Make this rich, creamy French Onion Dip from scratch using slow-caramelized onions for deep flavor. This easy appetizer is perfect for game days or parties.

Ingredients

Scale
  • 2 large yellow onions, thinly sliced
  • 2 tablespoons unsalted butter
  • 1 teaspoon olive oil
  • 1/2 teaspoon salt
  • 1/4 teaspoon black pepper
  • 1 teaspoon Worcestershire sauce
  • 1/2 teaspoon dried thyme
  • 1 cup sour cream
  • 1/2 cup cream cheese, softened
  • 1/4 cup mayonnaise
  • 1 clove garlic, minced
  • 1 tablespoon fresh chives, chopped (for garnish)

Instructions

  1. Heat butter and olive oil in a large skillet over medium heat. Add the sliced onions, salt, and pepper.
  2. Cook the onions slowly, stirring occasionally, for 30 to 40 minutes until they are deeply caramelized and sweet. Reduce heat if they start to brown too quickly.
  3. Stir in the Worcestershire sauce and dried thyme during the last 5 minutes of cooking. Remove from heat and let the onions cool completely.
  4. In a medium bowl, combine the sour cream, softened cream cheese, mayonnaise, and minced garlic. Mix until smooth.
  5. Fold the cooled caramelized onions into the sour cream mixture. Mix gently to combine evenly.
  6. Cover the dip and chill in the refrigerator for at least 2 hours to allow the flavors to meld. This step is important for the best flavor.
  7. Before serving, transfer the dip to a serving bowl and garnish with fresh chives. Serve with chips, crackers, or vegetables.

Notes

  • For a quicker version, you can use 1 packet of dry onion soup mix instead of caramelizing fresh onions, but the flavor will be less deep.
  • This dip tastes better if you make it a day ahead.
  • If you prefer a hot onion dip, mix ingredients and bake at 350°F (175°C) for 20 minutes until bubbly.
