We made a cheesy, creamy sauce from scratch for our version of this green bean casserole and we just know you’re going to LOVE it!
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
- 1/2 – 3/4 teaspoons ground black pepper (to taste)
- 1/4 teaspoon fresh grated nutmeg
- 1 1/2 cups fried onions (I used French’s)
Instructions
- Preheat the oven to 400 degrees.
- 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.
- 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.
- 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.
- Whisk the cheese into the sauce then season with salt, pepper and nutmeg.
- Add the green beans and mushrooms and stir to combine with the sauce. Remove the skillet from the heat.
- Pour the mixture into an 9″ x 13″ baking dish (2 quarts) and top with the fried onions.
- 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.
