup is the standard, but you can use cream of celery or chicken if that’s what you have. Add softened cream cheese in Step 2 for a richer sauce, if you like.

French-Fried Onions: Crispy, crunchy, and essential to green bean casserole, but you can also use crushed Ritz crackers or even a package of seasoned stuffing.

Variations: Bulk up green bean casserole with sliced mushrooms, water chestnuts, or any leftover veggies in the fridge! Bacon bits add smoky flavor and crunch too!
