Gathering Your Supplies and Ingredients
Before you begin, make sure you have everything you need within easy reach. This will streamline the process and prevent any last-minute scrambling.
Essential Equipment
- Instant Pot Duo Plus: Obviously, the star of the show. Ensure it’s clean and in good working order.
- Stainless Steel Inner Pot: This came with your Instant Pot and is crucial for the yogurt making process.
- Thermometer: A reliable food thermometer is essential for verifying the milk has reached the correct temperature during pasteurization.
- Whisk: A whisk is needed to stir the milk and yogurt culture thoroughly.
- Glass Jars: Clean glass jars (like mason jars) are perfect for storing the finished yogurt.
- Ladle: For easily transferring the yogurt into the jars.
Core Ingredients
- Milk: Whole milk generally produces the thickest, creamiest yogurt, but you can use 2% milk, skim milk, or even non-dairy alternatives like almond or soy milk (results may vary). One gallon is a good starting point.
- Yogurt Starter: This is crucial. You have two main options:
- Store-bought plain yogurt: Choose a yogurt with live and active cultures. Look for strains like Lactobacillus bulgaricus and Streptococcus thermophilus on the label. A small amount (2-3 tablespoons) is all you need.
- Yogurt starter culture: You can purchase dried yogurt starter cultures online or at specialty stores. Follow the instructions on the package for activation.
Optional Additions
- Powdered Milk: Adding a few tablespoons of powdered milk to your milk mixture can help thicken the yogurt.
- Sweeteners: Honey, maple syrup, or other sweeteners can be added after the yogurt is finished, or even during the cooling phase (but avoid adding them before fermentation, as they can interfere with the culture).
- Flavorings: Vanilla extract, fruit purees, or extracts can be stirred in after fermentation to customize the flavor.
The Yogurt-Making Process: Step-by-Step
Now that you have your equipment and ingredients ready, let’s get started! Follow these steps carefully for the best results.
Step 1: Pasteurizing the Milk
This step is essential for killing any unwanted bacteria in the milk and creating a clean slate for the yogurt cultures to thrive.
Pour the milk into the Instant Pot’s stainless steel inner pot. Place the pot inside the Instant Pot. Secure the lid. Press the “Yogurt” button. The display will likely show “boil”. If not, press the “Adjust” button until “boil” appears. This initiates the pasteurization process.
The Instant Pot will now heat the milk to approximately 180°F (82°C). Monitor the milk’s temperature using your thermometer. Once it reaches 180°F (82°C), the Instant Pot will beep, signaling the end of the boiling cycle.
If your Instant Pot model does not have a “boil” setting on the yogurt function, you can use the “Saute” function. Be sure to monitor the milk constantly and stir frequently to prevent scorching. Turn off the “Saute” function once the milk reaches 180°F (82°C).
Step 2: Cooling the Milk
After pasteurization, the milk needs to cool down to a temperature suitable for the yogurt cultures, typically around 105-115°F (40-46°C).
Remove the inner pot from the Instant Pot and place it in an ice bath in your sink. Stir the milk occasionally to promote even cooling.
Alternatively, you can let the milk cool at room temperature, but this will take significantly longer.
Use your thermometer to monitor the milk’s temperature. It’s crucial to reach the correct temperature range before adding the yogurt starter.
Step 3: Adding the Yogurt Starter
Once the milk has cooled to 105-115°F (40-46°C), it’s time to add the yogurt starter.
In a small bowl, mix the yogurt starter (either store-bought yogurt or dried starter culture) with a small amount of the cooled milk. This will help to temper the starter and ensure it mixes evenly into the larger batch of milk.
Gently pour the yogurt starter mixture into the inner pot with the cooled milk. Whisk thoroughly to ensure the starter is evenly distributed. This is crucial for proper fermentation.
Step 4: Incubation
This is where the magic happens. The yogurt cultures will now ferment the milk, thickening it and developing that characteristic tangy flavor.
Place the inner pot back into the Instant Pot. Secure the lid. Press the “Yogurt” button again. This time, the display should show the incubation time.
The default incubation time is usually 8 hours, but you can adjust it to your preference. Longer incubation times (up to 12 hours) will result in a tangier yogurt. Shorter incubation times (6-8 hours) will produce a milder yogurt. Use the “Adjust” button to modify the incubation time to your desired length.
Resist the urge to open the Instant Pot during the incubation process. This can disrupt the fermentation and affect the final result.
Step 5: Chilling and Storing
Once the incubation is complete, the yogurt will be warm and slightly thickened.
Remove the inner pot from the Instant Pot and transfer the yogurt to your prepared glass jars.
