Preheat your oven to 400°F (200°C).
Season the chicken breast with half of the sea salt and black pepper, then place on a parchment-lined baking sheet and roast for 20-25 minutes until the internal temperature reaches 165°F.
While the chicken roasts, heat the olive oil in a small saucepan over medium heat.
Add the diced yellow onion and sauté for 3-4 minutes until translucent, then add the minced garlic and cook for another 30 seconds until fragrant.
Stir in the jasmine rice and toast the grains for 1 minute before pouring in the chicken broth and remaining salt and pepper.
Bring to a boil, then reduce heat to low, cover, and simmer for 15 minutes or until all liquid is absorbed.
Remove the rice from heat and let it sit covered for 5 minutes.
Fluff the rice with a fork and stir in the lemon juice, lemon zest, chopped parsley, and chopped dill.
Slice the roasted chicken breast and serve it immediately over the warm lemon-herb rice pilaf.
