Black Pepper Blue Cheese Burger with Onion Jam

Blue cheese needs something sweet and dark beside it. A stovetop onion jam with balsamic vinegar does the job. Don't rush those onions. Press coarse pepper onto the patties so it forms a crust instead of scorching loose in the skillet.

Ingredients Method

Ingredients
  

  • 2 large yellow onions thinly sliced
  • 1 tbsp unsalted butter
  • 1 tbsp brown sugar
  • 2 tbsp balsamic vinegar
  • 2 tbsp water
  • 1 1/2 lbs 80/20 ground beef
  • 1 tsp kosher salt
  • 2 tsp coarsely cracked black pepper
  • 4 oz blue cheese crumbled
  • 4 pretzel hamburger buns
  • 1 cup baby spinach

Method
 

  1. Melt the butter in a skillet over medium-low heat and cook the onions for 15 minutes until soft and golden.
  2. Stir in the brown sugar, balsamic vinegar and water and cook for 5 to 7 minutes until the onions are dark, sticky and nearly dry.
  3. Shape the beef into 4 patties, season with salt and press the cracked pepper onto both sides.
  4. Heat a separate heavy skillet over medium-high heat and cook the patties for 4 to 5 minutes on the first side.
  5. Flip and cook for another 4 to 5 minutes without pressing until the centers reach 160°F.
  6. Divide the blue cheese over the patties, cover the skillet for 1 minute and let it soften without fully disappearing.
  7. Toast the split pretzel buns for 1 minute, then build each with spinach, one patty and a generous spoonful of onion jam.
