Season the chicken breast evenly with the sea salt, black pepper, and dried oregano.
Heat the extra virgin olive oil in a skillet over medium-high heat and sear the chicken for 5-6 minutes per side until golden and the internal temperature reaches 165°F.
Remove the chicken from the skillet and let it rest on a cutting board while you prepare the pilaf.
In the same skillet, add the minced onion and garlic, sautéing for 2 minutes until fragrant and translucent.
Add the dry basmati rice to the skillet and toast for 1 minute, stirring constantly to coat the grains in the remaining pan juices.
Pour in the chicken broth, bring to a boil, then reduce the heat to low, cover, and simmer for 15 minutes.
Remove the rice from the heat and let it sit covered for 5 minutes before fluffing with a fork.
Stir in the lemon zest, fresh lemon juice, and chopped parsley to brighten the flavors.
Slice the rested chicken breast into strips and serve immediately over the warm lemon-herb rice pilaf.
