How to Make Homemade French Onion Dip

  1. Slice and prep the onions

    Peel the onions, then cut them in half from root to tip.

    Lay each half flat and slice into thin half-moons, about 1/8 to 1/4 inch thick.

    Thinner slices caramelize more evenly and melt better into the creamy dip.

  2. Caramelize the onions low and slow

    Heat the butter and olive oil in a large skillet over medium heat.

    Add the sliced onions and 1/4 teaspoon salt, then stir to coat everything in the fat.

    Cook, stirring every few minutes, until the onions turn deep golden and jammy, about 30 to 40 minutes.

    Lower the heat if the onions start to scorch, and add a splash of water to loosen browned bits.

    Remove from the heat and let the onions cool to room temperature.

  3. Mix the creamy dip base

    In a medium bowl, add the sour cream, softened cream cheese, and mayonnaise.

    Beat with a whisk or hand mixer until completely smooth and fluffy, with no visible cream cheese lumps.

    Stir in the garlic powder, onion powder, black pepper, and a small pinch of salt.

  4. Fold in the caramelized onions

    Once the onions are cool, finely chop them for a smoother dip texture.

    Scrape all the onions and any pan juices into the creamy base.

    Fold gently with a spatula until the onions are evenly dispersed, then taste and adjust salt if needed.

  5. Chill to develop flavor

    Cover the bowl tightly and refrigerate for at least 1 hour before serving.

    For the best flavor, let the dip chill 4 to 24 hours so the onions can fully infuse.

  6. Garnish and serve

    Transfer the dip to a serving bowl and smooth the top with a spoon.

    Sprinkle with chopped fresh chives and a little extra black pepper, if you like.

    Serve chilled with potato chips, pretzels, crackers, or crisp raw vegetables for dipping.

Substitutions

Use Greek yogurt instead of some or all of the sour cream
Plain full-fat Greek yogurt adds tang and protein while still keeping the dip rich, creamy, and scoopable.
Use Neufchatel instead of regular cream cheese
Neufchatel has slightly less fat than regular cream cheese, so the dip tastes a bit lighter but still feels indulgent.
Use sweet onions instead of yellow onions
Sweet onions like Vidalia caramelize into a gentler, candy-like flavor that makes the dip taste a little sweeter and mellow.

Tips

Slice onions evenly for even caramelizing
Try to keep the onion slices the same thickness so they cook at the same rate. This prevents some pieces burning while others stay pale.
Do not rush the caramelizing step
True caramelized onions take time over medium-low heat. If they brown in ten minutes, the heat is too high.
Balance the salt at the end
The dip tastes saltier after chilling, so season lightly at first. Add a pinch just before serving, if needed.
Use room-temperature dairy for easy mixing
Let the cream cheese sit out 20 to 30 minutes before mixing. Cold cream cheese clumps and makes the dip grainy.
Make the dip ahead for parties
This dip actually improves after a day in the fridge. Make it the night before and stir once more before serving.

FAQ

Why are my onions burning instead of slowly caramelizing?
Your heat is probably too high, or the pan is too dry. Lower the heat and add small splashes of water as needed.
Can I use dried minced onion instead of fresh onions?
You will not get the same deep, sweet flavor or texture. Dried onion works in a pinch, but fresh caramelized onions taste richer.
How can I fix dip that turned out too thick?
Whisk in a tablespoon of milk, buttermilk, or cream at a time until it loosens. Add more salt only after thinning.
How long does homemade French onion dip keep in the fridge?
Stored in an airtight container, the dip keeps 3 to 4 days. Stir before serving, and discard if it smells off.
Can I make this dip gluten-free?
Yes, the dip ingredients are naturally gluten-free. Just serve with gluten-free chips, crackers, or vegetables instead of wheat-based snacks.

Serving Suggestions

This rich, tangy dip loves salty kettle chips, ridged potato chips, and crunchy vegetables on a big snack board.

For a bistro-style twist, serve it with warm toasted baguette slices and a simple green salad on the side.

Leftover dip also makes an amazing spread for burgers or roast beef sandwiches, adding instant savory onion flavor.
