🥛 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. Stupid question...when I take the jar out of the fridge to bring with me to work, should I stir it or just wait til I get to work to open the jar?

  2. Hi! I love this article. I just made the pumpkin overnight oats, and I only did a teaspoon of honey. Does adding more honey/maple syrup really affect the sweetness? I thought they would be sweeter but I'm guessing bc I didn't put more honey in that that's why they weren't that sweet. Thoughts?

  3. Your overnight oats look amazing!
    I've tried making my overnight oat and the taste was not so good. The texture was greasy and even far from creamy texture.
    I didn't use yoghurt, but only milk instead and I didn't use old fashion oat, but instant oat.
    What's so different ?

  4. I'm a new visitor to your blog and I've made three of the recipes : carrot cake, strawberry cheesecake and banana with chocolate chips. All three were wonderful and I made the carrot cake and banana with steel-cut oats, which added a nice chewy texture. Could this be make with quinoa to reduce the carbs and increase the protein?

  5. Thai ginger:

    Crushed Peanuts
    Coconut cream
    Dates
    Fresh ginger

    Also dates are a great way to naturally sweeten!

  6. Thank you! I don't know how I missed the Overnight Oats trend, but after having some on a trip to Portland (a healthy, quick, protein filled breakfast), I Googled and found your recipes! Easy, healthy and yum, yum, yummy!

  7. Is it possible for a girl to eat the whole portion at once? And isnt that too many calories for breaky? Thanks so much for the answer ? looking forward to trying all of them

  8. I am so excited to try these! I've been wanting to try overnight oats for awhile now and these sound easy and great!

    1. Oats are naturally gluten free but they're processed in factories that are contaminated with gluten.

      That wouldn't bother your average person but someone with a gluten allergy/sensitivity can't risk it.

      It's like people with nut allergies not being able to have candies that were created in factories that make products with nuts.

  9. Is refrigeration mandatory or can I simply leave the jar on the table overnight? I usually prefer my breakfast warm or room temperature.
    Thank you for the recipes

  10. Ooooh girl!! Spot on!! Took one to work yesterday morning and all is right with the world! Had to make an extra one for my Dad to have this morning!! #itscontagious

    Thank you!!

  11. Cassie, I was born and raised in Northern Indiana, South Bend.! Say, do you have the nutritional info for these recipes? They all look delicious. However, I need to know the calories, carbs, protein and fat content for each batch. I'd like to know so I can modify some of the ingredients to suit my nutritional needs. Thanks!

    1. I would also like to know. I'd like to start eating "better", so I'm looking for some ideas. I'm one of those difficult people that has a hard time with anything that doesn't taste good, even if it's good for you?. So, these recipes sound great! Just need to know if they'd be good for a "diet".

  12. I love these recipes. But do you realize your page is routinely serving up ads that routinely navigate the browser away from this page automatically? They don't even leave a choice to hit back or close the ad. I've copied the recipe to a text file just so I don't have to keep closing and reopening the page due to the ads hijacking my browser.

    1. Oh no! That's definitely not supposed to be happening. I'm so sorry about that! Next time it happens, can you copy the URL and email it to me at cassie@backtoherroots.com? That's the only way my ad managers can squash those super annoying ads. Again, I'm so sorry!

  13. HI Cassie... thanks for the awesome recipes. Since we're moving into the fall, do you think frozen fruit would work for the tropical recipe?
