Toss the halved new potatoes and fennel wedges on the prepared sheet pan with 2 tablespoons of the olive oil, 1/2 teaspoon of the salt, and 1/4 teaspoon of the black pepper until evenly coated. Spread in a single layer, cut sides down. Roast for 20 minutes, until the potatoes are just beginning to turn golden at the edges and the fennel is softened.
