My personal favorite is Yukon gold potatoes (yellow potatoes). It yields the creamiest, best-texture potatoes. You can also use red potatoes, baby potatoes, and fingerling potatoes; these are all waxy potatoes that make for the best vegan potato salad. Waxy potatoes make for a better creamy potato salad because they tend to be more creamy, hold their shape, and overall have less starch in them. Russet potatoes are not the best option for potato salad because they tend to get a bit mushy after cooking.
