Rinse the rabe under cold water then trim it by cutting off the bottoms by about 1/2 an inch.
Heat the olive oil in a large skillet over medium heat. Scatter the garlic over the oil and cook, shaking the pan, until golden brown, about 1 minute. Carefully lay the broccoli rabe into the oil, season lightly with salt and 1/4 teaspoon crushed red pepper. Stir and toss to distribute the seasonings. Cover the rabe so it steams a little bit and then taste and adjust your salt and pepper seasonings.
