1 tablespoon olive oil

1 tablespoon vegan butter (or regular butter)

1/2 teaspoon salt

1/4 teaspoon black pepper

1/2 teaspoon onion powder

(Tip: You’ll find the full list of ingredients and measurements in the recipe card below.)

Directions

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

Add chopped onions and salt. Cook, stirring often, for 30–40 minutes, until onions are golden and caramelized. If they begin to dry out, add a splash of water.

Once caramelized, remove from heat and let the onions cool.

In a medium bowl, stir together the yogurt, mayonnaise, onion powder, garlic powder, vinegar, and coconut aminos.

Fold in the cooled caramelized onions and mix until well combined.

Taste and adjust seasoning as needed.

Chill in the refrigerator for at least 1 hour to allow flavors to meld.

Serve with chips, crackers, or fresh vegetables.

Variations

Vegan Version: Use dairy-free yogurt and vegan mayo to make this dip fully plant-based.

Spicy Kick: Add a little hot sauce or cayenne pepper to the mix if you like a bit of heat in your dip.

Herb Infusion: Stir in some fresh chopped herbs like parsley, chives, or dill for added freshness and flavor.

Sour Cream Substitute: For a more classic creamy flavor, swap the yogurt with sour cream (or vegan sour cream if preferred).

Storage/Reheating

I recommend storing any leftover dip in an airtight container in the refrigerator for up to 3 days. The flavors tend to deepen and become even more delicious as it sits. There’s no need to reheat this dip; it’s best served cold, straight from the fridge.

FAQs

Can I use yellow onions instead of red onions for this dip?

Yes! Yellow onions are actually the perfect choice for this dip because they caramelize beautifully and bring a sweeter flavor, making them ideal for this creamy onion dip.

Can I substitute the mayonnaise for something else?

Absolutely! If you’re looking for a healthier option, you can swap the mayonnaise for Greek yogurt. If you prefer a different flavor, try using a dairy-free mayonnaise or even cream cheese.

How do I prevent the onions from burning while caramelizing?

To prevent the onions from burning, make sure to cook them over medium heat, and stir them frequently. If they start sticking to the pan or look like they’re drying out, just add a little water to help them soften and continue caramelizing.

How long should I refrigerate the dip before serving?

I recommend refrigerating the dip for at least 1 hour before serving. This allows the flavors to meld together, making the dip even more flavorful.

Can I make this dip ahead of time?

Yes! In fact, this dip tastes even better if made the day before and allowed to chill overnight. Just cover it tightly and store it in the refrigerator.

Conclusion

This creamy French onion dip is an easy-to-make crowd-pleaser that’s perfect for any occasion. The rich, caramelized onions mixed with the tangy yogurt and creamy mayo create a flavor combination that’s irresistible. Whether you’re serving it at a party or enjoying it as a snack, it’s guaranteed to be a hit.
