Ingredients

1 whole organic chicken (about 3 1/2 pounds)

1/4 cup extra-virgin olive oil

Coarse salt and freshly ground pepper

1/2 cup finely chopped flat-leaf parsley

1 lemon, halved

1 pound fingerling potatoes, halved or cut into thirds if large

2 cloves garlic, minced

1/2 cup finely chopped flat-leaf parsley

1/2 cup extra-virgin olive oil

1 lemon, zested (2 teaspoons) and juiced (1 1/2 tablespoons)

1/2 cup grated Parmesan cheese

1/2 teaspoon coarse salt

Pinch of red-pepper flakes

Preparation

Preheat oven to 425 degrees. Place chicken, breast side up, on a baking sheet. Rub with 2 tablespoons oil; season generously with salt and pepper. Place parsley and 1 lemon half in cavity. Tie legs together with kitchen twine.

Toss potatoes and 2 tablespoons oil. Drizzle with juice from remaining lemon half. Season with salt and pepper. Scatter potatoes along chicken.

Roast for 15 minutes. Reduce temperature to 375 degrees; cook for 25 minutes. Rotate pan, toss potatoes, and cook until potatoes and chicken are golden brown and a thermometer inserted into the thickest part of the chicken’s thigh reaches 165 degrees, about 25 minutes more. Let chicken and potatoes stand for 10 minutes.

Meanwhile, make the sauce: Combine ingredients. After 10 minutes, brush sauce on chicken and drizzle on potatoes.
