Instructions

  1. Step 1: Preheat oven to 425°F and line a large sheet pan with foil. In a small bowl, whisk together 3 tbsp olive oil, 2 tbsp lemon juice, 1 tsp lemon zest, 1 tsp garlic powder, 1 tsp ground black pepper, 1 tsp sea salt, and 1/2 tsp dried oregano.
  2. Step 2: Place 4 boneless skinless chicken breasts on the sheet pan and brush them generously with half of the lemon-olive oil mixture. Add 4 cups broccoli florets and 2 cups cherry tomatoes to the pan and drizzle with the remaining lemon-olive oil mixture along with 1/2 tsp sea salt. Toss the vegetables gently to coat.
  3. Step 3: Roast everything for 20-25 minutes until the chicken is cooked through (internal temperature 165°F) and the broccoli is tender with some charred edges. Serve immediately garnished with additional lemon wedges if desired.
