Scale

Ingredients

  • 4 tablespoons butter
  • 1 cup diced onion
  • 1 tablespoon chopped garlic
  • 4 tablespoons flour
  • 1 1/2 cups chicken broth
  • 3/4 cup heavy cream
  • 1 cup gruyere or white cheddar cheese or a combination of both)
  • 3 cans (14.5 oz.) french green beans {*can substitute fresh, see note} rinsed and drained
  • 2 cans (8 oz.) sliced mushrooms {*can substitute fresh, see note} rinsed and drained
  • 1 1/2 teaspoons kosher salt
  • 1/23/4 teaspoons ground black pepper (to taste)
  • 1/4 teaspoon fresh grated nutmeg
  • 1 1/2 cups fried onions (I used French’s)

Instructions

  1. Preheat the oven to 400 degrees.
  2. Add the butter to a large skillet over medium heat. Once the butter is melted, add the onion and cook for 3-4 minutes to soften.
  3. Add the garlic to the pan and then cook a minute longer. Whisk in the flour, stir the flour into the onions and cook for 1 minute.
  4. Pour in the chicken broth and whisk until the flour is incorporated into the broth. Stir in the cream and bring to a simmer to thicken for 2-3 minutes.
  5. Whisk the cheese into the sauce then season with salt, pepper and nutmeg.
  6. Add the green beans and mushrooms and stir to combine with the sauce. Remove the skillet from the heat.
  7. Pour the mixture into an 9″ x 13″ baking dish (2 quarts) and top with the fried onions.
  8. Bake for 25 minutes until the filling is bubbling. Let the casserole rest for 5 minutes before serving.

Recipe Notes

* If substituting fresh green beans you’ll need about 2 pounds of beans, trimmed and steamed or blanched. To steam the beans add them to a glass bowl with 2 tablespoons of water, cover with plastic wrap and cook in the microwave for 5 minutes.

To blanche the beans, add them to salted boiling water for 5 minutes and drain.

* To substitute fresh mushrooms, you’ll need an 8 ounce package of mushrooms, cleaned and sliced. Add the mushrooms to the skillet after the onions have cooked and before the garlic goes in. Cook the mushrooms for 5 minutes until browned, then continue with the instructions.
