A Step-by-Step Guide to Making Instant Pot Yogurt
Here’s a detailed guide to making yogurt in your Instant Pot.
Step 1: Preparing the Milk
The first step is preparing the milk. This involves heating the milk to denature the proteins. This process is essential for creating a thicker, creamier yogurt.
Methods for Heating the Milk
There are two primary methods for heating the milk in your Instant Pot: the boil method and the no-boil method.
The boil method involves heating the milk to 180°F (82°C) to denature the proteins. This can be done directly in the Instant Pot using the “Boil” or “Yogurt” setting (if your model has one). The no-boil method relies on ultra-pasteurized milk, which has already been heated to a high temperature and doesn’t require pre-heating.
If using the boil method, carefully monitor the milk as it heats to prevent scorching. Once the milk reaches the desired temperature, allow it to cool down to 110°F (43°C) before proceeding to the next step.
If using the no-boil method, you can skip the heating stage and proceed directly to the cooling phase. This method saves time and effort but requires using ultra-pasteurized milk for optimal results.
Cooling the Milk
After heating (if necessary), the milk must be cooled to a temperature suitable for the yogurt starter cultures to thrive. The ideal temperature range is between 105°F (40°C) and 115°F (46°C). You can use a kitchen thermometer to monitor the temperature. Cooling can be done naturally by allowing the milk to sit at room temperature or by placing the Instant Pot inner pot in an ice bath to expedite the process. Ensure the milk cools to the correct temperature before adding the starter, as excessively high temperatures can kill the bacteria.
Step 2: Adding the Yogurt Starter
Once the milk has cooled to the appropriate temperature, it’s time to add the yogurt starter.
Types of Yogurt Starter
There are two primary types of yogurt starter: store-bought yogurt with live and active cultures and freeze-dried yogurt starter cultures.
Store-bought yogurt should be plain, unflavored, and contain live and active cultures. Check the label to ensure that it contains the necessary bacteria strains for yogurt making. Use about 2 tablespoons of starter for every gallon of milk.
Freeze-dried yogurt starter cultures are available online or in specialty stores. They offer a more consistent and reliable source of bacteria. Follow the instructions on the package for the appropriate amount to use.
Mixing the Starter
Gently whisk the yogurt starter into the cooled milk until it is fully dissolved. Ensure there are no clumps of starter remaining. Proper mixing is crucial for even fermentation.
Step 3: Fermenting the Yogurt
This is where the Instant Pot truly shines.
Setting the Yogurt Function
Place the inner pot containing the milk and starter back into the Instant Pot. Secure the lid, but ensure the venting knob is set to the “Venting” position. This is important for preventing pressure buildup during fermentation.
Select the “Yogurt” function on your Instant Pot. This setting is specifically designed to maintain a consistent temperature for yogurt fermentation. Adjust the fermentation time according to your desired tanginess and texture. A shorter fermentation time (8-10 hours) will result in a milder, sweeter yogurt, while a longer fermentation time (10-12 hours) will yield a tangier, thicker yogurt.
Maintaining a Stable Environment
It’s crucial to avoid disturbing the Instant Pot during the fermentation process. Refrain from opening the lid or moving the appliance, as temperature fluctuations can disrupt the bacterial activity and compromise the yogurt.
Step 4: Chilling and Straining (Optional)
Once the fermentation process is complete, the yogurt will be warm and slightly runny.
Chilling the Yogurt
Remove the inner pot from the Instant Pot and place it in the refrigerator to chill for at least 4 hours. Chilling stops the fermentation process and allows the yogurt to thicken further.
Straining for Greek Yogurt
If you prefer Greek-style yogurt, which is thicker and tangier than regular yogurt, you can strain the yogurt after chilling. Line a colander with several layers of cheesecloth or a yogurt strainer. Pour the chilled yogurt into the lined colander and place it over a bowl to catch the whey. Allow the yogurt to strain in the refrigerator for several hours, or even overnight, until it reaches your desired consistency. The longer it strains, the thicker the yogurt will become.
Step 5: Storing and Enjoying Your Homemade Yogurt
Once the yogurt has reached your desired consistency, transfer it to airtight containers and store it in the refrigerator. Homemade yogurt typically lasts for 1-2 weeks.
Enjoy your homemade yogurt plain, or add your favorite toppings, such as fresh fruit, granola, honey, or nuts. You can also use it as an ingredient in smoothies, dips, or sauces.
Troubleshooting Common Issues
Making Instant Pot yogurt is generally straightforward, but occasionally, issues can arise. Here are some common problems and their solutions:
- Thin Yogurt: Possible causes include insufficient heating of the milk, low-quality starter culture, or insufficient fermentation time. Ensure you are using fresh, high-quality milk, a reliable starter culture, and allow the yogurt to ferment for a longer period.
- Sour Yogurt: Over-fermentation can result in excessively sour yogurt. Reduce the fermentation time in future batches.
