Instructions

  1. Step 1: Finely chop 1 large onion and mince 2 garlic cloves; cook with 1 tbsp balsamic vinegar and 1 tbsp brown sugar in a skillet over medium-low heat for 15 minutes until deeply caramelized and golden.
  2. Step 2: In a bowl, combine 1 lb ground beef, 1 tsp salt, 1/2 tsp black pepper, 1/2 tsp smoked paprika, and 1 tsp Worcestershire sauce; gently mix with hands until just incorporated.
