Preheat your oven to 425°F and line a baking sheet with parchment paper for easy cleanup.
Pat the chicken breast completely dry with paper towels to ensure the skin achieves maximum crispiness.
In a small bowl, whisk together the sea salt, black pepper, dried thyme, garlic powder, onion powder, and smoked paprika.
Rub the ghee evenly over the chicken skin, then coat thoroughly with the prepared herb seasoning blend.
Place the chicken on the baking sheet and roast for 15 minutes.
While the chicken roasts, trim the woody ends off the asparagus and halve the cherry tomatoes.
Remove the pan from the oven, arrange the asparagus and tomatoes around the chicken, and return to the oven for another 10-12 minutes.
Check that the chicken has reached an internal temperature of 165°F and the vegetables are tender and slightly charred.
Drizzle the fresh lemon juice over the entire dish before serving to brighten the savory flavors.
