Line your slow cooker with a liner or spray with non-stick cooking spray.
Place the onion, garlic, carrots, chicken broth, and sprigs of herbs in the bottom of the slow cooker.
Combine the softened butter, garlic powder, dried onion flakes, salt, paprika, sage, rosemary, thyme, and pepper in a bowl. Stir to incorporate the herbs into the butter.
Spread the butter mixture generously all over the thawed turkey.
Place the turkey into the crockpot and cook on LOW for 6 hours or HIGH for 4 hours. The turkey is done when the temperature reads 165 degrees Fahrenheit with a thermometer.
Carefully remove your turkey from the slow cooker and place it on a platter. Let it rest for 5 minutes before slicing and enjoy!
