The Ultimate Green Bean Casserole with Crispy Fried Shallots
We gave the classic green bean casserole a delicious makeover. Sautéed cremini mushrooms and blanched green beans are combined with a luscious sauce of chicken stock and cream. Then the dish is topped with homemade fried shallot rings and baked until bubbling. For a vegetarian version, substitute vegetable or mushroom stock for the chicken stock.
- Unsalted butter for baking dish, plus 2 Tbs.
- Canola oil for frying, plus 1 Tbs.
- 3/4 cup all-purpose flour
- Kosher salt and freshly ground black pepper, to taste
- Cayenne pepper, to taste
- 6 large shallots, peeled and sliced into thin rings
- 1 lb. cremini mushrooms, sliced
- 1/4 cup finely chopped shallots
- 1 cup chicken stock
- 1 cup heavy cream
- 2 lb. green beans, trimmed, halved and blanched
Preheat an oven to 375°F. Butter a 13-by-9-inch baking dish.
In a 4-quart saucepan over medium-high heat, pour in oil to a depth of 1 inch and heat to 350°F on a deep-frying thermometer. Line a baking sheet with paper towels.
Put 1/2 cup of the flour in a small bowl and season with salt, black pepper and cayenne. Add the sliced shallots and toss to coat evenly. Working in batches, fry the shallots until golden brown and lightly crisped, 5 to 6 minutes. Transfer to the prepared baking sheet and lightly season with salt. Set aside.
In a large sauté pan over medium-high heat, warm the 1 Tbs. oil and melt the 2 Tbs. butter. Add the mushrooms and cook, stirring occasionally, until well browned, 6 to 8 minutes. Reduce the heat to medium, add the chopped shallots and cook, stirring occasionally, until softened, 2 to 3 minutes. Add the remaining 1/4 cup flour and cook, stirring constantly, until fragrant, about 1 minute. While stirring constantly, slowly add the stock and then the cream. Bring to a simmer and cook, stirring occasionally, until thickened, 3 to 4 minutes. Add the green beans and season with salt and black pepper. Transfer to the prepared baking dish and sprinkle the fried shallot rings on top.
Transfer to the oven and bake until the edges are bubbling and the top is browned, about 30 minutes. Let rest for 5 to 10 minutes before serving. Serves 8.
