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, dried 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 around them in an even layer.
04 - Pour the honey-lemon glaze evenly over the chicken and potatoes. Toss everything well to ensure an even, thorough coating.
05 - Arrange the chicken thighs skin-side up and spread the potatoes into a single layer around the chicken for uniform 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 crispy, caramelized finish, switch the oven to broil for 2–3 minutes. Watch closely to prevent burning.
08 - Remove from the oven and garnish with freshly chopped parsley and lemon slices. Serve immediately while hot.
