Learn how to make overnight oats with kefir milk. All you need are oats, kefir milk and a bit of maple syrup or honey for oatmeal with the best texture.

I recently took a poll on Instagram, and almost everyone said that breakfast was the toughest meal of the day. Sure, lazy weekend breakfasts are great, but the weekdays are a different story. That’s where these kefir overnight oats sure come in hand.

The best part about these overnight oats – they only need 3 ingredients to be delicious. Why is that? Kefir is thicker than milk but thinner than yogurt. Let me explain.

I’ve very picky about my overnight oats because I love oatmeal so much. Overnight oats with just milk or non-dairy milk are too thin and there isn’t enough liquid in yogurt to saturate the oats to soak them. Therefore, for good oats, you need a combination of both. Which, isn’t so bad it just takes a bit more stirring and more ingredients.
But if you want an easier and probiotic rich ingredient that makes whipping up overnight oats a breeze, opt for kefir.

Why is kefir best for overnight oats?
Like I said, kefir is thicker than milk and thinner than yogurt, giving it the perfect consistency to both saturate the oats so they can soak and thicken the mixture so it’s satisfying, not runny.

Before we go further, let me explain what milk kefir is.
Kefir milk is really just fermented milk. It sounds kind of funny if you haven’t tried it, but it’s really just very tangy, not rancid or rotten tasting at all. Honestly, it kind of tastes like tart, drinkable yogurt. Most kefir milk is fermented with kefir grains which are a certain type of culture. It’s very probiotic-rich so it’s great for your gut.
I like cows milk kefir but many people also drink goat or sheep’s milk kefir. As I said, it is thicker than milk, it gets that way during the fermentation process. It’s easy to make your own if you grab some milk kefir grains (it’s a VERY cheap thing to do) or pick some up at the store. You can use the plain kefir, or do a second ferment and add fruit/flavor for flavored kefir. You can buy plain or flavored, but the flavored, store-bought varieties usually have added sugar, like flavored yogurt. For this recipe, I like to use plain kefir and add my own sweetener and/or fruit.

How do you make this recipe?
By gosh by golly, this is the best part. You literally dump everything in a glass jar, screw on a lid (I use these nonreactive, plastic ones for anything fermented) and shake shake shake until everything is mixed.
You’ll see that in the recipe below I call for oats (old fashioned rolled are best), plain kefir milk, and maple syrup or honey. You can also add sea salt, vanilla, fruit, and/or some seeds of choice to take things to the next level. It’s customizable to you!

Kefir Overnight Oats
Learn how to make overnight oats with kefir milk. All you need are oats, kefir milk and a bit of maple syrup or honey for oatmeal with the best texture.
- Prep Time: 5 minutes
- Total Time: 5 minutes
- Yield: 1 serving 1x
- Category: Breakfast
- Method: No-bake
- Cuisine: American
Ingredients
- 2/3 cup old fashioned rolled oats*
- 1 cup plain kefir milk (I used whole milk but any fat percentage will work)*
- 1 Tbsp. maple syrup or honey
Optional add ins:*
- 1/3 cup fruit or berries (optional)
- 1 pinch sea salt
- 1 splash vanilla
- 1 Tbsp. chia, flax or hemp seeds
Instructions
- Add the oats, kefir, and maple or honey to a glass jar with a lid.
- If you’re using any add ins, add them at this time.
- Screw the lid onto to the jar (I like to use plastic, non-reactive lids with fermented foods), and shake until everything is combined.
- Place the jar in the fridge overnight, or for at least 6 hours, and serve! You can make these as soon as 3-4 days before you want to enjoy them, so prep a few at a time!
Notes
- Quick-cooking oats will work, but I prefer old fashioned rolled oats. I have not tested this with steel cut.
- Gluten-free oats are great – oats are naturally gluten free, but sometimes they are processed in facilities that work with gluten-containing food and can be contaminated.
- If you have flavored kefir, it is most likely sweetened. If so, taste the mixture before adding any excess sweetener. It may be sweet enough as is and you can omit the maple/honey. If you avoid processed sugar, opt for plain kefir.
- Any of the add ins are optional. The recipe will work and be delicous with just the oats, kefir and maple/honey. The add ins just take it to the next level.

Hi,
I prepped this recipe today. Made 4 jars for the week.
Look forward to eating for breakfast.
so glad!
The 1 tbsp chia seed is pre-soaked or added as it is just before breakfast or grounded chia seed?
Imo the best way to include chia seeds is altogether with the mixture and allow it to soak overnight, it results in a gelatinous, chewy texture. If you prefer for them to stay crunchy, you can add them right before eating.
Congrats!!
Made this earlier this week and had a delicious breakfast for 2 days. It is a simple and healthy option to have in the morning. Very filling too. Thank you for sharing this recipe.
