Step‑by‑Step Instructions for Caramelized Onion Dip
Step 1: Caramelize the Onions
In a large skillet, melt 2 tablespoons of unsalted butter over medium heat. Once it's shimmering, add 2 cups of thinly sliced sweet onions and sprinkle a pinch of salt and pepper. Reduce the heat to low and cook slowly, stirring frequently, for 30-60 minutes until the onions are deeply browned and caramelized. The goal is a rich golden color and a sweet aroma permeating your kitchen.
Step 2: Prepare the Dip Base
While the onions are cooking, in a mixing bowl, whisk together 1 cup of sour cream, ½ cup of mayonnaise, and 1 teaspoon of garlic powder. Mix until smooth and creamy. This base brings a tangy richness that beautifully complements the sweet caramelized onions, so make sure it's well combined with a few twists of fresh black pepper to taste.
Step 3: Combine Ingredients
Once the onions have reached that luscious caramelized state, carefully add them to the creamy dip base. Use a spatula to gently fold them in until evenly incorporated; the warm onions will help meld the flavors together. Taste and adjust the seasoning if needed, adding more salt or pepper for enhancement.
Step 4: Chill and Serve
Transfer the combined mixture to a serving bowl and cover it with plastic wrap. Allow the dip to cool at room temperature for about 20 minutes, then refrigerate for at least 1 hour. Chilling is essential for the best flavor—this Caramelized Onion Dip pairs excellently with crunchy chips, fresh vegetable sticks, or even served in a hollowed sourdough loaf for an eye-catching presentation.

You can caramelize the onions up to 24 hours in advance and store them in the refrigerator in an airtight container.

When it's time to serve, simply mix the cooled caramelized onions into the creamy base, refrigerate for at least 1 hour to chill, and garnish as desired. By preparing ahead, you ensure that this delicious dip is just as mouthwatering and ready for any occasion!
