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.
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.
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.
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.
Mix the Base: In a medium bowl, combine the softened cream cheese, sour cream, mayonnaise, and Worcestershire sauce until smooth.
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.
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.
