FREQUENTLY ASKED QUESTIONS:

What kind of cheese is best to use?

Some people like cheese in their Green Bean Casserole and some don’t. We like to use a mixture or parmesan and cheddar for ours. We also use freshly grated as it melts and incorporates a bit better, but store-bought grated (or finely shredded) cheese can also be used. You can play around with your cheese preferences but we have found that this combination works nicely.

Can I use frozen green beans?

Yes you can. I like to defrost them before adding them to the slow cooker, but adding them frozen will work too it will just add a short bit of time to cooking.

Can other soups be used?

If you are not a fan of cream of mushroom soup you really can use any cream of soup that you’d like. Some others that we have used are cream of chicken soup, cream of celery, cream of potato etc. Feel free to use what you like best. Or if you don’t like cream soups at all, check out my recipe for Green Bean Casserole with no cream soups.

Can I bake this?

Yes! If you would rather bake this recipe in the oven and have the space, you can absolutely do that. Prepare casserole as directed but in a larger baking pan, about 9×13-inch and bake in your oven for about 35-40 minutes. Add the remaining french fried onions and bake for another 10 minutes until golden.

How do I store leftovers?

This can be stored in an airtight container in the refrigerator where it should keep for up to 2-3 days. You can reheat your leftovers in the microwave until heated through.

  1. 5 stars
    This recipe has become a family favorite in my house. I love that it is made in the crockpot. It’s definitely a step up from the original recipe.

  2. Thanks for this recipe with exact amounts. I don’t own a crockpot. Isn’t there a way to bake this in the oven. Thanks !
    Happy Thanksgiving Y’all’s !!!

    1. I haven’t tested this particular recipe in the oven. I specifically designed it to be made in the crock pot. I suppose you could start with 25 minutes in a 350F degree oven. Put the rest of the French fried onions on top then bake for another 5 minutes until they’ve browned a little.

  3. I’m actually getting tired of green bean casserole. Never thought I’d say that! But this one looks good. I’ll have to try it!
