So I need to start by saying that I am not a fan of green beans. At all. It was never really part of the Korean diet growing up so I don’t think I even tried a single green bean until my early twenties.

And after trying that single green bean, I swore green beans off forever. That is, until I had this green bean casserole, smothered in the creamiest mushroom sauce and topped with extra crunchy friend onions.

Now I may have just picked off all of the fried onions and mushrooms I could find but still, I think I managed to sneak in a couple of green beans here in there!

    Your recipes that you share made my Christmas dinner so very easy this year. For Christmas dinner I made your slow cooker Maple Brown Sugar Ham, Parmesan crusted scalloped potatoes and your Easy green bean casserole, and your Glazed carrots. My Christmas dinner was a total hit thanks to you. You weren’t here personally, but your recipes graced my table. Thank you for all the wonderful recipes you post. I have tried a lot of them, and they never fail me. Have a wonderful New Year also sending Best Wishes.

  2. This formula is soooo acceptable! I made it a year ago for Thanksgiving and it was a success! I am making it again this year. My sister flippantly asked me not to bring it since a year ago she made herself wiped out eating such an extensive amount it. It is so rich and delightful, it’s difficult to simply eat a typically estimated bit of it. A debt of gratitude is in order for sharing this and adding another dish to our vacation menu!

  3. This recipe is soooo good! I made it last year for Thanksgiving and it was a big hit! I am making it again this sunday

    This is my favorite green bean casserole recipe! I’ve made it for several years now and it’s always a hit. I have a question though! My office is having a friendsgiving and I offered to make this, completely forgetting that we don’t have an oven at the office! Do you think I can make it in a slow cooker???

    This recipe is soooo good! I made it last year for Thanksgiving and it was a big hit! I am making it again this year. My sister jokingly asked me not to bring it because last year she made herself sick eating so much of it. It is so rich and delicious, it’s hard to just eat a normal sized portion of it. Thanks for sharing this and adding a new dish to our holiday menu!

    Can I make this a few days ahead of time? Minus the topping, of course, and then bake the day of?

  7. We’re spending Thanksgiving with my MIL who is unfortunately dairy intolerant. Is there an alternative to heavy cream in this recipe?

  8. Have made this several times for Thanksgiving and Easter to  happy satisfied family members! We add bacon or bacon bits to ours. Today I’m making for dinner but I’m out of thyme so I’m subbing with poultry seasoning. Thanks for a great recipe!

  9. This was AMAZING! Best green bean casserole I’ve ever had or made. And no cans of anything! Well, except the french fried onions. My 3yo loved it! I added a half cup of shredded cheddar, just because I love cheese, but made it otherwise exactly as stated – so much flavor, the green beans were cooked exactly right and so creamy! Thank you so much! 🙂

  10. So disappointed in this dish! Bland. I did the dishes and saw that everyone who tried it left most on their plates.

  11. Hi!
    Thinking of making this for my family this thanksgiving. You’ve mentioned that it’s best served right away.  So I’m wondering, if I have the beans/mushrooms cooked all the way up until baking a couple hours in advance, and just add the onions and throw in the oven just before dinner, do you think that will that work?  

  12. Might you list how many servings?

  13. Do you think I could make any portion of this the day before?  Thanks for your help!  By the way – I have made MANY of your recipes and they are always fantastic.  Thanks for taking the time to share them.

    • I actually have not tried making this ahead of time myself so I cannot really answer with certainty. As always, please use your best judgment.

  14. I made this for Thanksgiving and it was a HIT! I absolutely loved it!!! I topped mine with the onions as well as bacon crumbles. I also used frozen green beans. I cant wait to make it again! I’ve made about 30 of your recipes and look on here almost daily for something new to make =) THANK YOU!

  15. In the photos there appears to be onions cooked with the mushrooms, but I don’t see it in the recipe.

  16. It looks like everyone wants me to have green bean casserole. It’s every where I go. I really am not complaining. It looks amazing. How could anything be wrong with this amazing dish?!
    Time to add it to the menu for the first time!

  17. can you use frozen green beans?

  18. I’ve never eaten much green bean casserole, because in my experience, they were always made with mushy green beans. I HATE mushy green beans, but I like haricot vert! Will give this a whirl sometime!

  19. Love your recipes I have tried! I love green bean casserole and have been looking for a way to make it fancier. Have you tried it with frozen or canned green beans or is only good with fresh?

  20. Yum! I AM a huge green bean lover…especially with those fried onions. Mmmm 🙂

  21. Can you double this recipe and it still come out the same as the original recipe?

  22. Lactose intolerant. Has anyone made this with coconut milk, almond milk?

  23. MmmMmMmMm green bean casserole is one of my favorite parts of Thanksgiving!! Yum! I think I will save this, though, and make it for dinner one night that’s NOT turkey day because why not, right? Yum yum!

  24. I absolutely LOVE all the mushrooms in your green bean casserole… it looks absolutely mouth-watering divine! I’ll definitely be making this for Thanksgiving, as I LOVE anything that is loaded with mushrooms!

  25. I love green beans..we grow them in our greenhouse every year just so we have plenty fresh!They grow hanging down the sides and top on lovely vines. I even love them just sautéed in olive oil…also zucchinis are great that way. So healthy and deliciously simple!! I will try this on Thanksgiving along with your creamed corn recipe…both look wonderful!

  26. Chungah;
    Oh, you’ve hit the nail on the head this time! This will blow my family away next week. None of the same old boring out-of-a-can casserole! Ha! Well, you know . . .

    Thank you,


  27. Green Bean Casserole was totally NO a part of Thanksgiving growing up in Canada…and then I came down to The States and my taste buds fell off my head when I tried it! Loving the creamy mushrooms with the crunchy topping! Pinned!

  28. Green beans have never been a favourite of mine. I’m going to try this recipe even though it may be a little heavy on the calories. I guess that’s what makes it so yummy. Lol I think I’ll just do it all in a cast iron fry pan and transfer that to the oven.

  29. Ah I love crispy fried onions, SO good, and this dish looks fantastic 😀 x

  30. This looks amazing and I love that there’s mushrooms in it….mmmm! I would eat this and only this if I could for Thanksgiving!

    And not liking green beans? Ok now you HAVE to come down to SD because there is this place that serves fried green beans with a wasabi aeoli that basically is like…the best.thing.ever. I will do extra cardio just to indulge in those things. Possibly my favorite bar snack in all of SD! 🙂
