Preheat your oven to 375°F (190°C) and line a small loaf pan or baking sheet with parchment paper.
In a large mixing bowl, combine the ground beef, egg, almond flour, finely diced onion, and grated carrots.
Add the garlic powder, onion powder, sea salt, black pepper, and dried parsley to the bowl.
Using your hands, gently mix the ingredients together until just combined, being careful not to over-compress the meat.
Form the mixture into a uniform loaf shape and place it onto the prepared baking surface.
In a small ramekin, whisk together the tomato paste and honey until smooth to create the glaze.
Spread the tomato glaze evenly over the top and sides of the meatloaf using a spoon or brush.
Bake for 35 to 40 minutes, or until the internal temperature reaches 160°F (71°C).
Remove from the oven and let the meatloaf rest for 5 to 10 minutes before slicing into thick portions.
