This isn’t just the BEST VEGAN ONION DIP I’ve ever had, it’s the best Onion Dip period! And way better than anything store-bought by a million miles!

I haven’t made a Vegan Onion Dip since going vegan, but this blows away whatever I made in the past. Granted, I don’t think I really knew how to cook the last time I made this, but still, this one is way better haha!

It’s super rich and decadent thanks to the caramelized onions and sour cream, cream cheese and mayo. The fresh herbs and seasonings add a bunch of supporting flavor as well. It’s honestly super hard to not just got hog wild on this dip and eat it all in one sitting like a goblin!

And the good news is, this is really easy to make! I will admit, yes the onions do take some time, but they are worth it. Aside from that, it’s just simply mixing everything together.

I will say, the hardest part after waiting for the onions to cook, is waiting for this to hang out in the fridge. I really do recommend letting it rest in the fridge at least 4 hours, if not overnight. The flavors get so much richer and the texture will be nice and firm. Nothing worse than a runny Onion Dip!

ingredients for vegan onion dip

Caramelized Onions – I’m not gonna lie, it takes a while to grill the onions properly. But, it’s totally worth it in my opinion! Plus it’s pretty easy, and you can read a book or something while you do it. All it really involves is stirring the onions around, making sure they aren’t getting burned, and really, that’s about it.

Recently I’ve been finishing my onions with some balsamic vinegar and vegan beef broth. I find this just adds an extra level of umami flavor and it’s relatively easy to do! Just add at once they are just about done and then reduce the liquid. That’s it!

Cream Cheese, Sour Cream & Mayo – You can use store-bought versions for all of these, or you can make some homemade Vegan Cream Cheese and Vegan Mayo. I’ll leave a homemade option for vegan sour cream in the recipe!

Also feel free to play around with the ratios. You can also use unsweetened vegan yogurt instead of mayo. I would recommend using the cream cheese for sure though. This will help the dip get nice and firm in the fridge.

Fresh Herbs & Seasonings – I like to include some parsley and chives. Nutritional yeast makes a cameo along with a few other seasonings!

It’s quite simple, though it does take a little time to caramelize some onions. You can also just grill them really nice, though the dip won’t be as complex in flavor.

Once the onions are done, you simply need to mix everything up.

Then let it rest in the fridge for at least 4 hours, but overnight is best.

Also, this is a great spread for burgers too! Crush up some potato chips on top for something crunchy!


Store in the fridge for up to 3 days. It might last longer than that, but I ate all my test batches within 3 days since it was so dang good!

  • 2 Tbsp vegan butter
  • 2 Tbsp neutral oil
  • Salt to taste
  • Sugar to taste
  • 1 Tbsp Balsamic vinegar (optional)
  • 1/4 - 1/2 cup vegan beef broth (optional)

  • 1 - 2 tsp vegan lactic acid
  • 1/2 - 1 tsp salt
  • 1/2 cup unsweetened plant milk
  • 1 Tbsp lime juice


Caramelized Onions

  1. The most time consuming part of this is grilling the onions, so let's start that before anything else. Add the vegan butter and oil to a pan over medium / medium high heat. Once melted and bubbling, add your onions and stir to coat. Stir it frequently, and after 10 minutes, add in a pinch of salt and sugar, which will help with the flavor and browning.
  2. Keep an eye on the onions and make sure they don't brown too fast, or even worse, burn! Lower the heat as needed, stir frequently, and deglaze with some water if they stick to the pan. They should be perfect in about 45 minutes to 1 hour.
  3. Optionally, you can add 1 Tbsp of balsamic vinegar and 1/4 - 1/2 cup of vegan beef broth. Then just cook them down and reduce the broth. This will add some extra beefy flavor! Once they are done, remove from the heat and reserve. You should end up with about 3/4 cup of caramelized onions, if not more.


  1. Soak the cashews in boiling water for 10 - 15 minutes. Then add them and everything else to a high speed blender and blend until smooth. Store in the refrigerator for 3-5 days. If it thickens too much in the fridge you can add a couple tablespoons of plant milk until it's at your desired consistency.

  1. Start with about 3/4 cup of caramelized onions and add everything else to a bowl and mix and combine thoroughly. Taste and adjust for seasoning, add more of the onions or any other seasoning. You can also add more sour cream, mayo or cream cheese if you like. Refrigerate for at least 4 hours, but overnight is ideal. Garnish with chopped chives, and serve with you favorite potato chips and enjoy!

I also made a version of this where I added about 1/2 cup more sour cream and doubled the cream cheese and it was super delicious. So feel free to add a bit more of those if you like!
