Tips and tricks for this slow cooker turkey breast recipe: 

Type of turkey breast:

You can use either boneless turkey breasts or bone-in turkey breasts for this recipe. Just be sure to note that the bone-in breast will take longer to cook through to the safe-to-eat temperature.

What temperature does the turkey need to be cooked to:

To be sure the turkey is cooked well, use a meat thermometer and cook the crock pot turkey until it has reached at least 165 degrees F to be safe to eat. 

Type of potatoes to use:

I enjoy using russet potatoes or Yukon gold potatoes in this recipe. They will make for creamy potatoes and delicious flavor.
