Preheat your oven to 400°F (200°C) and line a small baking sheet with parchment paper.
Pat the chicken breast dry with a paper towel to ensure a good roast.
In a small bowl, combine 0.25 tbsp of olive oil with the dried oregano, dried thyme, sea salt, black pepper, and lemon zest.
Rub the herb mixture evenly over the chicken breast and place it on the prepared baking sheet.
Roast the chicken for 20-25 minutes, or until the internal temperature reaches 165°F.
While the chicken is roasting, heat the remaining 0.25 tbsp of olive oil in a small saucepan over medium heat.
Add the finely diced yellow onion and minced garlic to the saucepan, sautéing until translucent and fragrant.
Add the basmati rice to the pan and stir for 1 minute to lightly toast the grains.
Pour in the chicken bone broth and bring the mixture to a boil.
Reduce the heat to low, cover the pan with a tight-fitting lid, and simmer for 15 minutes.
Remove the rice from the heat and let it sit, covered, for 5 minutes before fluffing with a fork.
Slice the roasted chicken breast and serve it over the rice pilaf, garnished with freshly chopped parsley.
