Ingredients Needed for Green Bean Casserole

You’ll be using all the classic ingredinets in this dish!

Green beans.

You can use frozen, fresh, or canned.

I personally prefer canned because it delivers a less crunchy bite.

I’m all about texture, so I go for the canned.

In other recipes, I prefer fresh green beans.

You can also use classic cut green beans instead of french style.

These are my favorite canned green beans my grandmother got me hooked on years ago!

Mushroom soup.

I did use canned in this recipe, but since this recipe was photographed, I have converted to homemade mushroom soup, homemade cream of chicken soup, and even homemade cream of celery soup.

I cannot BELIEVE how easy it is to make!

Plus, it’s packed with flavor, ready in minutes, and super simple!

Until I put my own recipe on the blog, you can find a homemade recipe here for cream of mushroom soup.

The one I make is extremely similar!

French fried onions.

Side story…our family lived in Cambodia for 12 years and could not get french fried onions.

So, I can tell you, it tastes amazing if you make your own french fried onion rings.

If you want to make the ultimate version of this recipe, then make homemade french fried onion rings.

But if you make the entire holiday meal and need shortcuts, by all means follow the recipe below because it uses the store bought ones…which are still yummy!

Optional: Shredded Cheddar Cheese

Sharp cheddar or Colby cheese is perfect to add some extra creaminess to this recipe.

We typically add 1 1/2 cups when we want a cheesy version of this classic!

Prepare as directed, but don’t add the crunchy onion topping.
