What Kind of Green Beans Should I Use?

While canned green beans are the traditional choice for that classic flavor and soft texture, fresh or frozen green beans can give the casserole a bit more snap and vibrant color. If you go the fresh route, blanch them briefly before adding to the mix to ensure they soften just right during baking. Frozen green beans should be thawed and drained to prevent extra moisture in the casserole.

Let the casserole cool completely, then transfer leftovers to an airtight container. Refrigerate for up to 3 days. To reheat, warm it in a 350°F oven for 10-15 minutes or until heated through. To maintain the crispy topping, avoid microwaving if possible. If freezing, assemble without the final onion topping and freeze for up to 2 months; add fresh fried onions when baking.

Frequently Asked Questions

Can I make this casserole ahead of time?
Yes! Assemble everything except the final onion topping and refrigerate for up to 24 hours. Just add the topping and bake when ready to serve.

Can I use cream of chicken or celery instead of mushroom?
You can substitute, but it will change the flavor. Cream of mushroom adds earthy depth that pairs best with green beans.

Is this recipe vegetarian?
Technically yes, but check your soup label. Some cream of mushroom soups use beef or chicken stock.

How can I make this gluten-free?
Use gluten-free cream of mushroom soup and gluten-free fried onions. Several brands offer suitable options.

What’s the best way to add extra flavor?
Try adding shredded cheddar cheese or a pinch of garlic powder to the soup mixture. A sprinkle of parmesan on top also adds a great finishing touch.
