Ingredients You Need

ingredients for green bean casserole
  • Green Beans – It’s best to use fresh green beans (aka string beans or snap beans). You can also use wax beans or purple beans. I’ve also used broad bean pods successfully in this recipe.
  • Bacon – I’m a big believer that bacon makes everything better!
  • Shallot – I tend to go light on the onions because they have a higher carb count, so a shallot is the perfect substitute. You can use as much as you like, or add some green onions instead that have less carbs.
  • Garlic – Always use fresh garlic that hasn’t been kept in the refrigerator for too long. This has the best flavor and no bitterness that comes from older garlic.
  • Cream Cheese– For a keto diet, I always recommend buying full fat diary products, especially cream cheese. The low fat version is not very good. This needs to be softened ahead of time, so be sure to remove it from the refrigerator beforehand.
  • Worcestershire sauce – This add such a punch of umami flavor.
  • Dijon mustard – Give the dish a bit of an acidic kick with a creamy Dijon mustard
  • Chicken broth – Use a low-sodium broth to not add extra salt to the dish. You can also use water mixed with bouillon cubes.
  • Salt & pepper – This is what really brings the flavor out in this dish, so be sure to add the salt and pepper. You might also taste the dish once it’s done cooking and add more to suit your taste.
  • Cheddar cheese – I always shred my own cheese for recipe because pre-shredded often comes coated with flour or another anti-stick agent that I don’t want to add to my food.
  • Crispy Onions – I like to add crispy onions on top of the casserole, which you can do by making them yourself or buying them. Check the package for carb details to avoid buying one that is loaded with carbs. To make them, cut the onions into slices and then into about 1″ pieces. Toss them with coconut flour and fry in a pan with oil until crispy.

Equipment Needed

This dish requires a few different dishes to get the job done. You’re going to need:

  • An oven-safe 8×8″ square or round dish
  • Medium pot
  • Colander
  • Frying pan
  • Whisk

How to Make Keto Green Bean Casserole

Preheat the oven to 350°F.

Bring a pot of water to a boil over high heat. Add the green beans and blanch them for 3 minutes. Blanching is just rapidly cooking them for a quick period of time. I prefer my beans to have a little crunch in them, so I blanch them for 4 minutes. If you want them to be crispier, cook for 3 minutes. And softer cook for 5 minutes.

blanching the green beans

Drain the beans and set them aside.

In a pan over medium heat, add the olive oil. When hot, add the shallots and sauté for 5 minutes. Add the garlic and cook for 30 seconds.

Additional Tips & Substitutions

  • Avoid overcooking the green beans, as they will become brown and soggy. It’s best not to blanch them longer than 4 minutes.
  • You can use canned green beans if it’s the only thing you can get, but they won’t have the same nice crunch to them. If you use canned beans, there’s no need to blanch them prior to adding them to the sauce.
  • It’s always best to shred the cheese yourself from a blog so it doesn’t have the anti-caking agent on it that can keep it from melting well.
  • If you don’t like cheddar or don’t have it on hand, you can substitute it with Monterey Jack or even Mozzarella.
