01 - Preheat your oven to 375°F.
02 - Pat the chicken thighs thoroughly dry with paper towels. Season generously on all sides with the salt, pepper, and paprika.
03 - Heat a large oven-safe skillet or Dutch oven over medium-high heat. Place the chicken thighs in the pan skin side down. Sear for 3 to 4 minutes until the skin is golden brown and crispy. Flip and cook for another 2 minutes. Remove the chicken from the pan and set aside on a plate.
04 - In the same pan, add the sliced onion, red bell pepper, green bell pepper, and minced garlic. Sauté for 3 to 4 minutes, stirring occasionally, until the vegetables are softened and fragrant.
05 - In a mixing bowl, whisk together the Catalina dressing, chicken broth, ketchup, brown sugar, and Worcestershire sauce until well combined.
06 - Return the seared chicken thighs to the pan, arranging them skin side up over the bed of vegetables. Pour the sauce mixture evenly over the chicken and vegetables.
07 - Cover the pan with a tight-fitting lid or aluminum foil. Transfer to the preheated oven and braise for 25 minutes.
08 - Remove the lid or foil and continue cooking for an additional 10 minutes. This allows the sauce to thicken slightly and the chicken skin to brown further.
09 - Remove from the oven and let the chicken rest for 5 minutes before serving. This allows the juices to redistribute. Garnish with chopped fresh parsley if desired. Serve hot.
