🥛 The Ingredients You Need

Vanilla overnight oats ingredients on a countertop
  • Oats: I recommend rolled oats here. Quick cooking or steel cut oats won't have the same texture (but they are great in my slow cooker steel cut oats recipe).
  • Greek Yogurt: any plain Greek yogurt will do, or you can use homemade yogurt, just make sure to strain it first (here's the yogurt strainer I use every week)
  • Chia seeds: help them thicken up the oats as well as add protein and fiber, you can also swap in equal amounts of flax meal
  • Honey or maple syrup: I prefer the flavor of maple syrup in these oats, but either option works-or leave out the sweetener all together if you want to cut back on sugar.
  • Flavoring: the recipe listed here is for the base vanilla overnight oats recipe, but depending on what flavor you are making, you'll add all kinds of yummy goodies!

Make sure to check the recipe card below for the full ingredients list, along with quantities and my expert tips and tricks.

🔁 Variations & Substitutions

  • Make it vegan: Use maple syrup, plant-based milk (almond milk or oatmilk work great) and vegan Greek yogurt
  • Make it gluten-free: These oats are naturally gluten-free as long as you choose certified gluten-free oats.
  • No chia seeds? Swap in equal amounts of ground flax.
  • Up the protein: Add a scoop of vanilla or unflavored protein powder!
  • Make it sugar-free: Drop the sweetener and add a ½ mashed ripe banana. Or use stevia or monk fruit sweetener in place of the maple syrup or honey if you prefer.

🙋🏻‍♀️ Healthy Overnight Oats FAQs

Are overnight oats actually healthy for you?

Yes! Overnight oats are packed with protein, fiber, and a good mix of macronutrients to make for a balanced breakfast.

Can you make overnight oats with steel cut oats?

Yes, you can use steel cut oats to make overnight oats but the final texture will be more chewy than creamy. Because steel cut oats are inherently less processed, you should increase the amount of liquid by ¼ cup, and prepare for a chewier oatmeal in the morning. 

How long do overnight oats last in the fridge?

The recipes with fruit mix-ins, eat within three days. The ones without fresh fruit, you could get by with letting them chill in the fridge for up to a week.

  1. I'm a grandmother myself now and I recall my grandmother putting oats , milk & her special secret ingredients ? Into a pot the last thing before she went to bed each night. She would sit it on the side of her slow combustion stove and when she came out in the morning & my grandfather had lit the stove and the gentle warmth that radiated to the side plus overnight absorption meant the oats/porridge would be ready. Now that was in the 50's.
    That's the original overnight oats ?

  2. i tweaked up your classic overnight oats recipe and made it a thai overnight oats recipe!

    switched the greek yogurt for sweetened condensed milk, the unsweetened milk for coconut milk.
    my add ins are diced ataulfo mango w/ sliced strawberries (the morning i eat them) and a sprinkle of shredded coconut!

    delicious and not as sweet as you might think it is!

  3. -Thanks for these recipes! I've made overnight oats before, but you have a lot more information than I've seen with other recipes, which is really helpful.
    -I tried the chocolate coconut oats! Very yummy! The ratio of cocoa powder was too high for me, though, so the next time I cut that almost in half and then it was perfect.
    -An FYI for other folks: quick oats are not substitutable (is that a word?) for the regular oats. I tried that once in the past and it was way too mushy, not a good texture at all.
    -I'm looking forward to trying your other recipes. Thanks again!

  4. I'm very excited to try these recipes! I've started with the banana chocolate chip. I had everything on hand except the chia/flax so I'm leaving it out and hoping for the best

  5. Ok, so I'm a high school student tryna make more of my meals so I can control what is in what I eat. However breakfast and lunch are major softspots for me but also, as a student, very important. This recipe has done lots to solve my problem because I just whip some up at night and in the morning I just grab and go! Especially because my mornings are often frantic due to me sleeping in, this can give me a great lunch or a breakfast if I'm up early. Or even an after-school snack! Plus it's so easily customizable. As of right now I recently put a batch with protein powder in the fridge. So really, thanks! This simple concept is incredibly valuable to anyone trying to eat less processed.

  6. Can you tell me the nutritional value for the basic overnight oats? I'm counting calories, sodium, and fat.

  7. I am enjoying the recipes but my last two batches had problems. Using the basic recipe with unsweetened almond milk, plain yogurt and maple syrup, by morning I had several pieces of oats that had a bluish-green color on them (mold?). Any suggestions are appreciated.

