Can you make Campbell’s Green Bean Casserole ahead of time?

Yes! You can assemble this up to two days in advance, just stop and cover it before baking. Then cook and top with onions right before serving.

However, it comes together so fast and so easy (no chopping or extra steps needed) that I usually just make it right before we need to eat it.

Can you freeze Campbell’s Green Bean Casserole?

Yes! Freezing will work best if you have not cooked the casserole. Mix ingredients together, do not bake, place in freezer safe containers and save until you are ready to bake and top with fried onions.

If you have already cooked the dish, you can still freeze the leftovers, but the fried onions will get soggy. 

Some people scrape off the fried onions before freezing to stop them from getting soggy. Other people leave them on and just add new friend onions before reheating it again. 

Whatever you decide, you will need new fried onions to keep that crispy topping after this dish has been frozen.

Why do you use frozen green beans?

In Campbell’s original green bean casserole recipe, they call for canned green beans. But I like the taste of frozen green beans better.

Frozen green beans are picked at peak freshness, partially cooked, instantly cooled, and then frozen to keep them perfectly fresh and crisp any time of the year.

They give a better crunch and a truer green bean flavor than canned green beans that are canned with other liquids.

Frozen produce is always perfectly fresh and partially cooked. It’s also faster to use. I prefer my version of Campbell’s green bean casserole recipe with frozen green beans.

Could you use fresh green beans in Campbell’s Green Bean Casserole? 

Yes. But you will need to wash, trim the ends, and pre-cook the beans, before you can use them in the casserole dish.

And honestly, sometimes fresh produce gets lost in my fridge and goes past its freshest period before I can use it, so using frozen green beans guarantees them to be perfectly fresh when I need them.

Should frozen green beans be thawed before cooking?

No need to thaw the frozen green beans. I toss them in frozen and let the simmering water in the pan do all the work. What is this? The amount of time you simmer the frozen green beans will determine how crispy or soft they will turn out.

Can you substitute frozen green beans for canned?

GREEN BEANS For this recipe, you can use fresh, frozen, or canned. Canned will provide a softer casserole while fresh or frozen add have a bit more texture (and need more salt added to the recipe). If using fresh or frozen, cook your beans until tender-crisp, about 5 minutes for frozen and 8 minutes for fresh.

Can I substitute frozen green beans for fresh green beans?

You can substitute frozen green beans in place of fresh in most recipes; however the frozen beans tend to get soggy compared to fresh green beans. If the recipe is being baked you can use the beans still frozen. If you're going to toss them in a salad then let them thaw naturally.

How do you keep frozen green beans from being mushy?

Blanching green beans before freezing helps them to retain that beautiful green color and crisp texture when you go to enjoy them. Skipping this step might result in your beans having a mushy texture once defrosted.
