Holly’s Recipe Highlights

I love green bean casserole, it reminds me of holidays from my childhood. This version is great because…

  • Fast prep: It needs just 5 minutes of prep—it’s the easiest side dish ever.
  • Versatile: It can be made with fresh, frozen, or canned green beans.
  • Make ahead: Make this casserole a few days in advance and bake before serving (see notes).
  • Serve anytime: Perfect for a holiday meal or alongside a Sunday supper like meatloaf.

Ingredient Notes

  • Use fresh, frozen, or canned green beans:
    • Canned green beans have a softer texture and require no prep—drain and stir (my personal favorite).
    • Frozen green beans require no cutting and have a tender-crisp texture. They should be boiled for about 3-5 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.
  • Sauce: Condensed cream of mushroom soup is the base of this casserole and makes it easy to prep. Use any flavor of “cream of” soup, such as cream of celery.
  • Crispy Fried Onions: French’s Crispy Fried Onions adds both flavor and crunch.

Variations

  • Cheese: I love to add cheddar cheese to the green bean casserole sauce. Try other favorite cheeses.
  • From Scratch: Swap out the soup for mushroom cream sauce and replace the onions with fried shallots.
  • Garlic: Add minced garlic cloves cooked in butter or ½ teaspoon of garlic powder.
  • Topping: Swap the crispy onions with ¼ cup of Panko breadcrumbs mixed with 1 tablespoon each of melted butter and Parmesan cheese.

Notes

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 (14.5 ounce 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 it with the soup for a cheesy sauce or sprinkle it on top after stirring. I prefer to mix it into the sauce.
Make ahead: This casserole can be prepped 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.

  1. Are there other types of creamed soup that can be used for this recipe such as cream of chick or cream of celery? I’m planning to make it for my sister who doesn’t like mushrooms.

  2. Thank you so much for this recipe. I’ve made this multiple times in the past few years and no matter if I use fresh, canned or frozen green beans it always turns out delicious. It is now a classic in my house.
    I came back to print it and noticed a funny error in your notes.

    Make Ahead: This casserole can be made up to 48 hours ahead of time. Remove the casserole from the OVEN for at least 30 minutes before baking.

    I think you meant from the ”Refrigerator” ;-)
    In any case I could hug your for your wonderful recipes and website. You’ve saved many a dinner and multiple embarrassments. lol ♥

  3. If using canned green beans, is it 2 cans = 4 cups frozen? So for serving 12 it would be 6 cans drained and rinsed beans?

    1. You will need two 14.5 oz cans which makes 8 servings. For 12 servings you’d need to make 1.5x the recipe so 3 cans (since you’d need 1 ½ cans of mushroom soup, it might be easier to double the recipe and have leftovers). You can also change the serving sizes on the print page.

  4. This looks great! Just want to confirm, is the soup condensed cream of mushroom? Or just the regular cream of mushroom?

    1. You can make it a day ahead. I would suggest keeping the onions for the top separate and adding them right before baking.

    1. Hi Katie, we love it both ways but the cheese is just a fun way to switch it up and add a sharp cheesy flavor and creamy texture to the recipe. You will have to let us know what you think of it!

  5. Definitely a keeper! I’ve tried many over the years and this is the best, hands down. I removed all the others from the Copy Me That app. Can’t figure out how to share on Facebook though….definitely think the shredded cheese made a nice addition to this old classic. Thanks so much!5 stars

  6. Excellent, I used cream of asparagus soup and it was delicious. Thanks for all your fabulous recipes. Merry Christmas5 stars

    1. Hi Jane, our canned soup is sold in 10 ½ ounce cans so for this recipe we use one can of cream of mushroom soup.

    2. Jane,
      Unfortunately you may be the one confused. Cream of Mushroom Soup (The condensed version, which is specified in this recipe) is sold in 10.5 oz.

      What soup are you buying?

  7. I just made this for my first time. Not sure how many bags of frozen beans I needed I used 2 1lb bags of beans.
    So.letsbsee how this comes out.

  8. Is it okay if I cook the casserole the day before, and then on the day of put the onions on top and cook it for 10 minutes? And if that is okay, how long should I cook it to re-heat it before putting the onions on?

    1. Hi Valerie, I would take it out of the fridge while you preheat the oven and then bake until bubbly. Top with the crispy fried onions and bake for an additional 10 mins or so.

  9. I found this recipe just in time for Thanksgiving. I can’t wait to try it. I will be doubling the recipe and wonder how much extra time I should allow to bake? Thanks!

    1. To double this recipe I would suggest a 9×13 pan and increasing the baking time by about 10-25 minutes. The mixture should be hot in the middle when you stir it before adding the onions for the last 10 minutes. Happy Thanksgiving.

  10. If I am making a double batch could I use one can of cream of chicken. And one cream of mushroom? Or should they both be the same flavor? Thank you for sharing!
