Green Beans with Brown Butter and Toasted Hazelnuts

Bring 2 1/2 quarts water to boil in a large saucepan over high heat; add salt and green beans, return to boil, and cook until beans are bright green and crisp-tender, 3 to 4 minutes. Meanwhile, fill large bowl with ice water. Drain beans in colander and transfer beans immediately to ice water. When beans no longer feel warm to touch, drain in colander again and dry thoroughly with paper towels.

Heat butter in small heavy-bottomed saucepan over medium heat and cook, swirling frequently, until butter turns deep chocolate brown and becomes fragrant, 4 to 5 minutes. Add hazelnuts and cook, stirring constantly, until fragrant and combined, about 1 minute. Season with salt and pepper to taste.

Meanwhile, heat 1/4 cup water and beans in 12-inch skillet over high heat; cook, tossing frequently, until beans are warmed through, about 1 to 2 minutes. Season with salt and pepper to taste and arrange neatly on a warm serving platter. Top beans with toasted hazelnuts and brown butter and serve immediately.
