Set the oven to 400°F.
Prep all ingredients. See quantities in the recipe card.
Place ground turkey in a large bowl and break it apart with a fork or other utensil.
Add breadcrumbs and mix into ground turkey.
Pour whisked egg over the turkey and mix.
Add diced onion. I suggest either using a food processor or simply making sure that you dice it well. Mine were a little big but didn’t affect how I felt about the consistency!
Next, add coconut aminos. You may also choose soy sauce or worcestershire. See comments above about quality ingredients.
Add milk. This can be dairy free milk or an organic dairy source.
Next, add seasonings. You might choose to add all seasonings to one bowl and add altogether to the mixture. Add parsley, salt, pepper, garlic powder. Stir.
For the glaze, add ketchup, maple syrup, and vinegar to a bowl.
Whisk together.
Spread meatloaf mixture evenly into a greased 9x13 loaf pan.
Top with glaze.
Bake for at least 50 minutes at 400°F, or until the loaf reaches an internal temperature of at least 165°F.
Let cool for 10 minutes before slicing. The loaf will shrink away from the sides of the loaf pan. This will make it easy to remove.
