Martha Stewart Green Bean Casserole Recipe Ingredients
- 3 cups vegetable oil
- 6 large shallots, cut into very thin rounds, rings separated
- 1 1/2 cups all-purpose flour
- Coarse salt and ground pepper
- 2 pounds green beans, trimmed and halved
- 1/4 cup (1/2 stick) unsalted butter
- 1 pound button mushrooms, trimmed and coarsely chopped
- 14 1/2 ounces low-sodium chicken broth
- 1 cup whole milk

How To Make Martha Stewart Green Bean Casserole Recipe
- Preheat oven and heat oil: Preheat oven to 425°F. In a large skillet, heat vegetable oil over medium heat. Line a baking sheet with paper towels.
- Coat and fry shallots: In a large bowl, toss shallots with 1 1/4 cups flour. Shake off excess flour and fry in batches until golden and crisp, about 5 minutes. Transfer to the lined sheet and season with salt. Set aside.
- Cook and cool green beans: In a large pot of salted boiling water, cook green beans until crisp-tender, about 6 minutes. Drain, rinse with cold water to stop cooking, and pat dry.
- Cook mushrooms and add flour: Melt butter in a large saucepan over medium-high heat. Add mushrooms and cook until liquid evaporates, about 7 minutes. Season with salt and pepper. Stir in 1/4 cup flour and cook for 1 minute.
- Make sauce: Gradually whisk in chicken broth, then milk. Bring to a simmer and cook until thickened, about 5 minutes. Season with salt and pepper. Reheat if needed before using.
- Assemble and bake: Toss green beans in the mushroom sauce until well coated. Transfer to a 9×13-inch baking dish and bake for about 15 minutes until bubbling at the edges.
- Top and serve: Sprinkle the fried shallots over the casserole just before serving.
