Low Carb Instant Pot Green Bean Casserole Recipe

Low Carb Instant Pot Green Bean Casserole Recipe is a great side dish for a holiday meal (it’s a Thanksgiving classic!), roast chicken dinner, or even grilled steak.

Low Carb Instant Pot Green Bean Casserole Recipe Individual Bowl

We had fun remaking this classic holiday side dish into a low carb version of itself. Because our version features sauteed mushrooms, onion, and garlic in a rich and creamy sauce (instead of canned soup, like the original recipe), it’s even tastier than the original.

You won’t even miss the carbs in our Low Carb Instant Pot Green Bean Casserole Recipe!

And another bonus, this recipe can be partially made up to three days ahead (because we know how hectic cooking can be on a holiday). Not to worry if you don’t have an Instant Pot because we also give instructions on how to make this green bean casserole without an Instant Pot.

Holiday Green Bean Casserole

For most of us, it’s not a holiday meal without the green bean casserole on the table! We all know what it is…in its most basic form, this casserole consists of green beans in a creamy mushroom sauce topped with crunchy fried onion bits.

It’s delicious, at least it is the first day while it’s piping hot and served alongside roast turkey. But have you noticed that it after the first meal, no one seems to really enjoy this casserole as leftovers?

I’ll come out and say it, it just doesn’t (usually) reheat well. Our version uses just one pound of green beans, so hopefully you’ll have fewer leftovers!

And also, the other issue with classic holiday green bean casserole is the high carb count. You know we had to fix that! With a couple of low carb substitutions, this side dish is still rich and satisfying, but much lower in carbs.

Carbs in Holiday Green Bean Casserole

According to McCormick, one serving of French’s Green Bean Casserole has the following nutrition information:

  • 161kcals
  • 9g total fat
  • 4g protein
  • 16g total carbohydrates
  • 4g fiber
  • 12g net carbs

According to Campbell’s, one serving of Classic Green Bean Casserole has the following nutrition information:

  • 227kcals
  • 15.4g total fat
  • 2.3g protein
  • 19.5g total carbohydrates
  • 2.6g fiber
  • 16.9g net carbs

How to Make Fresh Green Bean Casserole

The classic recipes for Green Bean Casserole first combines milk, condensed mushroom soup, and black pepper as a base sauce. After that, canned or pre-cooked green beans are mixed into the sauce and the mixture is baked until hot. Lastly, crispy fried onions are sprinkled on top and the casserole is baked a few minutes until golden.

The Secret to Making the Best Green Bean Casserole

I’ve had a lot of Green Bean Casserole recipes in my day, and I’ve found that there are two big factors that take this casserole from ok to great. The first is the green beans! I will never use canned (ugh, mush) and I don’t even like using frozen green beans.

My preference is to use fresh green beans, cooked until just fork-tender. It’s important not to overcook the green beans before you assemble the casserole, because the beans will cook more as the casserole cooks. And no one likes mushy, overcooked vegetables!

The second aspect that takes a green bean casserole to the next level is the creamy mushroom sauce. The classic recipe calls for condensed mushroom soup, but I much prefer sauteeing mushrooms with onion and garlic and making my own quick and easy version of mushroom soup instead. You won’t believe how much more flavorful it is!

How to Make Cheesy Green Bean Casserole

To turn any green bean casserole into a cheesy green bean casserole recipe, just stir in one to two cups of shredded cheddar cheese before baking. Add more or less depending on how cheesy you want it. (Note that this will change the nutrition information for the recipe.)

How to Make Instant Pot Green Bean Casserole

I love using my Instant Pot to make a really quick version of this recipe as easily as possible! First, use the Instant Pot’s sauté function to sauté onion, mushrooms, and garlic, and then add cream cheese, chicken stock, heavy cream, and a few seasonings to make the creamy sauce.

Then, add the green beans and set the pot to cook for 1 minute on Manual, High Pressure. After that, pour the mixture into a casserole dish, top it with a low carb keto breadcrumb substitute, and then bake it until it’s hot throughout and browned on top.

How to Make Green Bean Casserole in the Oven

If you don’t have an Instant Pot, this recipe is also easy to make on the stovetop and in the oven. First, sauté the vegetables (onion, mushroom, and garlic) on the stovetop, and then mix in the other sauce ingredients.

Then, cook the green beans until fork-tender (I like to steam them, or boil them for about 5 minutes). Next, mix the cooked green beans into the creamy sauce and pour it into a casserole dish. (See the Notes below the recipe for full instructions on how to make green bean casserole in the oven.)

Low Carb Instant Pot Green Bean Casserole Recipe Before Baking

Ingredients in this Low Carb Instant Pot Green Bean Casserole Recipe

  • Butter
  • Yellow onion
  • Button mushrooms
  • Garlic
  • Cream cheese
  • Chicken stock or bone broth
  • Heavy cream
  • Worcestershire sauce
  • Tamari sauce or coconut aminos
  • Fresh lemon juice
  • Black pepper
  • Green beans
  • Almond flour
  • Freshly-grated Parmesan cheese
  • Dried Italian herb seasoning
  • Garlic powder
  • Onion powder
  • Extra-virgin olive oil

Yes, this does seem like a lot more ingredients than a typical green bean casserole that normally just has 5, BUT it’s totally worth it! Not only is our green bean casserole low carb, but it tastes amazing too!

Is Green Bean Casserole Keto?

Our Low Carb Instant Pot Green Bean Casserole Recipe is easy to fit into a keto-friendly lifestyle! One serving of our recipe has the following nutrition information:

  • 246kcals
  • 21g total fat
  • 7g protein
  • 9g total carbohydrates
  • 2g fiber
  • 7g net carbs

A typical green bean casserole isn’t the best for a keto diet because it has condensed cream of mushroom soup, fried onions, and milk.

  • Caramelized Brussels Sprouts with Dark Cherry Sauce and Hazelnut from An Edible Mosaic
  • One-Skillet Balsamic Glazed Sauteed Asparagus with Bacon from The Keto Queens
