Every family holiday gathering needs a classic green bean casserole. For this Classic Green Bean Casserole recipe, we took an oldie but a goodie and skinnied it up. To do it, we used Greek yogurt instead of the usual canned cream soup to achieve that creamy texture, and opted for baked red onions in place of fried onion strings.

This casserole recipe has all the flavors you love in the classic version, but with only half the fat and calories, and none of the artificial ingredients. Give it a try for your next holiday gathering and let us know what you think!

  • 1 pound green beans, ends trimmed
  • 1 large red onion, sliced thin
  • 2 tablespoon olive oil
  • 1/2 cup yellow onion, diced
  • 1 1/2 cups mushrooms, sliced
  • 1/2 teaspoon Kosher salt
  • 1/4 teaspoon ground pepper
  • 1 teaspoon dried thyme
  • 1 clove garlic, minced
  • 1/2 cup skim milk
  • 1/2 cup plain Greek yogurt


Preheat oven to 350. Spray a 9X13 inch casserole pan with nonstick spray.

Bring a large pot of water to a boil. Add green beans and quickly cook for 2 to 3 minutes. Quickly drain beans and submerge in cold water to stop the cooking process.

Toss the sliced red onion in 1 tablespoon of olive oil. Place on baking sheet and bake until crisp, about 45 minutes. Remove from oven and cool uncovered.

Meanwhile, heat olive oil in skillet on medium heat. Add onion, mushrooms, salt, and pepper. Cook until mushrooms have released their liquid and onions are translucent. Stir in thyme and garlic and cook until fragrant.

Add milk to the mushroom mix. Bring to a boil and quickly whisk in yogurt until smooth and creamy. Remove from heat and add green beans. Toss to coat in mushroom mix, if the mix is too thick add skim milk one tablespoon at a time to thin. Pour into prepared casserole dish and bake for 15 minutes or until bubbly. Top with crispy red onions, and serve!
