Preheat the oven: Set oven to 400°F (200°C) and line a large rimmed sheet pan with parchment paper or foil.
Prep the potatoes: Toss the halved baby potatoes with olive oil, garlic powder, salt, and pepper. Spread on one-third of the sheet pan.
1½ pounds baby potatoes, 2 tablespoons olive oil, 1 teaspoon garlic powder, 1 teaspoon Fine salt, ½ teaspoon Black pepper
Season the chicken: Nestle the chicken thighs in the center of the pan. Sprinkle with paprika, salt, and pepper. Brush both sides with BBQ sauce.
6 bone-in, 1 teaspoon paprika, ¾ cup BBQ sauce
Add the veggies: Place the green beans and mini corn on the cob on the remaining third of the pan. Drizzle with olive oil and season lightly with salt.
12 ounces green beans, 3 mini corn on the cob
Roast everything: Bake for 30–35 minutes, until the chicken reaches 165°F, the skin is golden and crisp, the potatoes are tender, and the corn lightly roasted.
Finish strong: For extra caramelized chicken, broil just the chicken for 2–3 minutes. Garnish with parsley before serving.
Optional garnish: chopped fresh parsley
