Preheat your oven to 400°F and line a large rimmed baking sheet with parchment paper for easy cleanup.
Mince the garlic cloves and finely chop the fresh rosemary and thyme leaves.
In a small mixing bowl, whisk together the extra virgin olive oil, lemon juice, lemon zest, minced garlic, rosemary, thyme, turmeric, sea salt, and black pepper.
Place the chicken thighs on the prepared baking sheet and brush half of the lemon-herb marinade evenly over both sides of the meat.
Roast the chicken in the center of the oven for 15 minutes.
While the chicken is roasting, trim the woody ends off the asparagus spears.
Remove the baking sheet from the oven and arrange the asparagus in a single layer around the chicken thighs.
Drizzle the remaining marinade over the asparagus and toss lightly with tongs to coat.
Return the pan to the oven and roast for another 12 to 15 minutes until the chicken reaches an internal temperature of 165°F and the asparagus is tender.
Let the chicken rest for 5 minutes before serving to allow the juices to settle.
