Step 1

Combine the ground beef, eggs, potato chips, dry mustard, garlic powder, and some salt and pepper.

Step 2

Using your hands, mix all the ingredients until fully combined. Form into four hamburger patties.

Step 3

In a 12-inch skillet with the butter and oil over medium-high heat, fry the patties on both sides until no longer pink in the middle. (about 5 minutes a side)

Step 4

Remove patties from the skillet and pour off any excess grease.

Step 5

Reduce the heat to medium and add in the sliced onions. Stir and cook until golden brown and somewhat soft, about 3-5 minutes.

Step 6

In a small bowl, combine the beef broth and the corn starch. Mix well.

Step 7

Add the beef broth mixture and Worcestershire sauce to the onions and stir as the mixture comes to a low boil. The sauce will reduce and thicken.

Step 8

If the sauce appears too thick, you can add more broth for thinning.

Step 9

Return the cooked hamburger patties to the gravy. Spoon the gravy over the top and let them simmer and heat back up for a couple of minutes.
