01 - Preheat the oven to 400°F. Lightly grease a large baking dish or sheet pan with olive oil or cooking spray.
02 - In a medium mixing bowl, whisk together the honey, lemon juice, lemon zest, olive oil, minced garlic, dried thyme, oregano, salt, and black pepper until well combined.
03 - Place the chicken thighs and halved baby potatoes in the prepared baking dish. Tuck the red onion wedges among them.
04 - Pour the honey-lemon glaze evenly over the chicken and potatoes, tossing everything to ensure an even, thorough coating.
05 - Arrange the chicken thighs skin-side up and spread the potatoes in a single, even layer around the chicken for optimal browning.
06 - Bake for 40–45 minutes until the chicken reaches an internal temperature of 165°F and the potatoes are golden and fork-tender.
07 - For a crispier finish, broil on high for 2–3 minutes, keeping a close eye to prevent burning.
08 - Remove from the oven, garnish with freshly chopped parsley and lemon slices, and serve immediately.
