Why You Need This Keto Green Bean Casserole On Your Table

- Easy. A simple pour and cook recipe made with the help of your Instant Pot.

I don't know about you, but I absolutely LOVE green bean casserole. It's an absolute must-have side dish in my home for the holiday season, with no exceptions.
The only thing is, it's not known for being particularly low carb. And knowing that I just couldn't possibly live without it, I decided I needed to whip up a delicious Keto Green Bean Casserole Recipe, quick and in a hurry.
And let me tell you, this Low Carb Green Bean Casserole is an absolute hit! There's just something so deliciously comforting about this dish.
From the creaminess of the mushrooms to the tender bite of the green beans, to the crispiness of the topping, I love every bit of it. And this Keto Green Bean Casserole is so good that it could make a convert out of even the most anti-green bean friend or family member you have.
The big secret to making this recipe so good? Not using tons and tons of canned, processed ingredients. Instead of cream of mushroom soup, I opt to use fresh mushrooms, cream cheese, and half and half in its place.
I also use fresh green beans instead of canned. The result is a much more flavorful and fresh-tasting casserole. But don't just take my word for it, this Keto Green Bean Casserole really must be experienced to be truly appreciated!
And did I mention that it's just as easy to make as any other green bean casserole recipe? That's thanks to one of my favorite kitchen appliances, the ever-dependable Instant Pot.
Seriously, you can make this dish in a fraction of the time in the Instant Pot and all you really have to do is dump the ingredients in the pot and mix it once. It really is that easy!
Are Green Beans Acceptable On A Keto Diet?
One cup of green beans has about 10 grams of carbs. However, 4 of those are from dietary fiber, meaning that there are only 6 net carbs per cup of green beans.
That fact, along with proper portion control (as with any food), makes green beans a perfectly keto-friendly veggie.
Can I Eat Fried Onions On Keto?
Traditionally a green bean casserole is covered in crunchy, french fried onions. These onions are breaded and are regrettably high in carbs.
I've found the best low carb alternative for this Keto Green Bean Casserole to be toasted almonds. The almonds give that crunch that you'd expect from a good green bean casserole and they lend a flavor to them as well!
How Many Carbs Does Green Bean Casserole Have?
Traditional Green Bean Casserole is extremely high in carbs from the variety of canned soups and the mountain of french fried onions on top.
This low carb green bean casserole only has 8 net carbs per serving. This is achieved by replacing the canned soups with cream cheese and substituting (at least in part) the fried onions with crunchy slivered almonds.
Is Cream Of Mushroom Keto Friendly?
If you use my homemade mushroom soup recipe, it absolutely is!
Skip the premade cans of mushroom soup to cut the carbs even more for this tasty side dish.

How Long Does It Last?
If you're using this for a holiday side, chances are you won't have any leftovers. However, if you're making it for a weeknight side dish or for meal prep, you will want to eat this within 3 days of preparing it.
The mushroom soup can make the green beans too soggy to enjoy after sitting in your fridge for too long.

Absolutely delicious!!! But not much to look at - the beans turned to mush and the sauce never thickened, so it looked more like soupy mush than anything. But the flavor was AMAZING!!!!
I'm giving it 3 stars because the instructions inlcude putting butter into the Instant Pot but butter is not included in the list of ingredients...so how much butter should be included, if at all?
WOW! So much flavor for such simple ingredients! A great substitute for a pasta side dish.
Doesn’t look like this blogger responds to comments but I’ll give it a shot anyway lol...can this be made ahead and heated in the oven next day?
I am allergic to almonds and don’t like pork rinds. Any alternatives to add crunch to this?
Step 1 mentions adding butter, but I don't see butter in the ingredients list. How much butter?
I also wondered about how much butter... I used 3 Tbs which worked fine. The sauce didn't thicken as much as I would have liked, but I didn't want the green beans to cook longer. Perhaps remove them when reducing the sauce? It was delicious anyway!
Sounds yummy and I would like to make this, only concern is the 5g of sugar. Where is the 5 g of sugar come from?

Hi Urvashi, you have the cream cheese cubes in two places in the recipe - Step 2 and Step 4. Which is it? I would think Step 4 is correct. Thanks, I'm not usually a green bean casserole gal but this sounds delightful.
I was confused by this too. Just want mine to turn out how this delish pic looks.
