Ingredients

• 1 pound fresh green beans
• 8 ounces button mushrooms
• 3 tablespoons butter
• 3 cloves garlic
• 3 tablespoons all-purpose flour
• 1 cup chicken or vegetable broth
• 1 cup heavy cream
• 1 teaspoon soy sauce
• 0.5 teaspoon salt
• 0.5 teaspoon black pepper
• 0.5 cup parmesan cheese, grated
• 1.5 cups crispy fried onions
• 0 water

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 them for 5 minutes, then transfer to a bowl of ice water to stop cooking. Drain and set aside.

Step 3

In a large skillet over medium heat, melt the butter. Add the sliced mushrooms and cook for 6-8 minutes until they release their moisture and turn golden brown.

Step 4

Add minced garlic to the mushrooms and sauté for another 1 minute until fragrant.

Step 5

Sprinkle the flour over the mushrooms, stirring constantly for 1-2 minutes to cook the raw taste out of the flour.

Step 6

Slowly pour in the chicken or vegetable broth while whisking to create a smooth sauce. Add the heavy cream, soy sauce, salt, and black pepper. Let the mixture simmer for 3-4 minutes until thickened.

Step 7

Stir in the blanched green beans and grated Parmesan cheese, ensuring everything is well coated in the creamy mushroom sauce.

Step 8

Transfer the mixture to a 9x13-inch baking dish. Spread it out evenly.

Step 9

Top the casserole with a layer of crispy fried onions.

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 cool for 5 minutes before serving. Enjoy your Mushroom Green Bean Casserole!
