Make the best appetizer dip for your next gathering with this rich and creamy homemade caramelized onion dip. Forget the store-bought mix; this recipe uses slowly cooked onions for deep, savory flavor.

Ingredients

Scale
  • 3 large yellow onions, thinly sliced
  • 2 tablespoons olive oil
  • 1 tablespoon unsalted butter
  • 1/2 teaspoon salt, plus more to taste
  • 1/4 teaspoon black pepper
  • 8 ounces cream cheese, softened
  • 1 cup sour cream
  • 1/4 cup mayonnaise
  • 1 teaspoon Worcestershire sauce
  • 1/2 teaspoon garlic powder
  • 1/4 cup shredded Gruyère cheese (optional, for gourmet flavor)

Instructions

  1. Caramelize the Onions: Heat the olive oil and butter in a large, heavy-bottomed skillet over medium-low heat. Add the sliced onions and 1/2 teaspoon of salt. Cook slowly, stirring every 5 to 10 minutes, for 45 to 60 minutes until the onions are deep brown, jammy, and sweet. Do not rush this step; low and slow builds the flavor.
  2. Cool the Onions: Remove the caramelized onions from the heat and spread them on a plate lined with paper towels to drain excess oil. Let them cool for at least 15 minutes.
  3. Prepare the Dip Base: In a medium bowl, beat the softened cream cheese until smooth. Add the sour cream, mayonnaise, Worcestershire sauce, garlic powder, pepper, and Gruyère cheese if you are using it. Mix until just combined.
  4. Combine: Fold the cooled caramelized onions into the cream cheese mixture. Taste the dip and add more salt or pepper if needed.
  5. Chill: Cover the bowl and refrigerate the dip for at least 2 hours to allow the flavors to fully meld. This step is key for the ultimate caramelized onion dip experience.
  6. Serve: Serve cold or at room temperature with your favorite chips, crackers, or crisp vegetables.

Notes

  • For a baked caramelized onion dip, transfer the mixed dip to an oven-safe dish, top with a sprinkle of Parmesan, and bake at 375°F (190°C) for 15 minutes until bubbly.
  • If you are short on time, use shallots instead of onions; they caramelize slightly faster.
  • This dip tastes even better the next day, making it a great make-ahead party dip.
