Preheat your oven to 400°F (200°C).
Season the chicken breast evenly with sea salt, black pepper, and dried oregano.
Place the chicken on a parchment-lined baking sheet and roast for 20-25 minutes until the internal temperature reaches 165°F.
While the chicken roasts, heat olive oil in a small saucepan over medium heat and sauté the minced garlic for 1 minute until fragrant.
Add the basmati rice to the pan and stir for 1 minute to lightly toast the grains.
Pour in the chicken broth, bring to a boil, then reduce heat to low and cover with a tight-fitting lid.
Simmer the rice for 15 minutes, then remove from heat and let sit covered for 5 minutes.
Fluff the rice with a fork and stir in the lemon juice, lemon zest, and chopped fresh parsley.
Slice the roasted chicken and serve it immediately over the warm lemon-herb pilaf.
