Keto Green Bean Casserole

If you’ve ever had a “traditional” green bean casserole with the cream of mushroom soup and crispy onion bits, this isn’t that. When creating this low-carb green bean casserole I wanted a casserole that was a little more “elevated”.

I took inspiration from an old favorite recipe of mine from Food Wishes that was a “french onion soup green bean casserole” with of course the star being the caramelized onions.

I decided to pair the flavorful caramelized onions with provolone cheese and a keto-friendly cream sauce which is super simple to make! Even though I use provolone cheese, any white cheese that you like will work well!

The result of the onions, creamy sauce, cheese, and green beans layered in a casserole dish and baked until bubbly is pure perfection! If you bring this dish with you to Thanksgiving or really any potluck year-round, you’ll be asked to bring it every time!

My favorite part about this low-carb green bean casserole (besides eating it!) is how simple it is to make! There are just a few components that come together to make this perfect holiday side dish.

First, you’ll cook the onions down until they are caramelized and test them aside. Next, you’ll want to make the keto cream sauce.

If you’re a good multitasker, you can make the sauce while the onions are caramelizing.

Just make sure you keep a close eye on your onions so they don’t burn. The keto cream sauce is as simple as bringing the unsalted butter and heavy cream to a simmer, adding some parmesan cheese and spices, and cooking until the sauce is reduced by one-third.

Then you’ll blanch the green beans by adding them to a pot of boiling water for 4 minutes. You’ll know they’re ready when the green beans become vibrant green.

Once the green beans are blanched, you’ll strain them, toss them in salt and pepper. and add them to the bottom of your baking dish.

On top of the green beans, pour the keto cream sauce and spread the caramelized onions on top evenly. Top that off with the shredded provolone cheese and it’s ready to bake!

When the cheese is browned and bubbly, around 20 to 25 minutes, your casserole is done and ready to be served and enjoyed!
