  • 2 large sweet onion chopped
  • 1 tbsp olive oil
  • 1 tbsp butter
  • pinch granulated sugar
  • 2 tbsp red wine
  • 4 strips bacon cooked
  • ½ cup Fontina cheese shredded
  • ½ cup Gruyere cheese shredded
  • cup light sour cream
  • ½ cup non-fat plain Greek yogurt
  • pinch salt and pepper
  • 1-2 tsp red pepper flakes optional
  • 1-2 tsp fresh thyme, plus more for garnish


  • Make caramelized onions. Peel and chop onions. Melt butter and olive oil in skillet over medium heat. Cook onions for 5 minutes until they soften and become translucent. Add a pinch of granulated sugar and keep cooking, stirring often. After about 15-20 minutes the onions will start to develop a nice golden brown color once they lose most of their moisture. Turn down the heat to a med-low and continue cooking for another 15-20 minutes until the onions start to give off a nutty aroma. Deglaze pan with red wine and cook for another 2-3 minutes until wine reduces.
  • While the onions are cooking, make the bacon. Crumble and set aside.
  • In a medium bowl, mix together shredded cheeses, sour cream, greek yogurt, salt/pepper, red pepper flakes, and thyme. Add caramelized onions and stir until combined.
  • Transfer to a cast iron skillet or shallow baking dish. Bake for 20-25 minutes or until cheese is melted and the top of the dip is golden brown.
  • Remove from oven and garnish with fresh thyme.
