01 - Preheat oven to 400°F. Pat the chicken drumsticks dry with paper towels.
02 - In a large bowl, combine sweet paprika, smoked paprika, garlic powder, onion powder, salt, and black pepper. Add the drumsticks and toss thoroughly until evenly coated on all sides.
03 - Heat olive oil in a large oven-safe skillet over medium-high heat. Sear the drumsticks, turning occasionally, until golden brown on all sides, approximately 6 to 8 minutes. Transfer the drumsticks to a plate and set aside.
04 - Reduce heat to medium. Add the chopped onion to the same skillet 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, scraping up any browned bits from the bottom of the skillet. Stir in the heavy cream and Dijon mustard, whisking gently until the sauce is smooth and well combined.
06 - Return the drumsticks to the skillet, turning to coat them evenly in the sauce. Transfer the uncovered skillet to the oven and bake for 25 minutes, or until the internal temperature of the thickest drumstick reaches 165°F.
07 - Remove from the oven and sprinkle generously with fresh parsley. Serve immediately while hot, accompanied by your choice of side dishes.
