Ingredients

  • 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

Instructions

  • 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.

Notes

Preparing in Advance: Everything can be done in advance except for adding the crispy onions, otherwise they'll get soggy. Add those just before baking. Also, let the casserole sit for at least 30 minutes after removing it from the fridge before baking.
