12 servings

  • 2 lb green beans, trimmed
  • 8 tablespoons unsalted butter, 1 stick, divided
  • 2 medium white onions, thinly sliced
  • 1 ½ lb cremini mushroom, sliced and stemmed
  • 5 cloves garlic, sliced
  • 3 tablespoons all-purpose flour
  • 1 cup milk
  • ½ cup heavy cream
  • 2 teaspoons kosher salt
  • 1 teaspoon freshly ground black pepper
  • 1 cup chicken broth, or vegetable broth
  • ½ cup grated parmesan cheese
  • 1 cup store-bought fried onions

Instructions

  • Preheat the oven to 400˚F (200˚C).
  • In a large pot of salted boiling water, blanch the green beans for 3 minutes, until tender and bright green. Drain and transfer to a 9x13-inch (23x33 cm) baking dish.
  • Melt 4 tablespoons of butter in a large pan over high heat. Add the onions and cook for 8 minutes, until softened and translucent.
  • Add the mushrooms and cook for 5 minutes, until browned. Add the garlic and cook just until fragrant, about 1 minute.
  • Transfer the vegetable mixture to the casserole dish with the green beans. Wipe out the pan.
  • Melt the remaining 4 tablespoons of butter in the same pan. Add the flour and stir to combine. Cook until a golden brown roux forms, for 5 minutes.
  • Add the milk, heavy cream, salt, pepper, chicken broth, and Parmesan cheese, and stir to combine. Reduce the heat to medium-low and cook until the sauce is thickened, about 10 minutes.
  • Pour the sauce evenly over the vegetables in the casserole dish and toss until everything is well coated. Cover with foil.
  • Bake for 20 minutes, then remove the foil and bake for another 10 minutes.
  • Top the casserole with the fried onions, then serve.
  • Enjoy!
