Ingredients

BARBECUED ONIONS

  • 1/2 tablespoon olive or canola oil
  • 6 slices lean smoky bacon, chopped
  • 4 large sweet onions, halved lengthwise and sliced
  • 1 large bay leaf
  • Salt and coarse pepper
  • 2 cloves garlic, chopped
  • 1/2 cup chicken or turkey stock
  • 1/4 cup ketchup
  • 2 tablespoons (packed) brown sugar
  • 2 tablespoons cider vinegar
  • 2 tablespoons Worcestershire sauce
  • 1 tablespoon spicy brown or Dijon mustard
  • 1 teaspoon Tabasco or other hot sauce

BEEF & PORK BURGERS

  • 1 pound ground beef (80% lean)
  • 1 pound ground pork
  • Kosher salt and coarse pepper
  • 3 - 4 tablespoons grated onion and its juice
  • About 3 tbsp. Worcestershire sauce
  • 2 cloves garlic, grated
  • 1 1/2 teaspoons ground cumin
  • 1 1/2 teaspoons ground coriander
  • 1 1/2 teaspoons smoked paprika
  • Olive oil or canola oil
  • 4 slices sharp white cheddar (optional)
  • Lettuce leaves and sliced pickles, for garnish
  • 4 kaiser or other burger rolls, halved and lightly toasted

Preparation

In a medium skillet, heat the oil over medium. Add the bacon and cook, stirring occasionally, until crispy at the edges, about 5 minutes. Transfer the bacon to a plate. Pour off all but 2 tbsp. drippings. Add the onions and bay leaf; season with pepper. Cook until the onions are tender, about 5 minutes. Add the garlic and cook, stirring occasionally, until the onions are light golden and just beginning to caramelize, about 15 minutes. Stir in the stock, ketchup, brown sugar, vinegar, Worcestershire, mustard and hot sauce. Simmer over low heat, stirring often, until the mixture thickens a bit, about 3 minutes. Keep warm over low heat, adding a splash of water if it gets too thick. Season with salt and more hot sauce, if desired. Just before serving, stir in the bacon and discard the bay leaf.

In a large bowl, combine the ground meats; season with kosher salt and coarse black pepper. Add the onion and juice, Worcestershire, garlic, cumin, coriander and paprika; drizzle with a little oil, then mix to combine. Form 4 large patties (thinner in the centers for even cooking).

Preheat a griddle or large cast-iron skillet over medium-high. When the pan is very hot, add the burgers. Cook, turning once, about 12 minutes for medium well. Add the cheese, if using, during the last minute or two of cooking. Cover the pan to melt the cheese.

Place the lettuce and pickles on the bun bottoms. Add the patties, a mound of bacon-barbecued onions and the bun tops.
