Ingredients & Variations

GREEN BEANS: Use fresh, frozen, or canned green beans. Be sure to drain and rinse canned green beans. Fresh green beans should be simmered for about 8 minutes before using and frozen green beans can be used as is but will taste better if they are boiled for about 5 minutes first.

PRO TIP: Cook the green beans in chicken broth instead of water for extra savory flavor!

SAUCE: Cream of chicken and cream of mushroom soup are cooked down into a creamy savory sauce and thinned with milk. Stir in some minced garlic or garlic powder, if desired.

CHEESE: A little bit of cheddar cheese adds flavor and makes the sauce extra creamy. Any other shredded cheese like mozzarella or even parmesan will work, too.

TOPPINGS: Green bean casserole always has French fried onions on top to add a savory, crispy crunch! We also like seasoned breadcrumbs, crushed Ritz crackers, or some crunchy bacon bits!

ADD-INS: Delicious add-ins are sliced water chestnuts, slivered almonds, or sliced mushrooms.
