Step 1: Preheat the Oven: Preheat the oven to 400F (200C). Ensure the oven rack is positioned in the center.
Step 2: Prepare the Vegetables: In a large bowl, combine the cubed potatoes, red onion wedges, and chopped carrots. Add the minced garlic, olive oil, dried rosemary, dried thyme, salt, and pepper. Toss well to ensure the vegetables are evenly coated with the oil and seasonings.
Step 3: Arrange Vegetables in Baking Dish: Spread the seasoned vegetables in a single layer in a 9x13 inch baking dish. Ensure the vegetables cover the base of the dish evenly.
Step 4: Place Chicken on Vegetables: Arrange the chicken breasts on top of the vegetables. Ensure the chicken is evenly spaced and not overlapping.
Step 5: Add Chicken Broth: Pour the chicken broth into the baking dish, around the chicken and vegetables. The broth should reach about halfway up the vegetables.
Step 6: Bake: Cover the baking dish tightly with aluminum foil. Bake in the preheated oven for 30 minutes.
Step 7: Remove Foil and Continue Baking: Remove the aluminum foil and continue baking for an additional 15 minutes, or until the chicken is cooked through and the vegetables are tender. The internal temperature of the chicken should reach 165F (74C).
Step 8: Rest and Garnish: Remove the baking dish from the oven and let it rest for 5 minutes before serving. Garnish with fresh parsley, if desired.
Optional Tips: For a richer flavor, consider using bone-in, skin-on chicken thighs instead of chicken breasts. Adjust baking time accordingly. Substitute any of the vegetables with your favorites, such as Brussels sprouts, sweet potatoes, or bell peppers. A squeeze of lemon juice over the chicken and vegetables before serving adds brightness.
