🥛 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. Hey Cassie - I love these overnight oats! I just have a couple of questions; is ground flax the same as LSA? also, we don't have ready access to plant-based yoghurt in Western Australia, so is Greek yoghurt ok on most occasions? Thanks 🙂 teresa

  2. Absolutely delicious combinations and recipes for everyone's tastebuds, and a serious breakfast. Easily 3 to 4 portions for those who want to use this as a side instead. Very filling, and unbelievably gratifying tastes. (coming from an non oatmeal lover!) Kudos to you for this mind changing post;-) J

  3. These sound awesome! Definitely trying one this week. Can these be warmed up in the microwave? Thinking about winter time. Thank you

  4. Where I live is hadr to find a nice 250 ml jars but I found 300 ml. Would it be okay if the jars were a bit bigger or do they have to be fully filled?
    Sorry if that question is stupid 🙁 I'm just starting my overnight oats adventure! 😀

      1. Hi, Caitlin! You can definitely use frozen fruit. Just add it in like you would fresh fruit and stir it all up the same! Depending on which fruit you're using it might not hold its shape, as well (strawberries tend to break down more, but blueberries hold their shape better). So as long as you don't mind that, the flavor should still be spot on! I use frozen fruit in mine all the time =)

  5. Hello Cassie,
    I'm looking for a great recipe for my breakfast. I often oversleep in the morning and don't have time to prepare it. So I found your article 🙂
    Thank you so much for that. I found my new breakfast!
    Also all the different recipes are very very great. I really feel the love that you have invested here.
    I will buy everything today and try out the recipes right away 🙂
    Is it possible to prepare the overnight oats 2-3 days in advance or is it better to always make them fresh the evening before?
    Dearest greetings,
    Nadine
    P.S.: My English isn't the best, but I hope it's enough 🙂

  6. I made the pumpkin spice overnight oats last night and chilled for ten hours. This morning I had a runny mess, , the consistency was thinner than pancake batter. The taste was that of unsweetened, bitter spices. If I had had time I would have thrown in some flour and tried to bake it, so as not to waste the money that went into making them. I followed the recipe to the letter. I'm so disappointed that my very first attempt at overnight oats was such a failure. I want to try again with a different recipe. Maybe add a tiny bit of powdered stevia.

  7. I've been making these every weekend for years now. I use half the milk, and half flavored creamer. I skip the flavored creamer and use flavored yogurt sometimes. My favorite uses Southern Butter Pecan creamer, and chopped pecans, but the possible variations are endless!

  8. I have researched and love Stevia as a replacement for sugar. It is a very safe product and has been used for many years overseas.

    1. You can leave out the yogurt completely (we suggest swapping in 1/4 cup of milk for the yogurt), but it won’t be quite as creamy. The flavor will still be good, though!

  9. I, also, am in love with overnight oats. I have never really liked cooked oats but for some inexplicable reason love these cold. My DH heats them up though. I can't wait to try some of these recipes, especially the cheesecake one. I usually just dump everything in a jar (pint) and shake it up, this seems to work very well for me but will probably have to use your method with the cream cheese. I love nuts in mine, any kind that is on hand. For anyone who doesn't want to be totally healthy... try some Nutella.

  10. I've almost tried all of the flavours now and they're all amazing!! It's like having dessert for breakfast 🙂

  11. This is the best, I cannot wait to make all of these. Just wondering about the chia because I have diverticulitis if if ok for me to have them. I love this site it answered all my questions and I am so grateful you explained everything perfectly. Thank you thank you thank you

  12. I'm diabetic and I do tweak these recipes a bit for my needs. But I absolutely love them and so does my blood sugar! I feel full until lunch time so no snacking in between. My blood sugars are ranging between 75-90. The perfect breakfast or fast lunch for me. Thanks for the recipes!

  13. So glad I stumbled across these recipes. I have mainly made the basic recipe (added dried sour cherries/frozen sour cherries/blueberries, etc) and the chocolate PB. I am counting macros so I do have to put the recipes into My Fitness Pal to get my nutritional info. I found that using PB Fit powder in the PB and Chocolate one is divine!! I also add a scoop or half scoop of protein powder (dealers choice) to balance out the carbs. I love to add half a banana to every flavor but I leave out the maple syrup sometimes. Perfectly sweet. I am going to have to give some of the other flavors a try....hubby loves carrot cake and strawberries are about to be in season so.....:) Thanks for sharing.
