Ingredients

Scale

Vegetables

  • 2 pounds fresh green beans, trimmed and cut into 2-inch pieces
  • 1 medium yellow onion, finely chopped
  • 3 cloves garlic, minced
  • 8 ounces button or cremini mushrooms, sliced

Dairy and Fats

  • 2 tablespoons unsalted butter
  • 2 cups half & half

Pantry Items

  • ¼ cup all-purpose flour
  • 1 cup chicken or vegetable broth
  • 1 teaspoon soy sauce
  • ½ teaspoon salt
  • ½ teaspoon black pepper
  • ¼ teaspoon ground nutmeg
  • 1½ cups crispy fried onions


Instructions

  1. Preheat the oven: Preheat your oven to 375°F (190°C) to prepare for baking the casserole later.
  2. Blanch the green beans: Bring a large pot of salted water to a boil. Add the green beans and cook for 2-3 minutes until they turn bright green and are slightly tender. Immediately transfer them to a bowl of ice water to stop the cooking process. Drain and set aside.
  3. Sauté onions and mushrooms: In a large skillet, melt the butter over medium heat. Add the chopped onion and cook for 3-4 minutes until softened. Stir in the minced garlic and sliced mushrooms, cooking for 5-7 minutes until the mushrooms release their moisture and start to brown.
  4. Add flour: Sprinkle the flour over the mushroom mixture and stir to coat evenly. Cook for 1-2 minutes to remove the raw flour taste, ensuring a smooth sauce later.
  5. Make the sauce: Gradually whisk in the chicken or vegetable broth and half & half, stirring constantly to prevent lumps. Add soy sauce, salt, black pepper, and ground nutmeg. Simmer for about 5 minutes, stirring often, until the sauce thickens to a creamy consistency.
  6. Combine green beans and sauce: In a 9×13-inch casserole dish, add the blanched green beans, mushroom sauce, and half a cup of the crispy fried onions. Mix everything together directly in the dish until the green beans are evenly coated. Spread the mixture into an even layer.
  7. Add topping: Sprinkle the remaining crispy fried onions evenly over the top of the casserole for a crunchy finish.
  8. Bake the casserole: Bake in the preheated oven for 20-25 minutes, or until the sauce is bubbling and the onions on top are golden brown. Remove from oven and let it cool for a few minutes before serving. Enjoy!

Notes

  • For extra flavor, try adding a teaspoon of Worcestershire sauce with the soy sauce in the sauce step.
  • Fresh green beans are preferred, but frozen can be used if blanched properly.
  • Make sure to cool the beans quickly in ice water to retain their bright color and crisp texture.
  • Use vegetable broth to keep the dish vegetarian-friendly.
  • Crispy fried onions can be store-bought or homemade for best crunch.
