Following these simple steps will help you create the perfect Garlic Herb Chicken with Mashed Potatoes and Glazed Carrots:

1. Preheat the Oven: Start by preheating your oven to 400°F (200°C).
2. Prepare Chicken: In a small bowl, mix together garlic, olive oil, rosemary, thyme, salt, and pepper.
3. Season Chicken: Spread the mixture evenly over the chicken breasts, ensuring they are well-coated.
4. Bake Chicken: Place the chicken breasts in a baking dish and bake for 25-30 minutes, or until the internal temperature reaches 165°F (75°C).
5. Cook Potatoes: While chicken bakes, place potatoes in a large pot of salted water. Bring to a boil and cook until tender, about 15-20 minutes.
6. Prepare Glazed Carrots: In a sauté pan over medium heat, add the baby carrots, butter, and brown sugar. Cook, stirring frequently, until the carrots are tender and glazed, about 10-12 minutes.
7. Mash Potatoes: Drain the potatoes and return them to the pot. Add milk and salt, mashing until smooth and creamy.
8. Rest Chicken: Remove chicken from the oven and let it rest for 5-10 minutes before slicing.
9. Plate the Dish: On each plate, arrange a portion of mashed potatoes, a serving of glazed carrots, and sliced chicken.
10. Garnish: Finish with a sprinkle of freshly chopped parsley for a pop of color.

This straightforward process will lead you to a beautifully crafted dinner!
