The Best Dairy Free Mashed Potatoes

The Best Dairy Free Mashed Potatoes

Plant Based Recipes

This is the second post in our vegan, Thanksgiving sides series. I love mashed potatoes. It’s one of my top comfort foods. There’s really nothing better than eating a warm bowl of mashed potatoes and fried chicken or cauliflower. 

A couple of years ago I discovered tofutti sour cream which rocked my world. Being allergic to dairy, I had never really experienced sour cream. Nachos, sour cream apple pie, burritos, spinach dip, artichoke dip, and of course digging into AMAZING mashed potatoes… Mmmmm.

Unfortunately it comes in a plastic box, covered with plastic film, and it has some questionable ingredients. Hydrogenated soybean oil? It’s main ingredient is water and it’s loaded with sugar. But, now that I’ve tasted the holy grail, there’s no way I’m going back to lame mashed potatoes.

So, I’ve been experimenting with different ways to make non-dairy sour cream. I had a happy accident and made cream cheese! Woo-hoo! But, I finally nailed the sour cream mashed potatoes. It only takes about 15-20 minutes making it a serious Thanksgiving win!  

Vegan Mashed Potatoes

8 servings; 20 minutes

16 Small Red Potatoes (yellow potatoes are fine or four peeled russets)

1 1/3Cup of Cashews

          2 Cups of Starch Liquid

2 Limes Juiced

         1/4 Cup White Vinegar

         2 Teaspoons of Salt

         1 Cup of Good Olive Oil

Fill a large pot with water and bring to a boil. Add chopped potatoes and cashews. The potatoes and cashews should be ready after about 15 minutes. You should be able to easily insert a fork into the potatoes and the cashews should be plump. Place the potatoes in a separate bowl and set aside. Put your cashews, 2 cups of the  starchy potato liquid and all of the other ingredients in a blender or food processor. Blend until smooth 2-3 minutes. Mash your potatoes and fold in your creamy cashew mixture. Add extra salt, pepper, oil, green onions or my personal favorite smoked paprika for a pretty garnish.

    1. Well you don’t blend the potatoes. I hope I made that clear. Eek! You’ll have potato purée. They’re in a separate bowl. You blend everything else and fold it into the mashed potatoes.

  1. You’re a vegan mind reader. We just had mashed potatoes and I was thinking to myself that I totally NEED a great vegan mashed potato recipe! Thanks much. Will try soon.

    1. She will be so thankful!! Several years ago in my PZW days I went to my exbf’s family for the holiday and they didn’t prepare a single thing I could eat. We had been dating three years so they knew I had a dairy allergy. It was the worst. We had to find something drive through for me. This whole month I’m doing dairy free thanksgiving recipes. Thanks for bookmarking! If you’re looking for anything specific let me know and I’ll experiment!

  2. I will have to give this a try. I have to tell you when I saw the title I had a flash back to the m&m Christmas commercial where the m&ms see Santa and one of them says, "He does exist" and faints then Santa says "They do exist" and faints… that’s how I felt… "Dairy free mashed potatoes..they do exist!"
    Thanks for sharing 🙂

  3. When I married, I learned my in-laws’ secret for the most potato-y mashed potatoes I have ever potatoe-d: salt the water when it boils, cook until tender, drain (reserving all the liquid), add a tablespoon of margarine or butter, mash it up, then add the liquid back in to your desired consistency. (We also use any leftover liquid in gravy or stock)
