Preheat your oven to 400°F and line a large sheet pan with parchment paper for easy cleanup.
Dice the yellow potato into 1-inch cubes and trim the tough, woody ends off the asparagus spears.
In a small bowl, whisk together the olive oil, minced garlic, rosemary, thyme, sea salt, and black pepper.
Place the chicken breast, cubed potatoes, and asparagus on the prepared baking sheet.
Drizzle the garlic-herb mixture over the chicken and vegetables, tossing the produce to ensure an even coating.
Roast in the center of the oven for 20 to 25 minutes, or until the chicken reaches an internal temperature of 165°F and the potatoes are golden and fork-tender.
Remove from the oven and squeeze the fresh lemon juice over the entire tray to brighten the savory roasted flavors before serving.
