I’ve been going crazy trying to make keto Thanksgiving recipes. Yesterday I made this classic holiday favorite – keto green bean casserole with crispy onions and fresh mushrooms. My husband and I LOVED it! 

One disclaimer though, neither of us love the classic green bean casserole with the cream of mushroom soup. I feel this recipe had a lot more flavor with the different cheeses and creamy sauce. I used wholesome ingredients and no flour or even almond flour.

The topping is a mixture of crushed pork rinds, caramelized onions and Parmesan cheese!  I ate this for dinner by itself and my husband had it as a side dish. I froze the rest so I could have a low carb lunch at the ready. This recipe is definitely good for all holiday meals.

Recipe ingredients I used.

There are two main parts to this holiday side dish; the creamy mushroom sauce for the green beans and the crunchy onion topping.

To make the creamy sauce, the ingredients you need cream cheese, heavy whipping cream and gouda cheese. And for the crunchy onion topping ingredients, you need onions, pork rinds and Parmesan cheese.  

How to make keto green bean casserole!

Step 1: First thing you want to do is caramelize the onions. Heat up an oven proof skillet to medium heat. Add a little butter to a skillet along with thinly sliced onion. You want to cook this for about 10 minutes until they get nice and brown like the photo below.

Step 2: In the meantime cook the green beans in the microwave for 3 minutes.

Step 3: When the onions are done, take them out of the pan and set aside.

Step 4: Using the same pan add more butter along with thinly sliced mushrooms. Cook them for 2-3 minutes until the mushrooms are cooked. Then add in the cream cheese, heavy cream and half of the gouda cheese. Mix this around until the cheeses are melted and everything melds together like the sauce below. You can season with salt and black pepper if you wish but it doesn’t really need it.

Step 5: Now you just toss the green beans in the creamy mushroom sauce in the same oven proof skillet. Or you can mix it together and spoon the green bean mixture into a baking or casserole dish.

Step 6: Crush the pork rinds. I just crushed them in the bag with a rolling pin. However you can also whiz them around in your food processor. When done, mix with the parmesan cheese and fried onions. I wish I could have added more onions but that would have added more carbs to the recipe.

Step 7: Sprinkle the crunchy topping over the green beans and then add the remaining gouda. Bake for about 25-30 minutes until the top is nice and brown. Let cool before serving. (Please scroll down to view and print the recipe card.)

Recipe Tips And Substitutions 

• If you use a oven proof pan like the one above, you won’t have another dish to clean. But you can always spoon the green beans into a baking dish and then add the topping before baking.
• I used gouda cheese in the sauce and topping. You can just add it all to the sauce if you want. You can also use a different cheese. I like gouda shredded cheese because it’s creamy yet stringy but you can try Swiss, gruyere or even sharp cheddar cheese. You could use mozzarella cheese but I don’t feel it has the flavor of these other cheeses.
• For the green beans you can use fresh or frozen beans. I used frozen from Aldi and they were thinner beans. If using thicker beans you might want to cook them for a few more minutes in the microwave. 

Tip: Try pork rind panko crumbs for keto recipes.

If you don’t want to make your own pork rind crumbs you can always buy these Pork Panko breading crumbs on Amazon! I now have them on hand because it’s just more convenient then getting out the food processor and crushing my own.

As much as I love incredible flavor of this keto green bean casserole, I don’t think we will be having it for Thanksgiving. Unfortunately my father in law would prefer the traditional version with cream of mushroom soup but no worries. I have my frozen leftovers for the day after!
