Keto Green Bean Casserole [+VIDEO]

This Keto Green Bean Casserole recipe with fresh green beans is easy & delicious. It’s perfect if you want classic green bean casserole for holidays like Christmas and Thanksgiving minus the carbs. It uses a homemade keto cream of mushroom soup, and a pork-free crunchy cheese topping for those who want to enjoy this side dish without pork rinds. Plus, get tips on how to make low-carb green bean casserole with canned or frozen green beans.

Why Make This:

Here are a few reasons why you should make this delicious green bean casserole for a holiday meal like Thanksgiving dinner, or whenever you want:

• Easy to make and includes a video tutorial
• Uses a homemade keto cream of mushroom soup, which comes with wholesome ingredients.
• Keto-friendly, gluten-free, and low-carb alternative to a holiday favorite because it skips out on crispy fried onions and thickeners like cornstarch that are in traditional green bean casserole recipes.
• Pork-rind free topping for those who want the crunchy topping minus the carbs and pork
• Perfect for the holiday season, or any day you and you’re whole family are craving these flavors.

Ingredients Needed:

• Fresh Green Beans: I purchased these trimmed and washed to save time
• Keto Cream of Mushroom Soup: this recipe includes the steps to make keto cream of mushroom soup with cremini mushrooms, sliced onions, broth, spices, and heavy whipping cream (or heavy cream)
• Mozzarella Cheese: I used the low-moisture, shredded kind

Crunchy Topping:

All green bean casseroles need a crunchy topping. A more traditional recipe would include fried, crispy onions (french fried onions).

But, the carbs in those can add up quickly because two tablespoons have 3g net carbs.

So, I’m including a low-carb and keto-friendly alternative. For the crunchy topping, you’ll need:

• Crunchy Cheese: I’m using the parmesan variety. You can get plain or any flavor. One of my favorite flavors is the Oven Baked Cheese with Black Summer Truffle. I got this in-store from Trader Joe’s for a few bucks, but it’s available on Amazon as well.
• Spices: you likely have these in your pantry – dried parsley, onion powder, and garlic powder. I’m omitting salt and pepper here because the crunchy cheese adds a salty flavor.
• Roasted Pecans: these add an additional texture and flavor

How to Make Keto Green Bean Casserole:

Making this recipe is super easy. And, the best way to learn how to make it is to watch the video tutorial in this post.

The recipe is split into four main parts:

1. Make keto cream of mushroom soup: You’ll notice that I sauté the vegetables and then add all of the other soup ingredients.
2. Steam and add fresh green beans to the soup: I personally get my green beans in a microwavable bag to save time. But, you could also use a pot and steamer insert. If you’re unsure how to do this, steps 3 to 5 of how to steam fresh green beans will be a helpful resource.
3. Prepare the crunchy and crispy topping: You can add all of the ingredients for the crunchy parmesan cheese topping to a food processor or blender. Then, pulse a few times to incorporate the ingredients.
4. Layer & Bake: you’re mostly doing this step to allow the cheeses to melt and the greens beans and mushroom soup more time to meld together. Of course, the last layer should be some crunchy toppings on top of the casserole.

Top Cooking FAQs & Tips

• Hold the salt and pepper: you might be wondering why this recipe does not include salt and pepper. I skip them because the herb seasoning includes pepper and the cheese topping as well as the broth paste work to season the dish.
• Use the bake time to brown the cheese: the green bean casserole is mostly ready to enjoy before baking. So, you can save time, by ensuring that your string beans are tender enough for you before putting the casserole mixture in the baking dish. For me, once the cheese has a beautiful golden brown color, the casserole is ready!
• Swap the crunchy cheese with pork rinds: if you want to have this dish with pork rinds, you can swap crunchy cheese with an equal amount of pork rind breading.

How to Store This Casserole Dish

If you have any leftovers of this green bean recipe, the best way to store them is in an airtight container or in a dish covered with plastic wrap for next time (up to 3-4 days).

Tips for using canned green beans

I used fresh green beans when testing this recipe. If you use canned green beans, you should try to get a variety without added salt. You should also rinse the green beans several times to try to get as much of the added ingredients off of them before adding them to the soup.

Tips for using frozen green beans

Another option, which I imagine would work better than canned green beans is frozen green beans. Simply follow the steps to steam them (frozen green beans usually come in microwavable bags) and add them to the soup as shown in the video.

Make keto green bean casserole with canned cream of mushroom soup

I prefer the homemade cream of mushroom soup (which comes with fresh mushrooms) that is included in the recipe. That’s because it tastes better and you can control all of the ingredients in your creamy mushroom sauce. If you use canned cream of mushroom soup, then you’ll have to add chicken broth base and salt to taste.

Premade Keto Cream of Mushroom Soup

This recipe includes steps for making keto cream of mushroom soup. But, you can make the soup ahead of time if you wish.

When you’re ready to make the casserole, heat the cream of mushroom soup in a large pan (or large skillet) and add the steamed green beans for your creamy sauce.

You’d be skipping steps one to three in the directions section called “for the keto cream of mushroom soup and green beans”.
