Do you love yogurt? Did you know that fresh yogurt with simple, wholesome ingredients is incredibly easy to make at home? This tutorial will walk you through how to make yogurt, Greek yogurt, and Labneh.
Why Learn How to Make Yogurt?
We go through a lot of yogurt in my house.
I use Greek yogurt as a source of protein, we swap out mayonnaise for yogurt in dressings and sauces, and the husband blissfully devours yogurt as a snack.
I’d been happily buying store-bought, plain, whole milk Greek yogurt for several years when I noticed something a little odd.
Different brands of “plain” Greek yogurt had VASTLY different calorie, fat, and sugar contents listed on the nutrition labels.
Yes, even the organic brands varied from one to the other.
Check this for yourself the next time you shop for yogurt.
How could this happen?
Some brands use different recipes for their yogurt, some strain off different amounts of whey, and some brands add chemical thickeners and other ingredients that I’d just prefer not to eat.
As I stood in the grocery store– reading label after label after label– I started to wonder, “How DO you make yogurt? How hard it could be?”
Turns out– it’s not hard.
This guide will walk you through How to Make Yogurt, and then how to strain that yogurt to get Greek yogurt and the even thicker Labneh.
What Is Yogurt?
Yogurt is a creamy, semi-solid fermented milk product that contains live cultures.
It’s made by heating milk, letting it cool back down, and then introducing a starter (pre-made yogurt or freeze-dried cultures) into milk. Next, you let it ferment at a warm temperature for a few hours.
What is Greek Yogurt?
Greek yogurt is yogurt that’s been partially strained. The watery whey drains off the yogurt, leaving you with a thicker, creamy dairy product.
What is Labneh?
Labneh takes Greek yogurt and kicks it up a notch.
It’s a Middle Eastern “cheese”– but really it’s strained yogurt that’s been strained even LONGER than Greek yogurt, until you’re left with an extra creamy, spreadable fermented dairy product.
Traditionally, labneh is strained until you can roll it into balls, and then stored under olive oil.
But, feel free to skip that part unless you want to roll it!
What Kind Of Yogurt Starter Should I Use?
Do you mean that I have to BUY yogurt to MAKE yogurt?!
Yes– yes you do.
BUT– once you’ve got your own yogurt going, you can use your own yogurt as the starter for your next batch.
You can use PLAIN store-bought yogurt, but make sure it says “live probiotic cultures” on the label.
Never use flavored yogurt as a starter.
Make sure you actually like the taste of the yogurt you’re using as a starter, because it will affect the taste of the finished yogurt product.
Another option (and my preference) is to use freeze-dried yogurt starter to get your first batch of yogurt started.
Quick Tip: Sometimes I like to add a little plain kefir milk to my yogurt starter for a richer flavor with more bacterial cultures.
Yogurt Troubleshooting: After several batches of using your own yogurt as a starter, it’s possible that the cultures will start to die off. When that happens, you’ll need to start over.
That’s why I prefer the freeze-dried starter– each package comes with several starters, and I can just keep it on hand.
Do I Need a Yogurt Maker?
No, but if you don’t use a yogurt maker, you definitely need an instant read thermometer.
To make yogurt, you’ll need to hold the milk and yogurt starter mix somewhere between 110°F and 115°F for 4 to 10 hours.
You can do this by keeping your yogurt warm in a heavy, pre-heated Dutch oven, in some slow cookers, or even by storing the container in an insulated travel bag.
BUT– if you choose to use one of these techniques, you’ll need to check the temperature of the yogurt before you start, during, and after the yogurt-making process to make sure that it’s stayed at the right temperature.
My preference is to use a yogurt maker– because they’re cheap, and mine has made my life easier. Iuse a DASH yogurt maker. If you own an Instant Pot, check it– some models include a yogurt maker setting.

What Kind of Milk Should I Use?
Pasteurized or Unpasteurized cow’s milk will work perfectly for your yogurt. Ultra-pasteurized milk is not recommended.
Whole milk will give you the creamiest, richest yogurt. Low-fat milk or non-fat milk will make thinner yogurt, and also seem to give a smaller yield when you strain the yogurt.
What about other animal or non-dairy milks? Check out this resource for alternate or non-dairy milk yogurts.
When I Boil Milk it Burns onto the Pot. Help!
To make yogurt that will thicken, you need to bring your milk to roughly 180°F– you can use a thermometer, but you don’t really need to. Just get the milk to a simmer or soft boil.
