Green Bean Casserole

Preheat the oven to 350°F (175°C).

Bring a large pot of water to a boil and blanch the green beans for 5 minutes. Drain and rinse with cold water to stop the cooking process.

In a skillet, melt the butter over medium heat. Add the mushrooms and cook until they release their moisture and become golden brown.

Stir in the flour and cook for an additional 2 minutes, until it is well incorporated.

Gradually pour in the chicken broth and milk, stirring continuously until the sauce thickens. Season with salt, black pepper, and garlic powder.

Add the blanched green beans to the sauce and mix well to coat them evenly.

Transfer the mixture to a casserole dish and spread it out evenly.

Bake in the preheated oven for 20 minutes.

Remove the casserole from the oven and sprinkle the fried onions on top.

Return to the oven and bake for an additional 10 minutes, until the onions are golden and crispy.

Let it cool for a few minutes before serving.
