Ingredients

Scale
  • 2 large yellow onions, thinly sliced
  • 2 tablespoons unsalted butter
  • 1 teaspoon granulated sugar
  • 1/2 teaspoon salt, plus more for seasoning
  • 1/4 teaspoon black pepper
  • 1 tablespoon fresh thyme leaves
  • 1 clove garlic, minced
  • 8 ounces cream cheese, softened
  • 1 cup sour cream
  • 1/4 cup mayonnaise
  • 1 teaspoon Worcestershire sauce

Instructions

  1. Melt the butter in a large skillet over medium heat. Add the sliced onions and sugar. Cook slowly, stirring occasionally, for 30 to 40 minutes until the onions are deep golden brown and sweet. Do not rush this step; low and slow creates the best flavor.
  2. Stir in the salt, pepper, thyme, and minced garlic during the last 2 minutes of cooking the onions. Remove the skillet from the heat and let the onion mixture cool slightly.
  3. In a medium bowl, combine the softened cream cheese, sour cream, mayonnaise, and Worcestershire sauce. Mix until smooth.
  4. Fold the cooled caramelized onion mixture into the cream cheese base until everything is evenly combined.
  5. Taste the dip and add more salt or pepper if needed.
  6. For the best flavor, cover the dip and chill in the refrigerator for at least 2 hours before serving.
  7. Serve your homemade caramelized onion dip cold with chips, crackers, or fresh vegetables.

Notes

  • For a warm, baked version, transfer the mixed dip to an oven-safe dish, top with a sprinkle of Gruyere cheese if desired, and bake at 375°F (190°C) for 15 minutes until bubbly.
  • This dip pairs well with sturdy potato chips, pretzel crisps, or slices of toasted baguette.
  • You can make the caramelized onions up to two days ahead and store them in the refrigerator.
