Preheat the oven to 350° and line a cookie sheet or roasting pan with a piece of parchment paper.
This is an optional step: Place diced onion and a little coconut oil in a pan and sauté until softened and translucent. About 5-7min.
In a large bowl, mix beef, onion, sweet potato, almond flour, coconut flour, egg, ketchup, coconut aminos, salt, and garlic powder together. I find the best way to do this is with my hands. Mix until just combined- don't overtax or it can become tough.
Form into a loaf shape and place in pan.
Mix glaze ingredients in a small bowl and scoop on top of meatloaf.
Bake for 60 minutes and remove from oven. Carefully scoop out all grease into a jar or bowl.
Place back in oven for 30 min or until a thermometer reads 160°-165°.
