Ingredients

1 Tablespoon butter
2 Tablespoons olive oil
2 large yellow onions, finely chopped
1 cup plain Greek yogurt (245g)
1/2 cup sour cream (115g)
1/2 cup mayonnaise (120g)
3 garlic cloves, minced
2 Tablespoons chopped fresh chives
1 teaspoon kosher salt
¼ teaspoon fresh cracked black pepper, to taste

Instructions

Step 1: Caramelize the onions by heating butter and olive oil in a sauté pan over low heat. Add the finely chopped onions and cook, stirring every few minutes, for about 30 minutes until they turn a deep, rich golden color. Remove from heat and transfer to a bowl to cool. This step can be done ahead of time and stored in the fridge.
Step 2: In a mixing bowl, combine Greek yogurt, sour cream, mayonnaise, minced garlic, chopped chives, and kosher salt. Stir in the cooled caramelized onions thoroughly. Taste the mixture and adjust salt and black pepper as needed. For extra garnish, reserve a pinch of chives and some caramelized onions to sprinkle on top before serving. Refrigerate the dip for at least 30 minutes to let the flavors meld.
Step 3: Serve the French Onion Dip with your favorite chips like kettle potato or ruffles, pretzel thins, pita bread, crackers, or fresh veggies. Leftover dip also works wonderfully as a condiment on burgers or sandwiches.

Tips & Variations

For a sweeter caramelized onion flavor, add a pinch of sugar while cooking the onions.
Use shallots instead of onions for a slightly different but delicious taste.
Substitute mayonnaise with extra sour cream for a lighter texture.
Try adding a splash of Worcestershire sauce for an umami boost.

Storage

Store the French Onion Dip in an airtight container in the refrigerator for up to 5 days. Before serving leftovers, give it a good stir. The dip is best enjoyed cold but can be brought to room temperature if preferred.

FAQs

Can I make the caramelized onions ahead of time?

Yes, caramelized onions can be made in advance and refrigerated for up to 3 days. Just store them in an airtight container until you’re ready to use.

Is Greek yogurt necessary in this recipe?

Greek yogurt adds creaminess and tang while lightening the dip. You can substitute with regular plain yogurt, but the dip may be less thick and creamy.
