Classic Green Bean Casserole From Scratch

Classic Green Bean Casserole From Scratch


  • Total Time: 50 minutes
  • Diet: Vegetarian

Ingredients

Scale
  • 1.5 pounds fresh green beans, trimmed and halved
  • 3 tablespoons unsalted butter
  • 8 ounces fresh cremini or button mushrooms, sliced
  • 2 cloves garlic, minced
  • 3 tablespoons all-purpose flour
  • 1 1/2 cups whole milk
  • 1/2 cup heavy cream
  • 1/2 teaspoon salt, or to taste
  • 1/4 teaspoon ground black pepper
  • 1/4 teaspoon onion powder
  • 1 1/2 cups crispy fried onions (halal-certified)

Instructions

  1. Preheat your oven to 375°F (190°C). Grease a 9×13 inch baking dish or a large casserole dish with a little butter.
  2. Bring a large pot of salted water to a boil. Add the fresh green beans and cook for about 5 minutes until they are bright green and slightly tender. Immediately drain them and plunge them into a bowl of ice water to stop the cooking. Drain again and set aside.
  3. In a large skillet or saucepan, melt the 3 tablespoons of butter over medium heat. Add the sliced mushrooms and cook for 5 to 7 minutes until they are browned and their liquid has evaporated. Add the minced garlic and cook for another minute until fragrant.
  4. Sprinkle the flour over the mushrooms and stir constantly for 1 to 2 minutes to cook out the raw flour taste.
  5. Slowly whisk in the milk and heavy cream. Continue to whisk over medium heat until the sauce thickens and begins to bubble. This should take about 5 minutes.
  6. Season the sauce with salt, black pepper, and onion powder. Taste and adjust seasoning if needed.
  7. Add the blanched green beans to the skillet and toss them gently to coat them thoroughly in the creamy mushroom sauce.
  8. Pour the mixture into your prepared baking dish. Spread it out evenly with a spatula.
  9. Place the dish in the oven and bake for 20 minutes until the sauce is bubbling around the edges.
  10. Remove from the oven and sprinkle the crispy fried onions evenly over the top. Return the dish to the oven for another 5 to 10 minutes until the onions are golden brown and extra crunchy. Serve hot.
