Low Carb Green Bean Casserole

Are you looking for a Low Carb Green Bean Casserole Recipe? Are you thinking you might have to give up this traditional American comfort food now that you are eating low carb or keto?

One of the all-time favorite holiday side dishes for American holidays is the classic Green Bean Casserole. History has it that it was first created in 1955 and promoted by the Campbells Soup Company, and it featured their Cream of Mushroom Soup.

Over the years, there have been revisions and variations of the original. Still, the consistent ingredients have been the original Cream of Mushroom Soup, green beans, and the dried onion rings. My family always added a thick layer of grated cheddar cheese on top too.

No matter which version you are familiar with, the cream of mushroom soup and the dried onion rings are too high in carbs to fit into either a low carb or a keto diet.

This Low Carb Green Bean Casserole recipe, while different than the original, will provide much the same flavor and texture. This recipe trades fat for some of the carbs, which makes it fitting for either a low carb or keto meal, and it definitely fits into the “comfort food” category.

Preheat your oven to 350 degrees.

Begin by preparing your green beans. If using canned green beans, drain the beans, and set aside. Either regular cut or french cut green beans will work.

If using fresh or frozen green beans, begin by cooking them on a stovetop in a medium saucepan with about 1/4 cup of water added. Cook until tender, then drain and set aside.


Preparing the Sauce

Add the dried onions and soy sauce to the cheese mixture. Stir and simmer for a few minutes, until the mixture is well blended and begins to thicken.

Bake in the oven for about 45 minutes. The timing is pretty flexible. You want the inside to be bubbling hot and the cheese to be melted and starting to brown around the edges.

Low Carb Green Bean Casserole for Family Gatherings

Having received my official diagnosis shortly before Christmas, I didn’t have much time to figure out what I could and could not eat. It was a challenge, to say the least.

I basically got through that first Christmas with my meter and a meal that included turkey, raw vegetables, and cheese. No potatoes, no dinner rolls, no dessert, no stuffing, and NO GREEN BEAN CASSEROLE. I decided then and there that the next year would be different.

And it was. I and others have tried and tweaked and experimented until we landed here.
