Preheat your oven to 425°F (220°C) and line a large sheet pan with parchment paper.
Pat the chicken thighs thoroughly dry with paper towels to ensure the skin gets maximum crispiness.
In a small bowl, mince the garlic, rosemary, and thyme, then combine with half of the olive oil, sea salt, and black pepper.
Rub the herb oil mixture all over the chicken thighs, making sure to get some under the skin.
Place the chicken on the sheet pan and roast for 15 minutes.
While chicken is roasting, trim the woody ends off the asparagus and halve the radishes.
Toss the asparagus and radishes with the remaining olive oil and a squeeze of lemon juice.
Add the vegetables to the sheet pan around the chicken and roast for another 12-15 minutes until the chicken reaches an internal temperature of 165°F and the vegetables are tender.
Serve immediately with the remaining lemon wedges for an extra pop of brightness.
