Salisbury Steak Burgers - cooking recipe

Ingredients

1 lb ground sirloin
1/2 cup plain breadcrumbs
1 medium onion, finely chopped
2 garlic cloves, minced
1 large egg
1 teaspoon salt
1/2 teaspoon fresh coarse ground black pepper
1 tablespoon canola oil
3 tablespoons cornstarch
2 cups beef broth
8 ounces white mushrooms, sliced
1/4 cup ketchup
2 tablespoons Worcestershire sauce
1/2 teaspoon dry mustard
4 hamburger buns

Preparation

In a bowl, gently mix together the beef, bread crumbs, half of the onion, garlic, egg, salt, and pepper; form into 4 patties, each 3/4 inch thick.
Heat the oil in a large skillet over med-high heat; cook the burgers until just cooked through, about 3-5 minutes per side.
Remove patties from the pan and set aside; reserve pan drippings.
In a bowl, mix the cornstarch with 1 cup broth.
To the reserved drippings, add the remaining onion and mushrooms; cook, stirring over med-high heat for about 2 minutes or until just softened, scraping the browned bits off the bottom of the pan.
Add in the remaining 1 cup broth, ketchup, Worcestershire sauce, and mustard; whisk in the broth/cornstarch mixture and bring to a boil for 1 minute; decrease heat to low, return burgers to the pan, and simmer for 3-5 minutes.
Serve on hamburger buns; top off with some of the pan juices.
