Preheat oven to 400°F (200°C). Prepare a baking sheet with parchment paper.
In a bowl, mix olive oil, minced garlic, chopped rosemary, thyme, lemon juice, salt, and pepper. Marinate the chicken for at least 15 minutes.
Place the marinated chicken on the prepared baking sheet. Arrange asparagus spears around the chicken.
Roast in the preheated oven for 30-40 minutes, or until the chicken is cooked through and the asparagus is tender-crisp.
While the chicken and asparagus are roasting, boil sweet potatoes until tender. Drain and mash with butter, milk, salt, and pepper.
Serve the roasted chicken and asparagus with a side of mashed sweet potatoes. Garnish with fresh herbs if desired.
Let it cool down and serve it
