One of my all-time favorites, this sheet-pan supper has it all—spicy harissa-laced roasted chicken; sweet, browned leeks; crunchy potatoes; plus a cool garnish of salted yogurt and plenty of fresh bright herbs. It’s a little lighter than your average roasted chicken and potatoes dinner, and a lot more profoundly flavored.
The key here (and with all sheet-pan suppers) is to make sure the ingredients can all cook together on the same pan. This means cutting sturdy, denser things into smaller chunks that will cook at the same rate (chicken, potatoes), and adding the more delicate ingredients (here, the leeks) toward the end so they don’t burn. Another important note: don’t overpopulate the pan. You need to leave space between things so ingredients can brown and crisp rather than steam. If you want to double the recipe to feed six, you can, as long as you spread everything out in two pans rather than crowding them in one.
Combine the chicken and potatoes in a large bowl. Season them with 2½ teaspoons of the salt and ½ teaspoon of the pepper. In a small bowl, whisk together the harissa, cumin, and 3 tablespoons of the olive oil. Pour this mixture over the chicken and potatoes, and toss to combine. Let it stand at room temperature for 30 minutes.
Meanwhile, in a medium bowl, combine the leeks, lemon zest, ¼ teaspoon of the salt, and the remaining 1½ tablespoons olive oil.
Heat the oven to 425°F.
Arrange the chicken and potatoes in a single layer on a large rimmed baking sheet, and roast for 20 minutes. Then toss the potatoes lightly, and scatter the leeks over the baking sheet. Roast until the chicken is cooked through and everything is golden and slightly crisped, 20 to 25 minutes longer.
While the chicken cooks, place the yogurt in a small bowl. Grate the garlic clove over the yogurt, and season with the remaining ¼ teaspoon salt and ¼ teaspoon pepper.
Spoon the yogurt over the chicken and vegetables in the baking sheet (or you can transfer everything to a platter if you want to be fancy about it). Scatter the herbs over the yogurt, drizzle some olive oil and lemon juice over the top, and serve.
