French Onion Salisbury Steak Recipe

Add the 2 cups sliced onions and 1 teaspoon sugar to the same pan. Sauté for about 5 minutes, stirring occasionally, until the onions begin to soften and turn translucent.

Stir in 1 tablespoon minced garlic and 1 tablespoon tomato paste. Continue to sauté for another 1 minute, or until the tomato paste starts to brown slightly and smells fragrant.

Sprinkle the reserved 1 teaspoon flour over the onion mixture and cook, stirring, for 1 minute. Pour in the 2 cups beef broth and 1/4 cup wine, then stir in 3/4 teaspoon kosher salt and 1/2 teaspoon thyme. Bring the sauce to a boil, scraping up any browned bits from the bottom of the pan.

Return the seared meat patties to the pan. Reduce the heat to medium-low, cover the pan, and let the sauce simmer gently for 10 minutes, allowing the flavors to meld.
