In a small bowl, combine paprika, oregano, thyme, garlic powder, onion powder, salt, and pepper. Coat both sides of the chicken thighs evenly with the seasoning mix.
Heat 1 tablespoon oil in a deep skillet over medium heat. Add the chicken and cook for a few minutes per side until well browned. Remove to a plate.
Reduce heat to medium-low. Add remaining oil and sauté the diced onion for about 5 minutes until softened, scraping up browned bits from the pan.
Add the uncooked rice and sauté for 1–2 minutes to lightly toast.
Pour in the vegetable broth and stir briefly to deglaze the skillet.
Return the chicken to the skillet, placing it on top of the rice. Cover with a lid and bring to a boil over medium-high heat.
Once boiling, reduce heat to low and simmer for 20 minutes without lifting the lid.
Turn off heat and let rest for 5 minutes, still covered.
Remove lid, fluff the rice around the chicken, garnish with parsley if desired, and serve.
Notes
Add frozen peas or carrots in the last 5 minutes for extra vegetables
