🥛 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. Thank you so much for posting these! I started making overnight oats a few months ago and they have been filling but kind of boring. I tried the chocolate peanut butter one you listed and it was delicious. I just put a batch of strawberry cheesecake ones in the fridge. I can't wait to try them. Eventually I will make all of these, they look delicious.

  2. I love these!! Just made them this morning and came out really delicious, but they weren't as creamy as I thought they'd be. They seemed a little liquidy. I did all the measurements correctly, and even added a tiny extra chia. Should I maybe cut back on the milk by a little? Thank you <3 🙂

  3. What exactly is unsweetened milk? I assume it's not the normal gallon of milk I get from the store but what do I know (I'm just a dumb man!).

  4. My favourite is berries dried banana... I mix any plant milk, oats and chia and cover it with frozen berries (raspberries, blueberries, strawberries whatever) and in the morning I add dried banana to make it crunchy and honey... I love them

  5. Thank you for getting me started! The classic recipe is my base to all of my overnight oats now and I've been having a lot of fun experimenting with different fruits and flavors.

    1. I don't see why you couldn't sub your own sweetener. I plan to sub the plain yogurt for the Oikos Triple Zero that is stevia sweetened and skip the sweetener. I think the sweetener in the yogurt will be enough.

  6. I worked out the calories for some of these, and while I do enjoy them I probably won't be making any of them again except as a mega treat! Calculations come from myfitnesspal.com

    Carrot cake recipe - 431 calories (with 1 tbsp honey)
    Chocolate peanut butter - 548 calories (with 2 tbsp maple syrup)
    Chocolate coconut - 610 calories (with 1 tbsp maple syrup)

    1. With the protein and fiber, these aren't that bad for a meal, they're definitely not a snack. They certainly are a healthier option than something else with the same calorie count, and should keep you full until lunch. They can also be made with less calories, depending on what kind of ingredients you're using. Not sure which items you're using, since you didn't mention your specific ingredients.

  7. Hi Cassie! I love the overnight outs idea! I didn't Know about them until I was looking on Pinterest for oatmeal recipes for my daughter that just turned one year old. She loves oatmeal but I can tell she was getting tired of the same baby otmeal I was feeding her. My question is can I give it to her warm like heating it up on the microwave? Or would that ruin the over night oats? I'm definitely going to try and give it to her cold but if she doesn't like it because it's cold and she is not use to it can I warm it up? I was reading through the comments of you had answered the cold or want question but I didn't see any responds..

  8. Dear Cassie,

    Can i make a lot of batch and put it into the fridge for let say 3 days? I know this is overnight oat and it is better to consume within a day.

    Thanks

  9. Cassie, these recipes all sound so delicious! What is your preference..maple syrup or honey? You suggest either option but I would like to know your 'go to' sweetener. Thank you!

  10. I have a stupid question (I think). What is "heaping" rolled oats? Ive always seen that, but I never really knew what it meant. Can you enlighten me? 🙂 And also, can I use almond milk as a substitute?

    1. It just means that you don't want to level-off the measuring cup. So basically, fill that measuring cup as high as you can!

      1. Ohhh! That cleared it right up. 🙂

        Anyway, Im using Almond milk, but its sweetened. Should I leave the sweetener out? Or I should still add a bit (to reach that right amount of sweetness)?

        And also, can I use brown sugar? How can I substitute it? Maple or honey is really expensive from where I come from.
