Completely thaw turkey.
Rinse and soak turkey in cold water for 30 minutes to remove any ice crystals.
Dry turkey off with paper towels. Set aside.
To a small pot over medium heat add butter, chicken stock, chicken base, salt, garlic powder, onion powder and paprika. Bring to a low boil and whisk until everything comes together and the salt dissolves.
Remove marinade from the heat and allow to cool for 30 minutes.
Inject marinade 1 tablespoon at a time into the turkey. Focus on the breast. Create 10 injection sites in each breast. Inject remaining marinade into the legs.
Massage the marinade into the turkey.
Add a high smoke point oil like canola or peanut oil to the turkey fryer just below the max fill line.
Set electric fryer to 375 degrees. It will take about 45 minutes to preheat.
Dry turkey off with paper towels, place in the basket and SLOWLY lower into the oil with the hooks provided.
Once fully submerged, close the lid and lower temperature to 325 degrees.
Set a time for 3 1/2 minutes per pound of turkey.
Remove basket from oil using hooks provided. Hang on the ledge and take the temperature 2 inches into the thickest part of the breast. If the internal temperature hasn't reached 160 degrees, put back in the oil for 5 minute increments and take the temperature until you reach 160 degrees.
Allow the turkey to rest for 10 minutes before carving.
