Ingredients
- 3 medium yellow onions (approx. 450g), very thinly sliced
- 30g (2 tablespoons) salted butter
- 5g (1 teaspoon) fine sea salt (for onions, adjust to taste later)
- 8g (2 teaspoons) granulated sugar
- 60ml (1/4 cup) dry white wine, such as Sauvignon Blanc or Pinot Grigio
- 340g (1.5 cups) full-fat sour cream
- 225g (8 ounces) full-fat cream cheese, softened to room temperature
- 1 large clove garlic, finely grated (optional, for a sharper zest)
- 15g (2 tablespoons) fresh flat-leaf parsley, finely minced, plus extra for garnish
- 5-10ml (1-2 teaspoons) Worcestershire sauce or dark soy sauce, to taste
Instructions
- In a heavy-bottomed pan or skillet, melt the 30g (2 tablespoons) of salted butter over very low heat. This low temperature is crucial for preventing the butter from browning too quickly and to allow a gentle caramelization process.
- Add the thinly sliced onions, 5g (1 teaspoon) of fine sea salt, and 8g (2 teaspoons) of granulated sugar to the pan. Stir well to coat the onions evenly. The salt helps draw out moisture, aiding in the caramelization, while the sugar enhances the browning process and sweetness. Cook the onions "low and slow," stirring occasionally, for approximately 30 minutes. The goal is for them to become deeply golden brown, incredibly soft, and jammy in texture, indicating full caramelization.
- Once the onions are beautifully caramelized, increase the heat slightly to medium-low. Carefully add 60ml (1/4 cup) of dry white wine to deglaze the pan. Pour it in splashes, scraping up any delicious browned bits (fond) from the bottom of the pan with a wooden spoon. Allow the wine to reduce fully, evaporating almost completely, which intensifies the flavor of the onions and removes any harsh alcohol notes. Remove the pan from heat and let the onions cool for a few minutes.
- For a smoother dip texture, finely chop the caramelized onions on a cutting board or, for a quicker method, snip them into smaller pieces directly in the pan using kitchen scissors. This step ensures the onion pieces are small enough to blend seamlessly into the dip.
- In a separate medium-sized mixing bowl, combine the 340g (1.5 cups) of full-fat sour cream and 225g (8 ounces) of softened full-fat cream cheese. Use a whisk or a rubber spatula to mix them thoroughly until the mixture is completely smooth and free of lumps. Ensure the cream cheese is at room temperature for the best blend.
- Add the cooled, finely chopped caramelized onions, the finely grated garlic (if using), 5-10ml (1-2 teaspoons) of Worcestershire or soy sauce, and 15g (2 tablespoons) of finely minced fresh parsley to the sour cream and cream cheese base. Stir all the ingredients together until they are evenly distributed and well combined.
- Taste the dip and adjust the seasoning as needed. You may want to add a little more salt, a touch more Worcestershire/soy sauce for umami, or even a tiny pinch of sugar if you prefer a sweeter profile. The flavors will deepen as the dip rests.
- Transfer the dip to a serving bowl. Serve it immediately while warm for a comforting treat, or chill it in the refrigerator for at least 30 minutes (preferably longer, up to 2 hours) to allow the flavors to meld beautifully. Garnish with a sprinkle of fresh parsley before serving. Enjoy with your favorite potato chips, toasted baguette slices, crudités, or as a spread for sandwiches.

Tools You’ll Need
- Heavy-bottomed pan or skillet (preferably cast iron or stainless steel)
- Cutting board
- Sharp chef's knife or kitchen scissors
- Mixing bowls (medium and large)
- Whisk or rubber spatula
- Grater (for garlic, if using)
- Measuring cups and spoons
Essential Success Tips
- Always caramelize onions "low and slow." Rushing the process leads to burnt or undercooked onions, sacrificing the deep flavor.
- Ensure your cream cheese is truly at room temperature; this prevents lumps and ensures a silky smooth dip texture.
- Don't skip the deglazing step; it captures all the delicious browned bits from the pan, adding another layer of flavor to the onions.
- Taste and adjust seasoning throughout. The final saltiness will depend on your initial salt use and the Worcestershire/soy sauce.
- For the best flavor, allow the dip to chill in the refrigerator for at least 30 minutes to an hour before serving. This allows the flavors to meld and deepen.
Professional Cooking Secrets
- To achieve ultimate caramelization, add a tiny pinch of baking soda (about 1/8 teaspoon) along with the salt and sugar. It slightly raises the pH, speeding up the Maillard reaction without compromising flavor.
- For an even richer umami punch, consider adding a teaspoon of balsamic glaze or a few drops of truffle oil (if appropriate for the occasion) to the finished dip.
- Use a mandoline slicer for perfectly thin and even onion slices; this ensures uniform caramelization and a superior texture in the finished dip.

Notes
- Storage: Store any leftover dip in an airtight container in the refrigerator for up to 3-4 days.
- Serving Variations: Serve warm by gently reheating in a microwave or oven, stirring occasionally, or enjoy cold.
- Dairy-Free Option: Use plant-based sour cream and cream cheese alternatives for a dairy-free version, ensuring the flavor profile remains balanced.
Frequently Asked Questions
Can I make this dip ahead of time?
Absolutely! This dip is an excellent make-ahead appetizer. In fact, its flavors deepen and improve after chilling in the refrigerator for a few hours or even overnight. Just give it a good stir before serving.
What kind of onions are best for caramelizing?
Yellow onions are ideal for caramelizing due to their higher sugar content, which contributes to their sweet, jammy texture when cooked slowly. Sweet onions like Vidalia can also work but may caramelize faster.
What can I serve with this dip besides chips?
This versatile dip pairs wonderfully with a variety of dippers! Try toasted baguette slices, pita bread, pretzel crisps, fresh vegetable crudités (carrots, celery, bell peppers), or even as a flavorful spread for sandwiches and wraps.
