Caramelized Onion Dip with Greek Yogurt and Cornichorns Recipe

Introduction

Caramelized onion dip is a deliciously rich and creamy treat perfect for any gathering. With the deep sweetness of slow-cooked onions combined with tangy yogurt and mayonnaise, it’s an irresistible snack that pairs wonderfully with chips or fresh veggies.

Ingredients

• 2 tablespoons unsalted butter
• 2 tablespoons olive oil
• 2 medium sweet onions, finely chopped
• 1 ⅓ cup plain Greek yogurt (or use 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
• 2 cloves garlic, grated
• 1 teaspoon kosher salt (more to taste)

Instructions

1. Step 1: In a non-stick skillet, heat olive oil and butter over low heat until the butter is melted. Add the chopped onions and stir occasionally. Sprinkle with salt and cook over low heat, stirring every few minutes until the onions reach a deep caramel color, about 30-35 minutes. Remove from heat and let cool completely.
2. Step 2: While the onions cook, combine the Greek yogurt, mayonnaise, green onion (reserve a pinch for topping), cornichons, garlic, salt, and the caramelized onions (reserve a tablespoon for topping if desired) in a bowl. Mix well to blend all ingredients evenly.
3. Step 3: Transfer the dip to a serving bowl and top with the reserved caramelized onions and green onion. Cover and refrigerate for at least 15 minutes to allow flavors to meld. The dip can be made a day ahead for even better flavor.
4. Step 4: Serve chilled with potato chips, fresh-cut vegetables, or your favorite dippers.

Tips & Variations

• For a richer flavor, substitute the plain Greek yogurt with sour cream or use all mayonnaise if preferred.
• Try adding a pinch of smoked paprika or cayenne pepper for a subtle smoky or spicy kick.
• Use sweet onions like Vidalia for a naturally sweeter dip, enhancing the caramelization.
• If you don’t have cornichons, finely chopped dill pickles work well as a substitute.

Storage

Store the caramelized onion dip in an airtight container in the refrigerator for up to 3 days. Before serving, stir well and chill if needed. This dip is best enjoyed cold and should not be left out for long periods.

FAQs

Can I use regular onions instead of sweet onions?

Yes, you can use regular yellow or white onions, but sweet onions will provide a milder, sweeter flavor that enhances the dip’s taste.

Is it necessary to caramelize the onions slowly?

Yes, cooking the onions slowly over low heat allows their natural sugars to develop fully, resulting in deeper flavor and softness that is essential for this dip.

Instructions

1. 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.
2. 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.
3. 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.
4. 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.
