This broccoli rabe with roasted garlic is mellowed by sweet, roasted garlicky goodness and spiked with the warmth of red pepper flakes. An easy side dish for weeknight dinners. Here's how to prepare it.
Break the head of garlic into individual cloves but do not peel them. Stack 2 pieces of aluminum foil, each about 6 inches square, on top of one another. Pile the garlic cloves in the center of the foil, drizzle with the olive oil, and sprinkle with salt and black pepper Bring up the corners of the foil and crimp together to make a tightly sealed little package. Roast until the garlic cloves feel soft and yielding when you gently pinch them, 30 to 40 minutes. Let the garlic cool slightly.
When the garlic is cool enough to handle, pinch the tip of each clove to squeeze the mushy goodness from the papery skins. Discard the skins but reserve the garlic oil in the foil.
Make the broccoli rabe
Meanwhile, trim and discard the tough stem ends from the broccoli rabe. Place the rabe in a large saucepan and add the water. Cover the pan and bring to a boil. Reduce the heat to medium-low and cook until the broccoli rabe is tender and bright green, about 5 minutes. Drain and pat the broccoli rabe dry. If desired, cut it into 1-inch lengths.
In a large skillet over medium heat, warm the olive oil. Add the roasted garlic, any oil from the foil package, and the red pepper flakes, if desired, and saute for 3 to 4 minutes. Add the broccoli rabe, stir to combine, and saute just until heated through, about 3 minutes. Season to taste with salt and black pepper.
