So, the problem is that most traditional green bean casserole recipes found on the internet uses pre-made ingredients like cream of mushroom soup, or frozen beans.

Even if you weren’t looking for a wholesome low carb and keto-friendly green bean casserole recipe, it’s always better to use fresh ingredients –  fresh green beans, fresh mushrooms. You just can’t compare it to the flavor of a casserole made with pre-made ingredients.

Making a fresh Keto Green Bean Casserole recipe from scratch is by far the best way to go. Your family will definitely appreciate absolutely delicious taste experience of wholesome ingredients.

What sets our green bean casserole recipe apart from the rest is the fact that it is a healthy recipe, using only whole ingredients. That’s the secret!

Ingredients to Make Keto Green Bean Casserole:

  • Fresh green beans
  • Fresh Button Mushrooms
  • Onion
  • Garlic
  • Chicken Stock
  • Cream Cheese
  • Grated Cheddar

And then, a couple of spices, salt and pepper.

If you judge this recipe by the flavor of the dish alone, you’ll never know that this is a healthy, fresh recipe. It stands up to any of the best classic green bean recipes out there!

Even though you’re cooking from scratch and using only fresh ingredients, this recipe is ridiculously quick and easy.

How to Make Keto Green Bean Casserole:

  1. Start by boiling fresh green beans in well salted water until fork tender. It takes about 10 minutes. Drain and set aside when done.
  2. While waiting on the green beans to boil, sauté onions and mushrooms plus the spices, until soft.
  3. The chicken/vegetable stock and cream cheese goes in next! Stir until the cream cheese is melted and everything is well combined. Can’t beat that creaminess!
  4. Once everything is warm and bubbly, add the cooked green beans and mix well.
  5. Scrape the mixture into a baking dish and top with grated cheddar.
  6. Pop it into oven until the cheese is melted and bubbly.

For an optional yummy topping, I like to slice onions and coat them lightly in a bit of coconut flour or almond flour. I then shallow fry them in oil (in a pan) until they are golden. It’s really quick to do and adds another element of deliciousness.

The fried onions won’t be super crispy, but it does definitely add very good flavor to the dish as a whole. If you want something crispy on top, you can also go for pork rinds!

Healthy Keto Green Bean Casserole Variations:

I feel that a classic green bean casserole is best, but sometimes a little variation doesn’t hurt. 

So, here some ideas of ways to spruce things up a little bit:

  1. Bacon. Probably the most common variation is the addition of bacon. It does add a delicious spin to the recipe!
  2. Red Bell Pepper. Adding red bell pepper to the recipe not only gives a satisfying pop of color but the flavor of red bell pepper really complements the dish in a unique way.
  3. Almonds. An interesting addition to green bean casserole is adding chopped almonds, or almond slivers. Green beans and almonds are a classic duo, and it gives a satisfying crush to an otherwise monotonously textured dish.  

Of course, this is an amazingly delicious green bean casserole and it doesn’t need to be thanksgiving for you to enjoy this with any dinner. It’s even great for weeknights – yes, it’s that easy to make!

    This was delicious! I didn’t have fresh mushrooms so I just used 2 cans of mushrooms and it tasted wonderful! Will definitely be making this again!

    I was told to bring “something Keto” for me to eat if I didn’t like her menu for a family gathering! When I asked what the menu was there seemed to be a veggie gap. This casserole not only filled that gap, but people went back for seconds! I’m so glad I doubled the recipe! Yes, no canned green beans or mushrooms for this dish. So good.

  3. 5 stars
    Yummmm! I made this for Easter because several family members are on the keto diet. I tweaked it a little bit by adding a teaspoon of Worcestershire, only one onion, two cloves of garlic and topped it with bacon. It was fabulous. I’m eating the leftovers right now.!!

  4. 5 stars
    Amazing! My husband and I both agreed this is better than the classic version. I’d prefer this even if we weren’t doing keto. And it’s one of those rare recipes I didn’t feel like I needed to change anything.

    1. This was delicious! It’s the first time I am growing green beans this year and I have a ton of them. Usually, I just saute them with butter, salt and pepper and they turn out pretty good. This recipe, however; kicks it up a notch with the cream cheese, cheddar, onion,mushrooms (Iused can) and the 1/4 tsp of nutmeg! Thank you so much for sharing 🥰

  5. I just wanted to say that I made this for a previous Thanksgiving, and it was SO good that I’m coming back to follow the recipe again for this year’s keto Thanksgiving feast! Thank you for sharing such a delicious recipe! 🙂

  6. This was a HUGE hit in my house. So excited about doing Keto when I find recipes this delicious. Definitely filling and helps me stay on track. Will be adding this to my favorite recipes.

