Preserved lemons add a wonderful salty-sweet hit to these simple potatoes, but if you don’t have them on hand, you can use regular lemons instead. Thinly slice the peel of one lemon, then toss with the potatoes before roasting.
2 pounds fingerling potatoes, halved lengthwise
3 tablespoons olive oil
2 teaspoons chopped fresh rosemary
Kosher salt and freshly ground black pepper
3 tablespoons thinly sliced preserved lemon peel
Preheat oven to 450°. Toss potatoes, oil, and rosemary on a large rimmed baking sheet; season with salt and pepper. Roast, tossing halfway through, until soft and golden brown, 25–30 minutes. Toss warm potatoes with preserved lemon peel.
