Divide the burgers into 8 2-inch balls, then flatten them into patties.

Olive oil 1 tablespoon
Fry your burger patties until golden brown, about 3-4 minutes per side. Transfer the cooked patties to a plate or platter, cover with a square of aluminum foil and set aside. *Drain the fat if necessary before sautéing the onions and mushrooms.
Mushroom and onion sauce
Add sliced mushrooms and onions to your skillet and sauté until tender, about 4 minutes. Add the garlic and sauté for another 30 seconds then deglaze your pan with the cooking sherry wine.
1 cup white onion, 1 cup white mushrooms, 2 tbsp dry sherry, 1 tbsp garlic
Let the sherry simmer while you scrape the bottom of the pan to make sure all the fried bits are loosened, then add your beef broth and stir to combine. Whisk cornstarch slurry until well blended.
2 cups beef broth, 1 tbsp cornstarch
Bring the sauce to a boil then reduce the heat. Continue to simmer for 5 minutes, then place the browned burgers in the sauce and simmer over low heat. Cover and let the burgers cook in the sauce for 10 to 15 minutes before serving.
