Crispy, spice-rubbed chicken thighs roast on a single pan alongside bell-pepper strips and zucchini rounds, soaking up smoky chili, bright lime, and garlicky goodness as they sizzle.
Prep the dry rub: Mix chili powder, cumin, garlic powder, salt, and pepper.
Season chicken: Pat thighs dry, coat with oil, then rub spice mix all over (under skin if possible).
Arrange sheet pan: Spread peppers & zucchini on a rimmed pan. Drizzle with 1 Tbsp oil and toss with a pinch of salt. Nestle thighs skin-side up on top; squeeze 1 lime over everything.
Bake: Roast at 425°F (220°C) for 35-40 min until chicken hits 175°F and skin is deep golden. Broil 2 min for extra crisp.
Finish: Rest 5 min. Sprinkle cilantro and serve with lime wedges.
