Slow cooker yogurt is an easy, healthy and inexpensive way to make homemade yogurt without a yogurt maker. Prepare it in five minutes, go to bed, and wake up to a freshly made breakfast!

How to Make Slow Cooker Yogurt
Yogurt can be expensive and often times it has a long list of artificial colors, flavors, and who knows what else. So here is a super easy recipe to make your own slow cooker yogurt. It is plain yogurt, but you can add honey, jams, fresh fruit, and just about anything else you like. I also use it in place of sour cream in most recipes. This is a great way to to get organic yogurt on the cheap. You can buy a carton of organic milk and turn it into yogurt for about half the price of organic yogurt.
The recipe is so easy that it practically makes itself. You just have to commit a little time to the process! You essentially just use your slow cooker to scald the milk and then the heavy warm crock radiates heat all night long to help culture your new batch of yogurt. The hands-on time is about 5 minutes, though the waiting time is about 15 hours. I like to start this in the afternoon so that it’s ready to sit for its long 8-12 hour warm resting period overnight. We then wake up to fresh yogurt and I’ll serve it with fresh fruit and some homemade granola.
I really recommend straining this yogurt through 3-4 layers of cheese cloth for a few hours too. This helps it to thicken up to a more “Greek yogurt” consistency which my kids prefer (and it’s easier to eat). I explained more of how I do that in the tips and tricks section. Before you know it, you’ll know how to make homemade yogurt with your eyes closed.
Tips and Tricks for making Slow Cooker Yogurt
- I’d highly recommend getting a little instant-read thermometer to make homemade yogurt – it’s all about the temperature! I use this $10 thermometer all the time.
- The goal is to scald the milk which takes place around 180 degrees. So you could check it with a thermometer the first time to see if the “warm” setting is warm enough or if maybe an hour and 45 minutes would work on low. Once you figure it out, I don’t think you would have to use the thermometer every time.
- After the milk is scalded, the waiting time is meant to bring the milk down to around 115-110 degrees so that it’s still warm but won’t kill your yogurt culture!
- You don’t have to buy commercial plain yogurt every time. Just save 1/2 cup of your own yogurt for the starter for the next batch.
- I really recommend straining this yogurt through 3-4 layers of cheese cloth for a few hours, too. This helps it to thicken up to a more “Greek yogurt” consistency which my kids prefer (and it’s easier to eat). I simply set a large colander in a bowl, line it with cheese cloth, and then pour my yogurt in from the slow cooker. I cover it with a clean dish towel and let it sit for a few hours until it’s the consistency that I like. Do note that the yogurt will also thicken some when refrigerated. Play around with it until you figure out how thick or how thin you prefer your yogurt and make notes. That’s the perk of cooking from scratch – you get a product that is truly customized to your preferences.
How long does homemade yogurt last?
Homemade yogurt is generally good for eating for up to 2 weeks when properly stored in the refrigerator.
Do I have to buy store bought yogurt every time in order to make homemade yogurt?
You don’t have to buy commercial plain yogurt every time. Just save 1/2 cup of your own yogurt for the starter for the next batch.
How can I make homemade yogurt thicker:
There’s a few ways to make your yogurt thicker!
- Use whole milk instead of 2% or skim. The higher milk fat lends to a thicker yogurt.
- Stick it in the fridge. Your yogurt with thicken up some as it gets cold.
- Strain your yogurt. By removing some of the whey, you are left with a thicker Greek style yogurt.
- I strain my yogurt 2 ways, one is by straining the yogurt through 3-4 layers of cheese cloth for a few hours, too. Simply set a large colander in a bowl, line it with cheese cloth, and then pour yogurt in from the slow cooker. Cover it with a clean dish towel and let it sit for a few hours until it’s the consistency that you like. Do note that the yogurt will also thicken some when refrigerated. Play around with it until you figure out how thick or how thin you prefer your yogurt and make notes. That’s the perk of cooking from scratch – you get a product that is truly customized to your preferences.
