Dice the chicken breast into bite-sized pieces and season evenly with the sea salt, black pepper, and smoked paprika.
Heat the avocado oil in a large skillet over medium-high heat until shimmering.
Add the chicken to the skillet and sear until golden brown on all sides, then remove the chicken and set it aside on a plate.
In the same skillet, add the diced yellow onion and red bell pepper, sautéing for 5 minutes until the vegetables have softened.
Stir in the minced garlic and the dry brown basmati rice, toasting the grains for 2 minutes until they become fragrant and slightly translucent.
Pour in the chicken bone broth, using a wooden spoon to scrape up any flavorful browned bits from the bottom of the pan.
Return the seared chicken and any accumulated juices to the skillet and bring the mixture to a boil.
Reduce the heat to low, cover the skillet with a tight-fitting lid, and simmer for 35 to 40 minutes until the rice is tender and the liquid is fully absorbed.
Remove the skillet from the heat and let it sit, covered, for 5 minutes to allow the rice to finish steaming.
Fluff the rice with a fork, garnish with chopped fresh parsley, and serve warm.
