🥛 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. These are the best - thanks Cassie! They are a go to. I'm currently on four weeks with no fruit or sugar/sweetener. The pumpkin spice oats (double the vanilla, double the chia, used ginger instead of cloves, pumpkin/sweet potato purée blend I had in the freezer and coconut cream from a can instead of milk) and they are the best! Thanks for making your recipes so flexible ??????

  2. Hi! Thank you for sharing these. I can't have added sugar like maple syrup and don't like bananas so can you suggest an alternate natural sweetener? Dates?

    Second, for the chocolate recipes, is there something I could substitute like vanilla? Not a huge chocolate fan (I know, I know.) 😉

    Thanks!

    Jill

    1. Canned pineapple or unsweetened applesauce will work to sweeten! Date paste (if you can track it down, or make your own by food processing dates) would also work.

      When it comes to the chocolate ones, just leave the cocoa powder out, and they'll still be delicious!

  3. Actually a question. How do these taste if you hear them up for a minute or two? I generally like hit oatmeal. Does it terribly change the taste or texture?

  4. I hate to sound silly but when you mention unsweetened milk. Do you mean milk alternatives or low fat milk? Thanks ?

    1. Any kind of regular white cow's milk works, but if you use a milk alternative, use an unsweetened one!

  5. @ Cassie

    These recipes were great! Thanks for sharing!

    I tried the classic and the tropical with pineapple, Just have a few Qs

    1. Is the tropical one supposed to be bitter? I used fresh pineapple and canned coconut milk?

    2. are the oats to remain a bit gritty? no entirely soft? I doubled the reciepe so not sure if i didnt include the right amount of liquid.

    1. 1) Nope, you might have gotten a bitter pineapple? Sometimes that happens!

      2) I wouldn't say they are gritty, but they do have a little bit of tooth to them. 🙂

    1. Traditional is best! You can use quick if that's all you have, but they will be a little more mushy.

  6. Thank you for taking the time to post all of these tasty sounding recipes!! I can't wait to make them!!! I never would have dreamed of NOT cooking oats! ?

  7. I've made lots of different variations of overnight oats, but these are by far the most delicious!!! Totally love these thank you!

  8. I'm allergic to flax and chia seeds. Is there anything else I could add to absorb more of the liquid so these are creamier?

    1. Hmmmm...honestly, the oats will go a long way! I recommend leaving out the chia/flax, reducing the milk to 1/2 cup, and adding a couple extra tablespoons of oats.

      1. Tried it with these adjustments and they turned out great! Much more creamy than when I just left out the flax seeds.

        Thanks.

  9. wow, I put the strawberry cheesecake into a recipe analyzer and it came out to 565 calories, 39% fat, 29% sodium and only .5.2 grams fiber. The total carbs were 58g as well. I doubt I would make any of these recipes given these nutritional values.

  10. Hello,

    I was wondering if you could use frozen fruit if fresh fruit is not available at the time? Mostly curious about the strawberries in the strawberry cheesecake recipe.

    Thanks!

    1. I think it would work! The fruit probably won't hold its texture or shape as well, and the colors might bleed into the oatmeal as the fruit defrosts. But as long as you're okay with that, frozen should work!

  11. I've made these and my family and I love them! I double the recipe and the split into thirds - still huge helpings. My teenager will eat the chocolate peanut butter one every single morning until they are all gone. My little one it's banana chocolate chip. So much cheaper and healthier than cereal and I can take it to work when I have to go in early. I'm looking forward to trying all the flavors and about to cruise your site for more recipes! Cheers!

  12. Anyone else having trouble seeing the actual recipes? I can see the pictures and descriptions but the actual recipes are missing. I bought everything to make the peanut butter chocolate kind and now the recipes are gone. Thanks!

    1. We added a new recipe plugin, and it didn't immediately transfer to mobile well. It should be fixed now! Sorry about that!
