Preheat your oven to 400°F and line a large rimmed baking sheet with parchment paper for easy cleanup.
Pat the chicken breast completely dry with a paper towel to ensure the surface achieves a beautiful golden-brown sear.
In a small bowl, whisk together the olive oil, minced garlic, chopped rosemary, thyme, lemon juice, sea salt, and black pepper.
Halve the baby potatoes and trim the woody ends off the asparagus spears.
Place the chicken and potatoes on the baking sheet, drizzling with the herb oil and tossing the potatoes to coat evenly.
Roast for 12 minutes, then add the asparagus to the pan, tossing them in the remaining juices.
Continue roasting for 10-12 minutes until the chicken reaches an internal temperature of 165°F and the potatoes are fork-tender.
Allow the chicken to rest for 5 minutes before slicing to ensure every bite remains incredibly succulent.
