Equipment

  • 1 Large frying pan

Ingredients

  • 2 tbsp olive oil extra virgin
  • 2 tbsp butter
  • 5 yellow onions thinly sliced
  • 3 tbsp brandy or cognac
  • 2 tsp balsamic vinegar
  • 2½ tbsp brown sugar
  • 1 250 gram block cream cheese room temperature
  • 1½ cups sour cream
  • 1/3 cup mayonnaise
  • 1½ cups gruyère cheese shredded
  • 1 cup mozzarella shredded
  • 1/2 tsp dried thyme
  • 1/4 tsp garlic powder
  • 1/4 tsp black pepper
  • salt to taste

Instructions

  • Prepare the onions: begin by peeling and slicing the onions.
    To a large non-stick pan set to low/medium heat, add the olive oil and butter.
    Add the sliced onions and begin cooking for 30-45 minutes, stirring often.
    After the onions have been cooking for about 30 minutes, deglaze the pan with the brandy and season with salt and pepper.
    Allow the brandy to reduce, about 2 minutes.
    Add the balsamic vinegar and brown sugar and let simmer until the brown sugar has melted. About 2 minutes.
    Continue cooking for another 15 minutes if needed, just until the onions are deeply golden, thick, and have a jam-like consistency.
    Remove from the heat and set aside until ready to use.
    Sammy's tip: be sure to cook the onions on low/medium heat to avoid them from burning. If you notice the onions have little moisture left and appear to be burning, reduce the heat and deglaze with a tsp or 2 of water.
  • Preheat the oven: once the onions are nearly finished, preheat your oven to 375 °F.
  • Prepare the dip: to a large mixing bowl combine the cream cheese, sour cream, and mayonnaise.
    Using a hand blender or large wooden spoon, mix to combine until you reach a smooth creamy consistency.
    Add the gruyère, mozzarella, dried thyme, garlic powder, a 1/4 tsp of black pepper and mix again.
  • Add the onions: add the caramelized onions and gently mix to combine. Taste to see if you want to add any additional salt.
  • Bake: pour into a large baking dish, cover, and bake for 25-30 minutes, or until bubbling.
  • Serve: with bread, tortilla chips, or fresh veggies.
