As a coconut-free, nut-free, dairy-free AIP milk alternative, sweet potato milk is an easy-to-make, creamy, and tasty beverage that works well for many things.
The internet can definitely be an interesting place. Sometimes you'll find useless information that'll just take up needed space in your brain but sometimes you learn important or useful things!
That happened to me recently when I happened upon an article talking about potato milk. I'd never heard of such a thing, but after reading how to make it I thought to myself “Well, if it worked with sweet potatoes then that would be a PERFECT coconut-free AIP milk alternative!”
So I set about trying it out.
You can see how I did this, plus my reaction to how it tastes in this video, or just skip below to see the screen shots with explanations of each step.
So what DOES this taste like?
Well, if you didn't watch the video, here's the spoiler – it tastes quite sweet potato-y, which I guess is to be expected. I actually thought the taste was a lot better than I anticipated and quite liked it.
I'm not sure if it's one of those things I'd drink just to drink milk, and I don't necessarily think it'd go well with some sweeter dishes, like any of my Tigernut Granolas, for instance. The sweet potato taste I think would just overpower them. For those, I'd rather have Banana Milk.
How to make sweet potato milk
For this you'll just need a sweet potato, some water, and optional maple syrup (if you want it a bit sweeter and you're not on Whole30).
I don't think the size of the potato matters too much – the bigger the potato the creamier and thicker the milk will be.
First you'll peel and chop the potato into 1-inch cubes. Here I'm using a white sweet potato, but a regular orange-fleshed one would work as well (I think a purple-fleshed one would be so much fun!)
Add the sweet potato chunks to a pot and add about 4 cups of water.
Put the pot on the stove and bring to a boil. Boil for approximately 15 minutes, or until the potatoes are soft and easily pierced with a fork.
Using a slotted spoon, transfer the potatoes to a blender, reserving the cooking water.
Pour the reserved cooking water into a measuring cup.
If you do not have 4 cups, add more water to make 4 cups.
Pour the water into the blender.
Add a teaspoon of maple syrup if desired (and not on Whole30).
Blend for 1-3 minutes, or until completely blended and creamy.
Do you need to strain this milk?
If you watch the video you'll see that I went through the process of straining it, but I really don't think it did anything other than add more time to the process. There wasn't much at all left in the nut milk bag I used, so I don't think it's necessary. However if you want to, go for it!
How long does it last?
This milk stays in the fridge well for up to 5 days (it may separate a bit, so shake it before using) or you can freeze it for up to 3 months.
I recommend freezing either in ice cube trays or 1-cup servings in a freezer-safe container or bag. If using the ice cube trays (great for if you need just a small amount for a coffee-like drink), freeze until frozen and then pop out and store in a freezer-safe container or bag. I love these silicone ice cube trays but any will do.

Sweet Potato Milk (Paleo, Whole30, AIP)
- 1 Sweet Potato (use a bigger potato for thicker, creamier milk and a smaller one for less creamy milk)
- 4 cups Water (plus more after cooking if needed to make 4 cups)
- 1 tsp Maple Syrup (optional, omit for Whole30)
- Peel and chop the potato into 1-inch cubes. Add to a pot and add 4 cups of water.
- Bring the pot to a boil over medium high heat and boil for approx 15 minutes, or until the potatoes are soft and easily pierced with a fork.
- Using a slotted spoon, transfer the potatoes to a blender, reserving the cooking water.
- Pour the cooking water into a measuring cup. You'll need 4 cups so if some of the water was absorbed into the potatoes or evaporated during the cooking process, add fresh water to make 4 cups. Add this water to the blender as well.
- This step is optional (and don't do it if you're on Whole30), but you can also add 1 tsp of maple syrup at this time.
- Blend the mixture on high for 1-3 minutes, or until completely blended and creamy. Store in the fridge for up to 5 days or the freezer for up to 3 months.
