For the burgers: 

● 1 pound Ground American Lamb 

● 1 teaspoon kosher salt 

● ½ teaspoon freshly ground black pepper 

● 4 slices of your favorite cheese (such as feta or cheddar)

● 4 hamburger buns, split and toasted 


For the red onion jam: 

● 2 tablespoons olive oil 

● 2 red onions, thinly sliced 

● ¾ teaspoon kosher salt 

● ¼ cup balsamic vinegar 

● 1 tablespoon honey 


For the mustard mayo 

● ⅓ cup mayonnaise 

● 2 tablespoons whole grain mustard


1. Prepare red onion jam: 

Heat olive oil in a skillet over medium heat. 

Add the thinly sliced red onions and salt to the skillet and cook, stirring occasionally, until they become soft and caramelized, about 15 to 20 minutes. 

Once the onions are caramelized, add balsamic vinegar and honey to the skillet. Stir to combine. 

Continue cooking for another 2-3 minutes, or until the mixture has thickened into a jam-like consistency. 

Remove the skillet from heat and let the red onion jam cool slightly before using. 

2. Season the lamb: 

Season the American Lamb with kosher salt and black pepper. Divide the ground lamb into 4 equal portions and form each portion into a ball. Heat a large skillet or griddle over medium-high heat. 

3. Cook the Lamb Smashburgers: 

Place a ball of lamb onto the hot skillet and immediately press down firmly with a spatula to smash it into a patty. Repeat with the remaining lamb balls. 

Cook the patties for about 3 minutes per side, or until they develop a nice dark crust and are cooked to your desired level of doneness*. 

During the last minute of cooking, top each patty with a slice of cheese and allow it to melt. 

3. Prepare the mustard mayo: 

Stir together the mustard and mayo in a small bowl. 

4. Serving: 

Grill the buns in a pan with olive oil till crisp. 

To assemble the burgers, spread mustard mayo on the bottom bun. Place a lamb patty on top and spread a generous amount of red onion jam. Top with top bun and serve!
