A rich and creamy French onion dip featuring slow caramelized onions blended with sour cream and mayonnaise, perfect for any occasion and crowd-pleasing.

Ingredients

Scale
  • 2 large yellow onions, thinly sliced
  • 2 tablespoons unsalted butter
  • 1 tablespoon olive oil
  • 1 teaspoon garlic powder
  • 1 teaspoon Worcestershire sauce
  • 1 cup full-fat sour cream
  • 1/2 cup mayonnaise
  • 1/2 teaspoon salt, or to taste
  • 1/4 teaspoon freshly ground black pepper
  • 2 tablespoons finely chopped chives or green onions (optional)

Instructions

  1. Peel and thinly slice 2 large yellow onions into 1/8-inch thick slices.
  2. Heat a large skillet over medium heat and add 2 tablespoons unsalted butter and 1 tablespoon olive oil. Melt the butter without browning.
  3. Add the sliced onions to the skillet and stir to coat with butter and oil. Cook slowly, stirring every few minutes, for 20-25 minutes until onions are soft and golden brown. Lower heat if onions brown too fast.
  4. Sprinkle 1 teaspoon garlic powder and 1 teaspoon Worcestershire sauce over the onions. Stir and cook for another 5 minutes until deeply caramelized and fragrant. Remove from heat and let cool.
  5. In a mixing bowl, whisk together 1 cup sour cream and 1/2 cup mayonnaise until smooth. Season with 1/2 teaspoon salt and 1/4 teaspoon black pepper.
  6. Fold the cooled caramelized onions into the sour cream mixture. Stir in 2 tablespoons chopped chives or green onions if using.
  7. Cover and refrigerate the dip for at least 1 hour, ideally 2-3 hours, to let flavors meld.
  8. Stir before serving and enjoy with chips, veggies, or crackers.

Notes

Use medium heat to avoid burning onions. Chill dip for best flavor. Caramelized onions can be made ahead and stored up to 3 days. For vegan version, substitute dairy ingredients with plant-based alternatives. Greek yogurt can replace mayo and sour cream for a lighter dip.
