First, mix the ground beef with the seasonings and dice the onions. Then, form the patties or the hamburger steaks. The sizes can and will vary but don't make them so big they take forever to cook all the way through.
Prep the other ingredients for the onion gravy as well.
In a frying pan on medium high heat add a little oil the cook the hamburger steaks until fully cooked. Then, remove from the pan and set hamburger to the side.
Now, toss in the diced onion into the pan. Cook the onions until they start to brown a little. When the onions are almost done lower the heat to medium.
If the pan looks dry you can toss in a tablespoon or two of butter. Next, sprinkle the flour over the onions then mix around until things start to bubble a little.
Then, pour in the broth, milk and crumble the bouillon cube over the gravy. Mix everything up until well combined.
Lower the heat to medium low and add the patties back in. Baste the hamburger steak with the gravy and allow them to sit in the gravy carefully simmering for 5 minutes then turn the stove off.
Allow to cool a bit before serving and enjoy.
