In a large mixing bowl, combine olive oil, lemon zest, lemon juice, minced garlic, dried oregano, dried thyme, smoked paprika, salt, and pepper. Whisk until well blended.
Add the chicken thighs to the bowl and coat thoroughly with the marinade. Set aside to marinate for about 15 minutes while you prepare the potatoes.
In another bowl, toss the quartered potatoes with a little olive oil, salt, and pepper until they're well coated.
Spread the marinated chicken thighs in a single layer on one side of a large, rimmed baking sheet. Add the seasoned potatoes alongside, making sure they’re spread out for even cooking.
Bake in the preheated oven for about 30 minutes, or until the chicken is cooked to an internal temperature of 165°F (74°C) and the potatoes are golden and tender.
Remove from the oven and let sit for a few minutes. Garnish with fresh parsley before serving.
Notes
Let the chicken marinate for at least 15 minutes for better flavor.
