Season and sear the chicken: Heat olive oil in a large skillet over medium heat. Season chicken thighs with salt, pepper, and smoked paprika. Sear the chicken till golden brown, 4–5 minutes per side. Take out and put aside.
Sauté the aromatics: In the same skillet, add diced onion and sauté for 2-3 minutes until softened. Cook the minced garlic for 30 seconds until it becomes fragrant.
Cook the rice: Stir in the rice and toast for 1 minute. Pour in the chicken broth and ½ cup of BBQ sauce, stirring to combine.
Combine and simmer: Nestle the seared chicken back into the skillet. Cover and simmer on low heat for 20-25 minutes, until the rice is tender and the chicken is fully cooked (165°F internal temperature).
Add finishing touches: Stir in frozen peas or corn (if using) and the remaining ¼ cup BBQ sauce. Cook until thoroughly cooked, 2 to 3 minutes. Serve hot, garnished with parsley.
