Pat chicken thighs dry and season both sides with salt and pepper.
Heat olive oil in a large deep skillet or Dutch oven over medium-high heat.
Place chicken skin-side down and sear for 6-8 minutes until skin is crisp and golden; flip and sear for 3 more minutes before removing chicken from the pan and setting aside.
Reduce heat to medium, add diced onion to the remaining fat, and sauté for 5 minutes until translucent.
Add minced garlic and tomato paste, stirring constantly for 2 minutes to caramelize the paste.
Add the bulgur, cumin, and paprika to the pan, stirring for 1 minute to toast the grains.
Pour in the chicken stock and bring the mixture to a gentle boil, scraping the bottom of the pan to release browned bits.
Nestle the chicken thighs back into the bulgur mixture, skin-side up.
Cover with a tight-fitting lid, reduce heat to low, and simmer for 20-25 minutes until the liquid is absorbed and chicken is cooked through.
Remove from heat and let rest covered for 5 minutes; fluff the bulgur with a fork and garnish with chopped parsley before serving.
