Green bean casserole from scratch Recipe
Ingredients
- 2 pounds fresh green beans, ends trimmed, cut into 2-inch lengths
- 2 teaspoons olive oil
- 2 medium yellow onions, thinly sliced
- 1 pound crimini or white mushrooms, cleaned and sliced
- 3 Tablespoons butter
- 3 Tablespoons all-purpose flour
- 2 cups milk
- 2 Italian porcini bouillon cubes
- 2 cups canned french fried onions, divided
- 1/2 teaspoon sea salt
- 1/4 teaspoon freshly ground black pepper
Instructions
Bring a large pot of water to a boil. Drop in the green beans and boil rapidly until softened but still bright green, about 5 minutes. Drain and let cool 20 minutes. When the beans are cool enough to handle, pull them apart lengthwise with your fingers (this is called frenching the beans). This step is optional but it helps the green beans meld with the cream sauce, so I recommend taking the time to do it.While the water is coming to a boil and the green beans are cooking, heat the olive oil in a large skillet. Add the onions and mushrooms and cook over medium-high heat until the onions are golden brown and the water from the mushrooms has evaporated completely. Put the green beans, mushrooms and onions into a large mixing bowl.In the same skillet used to cook the onions and mushrooms, melt the butter over medium-low heat and add the flour, stirring to make a paste. Cook the paste about 2 minutes to get rid of the raw flour taste. Add the milk and whisk quickly to dissolve the butter-flour paste - it's important to do this thoroughly or there will be lumps. Crumble the porcini bouillon cubes into the cream sauce and continue to whisk until the sauce is smooth and thickened. Pour the cream sauce over the vegetables in the mixing bowl.Preheat the oven to 350 degrees. Spray a large casserole dish with nonstick cooking spray.Add 1 cup of the canned french fried onions to the mixing bowl along with the salt and pepper. Mix thoroughly. Pour the green bean mixture into the prepared casserole dish. Bake the green bean casserole about 30 minutes, until the sauce bubbles up around the edges. Spread the remaining 1 cup of french fried onions on top of the casserole and bake another 10 minutes. Serve immediately.
