# How to make it:
01 - Preheat the oven to 325°F (165°C).
02 - Pat chicken thighs dry with paper towels and season evenly with kosher salt and black pepper.
03 - In a large Dutch oven over medium-high heat, melt butter or heat olive oil. Sear chicken thighs in batches until golden brown on both sides, approximately 3 to 4 minutes per side. Remove and set aside.
04 - Reduce heat to medium. Add sliced onion, carrots, and celery to the pot. Sauté for 4 to 5 minutes until softened. Stir in minced garlic and cook for an additional minute.
05 - Return chicken thighs to the pot. Distribute drained pickled onions over and around the chicken.
06 - In a small bowl, whisk together reserved onion brine, chicken broth, brown sugar, Dijon mustard, Worcestershire sauce, dried thyme, and dried oregano. Pour the mixture evenly over the chicken and vegetables.
07 - Cover the pot tightly with a lid and transfer to the preheated oven. Braise for 2.5 to 3 hours until the chicken is tender.
08 - Carefully taste the sauce and adjust seasoning if necessary. Sprinkle fresh chopped parsley on top before serving.
