Rich and creamy caramelized onion dip is the perfect party appetizer. Made with sweet caramelized onions and a savory, tangy base, it's a crowd-pleaser!
Melt the butter over medium-high heat and add the sliced onions, stirring occasionally. Once the onions begin to brown, reduce the heat to medium-low and continue cooking until they are golden and caramelized. This process typically takes 20-25 minutes.
In a food processor, add the cream cheese, sour cream, mayonnaise, and season with salt and pepper. Process until smooth.
Once your onions are caramelized, let them cool off for 5 minutes, and then add to the dip in the processor and pulse for just a second to mix the onions in.
Regrigerate for 30 minutes and serve with your favorite dippers.
