Ingredients

• 900 grams fresh green beans, trimmed and cut into 2-inch pieces
• 4 tablespoons unsalted butter
• 1 medium yellow onion, finely chopped
• 3 cloves garlic, minced
• 250 grams mushrooms, finely chopped
• 3 tablespoons all-purpose flour
• 480 milliliters chicken or vegetable broth
• 240 milliliters heavy cream
• 1 teaspoon soy sauce
• 0.5 teaspoons salt
• 0.5 teaspoons black pepper
• 150 grams crispy fried onions

Directions

Step 1

Preheat your oven to 375°F (190°C).

Step 2

Bring a large pot of salted water to a boil. Add the green beans and blanch for 5 minutes. Drain and transfer the beans to an ice water bath to stop the cooking process. Drain again and set aside.

Step 3

In a large skillet, melt the butter over medium heat. Add the chopped onion and sauté until translucent, about 3-4 minutes. Add the minced garlic and sauté for an additional minute.

Step 4

Add the mushrooms to the skillet and cook until softened and any liquid released by the mushrooms has evaporated, about 5-7 minutes.

Step 5

Sprinkle the flour over the mushroom mixture and stir well to coat. Cook for 1-2 minutes to eliminate the raw flour taste.

Step 6

Gradually pour in the chicken or vegetable broth while whisking constantly to avoid lumps. Add the heavy cream and soy sauce, then stir until the mixture is smooth and thickened, about 3-4 minutes.

Step 7

Season the sauce with salt and black pepper to taste. Remove the skillet from the heat.

Step 8

In a large mixing bowl, combine the blanched green beans with the mushroom sauce and stir until the beans are evenly coated.

Step 9

Transfer the mixture to a 9x13-inch (23x33 cm) baking dish. Spread it into an even layer and sprinkle the crispy fried onions evenly over the top.

Step 10

Bake the casserole in the preheated oven for 20-25 minutes, or until the top is golden brown and the sauce is bubbling.

Step 11

Remove from the oven and let it rest for 5 minutes before serving. Enjoy your Thanksgiving Green Bean Casserole!
