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 (you can find it on Etsy for $25) 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 is an easy, healthy and inexpensive way to make homemade yogurt without a yogurt maker. Prepare in five minutes, go to bed, and wake up to a freshly made breakfast!
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!
Notes
- *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 menat to bring the milk down to around 115-110 degrees so that it’s still warm but won’t kill your yogurt culture!

I am excited to try this recipe next weekend, but we need to order a thermometer first. I have one question: when straining the yogurt, should I leave it on the kitchen counter or put it in the fridge? Thanks!
You can do either one, I normally strain it at room temperature and then move it to the fridge just for space purposes.
After wanting to try yogurt-making for years, I made this yesterday and was so excited to get up this morning to see if it worked. It did! Thank you so much for this recipe! You explained everything in such a clear way that really helps for someone trying this for the first time. I’m definitely going to keep making this! Thank you, thank you, thank you!

Hooray! So glad it worked out for you!
What did I make? Cheese? Or just sour milk? I must have gotten cocky because on my third try —after two great, creamy, white yogurts— I didn’t use my timer (actually accidental—there was a lot going on) and the milk got a film at the scalding and cooling point. After the 12 hour rest it looked yellow and separated with a lot of whey.
Any idea what went wrong or what I have now?
I still put it into jars and left it on the counter for now, and am hoping for the best tomorrow!

It’s just processed a long time and that’s the whey on top. I’d just strain it off, it’ll be fine!
AH! I was making this and when I unplugged the pot and put towels over it at 110*, I woke up 12 hours later and checked the temp only to find it had gone up to 174*!!!!!
What the heck would cause that? Too much warmth from the Mexican blanket and towel I used?
I’ve never heard of that happening! You much have a very strong slow cooker or a liner that is extra thick, doesn’t make a bit of sense to me.
How long should I let the milk scald in my crockpot? It finally hit 180*F at the 2.75 hour mark. Should I let it sit longer, or should I remove it from heat to let it start to cool back down to a safe temp for the yogurt?
Once it reaches the temp, it doesn’t need to hold it.
The first time I tried this, I made the loveliest, small curd cottage cheese/tangy ricotta. Trying again this time, following the temp instructions EXACTLY. Now I know how to make TWO dairy products on my own. 😉

You’re not heating the milk high enough in the first step to get the protein to firm up. You need to get it to 200, then cool to the 115 or so to add your culture. You’ll get the right thickness doing it that way. Works every time.
I just made this for the first time, and I was impressed with how easy it was and that it actually worked! I ended up using a strawberry yogurt for my starter and whole milk – there’s a little strawberry flavor which is tasty! I then strained it with a dish towel and colander to make it more like Greek yogurt – so good! Thank you for this recipe!

Hello do you strain before putting the yogurt?
You can strain this after it has sat overnight with the yogurt in it 🙂
I;m allergic to dairy. Will this work with Soy Milk?
I haven’t tried it, has anyone else had success?
I have 4L of milk that just passed the bb date. Im going to make it all. Can I double the time for it since its double the recipe?
No need to adjust times, just double the amount of culture you are using.
Hi! I’m attempting this recipe for the 2nd time. First time was a complete failure. We live in upstate NY and it’s still really cold here and the house is old and can’t get it warm, I just don’t think my yogurt stayed warm enough in the crock pot overnight (wrapped in a towel, in my oven). So, I’m trying again – this time there’s a film layer on the top of my milk in the crock pot (after heating to 180 – haven’t put the starter in yet, its still too hot). Do you think it will be ok? What could cause this? I know I need to get a better thermometer. I also used a crock pot I don’t use as much and I don’t think is as consistent, it’s just smaller and I didn’t want to bring out my big one.
Yes, the film happens to me and I take it off before adding my yogurt culture, no issue there! It’s a scalded milk thing. Keep us posted! I’d like to know how it works for you!
Thank you! I am impressed with how it came out. I had taken some of the film off, as much as I could, but I know I didn’t get it all. The yogurt came out a bit stringy – is that normal for you? It’s more of a drinkable yogurt consistency, ideally I’d like it a little firmer, but I can eat this with no problems. Would letting it sit longer help to firm it up?
It’ll get over the stringy when it’s cold and it’ll thicken up a bit when cold too. That being said, you can strain it to make it thicker if you like. I almost always strain mine as we like a Greek yogurt style textures, there’s notes in the post but I normally just line a colander with dish towel and set it in a large bowl and let it drain for a few hours. Straining out the whey makes it thicker! Congrats on the yogurt!
I have yet to make this yet, but could you add sugar or a fruit mixture so this doesn’t have the taste of plain yogurt?
I just tried it with adding a can of sweetened condensed milk and it worked fine. We normally just sweeten our plain yogurt with jam or honey when serving but it was fun to try something else and of course the family cheered!
Perfect, thanks for the tip!
