# Step-by-Step Guide:
01 - Set oven to 325°F (165°C).
02 - Pat chicken thighs dry and season evenly with salt and black pepper.
03 - Heat butter or olive oil in a large, oven-safe pot over medium-high heat. Brown chicken thighs on both sides, 3–4 minutes per side. Remove and set aside.
04 - Reduce heat to medium. Add sliced onion, carrots, and celery to the pot and cook until softened, about 4–5 minutes. Stir in minced garlic and cook 1 minute more.
05 - Return chicken to the pot. Distribute drained pickled onions around and atop the chicken.
06 - Whisk together reserved onion brine, chicken broth, brown sugar, Dijon mustard, Worcestershire sauce, thyme, and oregano. Pour evenly over chicken and vegetables.
07 - Cover pot and transfer to oven. Braise for 2.5 to 3 hours until chicken is tender.
08 - Taste sauce and adjust seasoning if needed. Sprinkle with fresh parsley before serving.
