Ingredients

Scale
  • pounds boneless, skinless chicken breasts
  • 4 cups fresh broccoli florets, washed and dried
  • 3 tablespoons extra virgin olive oil
  • 2 tablespoons fresh lemon juice (about 1 large lemon)
  • 1 teaspoon lemon zest
  • 2 teaspoons dried Italian herbs (or 1 tablespoon fresh chopped rosemary, thyme, and oregano)
  • 3 cloves garlic, minced
  • 1 teaspoon salt
  • ½ teaspoon freshly ground black pepper
  • Optional: red pepper flakes for heat
  • Optional: Parmesan cheese for sprinkling before serving

Instructions

  1. Preheat your oven to 425°F (220°C).
  2. Trim any excess fat from the chicken breasts and pat them dry with paper towels.
  3. In a mixing bowl, combine olive oil, fresh lemon juice, lemon zest, minced garlic, dried Italian herbs, salt, and black pepper. Whisk until well combined.
  4. Add the chicken breasts to the bowl and toss until evenly coated with the lemon herb mixture. Let sit for about 5 minutes (or up to 15 minutes for extra flavor).
  5. Add the broccoli florets to the same bowl and toss gently with any remaining lemon herb mixture.
  6. Spread the broccoli evenly on one side of a parchment-lined baking sheet.
  7. Place the chicken breasts on the other side of the baking sheet, spacing pieces apart.
  8. Roast in the oven for 20–25 minutes. Halfway through (around 12 minutes), use tongs to turn the chicken and toss the broccoli for even roasting.
  9. Check that the chicken reaches an internal temperature of 165°F (74°C) and juices run clear.
  10. Optional: Sprinkle freshly grated Parmesan over the hot broccoli and chicken after removing from the oven.
  11. Let rest for 5 minutes before serving.

Notes

Make sure broccoli florets are completely dry before roasting to avoid steaming. Do not overcrowd the pan to ensure proper roasting and caramelization. Use a meat thermometer to check chicken doneness at 165°F (74°C). If oven runs hot, tent loosely with foil after 15 minutes to prevent burning. For dairy-free option, skip Parmesan or use nutritional yeast.
