5-Minute Vegan Sour Cream
This vegan sour cream takes 5 minutes and a blender. It is tangy, creamy, and holds its own on tacos, baked potatoes, or a bowl of chili.
Made with raw cashews, fresh lemon juice, and a touch of apple cider vinegar, it has that real cultured sharpness without any dairy. No one will guess it was this quick.
What Makes This Vegan Sour Cream So Good
Most dairy-free sour creams lean on tofu or coconut and miss the tangy note completely. This version gets its zip from a double hit of acidity: fresh lemon juice plus a splash of apple cider vinegar. Together they mimic the lactic bite of the real thing better than either one alone.
The cashew base gives it a neutral, rich mouthfeel that does not compete with whatever you spoon it onto. It stays thick and scoopable straight from the fridge, and it never splits when you stir it into hot soup or chili.
I keep a jar in the fridge most weeks because it is faster than a trip to the store, and a lot more affordable than the store-bought vegan brands.
Ingredients
- 1 cup raw cashews: unroasted and unsalted, for the cleanest dairy-free flavor
- 2 tbsp fresh lemon juice: more to taste
- 1 tsp apple cider vinegar: adds a second layer of tang without tasting vinegary
- ½ tsp fine sea salt
- ¼ cup cold water: more for thinning
Variations / Substitutions
- Nut-free: Replace the cashews with 1 cup silken tofu, and reduce the water to 2 tablespoons. The texture will be slightly lighter but just as creamy.
- Extra garlicky: Add a small clove of fresh garlic or ¼ teaspoon garlic powder when blending for a garlic cream.
- Spicy chipotle: Blend in 1 chipotle pepper from a can of chipotles in adobo sauce for a smoky, spicy version.
- Herb-flecked: Stir in 2 tablespoons of finely chopped fresh chives or dill after blending.
Try it on a batch of crispy black bean tacos.
How to Make Vegan Sour Cream
Step 1: Soak the Cashews
If you are not using a high-speed blender, pour boiling water over the 1 cup raw cashews and let them sit for 10 minutes. Drain and rinse well. This softens them just enough to blend completely smooth. If you have a powerful blender, you can skip this step and blend the dry cashews with the full ¼ cup water right away.
Step 2: Blend the Sour Cream
Combine the soaked and drained cashews, 2 tablespoons lemon juice, 1 teaspoon apple cider vinegar, ½ teaspoon salt, and ¼ cup cold water in the blender. Blend on high for 60 to 90 seconds, stopping once or twice to scrape down the sides, until the mixture is silky and no graininess remains. If it seems too thick, drizzle in more water a tablespoon at a time until it reaches a soft, scoopable consistency.
Step 3: Swirl and Serve
Spoon the sour cream into a serving bowl and give the top a quick swirl with the back of a spoon. Taste it. If you want a sharper tang, stir in an extra half teaspoon of vinegar or lemon juice. Serve right away or cover and chill for 20 minutes to let the flavors settle and thicken a bit more. It will firm up in the fridge, and the lemon and vinegar notes will mellow as it sits.
A Few Notes Before You Start
- Soaking cashews in hot water is the quickest route to a smooth blend without a long wait. If you forget, you can blend longer, but you might end up with a slightly gritty texture.
- For a thinner, drizzly consistency that is great on salads or grain bowls, add 2 to 3 more tablespoons of water and blend again.
- The tang softens after a day in the fridge. If you are making it ahead, taste it right before serving and add a little more lemon juice or vinegar if you want that sharp punch back.
- Always use raw cashews, not roasted and salted ones. Roasted cashews will make it taste like nut butter, not sour cream.
- This recipe doubles easily, just increase all ingredients proportionally and use a larger blender if needed.
Storing Leftover Vegan Sour Cream
Keep it in an airtight container in the refrigerator for up to 5 days. It will thicken as it chills, so give it a quick stir before spooning it out. Freezing is not recommended, as the texture can turn watery and grainy once thawed.
Frequently Asked Questions
Can I make this nut-free?
Yes. Use 1 cup of silken tofu instead of cashews, reduce the water to about 2 tablespoons, and blend until smooth. The result will be slightly lighter but still creamy and tangy.
Why is my sour cream not tangy enough?
Some lemons are less acidic than others. Try adding an extra teaspoon of apple cider vinegar or a pinch of citric acid until the brightness matches what you want.
Can I use lime juice instead of lemon?
You can, but the flavor will change. Lime gives a brighter, more tropical tartness that works well with Mexican dishes, but it will not taste exactly like traditional sour cream.
My blender struggles to get it smooth. What can I do?
Soak the cashews for longer, at least 4 hours in cool water, or use boiling water and soak for 30 minutes. If small bits remain after blending, you can press the mixture through a fine mesh sieve to remove them.
