Our Instant Pot skyr recipe makes it easy to make skyr at home. Instead of the two step process of activating the starter, or the old fashioned method of wrapping the pot up in towels, we went with the Instant Pot method. The Instant Pot has one setting for scalding the milk, then another one for culturing it, and they both worked perfectly.
SKYR
Skyr is a traditional Icelandic dairy product that has been part of the country’s culinary culture for centuries. It is a soft cheese-like product made from cultured skim milk, and its texture and taste are somewhere between Greek yogurt and cream cheese. Skyr is packed with a wide range of nutrients and contains a high amount of protein, making it a popular choice for people who are looking to increase their protein intake in a healthy and natural way. It is incredibly versatile, making it the perfect addition to smoothies, oatmeal, pancakes, or even just as a snack on its own.
The history of skyr dates back to Viking and Medieval times in Iceland. It has been mentioned in several medieval Icelandic manuscripts, including the 11th-century Icelandic Landnámabók and the 14th-century Icelandic Flateyjarbók. Skyr was traditionally produced by straining the whey from one day’s run of sour milk into the next; this process gave it its characteristic thick, creamy texture. Today, many Icelandic families still make their own skyr at home using traditional methods, although it can also be purchased commercially in supermarkets. Skyr has become an important part of Iceland’s cultural identity and is widely popular throughout the country, served in homes and restaurants alike.
HOMEMADE SKYR
Skyr is made by adding a specific starter culture to skim milk and then keeping the milk at a particular temperature for about 24 hours, adding rennet and then straining the culture to thicken it.
We make homemade skyr so we can choose exactly what is in it. We use Horizon nonfat milk, since it is traditionally made with nonfat milk and not whole milk. Horizon milk is high quality and organic, and we think it tastes better, and the company is working to fight climate change. The culture is a real skyr starter culture from Cultures for Health, and the rennet that came with it. The starter culture comes in powdered form in tiny packets along with rennet tablets. It conveniently stores for months in the refrigerator. That’s it, no sugar or additives, no preservatives or other things we can’t pronounce.
MESOPHILIC CULTURE
There are a variety of different cultures for culturing dairy products. They can be grouped into two categories – mesophilic and thermophilic. It is important to know what category your starter culture is in, because they thrive at different temperatures.
Skyr is a mesophilic culture, which translates to “medium-loving”. This indicates that it thrives at medium temperatures (around 68-100 degrees F) and is destroyed at a higher temperature (around 113 degrees F). We use an Instant Pot, which makes this really easy, because it holds the proper temperature for hours. The Instant Pot Ultra has a yogurt setting that can be adjusted to low, where it will maintain a constant temperature of 91 degrees F. This works perfectly for making skyr.
MAKING SKYR IN AN INSTANT POT
Because this is a cultured product, it is important that everything is clean. Start with milk that is not near its expiration date. Remove the sealing ring on the Instant Pot lid and thoroughly wash the inner pot, the lid and the ring with very hot water.
Scald the milk, by bringing the temperature on the milk to 181 degrees F. This will kill any unwanted bacteria, and also help produce a thicker yogurt. The Instant Pot Ultra has a yogurt setting that can be adjusted to high. The high setting will scald the milk long enough to kill unwanted bacteria and produce a thicker yogurt.
The milk must then be cooled to below 91 degrees F before adding the skyr starter culture and rennet. Setting the pot in a bowl of ice will cool it much faster.
After adding the starter and rennet, the Instant Pot is then set to the yogurt setting on low and this will keep the mixture at 91 degrees. After 24 hours the milk will separate from the whey, indicating that the skyr is ready to be strained.
Straining the skyr through a fine mesh strainer or cheese cloth will give you a product that is similar to cream cheese. The skyr is then whipped to make it light and airy, a cross between cream cheese and whipped cream.
It is possible to make successive batches of skyr from a few tablespoons of a previous batch, but we usually start with fresh starter culture to make sure the culture is strong and the milk is kept clean.
Helpful tip: Before starting to make a batch, figure out what time it will be ready, so it isn’t ready at an inconvenient time – and remember to add the time it will take to scald and cool the milk.

Ingredients
- 1 quart Horizon milk Nonfat (1-4 quarts)
- 1 package Skyr starter culture and rennet from Cultures for Health
Instructions
Remove the sealing ring and thoroughly wash the sealing ring, inner pot and the lid with very hot water, and put the sealing ring back on. This is a cultured product so it is important that everything is clean.
Add 1-4 quarts of milk to the inner pot of the Instant Pot.
Place the lid on the Instant Pot and lock. Check that the valve is in the sealed position. Select the "yogurt" setting and adjust it to “high” where the display reads "Boil". When the program has finished press cancel until it reads off.
Release the valve, open the pot and remove the inner pot.
Cover the pot with plastic wrap and allow the temperature of the milk to drop. Allow the temperature to drop to 91 degrees F before adding the starter culture. This could take a while, but you could place the bowl on ice to speed it up.
Remove the plastic wrap, add the starter culture and whisk it in for a few seconds. Crush a tablet of rennet and add it to the milk and starter culture, and whisk it in for a few seconds.
Return the inner pot to the Instant Pot. Place the lid on the Instant Pot and lock. The valve can be in either the sealed or unsealed position. Select the "yogurt" setting. The skyr starter culture is mesophilic, so change the setting to “low” and the time to 24 hours and push start.
Check the thickness of the skyr a few hours before the time when it’s supposed to be ready, since the time required can vary. When it has thickened and pulls away from the side of the bowl, transfer it to a fine mesh strainer over a bowl to remove the water (whey).
Once it is the desired thickness, whip it until smooth.
Traditionally served with berries or jam.
It can be stored for 2-3 weeks.
