What to keep in mind.
7 tips from the recipe — small details that make a real difference to the final dish.
- 1Use a mandoline or sharp knife for evenly thin onion slices so they caramelize uniformly.
- 2Cook the onions on medium-low heat, not higher, to avoid burning the sugars before they caramelize.
- 3Stir the onions every 5 minutes and scrape up any browned bits from the pan for deeper flavor.
- 4Let the dip chill for at least 30 minutes (or overnight) to allow the flavors to meld fully.
- 5If making ahead, store the dip in an airtight container in the fridge for up to 4 days.
- 6For a thicker dip, drain excess liquid from the caramelized onions before folding into the cream base.
- 7Fold the onions in gently to keep the dip creamy without breaking down the onion strands too much.
