Preheat the oven to 375 degrees and lightly coat a 12-cup muffin tin with cooking spray.
In a large bowl, combine the ground turkey, breadcrumbs, egg, onion, garlic, 3 tablespoons of the cranberry sauce, Worcestershire sauce, thyme, salt, and pepper. Mix gently with your hands until the ingredients are evenly distributed.
Divide the mixture evenly among 8 muffin cups, pressing it down lightly to fill each one.
Spoon the remaining cranberry sauce over the top of each muffin, spreading it into a thin layer.
Bake for 25 minutes until the internal temperature reaches 165 degrees and the tops look set.
Let the muffins rest in the tin for 5 minutes before removing them to serve.