  8. I'm currently sitting here eating the chocolate and peanut butter overnight oats, my first ever attempt at them, and they are so good! It's quite rich so I can get 2-3 days out of the one serving. I think I'll have to cut back on the cocoa powder next time though, I slightly overestimated how much a tablespoon was when using a dessert spoon haha. Can't wait to try the other recipes!

  9. Cassie,
    I have three in my family of six that are not oatmeal lovers, so would this method be better to try with them? Also I do not have any chia or flax seeds, so could I just leave them out. Thanks!

  10. Just prepped these about 15 minutes ago, and I had one of those moments. You know the ones, in those informercials, where someone is trying to do a simple task but failing miserably at it because they don't have the gadget that's up for sale. Or, if you'll allow me to be more crass, what the Internet refers to as an unclear encounter with a ceiling fan.

    There were two instructions. Mix it all together, and put it in the jars to soak overnight. Simple, right? WRONG! All my chia seeds wanted to float on top, and all my oats sunk to the bottom (I made the plain recipe as a trial one, and good thing, too). When I attempted to spoon my stuff out, which was quite spillerific, I couldn't help but get too much fluid in the first jar, about 3/4 liquid, nearly all the chia seeds, and 1/4 oats, and the inverse for the second. Ahhh, what has happened, there's milk everywhere!

    A word of advice to those who are challenged in their manual dexterity. Measure your dry and/or solid stuff (oats, chia, spices, fruit, nuts, etc) into the jars directly as they're empty. Then mix all your liquids (milk, yogurt, syrup/honey, etc) separately. This is also a great excuse to just mix stuff in your measuring cup, now that you won't be filling it up as much, and allows for pouring instead of spooning when you go to cover your dry ingredients with the mixture. The yogurt and sticky stuff will come out easily once blended with the milk and you won't have to scrape it out of your measuring device when you're ready to move it; just use yogurt > milk > everything else as your order for adding stuff in; you can shake your table spoon around in the milk to make sure you get every last bit of honey or maple syrup out.

    Or you could not be a massive klutz and get your life together enough that you can follow to simple instructions. Whatever.

    1. Whoops! This is totally something I could see myself doing. But I love your writing style and sense of humor!

  11. Can these be made ahead and FROZEN, then thawed out? I find my mornings to be so irregular that I find shakes work best for me for grab-and-go. .. but I have A LOT of oats that need to get used up. IF ANYONE HAS TRIED FREEZING THEM: what was the texture like, in comparison to one kept in the fridge? Thank you!

  12. I made the chocolate peanut butter oats last night and they were delicious. I couldn't eat the whole serving so I now have a delicious dessert waiting for me tonight when my sweet tooth hits. I didn't add the vanilla or salt and I only added one tablespoon of maple syrup as I'm trying to cut down my sugar intake. So quick and easy to make. I can't wait to try a different recipe tonight.

  13. In your description for peanut butter overnight outs, you stated that for gluten free dietary substitute you. Should use gf oats however peanut are legumes containing gluten and I suppose should be mentioned too

    1. Peanuts actually don't contain gluten! Gluten is a protein that is found in wheat, barley, rye, and their derivatives, so peanuts are safe for those eating gluten-free!

  14. Ok, so I made the chocolate-coconut but added a twist: I crushed up some sliced almonds which gave it a wonderful crunchier texture and now it tastes like almond joy!!

    I also made up a jar of blackberry-vanilla: use french vanilla yogurt, add 1/8 tsp cinnamon, about 1/2-2/3 cup blackberries (fresh crushed with a fork or frozen and thawed with some juice). So creamy yet lightly fruity and yummy!

  15. Cassie,
    My adult vegetarian son has been pushing me to try overnight oats. I was't really motivated until I took a look at your recipes! They look amazing! As we're going through a kitchen remodel, this is the perfect time to jump in. Thanks!
    I also wanted to mention that regarding sweeteners, natural maple syrup has additional nutrional benefits. Check out http://www.purecanadamaple.com/benefits-of-maple-syrup/maple-syrup-nutrition/ for more info!

  16. I first heard of overnight oats last year and completely forgot about them. Now it's the HOT weather at home and I was looking for a non-tea alternative for breakfast. Thank you for all the recipes! I just bought myself some oats, I can't wait to start this adventure. 🙂

  17. I don't think salt is needed in any of these recipes. I make overnight oats all the time and never use salt. Salt...no no no

    1. The salt helps bring out the other flavors, but if you want to leave it out, you certainly can!
