Ingredients
  

Main Ingredients

  • 1.5 lbs Boneless, Skinless Chicken Breasts or Thighs (about 4 pieces)
  • 2 tablespoons Lemon Pepper Seasoning
  • 2 Fresh Lemons (1 for juice/zest, 1 for slicing)
  • 3 tablespoons Olive Oil
  • 1 teaspoon Garlic Powder
  • 0.5 teaspoon Salt (or to taste, adjust based on seasoning)
  • 0.25 teaspoon Black Pepper (freshly ground)
  • 3 cups Broccoli Florets
  • 1 cup Cherry Tomatoes
  • 1 Red Onion small, cut into wedges
  • Fresh Parsley or Chives For garnish (optional)

Instructions
 

Preparation

  • Pat chicken dry and optionally slice breasts horizontally or pound to 1/2-inch thickness for even cooking.
  • Whisk olive oil, lemon juice, lemon pepper seasoning, garlic powder, salt, and black pepper; coat chicken and marinate for 15-30 minutes.
  • Preheat oven to 400°F (200°C) and line a baking sheet with parchment paper. Toss broccoli, cherry tomatoes, and red onion with olive oil, salt, and pepper in a separate bowl.
  • Arrange chicken on one side of the baking sheet and vegetables on the other; add lemon slices on top.
  • Bake for 20-25 minutes, or until chicken reaches 165°F (74°C) and vegetables are tender-crisp.
  • Remove from oven, rest chicken for 5 minutes, then slice. Garnish with parsley or chives, and serve immediately with roasted vegetables.

Notes

For extra flavor, consider marinating the chicken for a longer period, up to a few hours in the refrigerator. Adjust seasoning amounts to your personal preference. Ensure vegetables are not overcrowded on the baking sheet for optimal roasting; use two sheets if necessary.
