Have you ever stood in the dairy aisle, staring at the endless rows of yogurt, wondering if you could make something better—tastier, healthier, and without all the added sugar—right in your own kitchen? Making yogurt at home can sound intimidating, like a science experiment best left to the pros. But what if I told you that you might already own one of the best tools for the job? Let’s dive into the magic question: What Is An Instant Pot Yogurt Function, and how can this single button transform your multi-cooker into a personal yogurt factory?
The journey from store-bought to homemade is one of the most rewarding culinary adventures you can take. I remember my first successful batch; the taste was so fresh and tangy, it completely changed my perspective. The Instant Pot takes this already amazing process and makes it virtually foolproof. So, grab a cup of coffee, and let’s demystify this incredible feature together.

Why Use an Instant Pot Instead of a Traditional Yogurt Maker?
Before we get into the nitty-gritty, you might be wondering, “Why not just buy a dedicated yogurt maker?” It’s a fair question! A traditional yogurt maker is a fantastic, single-purpose appliance that does its one job very well. However, the Instant Pot brings a few game-changing advantages to the table.
Think of a dedicated yogurt maker as a reliable sedan—it gets you from point A to point B. The Instant Pot, on the other hand, is like an all-terrain SUV. The Instant Pot yogurt function is just one of its many capabilities. It’s a space-saver, a money-saver, and a master of multitasking. You can sauté, pressure cook, slow cook, and, yes, incubate perfect yogurt all in one pot. This is especially great for those of us with limited counter space!
How Does the Instant Pot Yogurt Function Actually Work?
This is where the magic happens. The Instant Pot yogurt function simplifies the two critical stages of yogurt making: pasteurization and incubation. It provides a controlled, consistent environment that yogurt cultures love.
The function essentially turns your high-tech pressure cooker into a gentle, precise incubator. It maintains a specific, low temperature for an extended period, allowing the live bacteria (the “good guys”) in your starter culture to do their work. They consume the lactose in the milk and convert it into lactic acid. This process is what thickens the milk and gives yogurt its signature tangy flavor.
The Two-Phase Process
- Pasteurizing (The ‘Boil’ Setting): Most yogurt recipes start by heating the milk to about 180°F (82°C). The Instant Pot’s yogurt function has a “Boil” setting that does this for you. This step is crucial because it kills off any competing bacteria in the milk and denatures the whey proteins, which helps create a thicker, more stable yogurt.
- Incubating (The ‘Yogurt’ Setting): After heating, you cool the milk down and add your starter culture. Then, you place the pot back in the Instant Pot and use the regular “Yogurt” setting. This holds the milk at a cozy temperature—typically between 105-115°F (40-46°C)—for several hours. This is the incubation period where the fermentation happens.
A Step-by-Step Guide to the Instant Pot Yogurt Function
Ready to make your first batch? It’s easier than you think. There are two popular methods, and I’ll walk you through both.
Method 1: The Traditional “Boil” Method (For the Creamiest Results)
This is the classic method and my personal favorite for achieving a thick, luxurious texture.
- Pour in the Milk: Pour a half-gallon to a full gallon of milk (whole milk works best for beginners) directly into the clean, stainless steel inner pot of your Instant Pot.
- Pasteurize: Secure the lid (you don’t need to seal the vent) and press the “Yogurt” button until the display reads “Boil.” The machine will heat the milk and beep when it’s done.
- Cool it Down: Carefully remove the inner pot. You need to cool the milk to between 105-115°F (40-46°C). You can do this by placing the pot in an ice bath or just letting it sit on the counter, stirring occasionally. A digital thermometer is your best friend here!
- Add Your Starter: Once cooled, whisk in your starter culture. This can be 2 tablespoons of plain, store-bought yogurt with live active cultures or a powdered yogurt starter. Make sure it’s fully dissolved.
- Incubate: Place the inner pot back into the Instant Pot. Close the lid and press the “Yogurt” button again. Adjust the time using the “+” or “-” buttons. For a mild yogurt, start with 8 hours. For a tangier flavor, go for 10-12 hours.
- Chill Out: Once the cycle is complete, the yogurt will still be warm and a bit loose. Carefully remove the pot, cover it (with plastic wrap or a silicone lid), and refrigerate for at least 6-8 hours, or overnight. This chilling step is essential for the yogurt to set and thicken.
Yogurt Maker Guide Pro Tip: Don’t stir or jiggle the yogurt right after incubation! Moving it too much at this stage can disrupt the curd structure and result in a thinner final product. Be gentle until it’s fully chilled.
