Brocollini with Pecan Brown Butter

Makes 10 servings

2 1/4 to 2 1/2 pounds broccolini (about 4 bunches)
6 tablespoons (3/4 stick) butter
1/4 cup finely chopped shallots (about 2 medium)
1 garlic clove, chopped
1/2 cup toasted pecans , coarsely chopped
Coarse kosher salt

Bring large pot of salted water to boil. Add broccolini; stir to separate and cook 2 minutes. Drain. Transfer broccolini to paper towels to drain. Cool. DO AHEAD: Can be made 1 day ahead. Wrap broccolini in several layers of clean paper towels; enclose in resealable plastic bag and chill.

Melt butter in extra-large skillet over medium heat. Add shallots and garlic, then pecans; sauté until shallots are soft, about 3 minutes. Increase heat to medium-high; stir constantly until butter is browned and pecans are aromatic, about 3 minutes. Add broccolini to skillet and toss gently until heated through, about 7 minutes. Season to taste with coarse salt and pepper. Transfer to platter and serve.
