Updated Green Bean Casserole
  • 2 pounds whole green beans, ends trimmed if using fresh
  • 6 tablespoons butter, divided
  • 1 onion, diced
  • 1 pound mushrooms, sliced
  • 1 teaspoon kosher salt
  • ½ teaspoon pepper
  • 2 teaspoons dried thyme
  • 1 teaspoon minced garlic
  • ¼ cup flour
  • 3 cups whole milk
  • ¼ teaspoon Nutmeg
  • 1 teaspoon soy sauce
  • 2 cups Swiss cheese, shredded (8 ounces)
  • Large can French’s fried onions
  1. Cook beans in large pot of salted boiling water. Cook 4 to 5 minutes until fork tender. Drain and rinse with cold water. Drain well and transfer to a large mixing bowl.
  2. Melt 3 tablespoons butter in large skillet over medium heat, add chopped onion and mushrooms. Season mushrooms and onion with 1 teaspoon salt, ½ teaspoon pepper, and 2 teaspoons dried thyme. Cook over medium heat until mushrooms release their liquid and there is only about 2 tablespoons liquid left in the skillet. Add the teaspoon of minced garlic and cook about 1 minute until fragrant. Transfer to the large mixing bowl and mix with the cooked beans.
  3. In the same skillet melt the remaining 3 tablespoons of butter over medium heat, add flour. Stir constantly and cook for about 1 minute. Slowly pour in milk and bring to a simmer over medium heat. Let simmer about 5 minutes until thickened, whisk frequently to keep from scorching. Add ¼ teaspoon of nutmeg and season to taste with salt & pepper. I used ¾ teaspoon kosher salt and ½ teaspoon pepper. Remove from heat and let cool.
  4. Pour cooled sauce over bean mixture and stir to coat. Add 2 cups Swiss cheese and stir to blend. Spoon into a greased 3 quart baking dish.
  5. Bake at 350 degrees for 40 minutes until sauce is bubbly. Top with French’s Onions and cook about 5-10 more minutes.
  6. Cook's Note: If the fresh green beans don't look that fresh I have had great results with frozen. Dillon's Private Selection has a petite frozen whole green bean. Sam's Club also had a really nice frozen bean. The Private Selection beans you can steam in the bag. I just put them in for a little less time than the package direction because they will continue cooking in the oven and you don't want mushy beans. I wouldn't recommend getting the thick cut green beans.
