Description

A classic Green Bean Casserole made with fresh green beans, a creamy mushroom sauce, and crispy fried onions, baked to golden perfection. This comforting side dish is perfect for holiday meals or any family dinner.


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 & Broth

  • 2 tablespoons unsalted butter
  • 2 cups half & half
  • 1 cup chicken or vegetable broth

Seasonings & Others

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


Instructions

  1. Preheat Oven: Preheat your oven to 375°F (190°C) to prepare for baking the casserole.
  2. Blanch Green Beans: Bring a large pot of salted water to a boil. Add the green beans and cook for 2-3 minutes until bright green and slightly tender. Immediately transfer them to a bowl of ice water to stop the cooking, then drain and set aside.
  3. Sauté Vegetables: 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 begin to brown.
  4. Add Flour: Sprinkle the flour over the mushroom mixture and stir to coat evenly. Cook for 1-2 minutes to eliminate the raw flour taste.
  5. Make Sauce: Gradually whisk in the chicken or vegetable broth and half & half, stirring constantly to avoid lumps. Add soy sauce, salt, black pepper, and ground nutmeg. Simmer for about 5 minutes, stirring often, until the sauce thickens.
  6. Combine Ingredients: In a 9×13-inch casserole dish, combine the blanched green beans, mushroom sauce, and ½ cup of crispy fried onions. Mix thoroughly to evenly coat the green beans.
  7. Top with Onions: Spread the green bean mixture into an even layer in the dish. Sprinkle the remaining crispy fried onions evenly over the top.
  8. Bake: Bake in the preheated oven for 20-25 minutes, or until the sauce is bubbling and the onions on top are golden brown. Let cool for a few minutes before serving.

Notes

  • For a vegetarian version, use vegetable broth instead of chicken broth.
  • Fresh green beans provide the best texture and flavor, but frozen green beans can be used in a pinch.
  • Make sure to blanch and shock the green beans in ice water to maintain their bright color and crisp-tender texture.
  • You can prepare the mushroom sauce ahead of time and assemble everything before baking.
  • If you prefer a richer sauce, substitute some of the half & half with heavy cream.
