01 - Preheat oven to 400°F. Pat chicken drumsticks dry with paper towels.
02 - In a large bowl, combine sweet paprika, smoked paprika, garlic powder, onion powder, salt, and black pepper. Toss the drumsticks in the spice mixture until evenly coated on all sides.
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 and set aside on a plate.
04 - In the same skillet, sauté the chopped onion over medium heat for 3 minutes until softened. Add minced garlic and cook for 30 seconds until fragrant.
05 - Pour in chicken broth, scraping up any browned bits from the bottom of the pan. Stir in heavy cream and Dijon mustard until fully incorporated and smooth.
06 - Return the drumsticks to the skillet, turning to coat thoroughly 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 oven and garnish with freshly chopped parsley. Serve hot alongside your choice of side dishes.
