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

The problem is that most classic 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 fresh goodness.

What sets this green bean casserole recipe apart from the rest is the fact that it is a healthy recipe, using only whole ingredients.

How to make Healthy Fresh Low Carb Keto Green Bean Casserole From Scratch:

BUT – 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. I’m looking at you, French’s and Betty Crocker!

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:

Start by boiling fresh green beans in well salted water until fork tender. While waiting on the green beans, sauté onions and mushrooms until nicely caramelized.

For an optional yummy topping, I like to slice onions and coat them lightly in a bit of coconut flour. I then fry them in oil 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 your basic green bean casserole is the best green bean casserole, 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.

    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.

    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!
