It’s not Thanksgiving without a classic green bean casserole on the table, amirite? 

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 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.

How to make Keto Green Bean Casserole From Scratch:

What’s In Green Bean Casserole:

In a healthy, made from scratch green bean casserole, you only need a few simple fresh ingredients:

  1. Fresh green beans
  2. Fresh Button Mushrooms
  3. Onion
  4. Garlic
  5. Chicken Stock
  6. Cream Cheese
  7. 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.

This is how to do it:

visual step by step instructions on 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. (Photo 1)
  2. While waiting on the green beans to boil, sauté onions and mushrooms plus the spices, until soft. (Photo 2 and 3)
  3. The chicken/vegetable stock and cream cheese goes in next! Stir until the cream cheese is melted and everything is well combined. (Photo 4 and 5)
  4. Once everything is warm and bubbly, add the cooked green beans and mix well. (Photo 6)
  5. Scrape everything into a casserole dish and top with grated cheddar. (Photo 7)
  6. Pop it into oven until the cheese is melted and bubbly. (Photo 8)

For an optional yummy topping, I like to slice onions and coat them lightly in a bit of coconut 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 onions won’t fry super crispy, but it does definitely add very good flavor to the dish as a whole.

Healthy Low Carb 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.

Can Green Bean Casserole Be Made Ahead?

Yes! The beauty of this recipe is that is can be made ahead and baked when you’re ready to eat it.

I generally complete all the steps except the “sliding it into the oven” part, and instead covered it carefully with foil and refrigerate right away. It will be good for at least 3 days in the fridge before baking.

Then, when you’re ready to eat it, slide it into a 350F/180C oven and bake for approximately 20 minutes – checking that it’s heated all the way through. Afterwards, crank up the heat and leave until the cheese is golden and bubbly.

Can Green Bean Casserole Be Frozen?

This recipe can be made ahead and frozen for up to two weeks, if properly sealed. Cover the casserole dish with foil and then a layer of cling film.

When you’re ready to eat, remove the cling film and slide into a preheated (350F/180C) oven for 20-30 minutes until heated through.

Followed by a few minutes under the broiler until the cheese is melted and bubbly.

    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:)

    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.

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

    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!
