ULTIMATE Green Bean Casserole

Prep Time:

15 Minutes

Cook Time:

45 Minutes




  • 3 slices thick-cut bacon , diced

  • 1/2 cup finely chopped yellow onion

  • 2 cloves garlic , minced

  • 12 ounces fresh button or cremini mushrooms , chopped

  • 3 tablespoons butter

  • 3 tablespoons all-purpose flour

  • 1 cup half-and-half

  • 1 cup chicken broth

  • 1/2 cup shredded white cheddar cheese

  • 3/4 teaspoon salt

  • 1/4 teaspoon freshly ground black pepper

  • 1 pound fresh green beans , trimmed, halved, and blanched (boil 5 minutes, place beans in ice water for a couple of minutes, drain)

  • 1 can quality French fried onions


  • Preheat the oven to 350 degrees F.

  • Fry the bacon in a large skillet over medium-high heat until crispy. Add the onions and cook until soft and translucent, about 4-5 minutes. Add the mushrooms and garlic and cook for another 4-5 minutes until the mushrooms are soft. Transfer the mixture to a bowl.

  • Melt the butter in the same skillet and whisk in the flour. Once combined, continue whisking for another 2 minutes until the mixture has slightly deepened in color. Add the half-and-half and chicken broth while constantly whisking to prevent lumps. Once slightly thickened, add the cheese and whisk until melted and combined.

  • Next add the mushroom/bacon mixture along with the salt and pepper. Let the sauce simmer for a couple of minutes, then add the green beans. Stir to combine.

  • Pour the bean mixture into a 9x13 casserole dish and sprinkle the French fried onions all over the top. Bake uncovered for 30 minutes until bubbling and the onions are golden and crispy. Let sit for 5 minutes before serving.
