Ingredients
Scale
2 large yellow onions, thinly sliced
2 tablespoons unsalted butter
1 teaspoon salt
1/2 teaspoon sugar
16 ounces sour cream, full fat
4 ounces cream cheese, softened
1 teaspoon Worcestershire sauce
1/2 teaspoon garlic powder
1/4 teaspoon black pepper
Instructions
Melt the butter in a large, heavy-bottomed skillet over medium-low heat. Add the sliced onions, salt, and sugar.
Cook the onions slowly, stirring occasionally, for 45 to 60 minutes until they are deeply caramelized and dark brown. This slow cooking develops the rich, sweet flavor.
Remove the onions from the heat and let them cool completely. You can speed this up by spreading them on a plate.
In a medium bowl, combine the cooled caramelized onions, sour cream, softened cream cheese, Worcestershire sauce, garlic powder, and black pepper.
Mix all ingredients together until smooth and well combined. Taste and adjust seasoning if needed.
Cover the dip and refrigerate for at least 2 hours, or preferably overnight, to allow the flavors to fully meld. This step is key for the best party dip flavor.
Serve cold with chips, crackers, or fresh vegetables.
Notes
For an even richer flavor, substitute half of the sour cream with plain Greek yogurt.
If you need a quick appetizer, you can use a store-bought French onion soup mix, but the flavor will not match this from scratch dip.
This dip is excellent served warm; combine ingredients and bake at 350°F (175°C) for 20 minutes until bubbly for a hot onion dip baked version.
