I have grown up always having the classic green bean casserole with the canned cream of mushroom soup and canned green beans for Thanksgiving. I made this homemade version and my family was blown away. Never again will we be going back to the canned kind. It has an extra crunchy topping and is bursting with mushroom flavor. It is absolutely amazing!
Ingredients:
TOPPING:
- 1/2 cup panko bread crumbs
- 1 tablespoon butter, melted
- 2 1/2 cups canned fried onions
CASSEROLE:
- 2 pounds fresh green beans, trimmed and cut into 1-inch pieces
- 3 tablespoons butter
- 1 pound cremini or baby bella mushrooms, chopped
- 1/4 teaspoon dried thyme
- 2 garlic cloves, finely minced
- 1 teaspoon salt
- 1/4 teaspoon black pepper
- 1/4 cup all-purpose flour
- 1 1/2 cups chicken broth (I use low-sodium)
- 3/4 cup heavy cream
- 3/4 cup milk (1%, 2% or whole)
Directions:
Preheat the oven to 400 degrees. Lightly grease a 9X13-inch baking dish and set aside.
FOR THE TOPPING, in a medium bowl stir together the panko bread crumbs and the melted butter. Add the fried onions and toss.
For the casserole, in a microwave-safe bowl, combine the green beans and 1/2 cup water. Cover and microwave for 6-8 minutes, stirring once, until the green beans are slightly tender (they’ll cook longer in a later step).
Drain the green beans and transfer them to the prepared baking dish.
In a 12-inch nonstick skillet set over medium heat, melt the butter. Add the mushrooms, thyme, garlic, salt and pepper, and cook, stirring often, until the liquid is mostly evaporated and the mushrooms are tender, 5-7 minutes.
Stir in the flour and cook for another minute or two, stirring constantly. Slowly whisk in the chicken broth until it is all incorporated and the mixture is smooth. Add the heavy cream and milk, and whisk until well-combined. Bring the mixture to a simmer, and cook, stirring occasionally, until the sauce has thickened, about 5 minutes. Add additional salt and pepper to taste, if needed.
Pour the sauce over the green beans and toss to combine.
Bake the casserole for 20 minutes, until the green beans are mostly tender. Remove from the oven and sprinkle the topping mixture evenly over the top. Bake for another 5-10 minutes (watch carefully so the topping doesn’t burn).
Let the casserole cool for 5-10 minutes before serving.
