- Step 1: Preheat Oven: Preheat the oven to 400F (200C). Ensure the oven rack is positioned in the center. 
- Step 2: Prepare Vegetables: In a large bowl, combine the quartered red potatoes, red onion wedges, sliced carrots, and zucchini pieces. 
- Step 3: Season Vegetables: Add minced garlic, chopped rosemary, thyme, olive oil, salt, and pepper to the bowl with the vegetables. Toss thoroughly to ensure even coating. 
- Step 4: Arrange in Baking Dish: Spread the seasoned vegetables evenly in a large baking dish (approximately 9x13 inches). 
- Step 5: Prepare Chicken: Pat the chicken thighs dry with paper towels. This helps achieve crispy skin. 
- Step 6: Season Chicken: In a small bowl, whisk together the lemon juice, remaining olive oil (if any), salt, and pepper. Rub the mixture evenly over the chicken thighs, ensuring they are well-coated. 
- Step 7: Arrange Chicken: Arrange the chicken thighs on top of the vegetables in the baking dish. Tuck lemon slices in between the chicken pieces and vegetables. 
- Step 8: Bake: Bake in the preheated oven for 45 minutes, or until the chicken is cooked through and the internal temperature reaches 165F (74C). The vegetables should be tender and slightly browned. 
- Step 9: Rest (Optional): Let the dish rest for 5-10 minutes before serving. This allows the juices to redistribute, resulting in more flavorful and tender chicken. 
- Optional Tips: For extra crispy chicken skin, broil for the last 2-3 minutes, watching carefully to prevent burning. Vegetables can be substituted based on preference or availability; bell peppers, asparagus, or Brussels sprouts work well. Dried herbs can be used in place of fresh, use about 1 teaspoon of each.
