Step 1

In the bottom of a slow cooker, add beer, onion soup mix, chicken base, dried parsley, and 1 teaspoon white pepper. Add turkey breast. Cover and cook on LOW for 6 to 8 hours or HIGH for 3 to 4 hours.

Step 2

Remove turkey breast from slow cooker and transfer to a rimmed baking sheet. Take off skin and separate meat from bones, discarding bones and skin. Shred turkey.

Step 3

While the meat is still out of the slow cooker, stir in butter until melted. For a thicker broth, remove 1/2 cup broth and whisk with cornstarch. Add back to slow cooker.

Step 4

Add shredded turkey back to slow cooker and heat until broth is thickened, about 10 minutes. Season to taste with salt and white pepper. Serve with rolls.
