What You’ll Need For Green Bean Casserole

Green Beans

You can use fresh, frozen, or canned green beans.

Canned green beans have a softer texture and require no prep—drain and stir (personal favorite).
Frozen green beans require no cutting and have a tender-crisp texture. They should be boiled for about 5 minutes, and you’ll need to add extra salt.
Fresh green beans have a tender-crisp texture and a fresh flavor. Simmer for 8 minutes.

Other Ingredients

Sauce – Condensed cream of mushroom soup is the base of this casserole and makes it easy to prep. Swap it for a homemade version or any flavor of “cream of” soup such as cream of celery.
Crispy Fried Onions – French’s Crispy Fried Onions adds both flavor and a bit of crunch. A less expensive store brand works great in this recipe.

Garlic: Add minced cloves of garlic cooked in butter or a dash of garlic powder.
Topping: Swap the crispy onions with ¼ cup Panko breadcrumbs mixed with 1 tablespoon each melted butter and parmesan cheese.

Prepare as directed, except store the crispy onion topping in a separate container or sandwich bag. Refrigerate for up to 48 hours.
Remove the casserole from the refrigerator at least 30 minutes before baking.
Sprinkle the onions on top, bake as directed, adding up to 10 minutes of extra cooking time if needed.

How To freeze

If you’re taking this dish to a gathering, prepare everything as directed and skip the last 10 minutes of baking. Cover with aluminum foil, wrap it in a towel to insulate the heat, and place it in a cooler or insulated bag.

Preheat the oven to 350°F.
If using fresh or frozen green beans, boil just until tender crisp (see notes).
In a large bowl, combine green beans with soup, milk, soy sauce, pepper, salt, 1 cup of crispy onions, and cheese if using (see notes). Transfer to a 2qt or 8×8 baking dish.
Bake uncovered for 30 to 35 minutes or bubbly.
Remove from oven and stir. Top with remaining onions and return to oven for an additional 10 minutes or until golden.

Green beans: Canned, fresh, or frozen beans work in this recipe. In place of frozen beans, you can use either of the following:

drain 2 (14 ½ ounces each) cans of cut green beans
1 ½ pounds fresh green beans, trimmed and simmered for about 7-8 minutes

Optional additions:

1 ½ cups shredded cheddar cheese mixed into the sauce (favorite!)
fried mushrooms, onions, garlic, and/or shallots

Cheese: If adding cheese, you can mix the cheese in with the soup for a cheesy sauce or sprinkle it on top after stirring. I prefer to mix it into the sauce.
Slow cooker: Prep the green bean casserole as above and cook in a 4qt slow cooker on low for about 2-3 hours. Once heated through, turn the slow cooker to warm. If your slow cooker is larger than 4qt, double the recipe.
Make ahead: This casserole can be made up to 48 hours ahead of time—store the topping on the side until baking. Remove the casserole from the fridge for at least 30 minutes before baking. You may need to add 10 minutes of extra cooking time.
Leftovers: Leftovers can be stored in an airtight container in the refrigerator for 2-3 days.
