Romesco & Mozzarella Lamb Burger with potato chips


Romesco sauce 

  • 1 (12-ounce) jar of roasted red peppers, (drained), or fresh blistered red bell peppers, (skin and seeds removed) 
  • 1/2 cup walnuts 
  • 1/4 cup toasted breadcrumbs 
  • 1/2 cup sun-dried tomatoes packed in olive oil 
  • 1/2 cup shredded Parmesan cheese
  • 1-2 small, fresh garlic cloves 
  • 1 teaspoon paprika or Aleppo pepper
  • Juice of a lemon
  • 1/4 cup olive oil 
  • Salt and pepper to taste 

Burger fixings 

  • 1 pound ground American lamb 
  • 1 teaspoon olive oil 
  • Salt and pepper to taste
  • 6 ounces Mozzarella cheese 
  • 1 cup fresh basil leaves 
  • 4 store-bought brioche buns 
  • 1/4 cup aged balsamic vinegar 


To make the Romesco sauce, add all ingredients to the work bowl of your food processor. Pulse until you’ve reached a smooth consistency. Keeps in the fridge for up to 1 week. 

To make the burgers, form the meat into 4 patties. Smash the patties into round burgers using your hands, about 4-5 inches across. These will be thin but shrink up nicely to fit the bun. Grill these up at 350 degrees F on your outdoor grill, roughly 3-4 minutes per side (or fry in a skillet over medium-high heat). Season with salt and pepper to taste. If you prefer the burgers medium, simply cook for less time on the flip*. Add sliced mozzarella to each of the patties and allow to melt slightly in the pan. 

* Note: USDA recommends ground lamb reach an internal temperature of 160F.

To assemble the burgers, place a couple basil leaves on the bottom bun, place the cheesy patties on the basil, and top with 2 heaping tablespoons of romesco sauce and a twirl of balsamic vinegar. Top with the top bun and enjoy!