Except, when you do this on the stovetop– there’s a problem. The milk will– almost inevitably— burn to the bottom of the pot. Even if you whisk it periodically. (Oh, and sometimes it boils over and into the stovetop drip pan– and that is THE WORST!)
I despise scrubbing burnt milk off of my kitchen pots.
And so, pretty quickly, I started heating my milk up in the microwave. That’s right– in the microwave.
It’s faster. It’s not as messy. And if you misjudge the time, and your milk boils over– that rotating plate is a whole lot easier to clean than burnt milk on a drip pan!
(But– if you’re a microwave hater, you just go right ahead and heat the milk on the stove. That’s perfectly fine too!)
How Do I Strain the Yogurt?
My preference is to use a fine mesh sieve, because it’s easy, reusable, and it’s not messy.
If you prefer, you can strain the yogurt through butter cheesecloth, butter muslin, or multiple layers of regular cheesecloth or muslin.
Leftover whey: The liquid you strain off your yogurt is usable! Check out these ways to use whey.
How to Make Yogurt, Greek Yogurt, or Labneh
Once you’ve gathered all your yogurt-making equipment and ingredients, it’s time to learn how to make yogurt!
Simply bring the milk to a simmer, let it cool down to room temperature, add the starter, and then hold the mixture at a warm temperature for 4 to 10 hours. Then, if you want, strain it until it’s the texture you prefer!
Scoop a little yogurt out to start your next batch, and enjoy!
How to Make Yogurt, Greek Yogurt, and Labneh
- 4 cups milk (whole milk preferred) No ultra-pasteurized milk
- 1/2 cup plain yogurt with live probiotics OR 1 freeze-dried yogurt starter packet
- Bring milk to a simmer or soft boil. (Approximately 180°F.)Tip: Microwave milk for about 9 minutes instead of cooking it on the stovetop for faster cook time and easier clean-up.
- Allow milk to come to room temperature. Pour a small amount of milk in a bowl with the yogurt starter, and whisk until incorporated. Pour the mixture into the main container of milk. Whisk until incorporated.
- Pour milk mixture into the basin of a yogurt maker and hold between 110°F and 115°F for 4 to 10 hours. A short fermentation time will yield a sweet yogurt, and a longer fermentation time will yield a tart yogurt.Tip: If you don’t have a yogurt maker, pour yogurt into a warmed, heavy Dutch oven and store in the oven with the light on. Check the temperature before, during, and after cooking to make sure it stays in the correct temperature range.
- For Yogurt: Serve as is, or use a blender to make it even smoother. (Note: Depending on the strain of yogurt starter used, this yogurt will likely be very thin.)
- For Greek Yogurt: Pour yogurt into an ultra-fine mesh strainer OR line a mesh sieve with cheesecloth, and let it strain in the refrigerator for anywhere from 30 minutes to 2 hours until it's reached the desired consistency.
- For Labneh: Follow directions for Greek yogurt, and continue to strain the yogurt for anywhere from 8 hours to 2 days, until it's reached the desired consistency. Optionally, roll the finished labneh into balls and store in olive oil.
- Serve yogurt, Greek yogurt, or labneh plain, with fruit or other desired toppings, or blend in other ingredients (like fruit or honey) to the finished product.
- Store finished yogurt, Greek yogurt, or labneh in an airtight container in the fridge for up to 2 weeks.For best reculturing results, use 1/2 cup of the finished product to start a new batch of yogurt within 7 days.
Cook time does not include straining the yogurt, and is based on a 4 hour fermentation time. Actual cook time will change depending on how long you ferment and strain the yogurt. Troubleshooting:
- My yogurt didn’t set: Did you add the starter while the yogurt was still hot? It’s possible you killed the bacteria. If the yogurt wasn’t still hot when you added the starter, then it’s possible that the bacteria in your starter were dead. Try again with a new starter.
- My yogurt was lumpy: This one is a quick fix– blend the yogurt with an immersion blender or in a blender basin to make it creamier. To prevent lumpy yogurt, make sure that you whisk well when you add the starter to the milk, until the starter is fully incorporated and any lumps have disappeared. This will help fully incorporate the bacteria.
- Use as a substitute for mayonnaise
- Add to smoothies to add probiotics or as a thickener
- Add toppings like honey, diced fruit, shredded coconut, or melted chocolate
- Blend with fruit for flavored yogurt
- Add any toppings you’d add to yogurt
- Use instead of butter on bread
- Use instead of cream cheese
- Use instead of ricotta in baked pastas
- Drizzle with olive oil and Italian spices
- Drizzle with honey and Italian spices or za’atar herb mixture
