Step 1

Combine breadcrumbs, grated onion, and beef broth in a bowl and set aside.

Step 2

In a large bowl, add ground beef, soaked breadcrumbs, dijon mustard, Worcestershire sauce, salt, black pepper, and garlic powder to the large bowl. Mix with hands until incorporated and then form into patties.

Step 3

Heat oil in a 12-inch skillet over medium-high heat. Add patties and brown on each side, for about 3 minutes per side. Remove patties from the skillet and set aside.

Step 4

Reduce heat to medium and add butter to the pan. Once butter has melted, add yellow onion to the skillet and saute for about 3 minutes, until softened. Add garlic and cook for a minute more. Add mushrooms and cook for an additional 5 minutes, until mushrooms have softened. Sprinkle it with flour and stir for 1-2 minutes. Whisk in beef broth.

Step 5

Return patties to gravy and allow to cook in gravy for 8-10 minutes, until cooked through and gravy has thickened a little. Serve and enjoy.
