Step‑by‑Step Instructions for Caramelized Onion Dip
Step 1: Melt the Butter
Begin by melting 2 tablespoons of butter in a large skillet over medium heat, allowing it to foam slightly. This will serve as the foundation for your Caramelized Onion Dip. Once melted, ensure the skillet is evenly coated to prevent the onions from sticking, setting the stage for perfect caramelization.
Step 2: Sauté the Onions
Add 2 cups of finely chopped sweet or yellow onions to the skillet. Sprinkle with a pinch of salt and pepper, then reduce the heat to low. Stir the onions well to coat them in butter. Cook the onions slowly for 30 to 60 minutes, stirring frequently, until they turn a deep golden brown and develop a sweet aroma—this is when their flavor truly shines.
Step 3: Cool the Onions
Once the onions have reached that rich, caramelized state, remove the skillet from heat and let the onions cool slightly. This prevents the dip from getting too warm later on. You can transfer them to a plate or bowl if you want to speed up the cooling process before mixing them into the creamy base.
Step 4: Prepare the Dip Base
In a medium-sized mixing bowl, combine 1 cup of sour cream, ½ cup of mayonnaise, and ½ teaspoon of garlic powder. Stir these ingredients together until smooth and well-blended. This creamy mixture is the heart of your Caramelized Onion Dip, so take your time to ensure it’s perfectly combined.
Step 5: Combine and Mix
Once the onions have cooled, fold them into the dipped base mixture gently. Use a spatula to mix everything until the caramelized onions are evenly distributed. The warmth and sweetness of the onions will infuse into the creamy base, creating a flavorful and inviting Caramelized Onion Dip that’s irresistible.
Step 6: Chill and Serve
For the best flavor, cover the dip and refrigerate for at least 30 minutes to allow the flavors to meld. However, this dip can also be made a day ahead for easy entertaining! Serve your chilled Caramelized Onion Dip with chips, veggies, or warm bread for a delightful appetizer everyone will love.

Caramelized Onion Dip Recipe FAQs
