01 - Place the chicken thighs in the bottom of the slow cooker, ensuring they lie flat for even cooking.
02 - Sprinkle the finely chopped onion and minced garlic evenly over the chicken pieces.
03 - In a mixing bowl, combine chicken broth, heavy cream, butter, Italian seasoning, paprika, salt, and pepper. Whisk until completely smooth and incorporated.
04 - Pour the creamy mixture evenly over the chicken thighs, ensuring all pieces are coated.
05 - Cover and cook on LOW setting for 6 hours or until the chicken reaches an internal temperature of 165°F and is fork-tender.
06 - About 15 minutes before serving, whisk cornstarch and cold water in a small bowl until smooth to create a slurry.
07 - Stir the slurry into the slow cooker, mixing well to incorporate. Cook uncovered for an additional 10–15 minutes until the gravy reaches desired thickness.
08 - Serve the chicken thighs topped with the creamy gravy alongside mashed potatoes, rice, or steamed vegetables.
