Preheat the oven to 425°F (220°C). Line a baking sheet with silicone mat, or parchment paper.
Wash and peel (if desired) the potatoes. Cut them in half lengthwise. Cut the bacon strips in half as well.
Spread about ½ teaspoon or so pesto on the fingerling potatoes and wrap the bacon around them. Place the seam side down on prepared baking sheet. Bake for about 25 minutes, or until the bacon is cooked.
Serve at room temperature with pesto sauce on the side, if desired.
