Caramelized Onion Dip

Why You’ll Love This Recipe

This dip is rich, velvety, and bursting with caramelized flavor. The onions cook down into a sweet, jammy consistency that pairs beautifully with the tanginess of sour cream and cream cheese. A splash of white wine and Worcestershire or soy sauce adds savory depth, while fresh parsley brightens everything up. It’s easy to make ahead of time, so you can focus on entertaining while still serving something impressive.

Ingredients

(Tip: You’ll find the full list of ingredients and measurements in the recipe card below.)

3 medium yellow onions
2 tablespoons salted butter
2 teaspoons each salt and sugar
1/4 cup dry white wine
12 ounces sour cream
8 ounces cream cheese, softened
1 clove fresh garlic, grated (optional)
Fresh flat-leaf parsley, minced, to taste
A few dashes of Worcestershire sauce or soy sauce, to taste

Directions

1. Slice the onions thinly.
2. In a large skillet, melt butter over medium-low heat. Add onions, salt, and sugar. Cook slowly, stirring occasionally, for 30–40 minutes until onions are deeply golden and caramelized.
3. Deglaze the pan with white wine, scraping up any browned bits. Cook for 2–3 minutes until liquid has mostly evaporated. Remove from heat and let onions cool slightly.
4. In a large bowl, combine sour cream, cream cheese, garlic (if using), and Worcestershire or soy sauce. Mix until smooth.
5. Fold in the caramelized onions and parsley, adjusting seasoning to taste.
6. Chill in the refrigerator for at least 1 hour before serving to let flavors meld.

Storage/Reheating

Store dip in an airtight container in the refrigerator for up to 4 days. Stir before serving, as it may thicken slightly. This dip should not be frozen, as the dairy may separate when thawed. Serve chilled or at room temperature—no reheating necessary.

FAQs

Can I make this dip ahead of time?

How long does it take to caramelize onions properly?

Around 30–40 minutes over medium-low heat for deep golden color and sweet flavor.

What can I serve with this dip?

Potato chips, pita chips, baguette slices, or fresh veggies like carrots and celery.

Do I have to use wine?
