Equipment

  • large sheet pan
  • parchment paper optional
  • large mixing bowl
  • meat thermometer to check 165°F internal temperature
  • tongs or spatula

Ingredients
  

  • 4 boneless, skinless chicken breasts
  • 1 large head of broccoli, cut into florets
  • 1 red bell pepper, sliced
  • 1 yellow bell pepper, sliced
  • 1 cup cherry tomatoes, halved
  • 2 tbsp olive oil
  • 2 tbsp Dijon mustard
  • 1 tsp salt
  • 1/2 tsp black pepper
  • 1 tbsp lemon juice (optional)

Instructions
 

  • Preheat your oven to 400°F (200°C). Line a large sheet pan with parchment paper or lightly grease with olive oil. Place the chicken breasts on the pan and season with salt and pepper. Brush each breast generously with Dijon mustard.
  • In a large bowl, toss broccoli florets, bell pepper slices, and cherry tomatoes with olive oil, salt, and pepper. Spread the vegetables evenly around the chicken on the sheet pan in a single layer.
  • Roast for 25–30 minutes, flipping the vegetables halfway through. Chicken is done when it reaches 165°F (74°C) internally, vegetables are tender, and tomatoes have burst.
  • Remove from the oven and drizzle with fresh lemon juice if desired. Let the chicken rest for 5 minutes before serving.

Notes

For juicier meat, swap chicken breasts with chicken thighs. Add zucchini, mushrooms, or asparagus for variety. Sprinkle paprika, garlic powder, or Italian herbs for extra flavor. Let chicken rest 5 minutes before slicing to retain juices. Avoid overcrowding the pan to keep vegetables crisp-tender. Optional: finish with fresh lemon juice or grated Parmesan before serving.