Place the jars in the refrigerator for at least 4 hours, or preferably overnight. This chilling period will further thicken the yogurt and develop its flavor.
The finished yogurt can be stored in the refrigerator for up to a week.
Troubleshooting Common Yogurt-Making Issues
Even with the ease of the Instant Pot, sometimes things don’t go exactly as planned. Here are some common problems and how to fix them.
Thin or Runny Yogurt
- Insufficient Incubation Time: Extend the incubation time by a few hours in your next batch.
- Low-Fat Milk: Whole milk yields the thickest results. Try using whole milk or adding powdered milk.
- Weak Starter: Ensure your yogurt starter is fresh and contains live and active cultures. Try a different brand or a fresh batch of starter.
- Temperature Fluctuations: Avoid opening the Instant Pot during incubation.
Sour or Bitter Yogurt
- Over-Incubation: Reduce the incubation time in your next batch.

Making yogurt at home with the Instant Pot Duo Plus is a straightforward and rewarding experience. With a little practice and these helpful tips, you’ll be enjoying delicious, creamy homemade yogurt in no time!
What kind of milk works best for Instant Pot yogurt?
Pasteurized milk, whether whole, 2%, or skim, works well for making yogurt in the Instant Pot. Ultra-pasteurized milk also works but may result in a slightly thinner yogurt. Avoid using raw milk due to potential safety concerns and inconsistent results.
For the creamiest and richest yogurt, whole milk is generally preferred. Lower-fat milks, like 2% or skim, will produce yogurt with a thinner consistency. You can experiment with different types of milk to find your preferred taste and texture.
Do I need a special yogurt starter for the Instant Pot?
You do need a yogurt starter, but it doesn’t have to be anything fancy. You can use a plain, unflavored yogurt with live and active cultures from the grocery store as your starter. Look for yogurts that specifically list “live and active cultures” on the label.
Alternatively, you can purchase a dedicated yogurt starter culture online or from specialty stores. These cultures often come in powdered form and can be stored for longer periods. Using a dedicated starter culture may offer more consistent results, especially if you plan to make yogurt regularly.
How long does it take to make yogurt in the Instant Pot Duo Plus?
The active time involved in making yogurt is minimal, usually around 15-20 minutes. This includes heating the milk, cooling it down, and adding the starter. However, the incubation process in the Instant Pot can take anywhere from 8 to 12 hours.
The incubation time depends on the desired tanginess and thickness of the yogurt. Shorter incubation times result in a milder flavor and thinner consistency, while longer times produce a tangier and thicker yogurt. Experiment with different incubation times to find your preference.
Can I use sweeteners or flavorings in my homemade yogurt?
It’s best to add sweeteners and flavorings after the yogurt has finished incubating and chilling. Adding them beforehand can interfere with the culturing process. Stir in your desired sweeteners, such as honey, maple syrup, or sugar, after the yogurt is made.
You can also add flavorings like vanilla extract, fruit purees, or spices such as cinnamon. Consider adding fruit compotes or granola as toppings for a more complete and flavorful yogurt experience. Just remember to add these after the yogurt is prepared.
What if my Instant Pot yogurt is too thin?
Several factors can contribute to thin yogurt. Using ultra-pasteurized milk, not using enough starter, or not incubating for long enough are common causes. If your yogurt is too thin, you can try draining off the whey using cheesecloth or a fine-mesh sieve.
Draining the whey will thicken the yogurt and create a texture similar to Greek yogurt. Line a strainer with cheesecloth, place the yogurt in the strainer, and let it drain in the refrigerator for a few hours until it reaches your desired consistency. Discard or reserve the whey for other uses.
How should I store my homemade Instant Pot yogurt?
Once the yogurt has finished incubating and chilling, transfer it to an airtight container and store it in the refrigerator. Homemade yogurt will typically last for 1 to 2 weeks in the refrigerator. Make sure to use a clean container to prevent contamination.
It’s a good idea to reserve a small amount of your homemade yogurt to use as a starter for your next batch. This ensures you always have a culture available for making more yogurt. Store the starter yogurt separately in a clean, labeled container.
Is it safe to use the “Boil” function on my Instant Pot Duo Plus for the milk?
While you can use the “Boil” function, it’s not always necessary and can sometimes scorch the milk at the bottom of the pot. A safer and more controlled method is to use the “Sauté” function on the “Less” setting. This allows you to gently heat the milk while monitoring it closely.
Regardless of which method you choose, it’s crucial to stir the milk frequently to prevent scorching and ensure even heating. The goal is to heat the milk to 180°F (82°C) to denature the proteins, which helps create a thicker yogurt. Using a thermometer is highly recommended.
