Step 1

Fire up the grill for a mid-high heat. While the grill is heating up make the balsamic glaze per the instructions (click on link above in ingredients list for homemade balsamic glaze). This will take about 15 to 20 minutes. When the glaze is ready it should coat the back of a spoon and taste deliciously sweet and tangy. Set aside until ready to use.

Step 2

While the glaze is simmering, in a bowl combine 1 lb ground chuck, 1/3 cup mushrooms, 1/2 tablespoon garlic, 1/4 cup minced onion, 1 tablespoon chopped parsley, 1/4 cup almond flour, 1 egg, 1 teaspoon kosher salt, and a 1/2 teaspoon pepper. Mix everything until well combined and form into 4 hamburger patties.

Step 3

When the grill is ready, place the patties over mid-high heat and cook, undisturbed for about 5 minutes until the patties have a nice sear on one side. Flip the burgers and cook about 5 minutes again until the 2nd side forms a nice crispy sear. During the last minute or so of cooking I baste each burger with the balsamic glaze and top with a slice of mozzarella cheese. Continue to cook until the cheese melts and the burgers are cooked through. Keep in mind the cook time will vary depending on how thick or thin you formed the patties, so adjust the times as needed. Cook until the juices run clear.

Step 4

To assemble the burgers, top each bun with a cheeseburger patty and add fresh basil leaves, sliced tomatoes and another drizzle of balsamic dressing. Enjoy!
