Step 1

In a medium sized bowl, mix together the ground beef with ½ teaspoon of garlic powder, and salt and pepper to taste.

Step 2

Roughly divide the beef mixture into 4 or 5 balls, and then shape them into discs using your hands.

Step 3

Heat up the oil in a large frying pan, and then add the hamburger steaks. Fry for 3 minutes on each side, until nicely browned. Remove the steak from the pan, and set aside.

Step 4

Add the butter to the pan, along with the onion, and cook for 2 minutes. Then, add the mushrooms, and the remaining ½ teaspoon of garlic powder. Allow everything to soften for 5 minutes, stirring frequently.

Step 5

Mix in the flour, allowing it to fully absorb, before adding the beef stock to the pan.

Step 6

Allow everything to come to a simmer, stirring frequently, and then return the hamburger steaks to the pan. Simmer gently for 15 minutes, stirring occasionally. Check that the core temperature of the hamburger steaks is at least 160 F before serving.
