How To Make Yogurt (Regular or Greek)

Learn how to make yogurt!  Whether you’re making regular or Greek yogurt, it’s incredibly easy, requires virtually no prep work and the outcome will blow your mind:  Wonderfully thick, creamy, luxuriously delicious yogurt!  This homemade yogurt recipe is SO good and SO easy, you’ll NEVER need to buy store-bought again!

How To Make Yogurt – Regular or Greek Yogurt

How long does it take you to pour a gallon of milk into a slow cooker?  That’s how much prep time is involved in making this gloriously thick, rich, creamy Easy Homemade Yogurt recipe!  And you have full control over its thickness and whether you prefer regular or Greek yogurt!  We’ll show you how to make yogurt, your choice or regular or Greek!

Here is a simple-as-it-gets way of making your own Greek (or regular) yogurt right at home at a fraction of the cost of store-bought.  You’ll end up with almost 2 quarts of Greek yogurt (more if you’re making regular yogurt) for just the cost of a gallon of milk. With this recipe you can make your choice of either regular or Greek yogurt, the difference is simply dependent on how long you strain it.  The longer you strain it, the more whey is removed, the thicker the yogurt becomes.  It’s so easy to tailor it to your preferences.

WHY SHOULD I MAKE MY OWN YOGURT?

There are several advantages to making your own yogurt:  It tastes better, has a better texture, is MUCH CHEAPER, and it’s MUCH HEALTHIER than store-bought because it has a MUCH HIGHER PROBIOTIC CONTENT.  Really, it’s a win-win all around!

WHAT KIND OF MILK SHOULD I USE TO MAKE YOGURT?

For the thickest, creamiest yogurt we recommend whole milk but you can also use 2% and even skim milk.

WHAT DO I NEED TO MAKE HOMEMADE YOGURT?

Besides milk you’ll need some plain yogurt for your initial batch.  Then you can use yogurt from that batch for your next batch and so on.  The plain yogurt will act as a starter culture to introduce healthy bacteria/probiotics to your homemade yogurt.  It is essential that the yogurt you use has live cultures in it.  Most grocery stores sell plain yogurt with live cultures but just be sure to check the label on the container confirm that it has l. bulgaricus and s. thermophilus in it.

You will also need some cheesecloth to strain the yogurt (trust me, it’s much easier than it may initially sound).  I use and recommend this cheesecloth brand because it’s 100% unbleached cotton, is high grade, is very durable for multiple uses, and you get a ton of it.  Overall it’s the best value I have found for the quality.

You’ll also need an instant-read thermometer.  Heating the milk to right temperature and then reducing it to the right temperature are both critical to the success of your yogurt.

The other item you’ll need is either a slow cooker or a large, heavy stock pot.

SHOULD I USE A SLOW COOKER OR A STOCK POT TO MAKE YOGURT?

You can use either with great success and the choice is entirely up to you.

Using a Slow Cooker:

Pros:  The heating process is slow and gentle so there is no risk of scorching the milk and having to throw it all out.  Plus it’s hands free and the milk can heat up over the course of a few hours while you’re doing other things.

Cons:  It takes a lot longer to heat up the milk than if you’re using a pot.  But that’s only a disadvantage if you’re in a hurry.

Using a Stock Pot:

Pros:  It’s much quicker than using a slow cooker.  The milk heats up faster and then all you have to wait for is for it to cool back down and then set.

Cons:  It requires your constant attention and as the milk gets hotter it requires constant stirring in order to prevent the milk from burning (and it can burn very easily if you’re not paying attention).

You can see that both have their pros and cons and it purely comes down to personal preference.  I use and like both methods but generally use my slow cooker/crock pot more often because of the hands-free convenience of plugging it in and going about my daily tasks.  Any crock pot or slow cooker will do the job.  I use and love my Hamilton Beach Stay or Go 7 Quart Slow Cooker.

DO I HAVE TO BRING THE TEMP UP TO 180 DEGREES IF I’M USING PASTEURIZED MILK?

Virtually every yogurt-making recipe will tell you to heat the milk to 180 degrees F before bringing it back down to 110 degrees F to inoculate it with a starter culture.  The question you may ask yourself is, if I’m using pasteurized milk already do I need to heat it to 180 degrees or can I just skip that step?

Here’s what I’ve learned:  Heating it to 180 degrees isn’t for the purpose of killing unwanted bacteria as much as it is for creating a thick texture.  The heat changes the structure of the proteins in the milk and enables it to thicken into yogurt.  I wanted to test that for myself and heated the milk to just a little over 110 degrees, added the starter culture, and proceeded from there.  It hardly thickened at all.  But when I heat it to 180 degrees, then let it cool to 110 degrees before adding the starter, it thickens up beautifully.

