Laura’s Stuffed Burgers with Zinfandel Sauce

Ingredients

3/4 pound ground beef
1 (1 ounce) package dry onion soup mix
1 cup minced red onion
1 1/2 teaspoons Worcestershire sauce
2 teaspoons garlic, minced
1 tablespoon Dijon mustard
2 ounces fontina cheese, cubed
3/4 cup bacon bits
1 tablespoon olive oil
1 cup minced red onion
6 ounces button mushrooms, sliced
1 teaspoon minced garlic
1 (14 ounce) can low-sodium beef broth
1 cup full-bodied red wine, such as Zinfandel
1 (4 ounce) container crumbled Gorgonzola cheese
2 Kaiser rolls, split

Directions

Preheat an outdoor grill for medium-high heat, and lightly oil the grate.

Mix together the ground beef, onion soup mix, 1 cup minced red onion, Worcestershire sauce, garlic, and Dijon mustard with your hands. Shape the mixture into 4 patties of equal size. Place about half of the fontina cheese and bacon bits in the center of 2 of the patties; top with the other 2 patties and press edges of the patties to seal the cheese and bacon inside.

Heat the olive oil in a large skillet over medium-high heat. Cook 1 cup red onion in the hot oil until translucent, about 5 minutes. Add the mushrooms and garlic to the onions; cook and stir until the mushrooms are softened, about 5 minutes. Pour the beef broth and Zinfandel into the skillet and bring to a simmer; allow to cook until the liquid reduces by about half.

Cook burgers on the preheated grill to your desired degree of doneness, 7 to 10 minutes per side for well done. An instant-read thermometer inserted into the center should read 160 degrees F (70 degrees C). Top the burgers with equal amounts of the Gorgonzola cheese; cook until the Gorgonzola begins to melt, about 1 minute more. Place the burgers on the Kaiser rolls and top with the Zinfandel reduction sauce to serve.
