4.7 from 73 reviews

A rich and flavorful caramelized onion dip featuring slow-cooked sweet onions blended with creamy sour cream and softened cream cheese, enhanced with garlic, fresh parsley, and a splash of white wine. Perfect as a warm or chilled accompaniment to chips, bread, or fresh veggies.

Ingredients

Scale

Caramelized Onions

  • 3 medium yellow onions, thinly sliced
  • 2 tbsp salted butter
  • 2 tsp salt
  • 2 tsp sugar
  • 60ml dry white wine

Dip Base

  • 340g sour cream
  • 225g cream cheese, softened

Flavorings

  • 1 clove garlic, grated (optional)
  • Fresh parsley, minced (to taste)
  • Few dashes Worcestershire or soy sauce (to taste)

Instructions

  1. Prepare the butter and onions: Melt the salted butter in a pan over low heat to prevent burning and ensure even cooking.
  2. Caramelize the onions: Add the thinly sliced onions, salt, and sugar to the melted butter. Cook slowly over low heat for about 30 minutes, stirring occasionally, until the onions become jammy, soft, and a deep golden brown.
  3. Deglaze the pan: Pour in the dry white wine in splashes to deglaze the pan, scraping up any browned bits. Allow the wine to reduce fully, intensifying the onion flavor.
  4. Prepare the onions for the dip: Once caramelized, chop the onions finely or snip them with scissors to create a manageable texture for the dip.
  5. Combine cream cheese and sour cream: In a mixing bowl, blend the softened cream cheese and sour cream together until the mixture is smooth and creamy.
  6. Mix all ingredients: Add the caramelized onions, grated garlic (if using), Worcestershire or soy sauce, and minced parsley to the cream mixture. Stir thoroughly and adjust seasoning to taste.
  7. Serve: Serve the caramelized onion dip warm or chilled alongside chips, bread, or your favorite dipping accompaniments.

Notes

  • Cooking the onions slowly over low heat is essential to develop their deep, sweet caramel flavor without burning.
  • The vinegar or acidity in wine helps to balance the sweetness of the onions and adds depth.
  • Garlic is optional but adds an extra layer of flavor if desired.
  • Worcestershire sauce brings umami depth, while soy sauce is a great substitute for a vegan/vegetarian alternative.
  • This dip can be made a day ahead; flavors intensify after resting.
  • Adjust salt and seasoning after mixing the final dip to suit your taste.
