A creamy, cheesy dip featuring caramelized Vidalia onions baked with Parmesan and Gruyère cheeses, perfect for gatherings and quick snacks.

Ingredients

Scale
  • 3 large Vidalia onions, thinly sliced
  • 3 tablespoons unsalted butter
  • 1 cup full-fat sour cream
  • 1/2 cup mayonnaise
  • 1/2 cup freshly grated Parmesan cheese
  • 1/2 cup shredded Gruyère cheese
  • 2 cloves garlic, minced
  • 1 teaspoon fresh thyme, finely chopped (optional)
  • Salt and freshly cracked black pepper, to taste
  • 1 teaspoon Worcestershire sauce (optional)

Instructions

  1. Heat the butter over medium-low heat in a skillet. Add the thinly sliced Vidalia onions and a pinch of salt. Stir occasionally, letting them soften and turn golden brown, about 25-30 minutes. Add a splash of water or a tiny bit of oil if they start to stick.
  2. Preheat the oven to 375°F (190°C).
  3. In a mixing bowl, combine sour cream, mayonnaise, minced garlic, Worcestershire sauce, chopped thyme, and half of the Parmesan cheese. Season with salt and freshly cracked black pepper to taste. Stir until smooth and creamy.
  4. Fold the cooled or slightly warm caramelized onions into the creamy mixture until evenly coated.
  5. Spoon the dip mixture into a baking dish, spreading it evenly. Sprinkle the remaining Parmesan and shredded Gruyère cheese on top.
  6. Bake in the preheated oven for 20-25 minutes until bubbly and golden brown. For an extra crusty top, broil for 1-2 minutes, watching closely to prevent burning.
  7. Let the dip rest for about 5 minutes before serving to thicken.

Notes

Caramelize onions slowly over low heat to avoid burning. Let the dip rest after baking to thicken and enhance flavors. Use high-quality Parmesan (Parmigiano-Reggiano) and creamy Gruyère for best results. Can be made a day ahead by caramelizing onions and mixing the base, then baking fresh before serving.
