Step-By-Step Instructions
Step 1: Wash and peel the potatoes. Dice into equally sized pieces. This will make sure the potatoes cook evenly. Place potatoes into a large pot and cover with cold water. Add a tablespoon of kosher salt.
Step 2: Cook the potatoes over medium-high heat. Bring the water to a boil. Boil for 10-15 minutes or until potatoes are fork tender.
.
Step 3: Drain the potatoes. Put the cooked potatoes back into the warm pot. This will help evaporate any additional moisture.
Step 4: Add the unsweetened almond milk, salt, and cubed butter. With a potato masher, mash until the potatoes are the consistency you want.
Tips and Tricks
Gently warm the almond milk in a small saucepan or microwave to keep the potatoes from turning cold faster. Do not boil it.
If mashed potatoes look dry, stir in a splash of unsweetened almond milk before reheating.

Ingredient Swaps
- Potatoes - Use a different kind of potato like russets or red potatoes.
- Water - Swap out the water for chicken stock. This will give the potatoes a rich flavor profile.
- Butter - Use a dairy free spread instead of butter.
Variations
- Loaded Mashed Potato Bowls: To create a loaded potato bowl, add chopped-up cooked bacon, gluten free chicken nuggets, shredded cheddar cheese, green onion tops, corn, and dairy free sour cream.
- Sweet Potatoes Mash: Swap in peeled, diced sweet potatoes and Yukon gold potatoes for another option.
Instant Pot Cooking Method
If you have an Instant Pot, don’t snooze on using it for mashed potatoes! It is life-changing.
Step 1: After peeling and dicing potatoes, place them in a steamer basket under the trivet. Cover the potatoes with water, up to the max fill line.
Step 2: Add the cover, make sure the sealing ring is in place, and set to sealing. Cook on high pressure for 8 minutes. Do a quick release of the pressure and drain. Place potatoes back in the pot. Add the milk, butter, and salt. Mash with a potato masher and set the heat to keep warm.
Storing and Reheating
Store: Keep any leftover potatoes in an airtight container in the refrigerator.
Reheat: Reheat leftovers in the microwave, with an additional splash of almond milk or a tablespoon of butter.
Freeze: Leftovers will freeze in a freezer-friendly container for up to four months.
