01 - Preheat oven to 400°F.
02 - Pat chicken thighs dry with paper towels. Season all sides evenly with salt, black pepper, smoked paprika, dried thyme, and dried basil.
03 - In a large oven-safe skillet, melt butter over medium-high heat. Place chicken thighs skin side down and sear for 3-4 minutes until golden brown. Flip and sear the opposite side for 2 minutes. Remove chicken and set aside.
04 - In the same skillet, add chopped onion and sauté for 2 minutes until softened. Add minced garlic and cook for 1 minute until fragrant.
05 - Pour in chicken broth, scraping up any browned bits from the bottom of the skillet. Stir in heavy cream and grated Parmesan cheese, stirring continuously until the sauce is smooth and slightly thickened.
06 - Place chicken thighs skin side up back into the skillet, nestling them into the sauce. Spoon some of the cream sauce over the top of each thigh.
07 - Transfer the skillet to the oven and bake uncovered for 25-30 minutes, until the chicken reaches an internal temperature of 165°F and the sauce is bubbly.
08 - Remove from the oven, garnish with fresh chopped parsley, and serve immediately.
