Equipment

  • Large rimmed sheet pan (about 12 x 18 inches) or a 9 x 13-inch baking dish

Ingredients

Chicken and veggies

  • 2 lb chicken thighs (boneless thighs can also be used; they may cook faster)
  • 1 lb potatoes cut into 1-inch cubes
  • 1 bell pepper cut into 1½-inch pieces
  • ½ large red onion sliced into wedges
  • 12 oz brussel sprouts halved lengthwise (can sub with zucchini slices but add it during the last 10 minutes of the bake time)
  • 1/3 cup finely grated parmesan cheese, divided

Marinade:

  • ¼ cup olive oil
  • 1 lemon juiced (about 3 tablespoons)
  • 4-6 garlic cloves minced
  • 1 tsp dried oregano
  • 1 tsp dried thyme
  • 1 tsp Dijon mustard
  • 2 tsp tomato paste
  • 2 tsp salt
  • ½ tsp freshly ground black pepper

Garnish:

  • 1 tbsp finely chopped fresh parsley
  • extra Parmesan cheese

Instructions

Preheat the Oven

  • Preheat the oven to 425°F.
  • In a large bowl, whisk together the olive oil, lemon juice, garlic, oregano, thyme, Dijon mustard, tomato paste, salt, and black pepper.
  • Reserve about ⅓ of the marinade for the vegetables.

Marinate the Chicken

  • Add the chicken thighs to the bowl with the remaining marinade and toss until well coated.
  • Let the chicken marinate for 10–15 minutes while you prepare the vegetables.

Season the Vegetables

  • Add the potatoes, bell pepper, red onion, and Brussels sprouts to a large sheet pan.
  • Drizzle with the reserved marinade and toss until evenly coated. Spread the vegetables into an even layer.
  • Optional: If you prefer your vegetables more highly seasoned, sprinkle with an additional ¼–½ teaspoon salt.

Assemble and Bake

  • Arrange the chicken thighs skin-side up over the vegetables.
  • Sprinkle with half of the Parmesan cheese and bake for 35–45 minutes, depending on the size of the chicken thighs, until:
    -The chicken reaches an internal temperature of 165°F
    -The potatoes are fork-tender
    -The vegetables are lightly browned
  • Boneless chicken thighs may cook more quickly, so begin checking for doneness around 30 minutes.

Broil for Extra Color

  • For crispier chicken skin and more golden vegetables, switch the oven to broil for 2–3 minutes, watching carefully to prevent the Parmesan from burning.

Finish and Serve

  • Remove from the oven and sprinkle with the remaining Parmesan cheese and fresh parsley before serving.
  • Serve warm with lemon wedges, crusty bread, or a simple salad.

Notes

  • Cut potatoes evenly: Aim for 1-inch pieces so they cook at the same rate as the chicken.
  • Use a large sheet pan: Overcrowding can cause the vegetables to steam instead of roast.
  • Add zucchini later: If using zucchini instead of Brussels sprouts, stir it in during the last 10 minutes to prevent it from becoming too soft.
  • For extra crispy skin: Pat the chicken dry before marinating and broil at the end.
  • Chicken thighs are forgiving: While chicken is safe at 165°F, thighs become even more tender around 175–185°F.
