A rich and comforting baked dip combining sweet Vidalia onions and nutty Gruyère cheese, perfect for party snacks with crispy crostini.

Ingredients

Scale
  • 3 medium Vidalia onions, thinly sliced
  • 1 ½ cups grated Gruyère cheese
  • 8 ounces cream cheese, softened
  • ½ cup sour cream
  • ¼ cup mayonnaise
  • 2 cloves garlic, minced
  • 2 tablespoons olive oil or butter
  • 1 teaspoon fresh thyme, chopped (optional)
  • Salt and black pepper to taste
  • 1 baguette, sliced thinly for crostini
  • Extra virgin olive oil for brushing crostini

Instructions

  1. Heat 2 tablespoons of olive oil or butter in a large skillet over medium-low heat. Add the thinly sliced Vidalia onions and a pinch of salt. Stir occasionally, letting the onions soften and turn golden brown, about 20-25 minutes.
  2. Preheat the oven to 375°F (190°C). Slice the baguette thinly, about ¼ inch thick. Arrange slices on a baking sheet and brush lightly with extra virgin olive oil. Toast in the oven for 8-10 minutes until golden and crispy.
  3. In a mixing bowl, combine softened cream cheese, sour cream, mayonnaise, and minced garlic. Mix well until smooth. Season lightly with salt and freshly cracked black pepper.
  4. Fold the cooled caramelized onions and grated Gruyère cheese into the creamy mixture. Stir in fresh thyme if using.
  5. Transfer the mixture to an 8×8 inch baking dish and spread evenly. Bake in the preheated oven for about 20 minutes or until the top is golden and bubbly.
  6. Let the dip cool for 5 minutes before serving alongside the crispy crostini.

Notes

Caramelize onions slowly over medium-low heat to bring out sweetness. Use day-old baguette for crispier crostini. Let cream cheese soften at room temperature for smooth mixing. For a lighter dip, substitute sour cream with plain Greek yogurt. To speed caramelization, add a pinch of baking soda but classic slow cooking yields best flavor.
