What you will need
This recipe uses 5 simple ingredients that you can find at any grocery store:
- 3 large yellow onions thinly sliced
- 1 cup full-fat sour cream
- 4 oz cream cheese softened
- 1 tsp salt
- 2 tbsp olive oil
Step by step instructions
Step 1: Caramelize the Onions
Heat olive oil in a large skillet over medium-low heat. Add sliced onions and salt, stirring occasionally for 30 to 35 minutes until onions are deeply golden brown, jammy, and sweet. Do not rush this step over high heat. Let cool completely.
Step 2: Blend the Base
In a mixing bowl beat the softened cream cheese until completely smooth with no lumps. Add the sour cream and stir until fully combined and creamy. Taste and adjust salt if needed.
Step 3: Fold and Chill
Fold the cooled caramelized onions into the cream cheese mixture until evenly distributed. Cover and refrigerate for at least 30 minutes before serving to let the flavors fully develop. Serve with chips or vegetables.
Easy substitutions
Missing an ingredient? Here are some swaps that work perfectly:
- full-fat sour cream → Greek yogurt for a tangier and higher-protein version of the dip
- yellow onions → shallots for a milder and more delicate caramelized flavor
Common mistakes to avoid
Watch out for these pitfalls that can affect your results:
- Turning the heat up to speed up caramelization burns the onions and creates bitter acrid notes instead of deep sweet caramel flavor
- Folding in the hot onions without cooling them first melts the cream cheese and sour cream base into a loose runny dip
