Preparation Remove zest from lemon in 1-inch-wide strips with a vegetable peeler. Cut off any white pith from zest with a small sharp knife. Halve lemon and set aside. Heat oil and zest in a 5-quart wide heavy pot over moderate heat until zest is golden, about 3 minutes. Remove from heat and discard zest, reserving oil in pot. Cook Broccolini in an 8- to 10-quart pot two-thirds full of boiling salted water , uncovered, until crisp-tender, 5 to 7 minutes. Drain well in a large colander. Reheat lemon oil over moderately high heat until hot but not smoking. Add Broccolini and cook, tossing, until coated well and heated through, about 1 minute. Add salt and pepper to taste, then squeeze half of lemon over Broccolini. (Reserve remaining lemon half for another use.)
