FAQ

Can I use regular potatoes instead of baking potatoes?

Baking potatoes work best due to their high starch content, but Yukon Gold can work for a creamier texture. Avoid waxy red potatoes as they don't mash well.

How long will these keep in the refrigerator?

Store covered in the refrigerator for up to 3 days. Reheat gently with a splash of almond milk to restore creaminess.

Can I make these ahead for a party?

Yes, make up to 1 day ahead and refrigerate. Reheat in slow cooker on low with extra almond milk, stirring occasionally until heated through.