WHAT IS THAT YELLOWISH LIQUID THAT’S LEFT OVER AFTER I STRAIN THE YOGURT?

It’s called whey.  When making homemade yogurt, you’ll always end up with some whey as a by-product.  The longer you strain the yogurt, the thicker it will get, the more whey it will yield.  If you strain it to full capacity for an extra thick Greek yogurt, you’ll end up with about 8 cups of whey, but every batch will be different.

Whey is milk minus the fats and solids.  It’s basically water with lactose and protein.  And it’s the protein that’s the valuable ingredient here.  Milk contains two types of protein, casein and whey.  Most of the casein ends up in the yogurt and the whey is in the liquid by-product.

WHAT CAN I USE THE LEFTOVER WHEY FOR?

I’m so glad you asked!  Whey is a great source of protein and is used in powdered form in protein shakes and protein bars. But how can you this leftover liquid whey?  Here are a few ideas:

• Use it in place of water when you’re making broth or soup for an extra rich broth.
• Use it in place of water for baking bread or pastries.
• Add it to your smoothies of an extra protein boost.
• If you have a vegetable garden, use it lower the pH level of your soil if you’re growing things that prefer soil with a higher acidity level, like tomatoes.

CAN I FREEZE THE WHEY TO USE LATER?

Yes, it can be frozen for up to 6 months.

DO I HAVE TO USE A GALLON OF MILK OR CAN I MAKE A SMALLER BATCH?

This recipe calls for a gallon of milk because this yogurt will keep for a good 2 weeks in the fridge, giving you plenty of time to finish it off.  (Note that a gallon of milk won’t yield a gallon of yogurt.)  If however you would prefer to make less you can absolutely cut the recipe in half and use a half gallon instead.  Just be sure to remember to reserve enough of the yogurt to act as the starter for your next batch.

HOW MANY CALORIES AND HOW MUCH PROTEIN ARE IN MY YOGURT?

This is a question I get frequently.  Calorie count and protein content will depend on how much whey was removed in the straining process and there really isn’t a way to measure that. Even calories are hard guess because through the straining process the end product is much more condensed that the original milk product.  The best we can do is estimate.

TROUBLESHOOTING 

“My yogurt didn’t set and I have yogurt soup!”

There may be an occasion or two when your yogurt doesn’t set properly.  I’ve made probably close to 50 batches and fortunately it’s only happened to me twice but it was nevertheless disappointing.  Many factors can be at play for a failed batch, anything from the first step to the last. If you’ve done everything right and have followed every step correctly from start to finish, all I can say is that the yogurt-making process involves fragile live bacteria and sometimes, well, they have a mind and will of their own.  And if you’re using store-bought yogurt as your starter culture, it may claim to have live bacteria that is…no longer live.  The only thing to do is try again with a new batch.  But just because it failed turning into yogurt doesn’t mean you can’t still enjoy it.

Don’t throw out that “yogurt soup”!

Throughout Europe and other parts of the world you can get a variety of delicious plain and flavored yogurt drinks.  You can drink your yogurt milk and you’ll still be benefitting from those healthy probiotics.  Add some honey or flavored syrups or blend in some berries or fruits of your choice and enjoy it in smoothie form!

DELICIOUS WAYS TO EAT YOGURT

The ideas are almost endless.  Here are a few:

• Add fresh berries or cut up fresh fruits to enjoy with your yogurt along with a sprinkle of cinnamon and/or a drizzle of honey or maple syrup for a healthy breakfast or snack.
• Make parfaits with fresh fruit and granola.
• Blend it with fresh or frozen fruit or with nuts, peanut/cashew/almond butter, chocolate, etc. to make smoothies.
• Add other ingredients and seasonings to use as a sandwich, toast or bagel spreads.
• As the base of a savory dip for oven-baked chips, bread or raw veggies.
• As the base of a sweet dip for fresh fruits or toasted cinnamon pita strips.
• Use it in place of mayonnaise for ranch and other creamy dressings.
• Make homemade tzatziki sauce.
• Replace sour cream and buttermilk with yogurt in baked goods like cakes, muffins and pancakes.
• Make yogurt fruit popsicles.
• Use it in place of sour cream for things like tacos, enchiladas and burritos.
• Use it in place of mayonnaise for egg, tuna, chicken and potato salads.

The way I most commonly enjoy my yogurt is simply stirring in a spoonful of fruit preserves with a little powdered stevia for a healthy, low-carb treat to satisfy my sweet tooth.  Another favorite way is to make vanilla yogurt by stirring in some high quality vanilla bean paste.

HOMEMADE YOGURT RECIPE

You’re going to love how rich and creamy this yogurt is – it’s almost like eating dessert!

Let’s get started!

