Ingredients

Scale
  • 5 boneless, skinless chicken breasts (about 6 oz / 170 g each)
  • 2 cups broccoli florets (fresh or frozen)
  • 2 cups chopped bell peppers (red or yellow)
  • 1 medium red onion, sliced into wedges
  • 1 cup cherry tomatoes (optional)
  • 2 tablespoons olive oil
  • 1 teaspoon smoked paprika
  • 1 teaspoon garlic powder
  • 1 teaspoon dried oregano or Italian seasoning
  • Salt to taste (about 1 teaspoon)
  • Freshly ground black pepper to taste (about ½ teaspoon)
  • 1 tablespoon lemon juice (optional)
  • Red pepper flakes (optional)

Instructions

  1. Preheat your oven to 425°F (220°C) and line your sheet pan with parchment paper.
  2. Pat the chicken breasts dry with paper towels and place them in a large mixing bowl.
  3. In a small bowl, combine olive oil, smoked paprika, garlic powder, oregano, salt, black pepper, and lemon juice if using. Pour over chicken and toss well to coat evenly.
  4. Toss broccoli, bell peppers, onion wedges, and cherry tomatoes with a drizzle of olive oil, a pinch of salt, and pepper.
  5. Spread the chicken breasts on one side of the sheet pan, leaving space between each piece. Spread the veggies evenly on the other side in a single layer.
  6. Roast in the oven for 20 minutes. Halfway through (around 10 minutes), flip the chicken and stir the veggies for even cooking.
  7. Check that the chicken has reached an internal temperature of 165°F (74°C) and that the veggies are tender and caramelized.
  8. Let the chicken rest for 5 minutes before slicing. Divide chicken and veggies evenly into 5 meal prep containers.

Notes

Pat chicken dry before seasoning for better browning. Avoid overcrowding the pan to ensure proper roasting. Use an oven thermometer for consistent temperature. Chicken thighs can be used but may require longer cooking time. For vegetarian option, substitute chicken with pressed tofu or tempeh.
