01 - Preheat oven to 400°F. Position the rack in the center.
02 - Pat the chicken thighs dry with paper towels. Combine salt, pepper, smoked paprika, dried thyme, and dried basil in a small bowl. Rub the seasoning mixture evenly over all surfaces of each thigh.
03 - Melt butter in a large oven-safe skillet over medium-high heat. Place chicken thighs skin-side down and sear for 3 to 4 minutes until deeply golden. Flip and cook the opposite side for 2 minutes. Transfer the thighs to a plate and set aside.
04 - In the same skillet, sauté the chopped onion for 2 minutes until softened. Add the minced garlic and stir for 1 minute until fragrant. Pour in the chicken broth, scraping up any browned bits from the bottom of the pan. Stir in the heavy cream and Parmesan cheese, continuing to stir until the sauce is smooth and slightly thickened.
05 - Nestle the seared chicken thighs back into the skillet, skin-side up. Spoon some of the cream sauce over the top of each thigh. Transfer the skillet to the oven and bake uncovered for 25 to 30 minutes, until the chicken reaches an internal temperature of 165°F and the sauce is bubbly.
06 - Remove from the oven, sprinkle with fresh chopped parsley, and serve immediately while hot.