- Grainy Texture: This can occur if the milk is overheated or if the starter culture is not properly mixed. Carefully monitor the milk temperature during heating and ensure the starter is fully dissolved.
- No Yogurt Formation: This typically indicates that the starter culture was inactive or that the fermentation temperature was not optimal. Ensure your starter culture is fresh and viable and that the Instant Pot is maintaining a stable temperature.
- Whey Separation: Some whey separation is normal, but excessive separation can indicate over-fermentation or using low-fat milk. Adjust the fermentation time accordingly and consider using whole milk for a richer, creamier texture.

Using whole milk will typically result in a richer, creamier yogurt, while skim milk will produce a lighter, tangier yogurt. Experimenting with different fat percentages allows you to customize the texture and flavor to your preference.
Beyond cow’s milk, you can also use plant-based milks, such as soy, almond, cashew, or coconut milk. However, keep in mind that these alternatives may require adjustments to the recipe and fermentation time, as they have different protein and sugar compositions. You might also need to add a thickening agent, like tapioca starch or agar-agar, to achieve a yogurt-like consistency with some plant-based milks. Success with non-dairy milk depends on the specific milk and starter culture being used.
What type of starter culture is best for Instant Pot yogurt?
The best type of starter culture for Instant Pot yogurt depends on your desired flavor and texture profile. Store-bought yogurt with live and active cultures is a readily available option. Look for plain, unsweetened yogurt with a clear list of cultures, such as Lactobacillus bulgaricus and Streptococcus thermophilus. These are common cultures used in yogurt production and provide a good starting point. Avoid yogurts with added thickeners or stabilizers, as these may interfere with the fermentation process.
Alternatively, you can use freeze-dried yogurt starter cultures, which are specifically formulated for yogurt making. These cultures often contain a wider variety of beneficial bacteria and can produce yogurt with distinct flavor characteristics. Some popular options include Greek yogurt cultures, Bulgarian yogurt cultures, and mesophilic cultures for making yogurt at lower temperatures. Experimenting with different starter cultures allows you to create a variety of yogurt flavors and textures in your Instant Pot.
How long does it take to make yogurt in an Instant Pot?
The total time to make yogurt in an Instant Pot typically ranges from 8 to 24 hours, with the majority of the time dedicated to fermentation. The initial steps, such as heating the milk (if needed) and cooling it down to the optimal temperature for the starter culture, usually take around 30 minutes to an hour. The fermentation process itself is what takes the longest and can vary depending on the type of starter culture, the type of milk, and your desired level of tanginess.
A shorter fermentation time (8-12 hours) will generally result in a milder, sweeter yogurt, while a longer fermentation time (12-24 hours) will produce a tangier, more acidic yogurt. The ideal fermentation time is a matter of personal preference. It’s recommended to start with a shorter fermentation time and taste the yogurt periodically to determine when it has reached your desired level of tanginess. Once fermented, the yogurt needs to be chilled in the refrigerator for at least a few hours to set properly and further develop its flavor.
How do I prevent my Instant Pot yogurt from becoming grainy or separated?
Grainy or separated yogurt can be a common issue when making yogurt in an Instant Pot. Several factors can contribute to this, including overheating the milk, using too much starter culture, or fermenting for too long. To prevent graininess, ensure you do not overheat the milk during the initial heating process. The goal is to heat the milk to around 180°F (82°C) to denature the proteins, but avoid scorching it. Using an accurate thermometer is highly recommended.
To minimize separation (whey separating from the solids), avoid over-fermenting the yogurt. Check the yogurt periodically during fermentation and stop when it reaches your desired tanginess. Also, chilling the yogurt promptly after fermentation helps to set the proteins and reduce whey separation. If you still experience separation, you can strain the yogurt through cheesecloth to remove the excess whey, resulting in a thicker, Greek-style yogurt. Adding a small amount of pectin or gelatin can also help stabilize the yogurt and prevent separation.
What are some troubleshooting tips for making yogurt in an Instant Pot?
One common issue is yogurt that doesn’t thicken properly. This can be due to using a starter culture that is not viable, not heating the milk sufficiently to denature the proteins, or fermenting at a temperature that is too low. Ensure your starter culture is fresh and stored properly. Confirm that the milk reaches at least 180°F (82°C) during the heating step, and verify that your Instant Pot is maintaining a consistent temperature during fermentation. If the yogurt is still thin, try fermenting for a longer period.
Another issue can be yogurt that is too sour or acidic. This is usually caused by over-fermenting. Reduce the fermentation time in future batches to achieve a milder flavor. If you’re using a freeze-dried starter culture, consider trying a different type of culture that produces a less tart yogurt. Finally, ensure your Instant Pot is clean and free of any lingering odors, as these can affect the flavor of the yogurt. A thorough cleaning before each batch is recommended to avoid off-flavors.