IF USING A STOCK POT INSTEAD OF A SLOW COOKER:   If you’re in a hurry or don’t have a slow cooker you can use a stock pot.  Simply heat the milk in a large stock pot over low to medium heat. Just be sure to stir it regularly, especially as it gets hotter, to prevent the milk from scorching. Then follow the rest of the instructions as written.

Pour the milk into the slow cooker and set it to HIGH.  Go about your business, it’ll take at least 2 hours (usually longer) before the temperature’s up to 180 degrees.  An instant-read thermometer is the best kind to use to check the temperature.

Once the temperature is up to 180 degrees, turn off the slow cooker or stove top and let the milk cool to 110 degrees F.  Again, go about your business, this will take at least another 2 hours.

Once the temperature is 110 degrees, mix a little of the warm milk into the room temperature starter yogurt, then gently but thoroughly stir it back into the milk using up and down, left and right motions (not circular).  Turn off the slow cooker and close the lid.

Wrap a large bath towel around the slow cooker and let it sit undisturbed in a draft-free, room temperature (or warmer) area for 10-12 hours or overnight.

When you remove the lid you’ll find that the milk has thickened and the whey has separated.

Look at that fabulous thick texture!  The transformation is almost magical.  You’ll be so excited the first time you make this!  I still get excited every time I lift the lid.

Line a colander with some cheesecloth.

I currently use this cheesecloth.  It’s great quality and you get a lot of it for an excellent price.

Pour the yogurt into the cheesecloth.  If it doesn’t all fit (depending on the size of your colander), let the yogurt strain until there’s room enough to add the remaining yogurt, then continue to strain.

Depending on how thick you want the yogurt, this will take several hours.  For thick Greek yogurt, you’ll end up straining it for at least 4 hours.  That will also depend on the gauge of the cheesecloth.  Set the colander on top of a large glass bowl.  If leaving it to strain for several hours, you can put it in the fridge if you prefer and let it strain there.

See the liquid in the glass bowl?  That’s whey.  Glorious protein.  See blog post above for ways you can use that whey.

Store the yogurt covered in the fridge for up to 2 weeks.  When you’re ready to make another batch, use some of the previous batch for the starter culture.

If fully strained to make Greek yogurt, you’ll end up with about 2 quarts (8 cups) of whey and 7-8 cups of Greek yogurt.

You’ll end up with less whey and more yogurt if you strain it less to make regular yogurt.

Cook with it, bake with it, eat it plain or with a variety of mix-ins, whatever your heart desires!  (See list of ideas above.)

Enjoy!

Instructions

• IF USING A STOCK POT:   If you're in a hurry or don't have a slow cooker you can use a stock pot.  Simply heat the milk in a large stock pot over low to medium heat. Just be sure to stir it regularly, especially as it gets hotter, to prevent the milk from scorching. Then follow the rest of the instructions as written.

  IF USING A SLOW COOKER: Pour the milk into a slow cooker set to HIGH and close the lid. It will take 2-3 hours before the temperature of the milk is up to 180 degrees F. Check it with an instant-read thermometer. Once it's at 180 degrees, turn off the slow cooker, close the lid, and let the milk cool to 110 degrees F. This will take another 2-3 hours. Once the temperature is between 110 and 115 degrees F, add some of the warm milk to the plain yogurt, stir to combine, and then gently but thoroughly stir the mixture back into the milk in the slow cooker using up and down, left and right motions (not circular). Turn off the slow cooker and close the lid.
• Wrap the slow cooker or stock pot with a large bath towel and let it sit undisturbed in a non-drafty place at room temperature or warmer for 10-12 hours or overnight. The milk will have thickened and the whey will have started separating from the milk.
• Line a colander with a cheesecloth and pour the yogurt into it. Set the colander over a large glass bowl and let it strain at room temperature for several hours, until you've achieved the desired thickness (length of straining time will also depend on the gauge of the cheesecloth.  I use this cheesecloth - excellent quality and you get a lot of it for a great price) For thick Greek yogurt plan on at least 4 hours. You'll end up with about 8 cups of whey and 7-8 cups of Greek yogurt.
• Store the yogurt in the fridge in an airtight container, preferably a glass bowl for up to 2 weeks. When ready to make another batch of yogurt, use a cup of the previous batch as the starter culture.
• The whey can be reserved for a variety of purposes (see recipe post for some ideas).

Notes

**UPDATE: Yes, you CAN use raw milk. It's more temperamental though. If after the wait time the yogurt still isn't firm, turn the slow cooker back on to "warm" and let it sit another 4 hours or until thickened. Raw milk yogurt often tends to be clumpier.
**You don't have to use the slow cooker method. For a quicker method simply heat the milk in a large stock pot over low to medium heat. Just be sure to stir it regularly, especially as it gets hotter, to prevent the milk from scorching. Then follow the rest of the instructions as written.
