Add chopped potatoes, carrots, onion, and cashews into a saucepan, add water until just covered, and bring to a boil.
Cover, reduce to a simmer, and cook until vegetables are soft (this takes about 10 minutes).
Add cooked veggies and cashews into your blender and add the rest of the ingredients. Blend on high until very smooth. Time will vary depending on the strength of your blender. Be sure to vent your blender to allow steam to escape since the vegetables are hot. I removed the plastic insert in my lid and covered it with a dishtowel.
When done, serve however desired, or store in an airtight container in the fridge.
