Caramelized French Onion Dip

I love a good dip, especially one that can hold its own with a bag of chips, and this Caramelized French Onion Dip is one I come back to again and again. It’s made with slowly cooked onions that turn soft and golden, then mixed into a creamy, tangy base with just a handful of simple ingredients.

This is a from-scratch French onion dip with no packets or shortcuts. I let the onions cook low and slow until they’re sweet and jammy, then fold them into sour cream with garlic, herbs, and chives. It’s rich, savory, and scoopable, the kind of dip that works just as well for parties as it does straight from the fridge the next day.

Frequently Asked Questions

Can I make caramelized French onion dip ahead of time?

Yes. This dip can be made up to 2 days in advance. In fact, the flavor improves as it chills and the onions have more time to blend into the sour cream.

How long does caramelized French onion dip last?

Stored in an airtight container in the refrigerator, this dip will keep well for up to 4 days.

What should I serve with French onion dip?

This dip pairs well with potato chips, tortilla chips, crackers, pretzels, sliced vegetables, or toasted baguette slices.

Can I speed up the caramelized onions?

You can cook the onions over medium-low heat to speed things up slightly, but cooking them too fast can cause burning instead of caramelization. Low and slow gives the best flavor.

Variations and Substitutions

• Use different onions: Yellow onions work best, but sweet onions can be used for a slightly sweeter dip. White onions will give a sharper onion flavor.
• Add extra herbs: Fresh thyme, dill, or green onions can be added for extra flavor.
• Make it extra tangy: A small squeeze of lemon juice or a splash of apple cider vinegar can brighten the dip if you like a little extra tang.
• Adjust the texture: For a thicker dip, reduce the sour cream slightly. For a looser dip, add a tablespoon or two more.
• Add savory depth: A pinch of smoked paprika or onion powder can add another layer of flavor without overpowering the onions.
• Add jalapeño for heat: For a spicy version, finely dice 1 jalapeño and cook it with the onions until softened. Remove the seeds for mild heat, or leave some in for a spicier dip. Let the mixture cool slightly before mixing it into the sour cream.
