Step 1: Preheat Oven and Prepare Baking Sheet: Preheat the oven to 400F (200C). Line a large baking sheet with parchment paper for easy cleanup.
Step 2: Prepare the Vegetables: In a large bowl, combine the quartered red potatoes, onion wedges, chopped carrots, and bell peppers. Drizzle with olive oil and toss to coat evenly.
Step 3: Season the Vegetables: Sprinkle the Italian herbs, garlic powder, salt, and pepper over the vegetables. Toss again to ensure the vegetables are well seasoned.
Step 4: Arrange Vegetables on Baking Sheet: Spread the seasoned vegetables in a single layer on the prepared baking sheet.
Step 5: Prepare the Chicken: Pat the chicken breasts dry with paper towels. Place the chicken breasts on top of the vegetables on the baking sheet, spacing them evenly.
Step 6: Season the Chicken: Sprinkle the remaining Italian herbs, garlic powder, salt, and pepper evenly over the chicken breasts.
Step 7: Bake: Place the baking sheet in the preheated oven and bake for 35-40 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 Serve: Remove the baking sheet from the oven and let the chicken and vegetables rest for 5 minutes before serving. Garnish with lemon wedges, if desired.
Tips and Substitutions:
- Other vegetables such as broccoli florets, zucchini, or asparagus can be used. Adjust cooking time accordingly.
- Chicken thighs can be substituted for chicken breasts; they may require a slightly longer cooking time.
- For a spicier dish, add a pinch of red pepper flakes to the vegetable mixture.
