Caramelized Onion Burgers

These caramelized onion burgers are elevated to gourmet status. Taking the time to properly caramelize the onions with beef broth and balsamic vinegar creates this sweet, complex topping that transforms an ordinary burger into something extraordinary. The ground chuck seasoned with grated onion and French onion soup mix stays juicy and flavorful, while the Gruyere adds that perfect creamy, nutty element. A burger that's restaurant-worthy but totally doable at home. 

Ingredients:

For the onions:

1 T olive oil

1 large yellow onion

1/4 cup beef broth

3 T sugar

1T balsamic vinegar

S&P

For the burgers:

1.5 lbs ground chuck (85/15)

2 T grated onion

1 T dry French onion soup mix

1 cup shredded Gruyere cheese

4 brioche or potato buns, toasted

Arugula

 

Directions:

For the onions: Heat oil in a large skillet over medium-high heat. Add the onions and sauté till brown, 4 to 5 minutes. Add the broth and sugar. Reduce heat to low and cook until the onions are caramelized, about 20 minutes. The onions will reduce significantly.  Stir in vinegar and season with S&P. Remove from the heat.

For the burgers: place beef, onion and soup mix in a large bowl. Mix to combine. Shape into 4 patties.

Fry burgers on the grill or in a skillet. When almost done, top burgers with the Gruyere cheese and cover to melt.

Serve on toasted buns with the caramelized onions and arugula.