  7. 5 stars
    OMG this recipe was amazing. I did end up using no salt added canned beans bc I am lazy and this turned out perfect. My mom who hates “keto” foods and was super skeptical, thought this was better than the original! I also coated onion and shallot slices in coconut flour and avocado oil and air fried for about 20 mins and sprinkled on top of the casserole. Soooo so good. Wanted to be sure to leave a review so that everyone can make this. 😋

  8. Inin the directions it says to boil green beans in salty water & reserve the salt water. I don’t seem to see where it mentions what for? What am I missing?

    1. It says “drain water and set aside”. That means drain water down the sink and set aside the green beans.

  9. Love this recipe I make it with bacon and peppers. My whole family loves it. I made it last year and will again stih year too!

    1. 5 stars
      This recipe is delicious. Will definitely be a keeper. I cut my mushrooms up into smaller pieces but that was the only different thing I did.

  10. 5 stars
    This is an excellent recipe! It is definitely a keeper! Because I had so much fresh Romano green beans from the garden, I tripled the recipe and it was delicious!

  11. 5 stars
    This recipe is amazing! I added a little cayenne to it because my family likes spicy and they were looking for more… have to double the recipe next time. THANKS!

    1. Hi Kat! It will probably be okay. I would just drain them well and then add them in at the same point of the recipe.

    1. Hi Cheryl – we’ve updated the post, but not the recipe itself. Not sure why it didn’t turn out the same for you, I’m sorry about that!

    1. Hi Mary!:) I have this recipe to make 6 servings, but they are good sized portions. If you serve this with a meal that has one or two other side dishes, it could serve up to 8 even. Hope that helps!

  12. I added bacon and nutritional yeast plus slivered almonds, and believe it or not, I was out of mushrooms so I left them out and added extra onions! I also had some feta cheese that I needed to use, so I used feta plus cream cheese in sauce. The casserole did not last, and was totally devoured by the end of the night! Thank you!

    1. Hi Yelba:) Glad you enjoyed the recipe and was able to tweak it to your tastes – Sounds delicious with your changes! Thank you for the feedback.

  13. I’m a very reluctant (bad!) cook and was rushing around and REALLY didn’t want to make this but because the recipe keeps reiterating that it’s easy, I felt like I had to give it a go, to take to a dinner party. I’m so glad I did – it truly was so easy and so delicious, easily the star of the dinner party! I couldn’t get enough of it! 🙂

    1. Hi Megan! Yes, you can certainly swap the chicken stock for vegetable stock. There is the case of the cream cheese though, so if you’re okay with dairy – then yes, swapping the stock will be just fine:)

        Thank you so much for sharing this recipe. It’s my first keto casserole and I’m impressed 😊! I modified with a little bit of bacon bits (homemade) and used both cheddar and mozzarella cheese. This recipe is definitely a keeper!

  15. 5 stars
    I put crumbled bacon on mine! So good. Thanks for this awesome recipe. I’m not a green bean casserole fan, but making it without cans of soup made it completely homemade.

    1. Ahh crumbled bacon sounds like a great variation to the original recipe! Glad you enjoyed it 🙂 Homemade is best!

      1. Hi Marie. Yes, this can be made ahead. I have given details on making ahead and freezing this recipe in the post if you want more details.

  16. 5 stars
    Super good! I didn’t have cheddar cheese and used mozzarella instead. My husband loved it! I will add chicken to it next time for a complete meal in one pan. Thanks for the recipe! Can’t wait to try more of your recipes.

      1. Yes, you are correct. They are also known as yellow onions. I will add that to the recipe card. Thank you!

      2. 5 stars
        This is insanely delicious! The only changes I made was to use only one onion because that’s all I had, and to replace the chicken stock with 1/2 teaspoon of organic chicken flavored Better Than Bullion – no water. Also I saved on cleanup by using a bag of fresh microwavable string beans and cut them after they cooked and cooled. Thank you for this amazing recipe! I love it when I can cook something keto for myself that everyone can enjoy! Empty casserole dish here tonight!!
