Why this Recipe is Best

When it comes to holidays, we all have our favorite side dishes.

Growing up, Green Bean Casserole is not the dish I chose. When you’re presented with a bowl of mashed potatoes or a big scoop of sweet potato casserole, the green beans get overlooked.

As an adult, Green Bean casserole with its creamy mushroom soup and crispy fried onions is now one of the first scoops of food on my plate.

If you’re like me, and avoided this classic recipe for years, give it another go this holiday!

Ingredients Notes

Green Beans: I choose canned green beans for this classic side dish. Whether you opt for regular green beans or the french style cut beans is your preference.

You can use frozen or fresh beans, but be sure to cook them to tender first before adding to the casserole.

Milk: The heavier the milk the creamier the casserole. I buy a small whole milk for the holidays, to use when making mashed potatoes, so it’s perfect with this green bean casserole too!

2% milk will also yield great results!

Mushroom Soup: Having tried numerous brands and “off” brands of canned mushroom soup, I am now pretty picky and only choose Campbell’s.

I love the thickness and flavor, as well as the color (yes, if you’ve ever bought other brands they don’t look the same. You can make homemade cream of mushroom soup with my quick recipe below, but given the option, I will always choose Campbell’s.

French’s Crispy Fried Onions: Some people have referred to this dish as French’s Green Bean Casserole because the crispy fried onions really do steal the show.

You’ll know this is true because watch people scoop it out of the casserole, they always try to take as much of the topping as possible!

Comments & Reviews

  1. This is pretty much the green bean casserole recipe on the back of the durkee French fried onion ring crisps that you add to green bean casserole and been around for 40 years. Your recipe is a copy cat of that and not original it seems.

  2. While we did enjoy it, it seems a little heavy on the black pepper. We like black pepper, but I think next time I’ll use about half as much. Otherwise delicious.

    1. I was just thinking the same thing. I’m going to make it tonight but then add the topping just before serving tomorrow. Hope it works out. Lol

  3. Wondering if I can used asparagus and cream of asparagus soup oppose to green beans and cream of mushroom soup.
    I’m thinking since the asparagus are very slender, I would just have to French cut them and not precook them.
    What do you think?

  4. Sorry, this is the grossest,unheathiest dish I can think of! Why not just sauté some onions, and put on top of some cooked fresh beans? Not hard and a heck of a lot better.

    1. Because some recipes are enjoyed for generations, and this Green Bean Casserole is something our family has eaten for years and years and we love it. Feel free to saute fresh green beans, but please no need to come here and judge others.

  5. If making the cream of mushroom grin scratch, Do you still need the whole milk??

    Others asked, but I didn’t see an answer. Please let us know! Thank you!!

  6. For the mushroom soup can I make it ahead of time and store it. If so would I store it in the freezer or refrigerator so that I can use the next day

  7. Sorry, to clarify-I don’t have a circular baking dish like the one shown above…is there an alternative baking dish you would recommend?

  8. I’ve always considered the Soy Sauce the “magic” ingredient. If you could taste-test the same recipe, one without soy sauce, and one with, you would be amazed at the difference.

  9. You can’t beat the classic recipes but what I really love is how you gave the option to make homemade cream of mushroom soup! Perfect!

  10. Dear Amiee
