Make this rich and savory caramelized onion dip from scratch. Slow-cooked onions create deep sweetness, balanced by a creamy base perfect for your next gathering or game day.

Ingredients

Scale
  • 3 large yellow onions, thinly sliced
  • 2 tablespoons unsalted butter
  • 1 tablespoon olive oil
  • 1 teaspoon granulated sugar
  • 1/2 teaspoon salt, plus more to taste
  • 1/4 teaspoon black pepper
  • 1 teaspoon fresh thyme leaves (or 1/2 teaspoon dried)
  • 8 ounces cream cheese, softened
  • 1 cup sour cream
  • 1/4 cup mayonnaise
  • 1 clove garlic, minced
  • 1 tablespoon Worcestershire sauce

Instructions

  1. Prepare the Onions: In a large, heavy-bottomed skillet, melt the butter and olive oil over medium-low heat. Add the sliced onions, sugar, salt, and pepper. Stir to coat.
  2. Caramelize: Cook the onions slowly, stirring every 5 to 7 minutes. Keep the heat low to prevent burning. This process takes 40 to 50 minutes until the onions are deep brown, sweet, and jammy.
  3. Add Flavor: Stir in the fresh thyme and minced garlic during the last 2 minutes of cooking. Remove the skillet from the heat and let the onions cool slightly.
  4. Mix the Base: In a medium bowl, combine the softened cream cheese, sour cream, mayonnaise, and Worcestershire sauce until smooth.
  5. Combine: Fold the cooled caramelized onions and thyme mixture into the cream cheese base until evenly distributed. Taste and add more salt or pepper if needed.
  6. Chill or Serve Warm: For the best flavor, cover the dip and chill in the refrigerator for at least 2 hours to allow the flavors to meld. You can also serve this warm onion dip immediately after mixing.

Notes

  • For a faster method, you can slow cook the onions in a slow cooker on low for 6 to 8 hours until deeply caramelized.
  • If you want a cheesy variation, mix in 1/2 cup of shredded Gruyere cheese with the cream cheese base.
  • This dip is excellent served warm, especially for party snacks or game day appetizer ideas.
  • Serve this rich and savory dip with sturdy potato chips, pretzel crisps, pita chips, or fresh vegetable sticks like carrots and celery.
