If you are looking for a low-carb recipe to bring along to ensure you have something you can enjoy, try our recipe for low-carb green bean casserole!

Your family is sure not to miss the calorie-heavy version they are used to.

Why Isn’t Traditional Green Bean Casserole Low Carb?

The traditional version of green bean casserole is made with canned green beans, canned cream of mushroom soup, milk, seasonings and French fried onions. Although delicious, it is not a low-carb dish.

French fried onions, mushroom soup and milk contribute to the overall carb count.

Are Canned or Fresh Green Beans Better for Casserole?

Fresh green bans are the healthiest version of the veggies. You can use frozen green beans if you wish to and the result will be delicious.

Many people use canned green beans but they will not be as crisp and fresh tasting. We suggest fresh or frozen for optimal results.

Can You Overcook Green Bean Casserole?

if you overcook the casserole, the green beans may get mushy. Take care not to overcook them.

  • Olive oil for frying


  • Peel and slice the onion very thinly.

  • Cook coated onions in batches (2-4 minutes) until golden brown.

  • Remove with a slotted spoon and set them on a plate covered with a paper towel to blot off some of the oil.
