01 - Preheat oven to 400°F. Position the rack in the center of the oven.
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 blend evenly over all sides of each chicken thigh.
03 - Melt butter in a large oven-safe skillet over medium-high heat. Place chicken thighs skin side down and sear for 3–4 minutes until the skin turns golden brown and crisp. Flip each piece and sear the opposite side for 2 minutes. Transfer the chicken to a plate and set aside.
04 - In the same skillet, add the chopped onion and sauté for 2 minutes until softened. Add the minced garlic and cook for an additional 1 minute 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 grated Parmesan cheese. Continue stirring until the sauce is smooth and begins to slightly thicken.
06 - Nestle the seared chicken thighs back into the skillet, skin side up. Spoon some of the cream sauce over the top of each thigh.
07 - Transfer the skillet to the preheated 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 freshly chopped parsley, and serve immediately while hot.
