Adapted from Martha Stewart
6 tablespoons butter
1 medium onion, diced small
1 pound white mushrooms, sliced
2 teaspoons sea salt
black pepper to taste
1 1/2 pounds green beans, trimmed and cut into bite-size pieces
¼ cup all-purpose flour
2 cups milk
1 pinch grated nutmeg
1/2 cup grated Parmesan cheese
1/4 cup breadcrumbs
1 can Lars’ Own Crispy Onions*
- In a large skillet over medium heat, melt 2 tablespoons butter. Add onion, and saute about 5 minutes. Add mushrooms, and cook until most of the liquid has evaporated, about 8 minutes. Season with 1 teaspoon salt and black pepper. Set aside to cool.
- Cook beans in boiling water until tender about 5 minutes. Pour into a colander and rinse with cold water. Set aside.
- Melt the remaining 4 tablespoons butter in a medium saucepan over medium-low heat. Add 1/4 cup flour, and whisk constantly until mixture begins to turn golden, about 2 minutes. Pour in milk, and continue whisking until mixture has thickened, about 3 minutes. Stir in nutmeg, and the remaining teaspoon salt and additional pepper. Remove from heat, and let cool to room temperature, stirring occasionally. Mix sauce with beans in a bowl.
- Pour beans into a greased 9 x 13 inch baking pan. Combine Parmesan and breadcrumbs and sprinkle over casserole.
- Cover beans with foil and bake at 425 until heated through, about 30 minutes. Uncover, set oven to broil, and cook until top is golden brown, about 1 minute. Sprinkle fried onions over top and serve immediately.
