Preheat the oven to 425°F.
Pat the chicken breast dry and season both sides with salt, pepper, and chopped fresh herbs.
Squeeze lemon juice over the chicken and let it marinate for 10 minutes while you prepare the rice and broccoli.
Place the chicken on a baking sheet lined with parchment paper. Optionally, drizzle a tiny bit of olive oil on top to enhance crisping.
Roast the chicken in the oven for about 20-25 minutes until the skin is crisp and the internal temperature reaches 165°F.
Meanwhile, in a small pot, reheat or prepare the brown rice according to package instructions to ensure it's fluffy.
Toss broccoli florets with olive oil, salt, and pepper. Spread them on another baking tray or in a roasting pan.
Roast the broccoli in the oven for 15 minutes, stirring halfway through, until tender with slight crispy edges.
Once all components are cooked, plate the sliced crispy lemon herb chicken alongside a serving of brown rice and roasted broccoli.
Drizzle any remaining pan juices over the chicken if desired, and serve immediately while warm.
