Ingredients

Instructions

  1. Step 1: Preheat oven to 425°F (220°C). In a small bowl, whisk together 2 tbsp olive oil, 3 minced garlic cloves, 1 tsp fresh rosemary, 1 tsp fresh thyme, zest and juice of 1 lemon, 1/2 tsp salt, and 1/4 tsp black pepper.
  2. Step 2: Place 12 oz chicken breasts on a parchment-lined baking sheet. Drizzle with half the lemon-herb mixture, then rub to coat evenly; set aside.
  3. Step 3: Toss 1 cup sliced bell peppers, 1 cup sliced zucchini, 1/2 cup sliced red onion, and 1 cup cherry tomatoes with the remaining lemon-herb mixture until all vegetables are evenly coated.
  4. Step 4: Arrange the coated vegetables around the chicken on the baking sheet, spreading in a single layer without overcrowding.
  5. Step 5: Roast for 25-30 minutes, or until the chicken reaches an internal temperature of 165°F (74°C) and the vegetables are tender with slightly charred edges, stirring once halfway through.
