Ingredients

Instructions

  1. Step 1: Heat 1 tbsp olive oil in a large skillet over medium heat. Add 2 medium thinly sliced yellow onions and sauté for 15 minutes, stirring occasionally, until onions become soft and caramelized to a deep golden brown.
  2. Step 2: Stir in 1/4 cup whiskey, 2 tbsp brown sugar, and 3 minced garlic cloves to the onions. Cook for another 5 minutes until the liquid reduces and the glaze thickens, then remove from heat.
  3. Step 3: In a mixing bowl, combine 1 lb beef sirloin cubes with 1 tbsp olive oil, 1 tbsp soy sauce, 1 tsp salt, and 1/2 tsp black pepper. Toss to coat evenly.
  4. Step 4: Thread the beef cubes onto 8 soaked wooden skewers, alternating with small spoonfuls of the whiskey-glazed caramelized onions.
  5. Step 5: Preheat grill or grill pan over medium-high heat. Grill the skewers for 3-4 minutes per side, basting occasionally with any remaining glaze, until beef reaches desired doneness and edges are slightly charred.
  6. Step 6: Serve hot with any leftover glaze spooned over the top for extra flavor.
