Mix: Gather and chop all of your ingredients. Combine all ingredients in a large bowl and mix with clean hands or a large spoon until everything is combined. Be careful to not over mix, mix just enough to combine the ingredients.
Form: Using your hands form the turkey burgers into burger shapes on a sided baking pan. The mixture will be a gloopy consistency but do your best to form patty shapes on the pan. To avoid sticking you may want to use parchment paper, a non-stick reusable baking mat or a little oil on your pan.
Bake: Bake for approximately 30 minutes at 400° F. Using a meat thermometer ensure the middle of your burger is 165-180° F. If the internal temperature is lower than 165° F keep cooking them until the temperature is reached. Once cooked, let the burgers sit for 10 minutes before serving so the juices disperse throughout the burger.
Notes
Red onion substitution: same amount of shallot, white onion, yellow onion or green onion
Worcestershire sauce substitution: olive brine (juice from a jar of olives)
Parsley substitution: you can omit the parsley with minimal impact to the flavor
Storage: up to 3 days in an air tight container in the fridge. Up to 3 months in the freezer in an air tight container. Reheat by placing your frozen burger in a 400°F oven for 5 minutes or until fully warm.
