Rinse the turkey inside and out and pat dry with paper towels.
Place turkey in crockpot with the breast side up. Tie its legs together with some kitchen twine. You might need to tuck the turkey wings down under the bird to get the lid on.
Combine melted butter, salt, pepper and paprika in a small bowl.
Drizzle butter mixture onto turkey.
Rub all over the bird to coat.
Place the lid on the slow cooker. Make sure it is on tightly. If it does not fit on tightly, cover with foil to prevent steam from leaking out.
Cook on low for 7-8 hours or on high for 3-4 hours.
Check the temperature of the turkey in the center of the turkey breast. The temperature should be at least 165° in the breast and 170° in the legs.
Turn oven to broil. Remove the turkey from the crock and place on a baking sheet. Broil for 10 minutes until skin begins to crisp.
Allow the turkey to rest for 10 minutes before carving.
