Preheat your oven to 400°F and line a large sheet pan with parchment paper for easy cleanup.
Pat the chicken breast dry with a paper towel to ensure the skin gets crispy, then rub with half of the olive oil.
In a small bowl, combine the lemon zest, dried rosemary, dried thyme, sea salt, and black pepper.
Season both sides of the chicken breast generously with the herb mixture and place it on one side of the prepared sheet pan.
Toss the halved baby potatoes with the remaining olive oil, minced garlic, and lemon juice in a bowl until well coated.
Arrange the potatoes on the other side of the sheet pan and roast for 15 minutes.
Remove the pan from the oven, add the trimmed asparagus spears to the center, and roast for an additional 10 to 12 minutes.
Ensure the chicken reaches an internal temperature of 165°F and the potatoes are golden-brown before removing from the oven.
Let the chicken rest for 5 minutes before slicing to keep it juicy and tender.
