2 cups thinly sliced shallots (about 2-3 large shallots)
2 ounces sharp cheddar cheese, shredded (about ½ cup)
1 cup baby arugula
4 hamburger buns, toasted (I used onion buns from a local bakery)
Ketchup (optional, for topping)
Mayonnaise (optional, for topping)
Instructions
Prepare burger: Using a silicone spatula, gently combine beef and garlic. (Be careful not to over-handle meat).
Divide beef into 4 equal portions, shaping into a ½" think patty. Press a small indentation in the center of each burger. Sprinkle evenly with ¼ teaspoon salt. Refrigerate until ready to cook.
Caramelize shallots: Meanwhile, heat 2 teaspoons oil in a nonstick skillet over medium-low heat. Add shallots and ¼ teaspoon salt; cook 15-20 minutes or until golden brown, stirring occasionally. Stir in vinegar, cook for an additional minute and the remove from heat. Keep warm.
Grill burger: Preheat grill to medium-high heat. If needed, spray grate with grilling cooking spray or rub with oil. Cook for approximately 3 minutes per side, or to desired doneness. Top each burger with 2 tablespoons cheese and cook for 1 minute, or until cheese melts.
Assemble: Place ¼ cup arugula on bottom half of bun; top 1 burger and ¼ of the shallots. If desired, spread ketchup or mayonnaise (or desired topping) on top half of buns, and place on top of burgers. Enjoy!