- The second way I strain my yogurt is new to me, but I’m loving it. I just got a stainless steel yogurt strainer and it’s awesome. I just stick the tube in my yogurt after the incubation time and let it rest about 2 hours. Then the middle fills with the whey and you ladle it out. I normally do this a in three spots down the middle of the slow cooker (over the course of the morning or so) before placing it in the fridge and it works so great. The tube I just rinse off or you can stick it in the dishwasher. It’s a cool thing that if you make yogurt a lot, it’s great to have (it works in the 6 and 8 quart Instant Pots too!).
Slow Cooker Yogurt
Ingredients
- 1/2 gallon (8 cups) whole milk (you'll get a thinner product with a lower fat content milk)
- 1/2 cup commercial plain yogurt that says “Live and Active Cultures” on the tub, I have great success with Mountain High yogurt for my culture
Instructions
- In a large crock pot, add the milk. Add the lid.Turn it on low for around 2 1/2 hours*.
- After that time has passed, unplug the crock pot and let it sit for 3 hours. I always set a timer for these or I don’t remember.
- After the 3 hours has passed, stir in the 1/2 cup of yogurt. Replace the lid of the crock pot and cover with 2 big towels or a blanket. Let rest for 8 to 12 hours (overnight works well). In the morning you’ll have yogurt!
- Place it in a 1/2 gallon mason jar and refrigerate for a few hours before serving. It will thicken up in the fridge. Keep a 1/2 cup of this yogurt for your next batch and say goodbye to buying yogurt!
- You can also let the yogurt strain in cheese cloth in the fridge for a few hours and you’ll get a thicker Greek yogurt!

I’ve made this recipe twice now and haven’t had any problems! I did purchase a Euro Cuisine yogurt strainer on Amazon. The cheesecloth method was just messy for me. I also made a vanilla version. After the milk scalds, I added 1/4 cup sugar and a good splash of vanilla and whisked it in well. Tastes great and my family loves it. We can’t go back to store bought yogurt.
Incubate 3-5 hours at a constant temperature of 110-degrees F. Do not shake or disturb during incubation. After 3 hours, check to see if yogurt is set by gently tilting the container. If yogurt is set and firm, place it in refrigerator and chill for 6 hours before serving. If not, continue to incubate. Check yogurt every hour and place in refrigerator as soon as it sets. The longer the yogurt incubates the tarter the flavor will be. If your yogurt sets within 3 hours, but you’d prefer more tartness, continue the incubation process for another hour or so.
Such helpful tips, thank you!
Could I use commercial kefir as a starter instead of yogurt?
You know what, I have no idea. From my experience with keifer, I don’t think it would work. Maybe try a small batch?
Can I half this recipe?
This is the easiest recipe so far and I can’t wait to try it.
Thanks for sharing.
Just wondering if you need to stir this pretty well to get it smooth? What kind of texture am I looking for?
No, the more you stir it after it sits, the more it breaks down and get thin. You should be able to get a scoop of yogurt after the overnight rest when the yogurt culture has turned the milk into yogurt. If you want it thicker then you can strain it in cheesecloth. Stirring won’t help your texture. It’ll be nice and creamy.
Nothing seemed to have happened with my attempt. What I was hoping to be yogurt was just lumpy milk with a little bit of a tangy flavor. Any ideas what went wrong?
Were you able to test your temperatures with your thermometer? Most of the time if mine doesn’t set it’s because my milk was too hot when I added my culture and I killed it.
Have you tried to double this recipe. We have 8 kids and they love it with just fresh fruit and granola, needless to say it doesn’t last long! Thank you so much for sharing this healthy and inexpensive recipe.
Yes! I make a whole gallon of milk into yogurt almost every time I make it!
Love this yogurt this is my third time making it nd everyone loves to eat it here
Oh no! I mis read your instructions and put the yogurt culture in while the milk was still hot. Will it be ruined? Is there anyway I can save this?
Just add some more yogurt after the heating time! The culture won’t be any good, but if you bought a tub of plain yogurt to start, then just add some more of the commercial yogurt.
Dairy intolerant… Can I make this with soy almond or cashew milk?
