🥛 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 have made four of these recipes so far - banana chocolate chip is my FAVORITE! We had the pumpkin spice this morning - it was a little too moist for my taste (I would cut back on the milk or yogurt next time since the pumpkin puree is also like a liquid - the liquid to oats ratio seem to work best at 2:1) I also thought the spices were a little overpowering on the pumpkin - maybe a little less clove next time? But overall these have been such a delight. Thank you for sharing!

  2. Your overnight oats have changed my breakfast for the better. I used to reach for easy baked goods while running out the door. Now, I make jars of your overnight oats in Sunday and I am good for the week. I love the banana chocolate chip and I took your base recipe and made a cinnamon brown sugar raisin combo. Tastes like a Cinnamon roll. Yummy. Thanks for my healthier breakfast!

    1. You know, I've never tried it! It might work, although depending on the milk and yogurt you use, you might have separation issues. If you try it, let me know!

  3. Thank you so much for these recipes! I kept trying overnight oat recipes and choking them down because they are healthy, but I hated them. I look forward to eating these, because they are actually really good.

    The only substitution I make is agave syrup as the sweetener.

  4. amazing, amazing! Have tried original and peanut butter choc and put in small mason jars. So cute and so delicious and healthy. AND FAST!

  5. I just made the banana chocolate chip today. I just tried it before going to bed. It's amazing! I don't think I've ever been so excited for breakfast before!

  6. These recipes look great! However, isn't the whole purpose of soaking oats to protect our guts from phytates that inhibit nutrient absorption? Am I missing something? Because there are all kinds of these things on Pinterest saying "overnight oats" but they don't add an acid to help break down the oats for easier digesting, and they put it in the fridge. I know the science behind this so I'm wondering if there is something I missed?

    1. If you'd like to/need to soak your oats to aid in digestion, then these aren't the recipes for you! 🙂 Basically, the idea here is to give you an easy/tasty pre-made breakfast option—you won't get the benefits of easier digestion from this option.

  7. These are awesome, and I was just planning on enjoying them and not commenting... until I saw you wrote "sugar is pretty evil, so why do you use it?" or something along those lines... and I knew you were pretty darn hilarious! Here's to moderation! Great post 🙂

  8. I stopped eating Oats when I was diagnosed with Celiac Disease. Now that certified GF Oats are readily available, I have tried the Chocolate Peanut Butter recipe but I sub Almond Butter and the Strawberry Cream Cheese and I love them. I can't wait for fall to try the Pumpkin Spice.

    I do heat mine up. I can't imagine eating cold oatmeal. If the recipe has fruit in it, I do not heat to as high a temperature.

    So easy to make ahead and grab on the way out the door for work. Next step is to have my teenager give them a try.

  9. I was just looking for a quick recipe for oatmeal that was different and I landing on your AMAZING site! I can't believe how many wonderful ideas you had for cold oatmeal and then BAM...you threw in the link for the warm ones! I thank you for being so organized. The cold oatmeal reminds me of backpacking through Europe where we were on a shoestring budget and learned a trick from a fellow traveler to keep from feeling hungry overnight when we couldn't afford a decent meal. Oatmeal, a banana and milk cold for dinner which would expand and fill you up. Simple and good 🙂

  10. What kind of milk do you suggest? I am allergic to nuts so almond milk is out and I shouldn't really do soy....

  11. Thank you so much! I was researching anti-inflammatory foods and overnight oats kept popping up as something I should do. This post is so very helpful. Thank you!!
