Let’s start summer off right with the ultimate flavor combination of caramelized onion and shaved beef burgers! Caramelized onion and shaved beef make a delicious pair in this succulent burger treat. This dish will have your friends and family asking for more!

To begin, let’s caramelize the onions. This process is both simple and delicious, and adds depth of flavor to the burgers. Heat a skillet on medium-high then add 2 tablespoons of butter. Cut two large onions into thin slices, add them to the buttered skillet, stir, and reduce the heat to medium. Slowly cook the onions, stirring occasionally. As they start to brown, add a pinch of salt and two tablespoons of brown sugar. Continue stirring and slowly caramelize the onions, until they are golden brown and tender. This can take 15-20 minutes, so allow plenty of time. Once the onions are finished, set them aside while you prepare the beef.

Next, use a beef tenderloin filet, which is extra-tender and perfect for burgers. With a sharp chef’s knife, trim any fat away and then slice the beef into about ¼ inch strips. Place the strips on a cutting board, season with salt and pepper, and run the knife over them so that the beef becomes shredded – just like shaved roast beef.

Now it’s time to assemble the burgers. Take a handful of beef and thinly spread it over the grill or skillet. Flip the burger over the heat, and repeat with remaining beef. Assemble the sandwiches, topping each patty with half the caramelized onions and your favorite hamburger buns. Place the assembled burgers on the grill or skillet and cook for 5 to 7 minutes on both sides, until the beef is cooked through and the buns are toasted.

To top off this amazing burger, it’s time for condiments! Top each sandwich with a thin slice of real cheddar, a good smear of mayonnaise, a spoonful of mustard, and a few more pickles.

These caramelized onion and shaved beef burgers are the perfect way to kick off the summer. Serve them up with your choice of sides, like potato chips, and beyond-a-doubt, everybody at the barbecue is sure to love this flavor sensation. Enjoy!
