Preheat your oven to 400°F (200°C) and line a large sheet pan with parchment paper for easy cleanup.
Pat the chicken breast completely dry with paper towels to ensure the skin or surface gets crispy.
Halve the baby potatoes and mince the garlic clove.
In a small bowl, whisk the olive oil, minced garlic, chopped rosemary, and thyme.
Place the chicken and potatoes on the sheet pan, then drizzle with two-thirds of the herb oil, sea salt, and black pepper, tossing to coat.
Arrange the chicken in the center and the potatoes around it, then roast in the oven for 15 minutes.
While the chicken is roasting, trim the woody ends off the asparagus and slice the lemon into thin rounds.
Remove the pan from the oven, add the asparagus and lemon slices, and drizzle with the remaining herb oil.
Return the pan to the oven for another 10 to 12 minutes until the chicken reaches an internal temperature of 165°F and the potatoes are golden brown.
Let the chicken rest for 5 minutes before slicing to keep it juicy.
