01 - Preheat oven to 400°F. Position rack in the center of the oven.
02 - Pat the chicken drumsticks thoroughly dry with paper towels. In a large mixing bowl, combine sweet paprika, smoked paprika, garlic powder, onion powder, salt, and black pepper. Add the drumsticks and toss until evenly coated on all sides.
03 - Heat olive oil in a large oven-safe skillet over medium-high heat. Arrange the drumsticks in the skillet and brown on all sides, approximately 6 to 8 minutes total. Transfer the drumsticks to a plate and set aside.
04 - In the same skillet, add the finely chopped onion and sauté over medium heat for about 3 minutes until softened. Add the minced garlic and cook for 30 seconds until fragrant.
05 - Pour in the chicken broth, scraping up any browned bits from the bottom of the pan. Stir in the heavy cream and Dijon mustard, whisking until the sauce is smooth and fully 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 garnish with fresh chopped parsley. Serve immediately with your choice of side dishes.
