Preheat your oven to 400°F (200°C) and line a small baking sheet with parchment paper.
Season the chicken breast evenly with sea salt, black pepper, and dried oregano on both sides.
Place the chicken on the baking sheet and roast for 20-25 minutes, or until the internal temperature reaches 165°F.
While the chicken is roasting, heat the olive oil in a small saucepan over medium heat and sauté the minced garlic for 1 minute until fragrant.
Add the dry basmati rice to the pan and toast for 1-2 minutes, stirring constantly to coat the grains in oil.
Pour in the chicken broth, bring to a boil, then reduce heat to low, cover, and simmer for 15 minutes or until liquid is absorbed.
Remove the rice from heat and let it sit covered for 5 minutes before fluffing with a fork.
Stir the fresh lemon juice, lemon zest, and chopped parsley into the rice pilaf.
Slice the roasted chicken breast and serve it over the warm, citrusy rice pilaf.
