Preheat oven to 400°F. Season chicken thighs with paprika, salt, and pepper. Melt 2 tbsp butter in a large oven proof skillet over medium high heat. Add chicken skin side down and sear on both sides until golden brown. Set chicken aside and drain excess fat.
Melt 1 tbsp butter in skillet. Add garlic, stir until fragrant. Stir together chicken broth, heavy cream, parmesan, lemon juice, and thyme. Bring to boil then reduce to low heat.
Add spinach and stir until slightly wilted and sauce has thickened. Return chicken to skillet and bake at 400°F for 25 minutes, until chicken is cooked through. Enjoy!
