How to caramelize onions

1. Peel and cut the onions in half, then slice into thin, even strips.

2. Place a large skillet over medium-low heat and add butter.

3. Add the onions and stir to coat them in the butter.

4. Stir every few minutes to prevent burning. The onions will soften and turn golden brown over 30–45 minutes.

5. If they start sticking or browning too fast, lower the heat and add a splash of chicken or vegetable broth to deglaze the pan.

6. Once the onions reach a deep brown, jam-like consistency, they’re done!

How to make the dip

1. After caramelizing, place the onions in a medium bowl and refrigerate to cool.

2. In a large bowl, combine sour cream and mayonnaise.

3. Stir in the cooled caramelized onions.

4. Transfer to your preferred serving dish, top with fresh chives, and serve with chips or crostinis.
