Sear the ground beef in a large skillet, seasoning with the black pepper. Use a silicone spatula to crumble the meat as you're cooking.
Drain any excess grease (if using a fattier beef), then add in the ginger paste and minced garlic.
Cook for another two minutes or until aromatic.
Pour in the brown sugar, coconut aminos, sesame oil, cornstarch, and hot water.
Stir well until combined and a thick sauce begins to form on the beef.
If you're serving with cabbage, push the meat to one side of the skillet and add the shredded cabbage to the other side.
Sauté for a few minutes until softened, stirring occasionally, then season with salt.
Finally, remove the pan from heat and top the Korean Beef with chopped green onions and sesame seeds.
Spoon over cooked white rice. Serve with extra green onions, sesame seeds, and (optional) red pepper flakes for a hint of spice. Enjoy!
