ingredients for Vegan French Onion Dip measured out against a white surface
  • Cashews: Use raw cashews and make sure they’re soaked overnight for the best results.
  • Yellow onion: This vegan onion dip uses fresh onions instead of an onion soup mix. Feel free to experiment with sweet onions, especially if you prefer a sweeter flavor.
  • Garlic powder: This pantry staple works great and most of the time an ingredient you probably have on hand.
  • Apple cider vinegar: The sweet, tangy flavor is perfect for the dip however, you can also use white vinegar but it will have a slightly sharper flavor.

How To Make French Onion Dip Vegan

  • 1) Soak the cashews. Place the raw cashews in a small bowl and cover with water by about 2-3 inches. Place in the refrigerator to soak overnight. 

HINT: If short on time, simply cover cashews with boiling water and let them soak as long as possible. The ideal soak time is 8 hours, the minimum is 2 hours.

  • 2) Drain the cashews and rinse them with cool fresh water in a colander. Let them drain and set aside.
  • 3) Heat the oil in a medium skillet and add the onion. Cook on low heat, covered for 15 minutes, then remove the lid and cook an additional 5 minutes until golden brown.

  • 4) Combine all the ingredients in a food processor and process for 3 to 4 minutes on high until rich and creamy. Add more water to reach desired consistency and scrape down the sides as needed. Chill in the refrigerator for 1 to 2 hours before serving.

FAQs

Is french onion dip vegan?

The traditional recipe isn’t vegan as it’s made with some combination of dairy-based sour cream, milk, and/or mayonnaise. But, it’s easy enough to make the dip vegan by swapping out the non-vegan ingredients with vegan alternatives. My recipe uses blended, soaked cashews to give the vegan version the perfect amount of creaminess.

How long does this onion dip last in the refrigerator?

If you are storing this homemade onion dip, it is likely missing all the preservatives found in the storebought brands so it will last significantly less time. For best results, store it in an airtight container or jar for up to one week.

Expert Tips 

  • Adjust the seasonings. Feel free to tweak the salt, sweetener, and vinegar as you see fit. You can even double the onion amount if you're an onion fan like I am.
  • No time to chill? It’s ok - you can serve it immediately but the flavors do meld together more over time.
  • Forget to soak the cashews? You can use a quick method and pour hot water over them. Let them sit as long as possible but 1-2 hours minimum is required. The recipe will still work, you may just lose a little creaminess.
