How to Make It
Bring a large pot of salted water to a boil. Add the Broccolini and cook until bright green and barely crisp-tender, about 5 minutes. Drain, reserving 1/2 cup of the cooking water.
In a very large skillet, heat the olive oil with the garlic and crushed red pepper and cook over moderate heat until fragrant, about 1 minute. Increase the heat to high, add the Broccolini and toss to coat with the oil. Add the reserved cooking water and toss occasionally, until the Broccolini is crisp-tender, about 2 minutes. Season with salt and transfer to a platter. Serve warm or at room temperature.
