Lemon-Parmesan Crispy Smashed Potatoes

Position rack in lower third of oven; preheat to 450°F.

Place potatoes in a large pot, cover with water and bring to a boil. Cook, covered, until fork-tender, about 15 minutes. Drain.

Drizzle 1 tablespoon oil on a large rimmed baking sheet. Add the potatoes and, using the bottom of a glass coated with cooking spray, gently smash each potato to flatten. Drizzle with the remaining 1 tablespoon oil and sprinkle with salt and pepper. Scatter garlic on the pan.

Bake the potatoes, flipping once halfway, until crispy, about 20 minutes. Sprinkle with Parmesan and lemon zest.
