These easy homemade turkey burgers have become one of our favorite things to make. Lean ground turkey can be a bit bland, so we add lots of umami and flavor by stirring cooked chopped mushrooms into the burger mixture. The magic of the mushrooms doesn’t stop there. They also help keep the turkey burgers juicy and moist. If you are not a mushroom fan, don’t worry you don’t really taste them. Instead, they make the burger taste more meaty.
