  • 1/3 cup light brown sugar
  • 1 tablespoon Worcestershire sauce
  • 1 teaspoon apple cider vinegar
  • 1/2 cup ketchup
  • 1/2 cup BBQ sauce

ingredients

For the burgers:

  • 20 ounces ground beef
  • 1/2 cup panko breadcrumbs
  • 1/2 cup heavy cream
  • 1 large egg, beaten
  • 8 ounce block mozzarella cheese, sliced into thick pieces
  • 1 yellow onion, finely diced (for meatloaf mixture)
  • 1 tablespoon unsalted butter
  • 1 tablespoon Worcestershire sauce
  • Kosher salt, to taste
  • Burger seasoning of choice

ingredients

For topping & assembly:

  • 1 yellow onion, sliced `
  • Flour + seasoned salt, for dredging (or use store-bought French fried onions)
  • Brioche buns, toasted

Method

  • Step 1

    Make the tomato glaze: In a blender, combine Red Gold Tomatoes with Hatch Chiles, brown sugar, Worcestershire sauce, and apple cider vinegar. Blend until smooth. Add in ketchup and BBQ sauce and blend again. Pour into a saucepan and bring to a simmer. Cook uncovered for 30–40 minutes, stirring occasionally, until thickened.

  • Step 2

    Caramelize onions for burger mix: In a skillet over medium heat, melt butter and sauté finely diced onion with a pinch of salt and 1 tablespoon Worcestershire sauce until caramelized (about 8–10 minutes). Let cool slightly.

  • Step 3

    Make the meatloaf patties: In a large mixing bowl, combine ground beef, panko, heavy cream, beaten egg, caramelized onions, and burger seasoning. Mix until just combined.

  • Step 4

    Stuff the burgers: Divide the mixture in half and form 4 bottom patties. Add sliced mozzarella to the center of each, then cover with remaining meat mixture. Press and seal the edges to create a stuffed burger patty.

  • Step 5

    Grill the burgers: Preheat grill to medium heat. Grill each burger for 5–6 minutes per side, flipping 2–3 times for even cooking (total ~15–18 minutes). In the last 5 minutes, spoon glaze over each burger and move them to the top rack or indirect heat to let the sauce tack up.

  • Step 6

    Fry crispy onions (or use store-bought): Coat sliced onions in seasoned flour and fry in oil until golden and crisp. Drain on paper towels.

  • Step 7

    Place brioche buns on the grill for 1–2 minutes, until golden.

  • Step 8

    Assemble: Place each burger on a toasted bun, top with crispy fried onions, and serve hot. Use leftover glaze as a dipping sauce for extra flavor.