Method 2: The “Cold Start” or “No-Boil” Method
This is a fantastic shortcut if you’re short on time. It only works with ultra-pasteurized (UHT) milk because it’s already been heated to a very high temperature, eliminating the need for the “Boil” step.
- Combine Ingredients: In your Instant Pot’s inner pot, whisk together one can (14 oz) of sweetened condensed milk, one 5.2 oz container of plain Greek yogurt (as a starter), and about 6-7 cups of ultra-pasteurized milk until smooth.
- Incubate: Place the pot in the Instant Pot, close the lid, and press the “Yogurt” button. Set the time for 8-10 hours.
- Chill: Once done, refrigerate for at least 6-8 hours to set completely.
Pro Tips for Perfect Instant Pot Yogurt, Every Time
After many batches (some great, some… not so great), I’ve learned a few things. Here are my top tips for success:
- Choose Your Milk Wisely: Whole milk will give you the creamiest, thickest yogurt. 2% milk works well too, but skim milk can result in a thinner texture. For a non-dairy option, full-fat canned coconut milk or soy milk are great alternatives, though they may require a thickener like agar-agar.
- Your Starter Matters: Always use a fresh starter. If using store-bought yogurt, check the label for “live and active cultures.” After your first batch, you can save a few tablespoons of your homemade yogurt to use as the starter for the next one!
- Time is Flavor: The longer you incubate, the tangier your yogurt will be. 8 hours is a great starting point for a mild flavor. Experiment to find your perfect tangy-ness level.
- Want Greek Yogurt? It’s simple! After your yogurt is fully chilled, line a colander with a few layers of cheesecloth or a clean nut milk bag. Set it over a large bowl, pour in your yogurt, and let the whey drain out in the refrigerator for 2-4 hours. The longer it drains, the thicker your Greek yogurt will be.
The Benefits of Making Your Own Yogurt at Home
Beyond the sheer fun of it, making your own yogurt with the Instant Pot yogurt function comes with some serious perks.
- Health and Nutrition: You control everything that goes in. No hidden sugars, preservatives, or artificial thickeners. It’s a fantastic source of probiotics, which are essential for gut health.
- Cost-Effective: A gallon of milk is significantly cheaper than buying the equivalent amount of individual yogurt cups. You’ll be surprised at how much you save over time.
- Incredible Flavor: Honestly, nothing beats the fresh, clean taste of homemade yogurt. You can customize the flavor and texture to be exactly how you like it.
As nutritionist Dr. Alisha Ramos notes, “Homemade yogurt is a powerhouse for gut health. By controlling the fermentation time, you can maximize the probiotic count, delivering beneficial bacteria to your digestive system in a way that many commercial products can’t match.”
How to Clean and Maintain Your Instant Pot for Yogurt Making
Cleaning is a breeze. The stainless steel inner pot is dishwasher safe. The most important thing to pay attention to is the silicone sealing ring in the lid. It can absorb odors from savory dishes like chili or curry.
To avoid a “curry-flavored” yogurt, it’s a great idea to have two separate sealing rings: one for savory cooking and one for neutral or sweet recipes like yogurt and cheesecake. They are inexpensive and easy to swap out.
Frequently Asked Questions (FAQ)
1. Can I make Greek yogurt with the Instant Pot yogurt function?
Absolutely! The Instant Pot makes the base yogurt perfectly. To turn it into Greek yogurt, you just need to strain it through cheesecloth or a yogurt strainer after it has been fully chilled to remove some of the whey.
2. Do I have to use the ‘Boil’ setting every time?
No. If you use ultra-pasteurized (UHT) milk, you can skip the “Boil” step and use the “Cold Start” method. However, for any other type of milk (pasteurized, raw, etc.), the “Boil” step is highly recommended for the best texture and safety.
3. My Instant Pot yogurt is too thin. What went wrong?
This is a common issue! The most likely culprits are: not heating the milk long enough (or hot enough) during the boil phase, adding the starter when the milk was still too hot (which kills the cultures), or not incubating for long enough. Also, make sure your yogurt is chilled for at least 6 hours before you decide it’s too thin.
4. What kind of milk is best for Instant Pot yogurt?
For the richest, creamiest yogurt, whole cow’s milk is the gold standard. However, 2% milk, lactose-free milk, and even some non-dairy milks like soy or coconut milk can work well. The higher the fat content, the thicker the result.
5. How long does homemade Instant Pot yogurt last?
Stored in an airtight container in the refrigerator, your delicious homemade yogurt will stay fresh for about 10 to 14 days.
