Ingredients
 
 

  • 1 lb green beans
  • 6 tablespoon butter divided
  • 3 cloves garlic minced
  • 2 large shallots thinly sliced
  • 2-3 C mixed mushrooms sliced
  • ¼ C flour
  • 2 C whole milk
  • 1 C chicken stock I like unsalted
  • 1 C parmesan cheese
  • ½ teaspoon salt
  • ¼ teaspoon pepper
  • 1 C French's Crispy Fried Onions

Instructions
 

  • Preheat your oven to 350°F.
  • Prep your green beans and add them to a microwave safe dish. Add 1 cup of water, cover, and microwave on high for 3 minutes. While the beans are in the microwave, prepare a large bowl of ice water. Immediately transfer the beans to the ice water to stop the cooking process.
    Drain, and then set aside in a large bowl.
  • In a large saucepan over medium high heat, melt 2 tablespoon of butter. Add the garlic and shallot. Cook until fragrant, about 1 minute. Add the mushrooms. Sauté until soft, about 6-8 minutes.
    Add the mushroom mixture to the same bowl the green beans are in.
  • In the same saucepan (no need to clean it), add the remaining 4 tablespoon of butter. Let it melt, then whisk in the flour. Cook the roux, whisking the entire time. Add the milk slowly, continuously whisking. Repeat with the chicken stock. Allow the sauce to cook for about 5 minutes. It should thicken up enough to coat the back of a spoon.
  • Add the parmesan cheese, salt, and pepper. Stir until the cheese is melted. Add the sauce to the bowl with the beans and mushrooms. Mix well.
  • Pour the casserole mixture into an 8x8" casserole dish. Bake for 30 minutes, until bubbly and hot.
  • Add the French's Crispy Fried Onions evenly over the top. Return to the oven and bake for another 5 minutes, until golden and crispy.
  • Serve.

Do NOT add the fried onions right at the beginning of the baking process. They will burn.
