Caramelized Onion Dip Sour Cream (Printer-friendly)

Creamy blend of caramelized onions, tangy sour cream, and fresh chives for flavorful snacking or spreads.

# Required Ingredients:

→ Onions

01 - 2 large yellow onions, finely diced
02 - 2 tablespoons unsalted butter
03 - 1 tablespoon olive oil
04 - ½ teaspoon kosher salt
05 - ¼ teaspoon freshly ground black pepper
06 - ½ teaspoon sugar

→ Dip Base

07 - 1½ cups sour cream, full-fat
08 - ½ cup mayonnaise
09 - 1 teaspoon Worcestershire sauce
10 - 1 teaspoon garlic powder
11 - ½ teaspoon onion powder

→ Fresh Herbs

12 - ¼ cup fresh chives, finely chopped
13 - 1 tablespoon fresh parsley, finely chopped

# How-To Steps:

01 - In a large skillet over medium-low heat, melt butter with olive oil. Add diced onions, salt, pepper, and sugar, stirring occasionally until deeply golden and caramelized, approximately 30 to 35 minutes. Reduce heat if onions brown too quickly. Transfer to room temperature to cool completely.
02 - In a medium mixing bowl, whisk together sour cream, mayonnaise, Worcestershire sauce, garlic powder, and onion powder until smooth and uniform.
03 - Fold cooled caramelized onions, chives, and parsley into the dip base mixture. Mix thoroughly to combine all ingredients evenly.
04 - Taste the dip and adjust seasoning as needed with additional salt, pepper, or spices to achieve desired flavor profile.
05 - Cover dip and refrigerate for at least 1 hour, allowing flavors to meld and develop complexity.
06 - Transfer to serving bowl, garnish with additional fresh chives, and serve chilled alongside chips, crackers, or fresh vegetables.

# Expert Suggestions:

01 -
  • The deep, almost jammy sweetness of caramelized onions transforms sour cream into something way more interesting than ranch powder ever could.
  • It actually tastes better the next day, which means you can make it ahead and actually enjoy your party instead of stress-cooking.
  • Works as a dip, spread, or topping—this one quietly becomes the thing people keep coming back to throughout the meal.
02 -
  • Caramelizing onions is a test of patience, not speed—low heat for a full half hour is what transforms them into something special, and no shortcut actually works.
  • If you fold in the onions while they're still hot, the sour cream can separate slightly and the texture turns thin instead of creamy, so let them cool completely.
03 -
  • Stir your onions every 5 minutes or so instead of constantly—this prevents them from sticking while still letting them caramelize properly.
  • If you're making this for a crowd, double the recipe; it keeps beautifully for 3 days refrigerated and people truly do eat it faster than anything else on the table.
