In my opinion, potatoes should be a nutritional food group all their own. I love them just about any way they can be made–boiled, baked, steamed, grilled, mashed, air-fried potatoes, sauteed, cooked in a fire pit, and any other way you can think of.

With a rich mixture of mashed potatoes, homemade vegan mayonnaise, and gooey vegan cheese sauce, these dairy-free mashed potatoes are an extra special side dish for any meal or holiday.

How to make cheesy mashed potatoes

There are actually two parts to this recipe–mashed potatoes and cheese sauce. Both are excellent on their own and, when you bring them together, it’s magical!

I like to begin with the cheese sauce. Normally, I have some of this already on hand because we use it with so many other dishes. If I don’t happen to have some in the refrigerator, there’s likely some in my freezer.

Making the cheese sauce is as simple as boiling a pot of potatoes, onions, and carrots, adding them to a blender with spices, and blending until smooth. Set it to the side until it’s time to add it to these mashed potatoes.

I have a Vitamix blender and love to use it to make this cheese sauce as well as other recipes healthy salad dressings, sauces, oil-free hummus, and smoothie bowls.

The recipe card at the bottom of the page has the full list of ingredients with measurements and instructions.

The cheese sauce recipe will make just under a quart, which is more than you will need for this casserole. You’ll find that the leftovers are terrific on pizza, nachos, baked potatoes, and so much more.

Next, start work on the mashed potatoes by washing and then peeling and dicing the potatoes and garlic cloves.

I am often asked which knives I use personally, and I have to say that it is Victorinox. They are the same company that makes Swiss Army Knives and the quality is excellent.

Some folks peel their potatoes, but I like to keep the skins on my potatoes for the nutritional benefits of extra fiber and nutrients.

Place the prepped potatoes and garlic in a large saucepan. Add enough water to cover the potatoes and bring the pot to a simmer over medium heat. Once boiling, reduce heat to low, cover, and cook for about 20 minutes, until potatoes are tender.

When they are ready, remove the potatoes from the heat and drain all the water by placing them in a colander.

Place the potatoes in a large bowl with all the other ingredients (except the cheese sauce)homemade vegan mayo, plant milk, and spices. You’ll want a bowl big enough for mixing easily. Sometimes I even just put them back in the big stock pot I cooked them in to save on cleanup with dishwashing.

Next, mash the potatoes up with a hand mixer or potato masher. I personally love to use a hand mixer to get them nice and creamy. It’s also called the lazy girl way because a potato masher takes so much more work.

Taste and adjust any ingredients to get them to your preferred tastes. Usually salt and mayo make a big difference as you are tweaking this recipe to get it right.

Lastly, add 3/4 cup of the vegan cheese sauce and mix well. Drizzle the final 1/4 cup of the sauce over the top of the potatoes.

Serve as a side with my Vegan Meatloaf. Talk about comfort food, and these are perfect for holiday dinners!

Tips and substitutions

  • Potatoes- I’ve used a lot of different types of potatoes for making these mashed potatoes including Russet, red, and yellow. Whatever you have on hand should be just fine.
  • Cook time- Don’t overcook the potatoes, so the finished product will not be mushy.
  • Plant Milk- I personally love to make these with plain almond milk because it’s my go-to for all my recipes. It makes terrific dairy-free mashed potatoes.
  • Secret ingredient- Most definitely don’t leave out the homemade eggless mayo. It’s a key ingredient.
  • Seasoning- Adjust the salt to your taste preference, as it can make a huge difference in flavor for this dish.
  • Holiday side dish- These mashed potatoes are perfect for Thanksgiving and other holidays.

Prep: 30 minutes
Cook: 30 minutes
Total: 1 hour
Servings: 4 servings

Ingredients 

Mashed Potatoes

Cheese Sauce

  • 1 cup potatoes peeled & diced
  • 1/4 cup carrots diced
  • 1/4 cup onion chopped
  • 1 cup broth from veggies
  • 1/2 cup raw cashews (or 1/2 c white beans)
  • 4 tablespoons nutritional yeast flakes
  • 1 tablespoon lemon juice
  • 1 teaspoon salt
  • 1/2 teaspoon garlic powder
  • 1 pinch paprika
  • 1 pinch cayenne pepper optional

Instructions

Garlic Mashed Potatoes

  • Wash and dice potatoes and peel garlic.
  • Place potatoes and garlic in a large saucepan. Add enough water to cover potatoes and bring the pot to a simmer over medium heat. Once boiling, reduce heat to low, cover, and cook about 20 minutes, until potatoes are tender.
  • When they are ready, remove the potatoes from heat and drain all the water out by placing them in a colander.
  • Place the potatoes in a large bowl with all the other ingredients (except the cheese sauce)–mayo, plant milk, and spices. You’ll want a bowl big enough for mixing well. Sometimes I even just put them back in the big stock pot I cooked them in to save on clean up with dishwashing.
  • Next, mash the potatoes up with a hand mixer or potato masher. I personally love to use a hand mixer to get them nice and creamy. It’s also called the lazy girl way out because a potato masher takes so much more work.
  • Taste and adjust any ingredients to get them to your preferred tastes. Usually salt and mayo make a big difference as you are tweaking this recipe to get it right.
  • Lastly, add in 3/4 cup of the Cheese Sauce and mix well. Drizzle the final 1/4 cup of the sauce over the top of the potatoes.
  • Serve as a side with my Vegan Meatloaf. Talk about comfort food, and these are perfect for holiday dinners!

Cheese Sauce

  • 1. In a medium pot, bring about 3 cups of water to a boil. Place potatoes, carrots, and onion in the pot and allow to cook until veggies are tender–approximately 15 minutes. Cooking time will vary based on how small the veggies are diced.
  • 2. When veggies are tender, drain and place them in a blender. NOTE: reserve 1 cup of the broth, and add to blender. Add all the remaining ingredients, and blend until smooth.
  • 3. I have a Vitamix blender and so don't take the time to soak my cashews. That thing is powerful and everything that goes into it comes out creamy. However, if your blender isn't jet engine speed, soaking the cashews in warm water for at least 30-minutes before adding to this recipe will help this recipe come out more creamy. 
  • 4. Now, it's ready to use in nacho cheese dip, mac-n-cheese, topping for steamed broccoli, or anything else you need a creamy, cheesy sauce in. It makes approximately 1 quart and can be stored in the refrigerator for up to 2 weeks.

  1. Thank you, this turned out well. I had a quick dinner with these mashed potatoes and sauce. To turn it into a complete meal, I added carrots ( I cooked extra) and black beans. Very yummy. I used to love mashed potatoes but had not eaten much lately because I used to love adding butter for the flavour. Fortunately I had some home made vegan mayo and thought I’d give it a go. I will certainly make them again like this!
