In an oven safe pan, over medium heat, add the butter and melt.
Add the diced onion and allow to sautee.
While the onion is cooking, in a large bowl, add the ground meat, breadcrumbs, salt, garlic powder, onion powder, parsley and soy sauce.
Mix until well combined, and form into meatballs.
Add to the saucepan with the onions.
Bake in a preheated 400℉ oven for about 22 minutes, or until the internal temperature of the meatballs reaches 160°.
Place the meatballs on a separate plate.
To the pan add the beef bouillon, beef broth and all-purpose flour.
Whisk until the flour is nicely combined without any clumps remaining.
Add the half and half and stir. Add the meatballs back in and it is ready to serve!
