Preheat the oven to 375 degrees F. Line a baking sheet with parchment paper. Place a wire rack on top of the parchment paper if you have one. In a large bowl, add the milk to the oats and allow it to soak for 5 minutes.
Next, add the ground beef, shredded carrot, shredded onion, ketchup, mustard, salt and pepper. Mix until combined.
Divide the meat mixture into 8 equal sections.
Form the mixture into 8 round loaves and flatten each loaf slightly. Place loaves on a baking sheet and bake for 25 minutes.
While the loaves are baking, combine the ketchup, coconut sugar, worcestershire sauce and mustard in a small bowl.
Take the meatloaves out of the oven and spoon about a tablespoon of sauce over each loaf. Bake for 5-7 additional minutes. Allow the meatloaf to sit for 10 minutes.
Garnish the finished meatloaves with freshly chopped parsley, if desired. Serve immediately.
