01 - Preheat oven to 400°F. Pat chicken drumsticks dry with paper towels and set aside.
02 - In a large mixing bowl, combine sweet paprika, smoked paprika, garlic powder, onion powder, salt, and black pepper. Add the drumsticks and toss thoroughly until every piece is evenly coated with the spice mixture.
03 - Heat olive oil in a large oven-safe skillet over medium-high heat. Sear the drumsticks on all sides until deeply golden, approximately 6 to 8 minutes total. Remove the chicken and set it aside on a plate.
04 - In the same skillet, add the chopped onion and sauté for about 3 minutes until softened. Stir in the minced garlic and cook for 30 seconds until fragrant.
05 - Pour in the chicken broth, using a wooden spoon to scrape up any browned bits from the bottom of the pan. Stir in the heavy cream and Dijon mustard until the sauce is smooth and well combined.
06 - Return the drumsticks to the skillet, turning each piece to coat evenly in the sauce. Transfer the uncovered skillet to the oven and bake for 25 minutes, or until the chicken reaches an internal temperature of 165°F.
07 - Remove from the oven and sprinkle generously with fresh chopped parsley. Serve immediately while hot, pairing with your choice of side dishes.
