🥔 What to Serve With French Onion Dip

This creamy dip goes perfectly with:

Potato chips
Tortilla chips
Crackers
Pretzels
Carrot sticks
Celery
Cucumber slices
Bell peppers
Toasted bread

For a cookout, put the dip in the center of a large platter and arrange different vegetables and chips around it.

⭐ Why Chilling Is Important

Don’t skip the refrigeration step.

The dry onion pieces need time to soften and release their flavor into the sour cream and mayonnaise. Letting the dip rest in the refrigerator also gives the flavors time to blend together.

For the best flavor, you can even prepare it a few hours before serving.

🧅 Easy Variations

The classic three-ingredient version is delicious on its own, but you can customize it if you want.

Add Fresh Herbs

Mix in a little chopped fresh chives or parsley before serving.

Add Black Pepper

A small amount of freshly ground black pepper adds extra flavor.

Make It Extra Creamy

Use full-fat sour cream and mayonnaise for a thicker, richer texture.

💡 Tips for the Best Dip

Use full-fat ingredients: They generally give the dip a thicker, creamier texture.

Let it rest: Give the dip at least an hour in the refrigerator before serving.

Make it ahead: This is an excellent make-ahead appetizer for parties and cookouts.

Don’t add extra salt immediately: French onion soup mix is already seasoned, so taste the finished dip before adding anything else.

🧊 How to Store It

Keep the dip covered in the refrigerator.

For food safety and quality, don’t leave dairy-based dip sitting at room temperature for extended periods during a party. Put out a smaller portion and replenish it from the refrigerator as needed.
