Heat your oven to 425°F and lightly coat a large baking sheet with olive oil to prevent sticking.

Give the potatoes a good wash and pat them completely dry with a clean kitchen towel. Cut each potato in half, and if you have any larger ones, quarter them so all pieces are roughly the same size for even roasting.

Toss the potato pieces in a large mixing bowl with the pesto, grated Parmesan, and a generous pinch of salt and pepper. Make sure every piece gets nicely coated with that herby pesto goodness.

Arrange the potatoes on your prepared baking sheet with the cut sides facing down, giving each piece some breathing room. Roast for 20 minutes, then give them a gentle stir and continue cooking for another 5-10 minutes until they're beautifully golden and tender when pierced with a fork. Finish with an extra drizzle of pesto and a sprinkle of Parmesan before serving.
