Ingredients
Scale
For the Caramelized Onions
- 2 tablespoons unsalted butter
- 2 tablespoons olive oil
- 2 medium sweet onions, finely chopped
- 1 teaspoon kosher salt (or more to taste)
For the Dip
- 1 ⅓ cups plain Greek yogurt (or substitute with sour cream)
- ½ cup Kewpie mayonnaise (or use regular mayonnaise)
- ⅓ cup cornichons, finely chopped (or use dill pickles)
- 2 ½ tablespoons green onion, finely chopped (reserve 1 pinch for topping)
- 2 cloves garlic, grated
Instructions
- Caramelize the Onions: In a non-stick skillet, heat the olive oil and butter together over low heat until the butter melts. Add the finely chopped sweet onions and sprinkle with kosher salt. Stir occasionally and cook slowly over low heat for 30–35 minutes until the onions become tender and turn a rich caramel brown. Remove from heat and let cool completely.
- Mix the Dip Base: While the onions are cooking, combine Greek yogurt, mayonnaise, grated garlic, chopped cornichons, and most of the green onions (reserve a pinch for garnish) in a mixing bowl. Once the caramelized onions have cooled, fold them into the dip mixture, reserving a tablespoon for topping if desired. Mix thoroughly to combine all flavors.
- Chill the Dip: Transfer the dip to a serving bowl. Garnish with the reserved caramelized onions and green onion pinch. Cover and refrigerate for at least 15 minutes before serving to let the flavors meld. The dip can also be made a day ahead for enhanced taste.
- Serve: Serve chilled with potato chips, fresh cut vegetables, or your preferred dipping snacks.
Notes
- Cooking the onions slowly over low heat is key to developing their deep caramelized flavor without burning.
- Kewpie mayonnaise adds a slightly different tang and creaminess but regular mayonnaise works just as well.
- Cornichons add a nice crunch and acidity; dill pickles are a good substitute if unavailable.
- The dip tastes even better after resting overnight in the fridge.
- For a thicker dip, you can strain some whey from the Greek yogurt before mixing.
