Beef Sliders with Caramelized Onions & Blue Cheese on Pretzel Buns

2 pounds ground beef

salt and pepper, to taste

nonstick cooking spray, for cooking the burgers

For the sliders:

pretzel slider buns

½ cup of your favorite mayonnaise

2 tablespoons prepared horseradish

caramelized onions (recipe below)

blue cheese, crumbled

1 bunch watercress, hard stems removed and discarded

olive oil, for drizzling

balsamic vinegar, for drizzling

For the caramelized onions:

2 tablespoons butter

2 tablespoons olive oil

2 large yellow onions, cut into thin strips (julienned)

pinch granulated sugar

kosher salt, to taste

Form the beef into ½-inch patties that are slightly larger than your slider buns (our patties were about 3 ounces each. Season the patties well with salt and pepper. Sear or grill the burgers until your desired doneness.

While the burgers cook, mix together the mayonnaise and horseradish, set aside. Drizzle the watercress with a little olive oil and balsamic vinegar, season with a pinch of salt and toss to combine. Set aside.

To build the burgers, spread a dollop of horseradish mayo down on the cut sides of your bun. Place the burger patty down, top with caramelized onions, crumbled blue cheese and watercress. Close the bun and skewer. Serve immediately.

To make the caramelized onions:

Heat the olive oil and butter together in a sauté pan until the butter melts. Add the onions and cook over low heat, stirring often, for 5-10 minutes. Add the pinch of sugar and a season with a little salt. Cover and continue cooking until the onions begin to caramelize, stirring every 5-7 minutes. Uncover the onions and finish cooking until a deep golden brown, stirring often. Season to taste with salt. Set aside.
