Wake Up to the Best Overnight Steel Cut Oats!

A few years ago, I tried to make oatmeal overnight in my slow cooker and woke up to a pot of mush. After some trial and error (and many early mornings of testing), I finally cracked the code.

This Overnight Steel Cut Oats Recipe is the result of all that experimenting. Similar to overnight oats, it’s creamy but not soggy, hearty but not heavy, and the quinoa gives it the best nutty texture. I love that I can toss everything into the slow cooker at night and wake up to a warm breakfast the whole family devours with no morning rush required.

Why You’ll Love This Recipe

  • No morning prep. Toss it together in under 10 minutes at night.
  • Perfect texture. Creamy without turning mushy.
  • Customizable. So many topping options!
  • Feeds a crowd. Great for family breakfasts or meal prep.

Overnight Steel Cut Oats Recipe

Overnight Steel Cut Oats Recipe, made with oatmeal and quinoa in the slow cooker, is a healthy, hands-off breakfast. Just add fresh berries and a splash of milk to serve!

Cook Time: 8 hours
Total Time: 8 hours 15 minutes
Servings: 6 servings

Ingredients

  • 1-1/2 cups steel-cut oatmeal see note 1
  • 1/2 cup white quinoa
  • 5 cups unsweetened vanilla almond milk or water; I prefer almond milk!
  • 4 tablespoons brown sugar
  • 2 tablespoons maple syrup
  • 1/4 teaspoon salt
  • 1-1/2 teaspoons vanilla extract
  • Toppings as desired see note 2

Instructions 

  • Spray slow cooker generously with cooking spray or line with a slow cooker liner. In a mesh strainer, rinse quinoa under cold water for about 30 seconds to 1 minute. Let dry.
  • Combine steel-cut oats, rinsed quinoa, almond milk, brown sugar, maple syrup, salt, vanilla extract, and cinnamon (if desired) in the slow cooker.
  • Stir everything together, place the lid on the slow cooker, and set it to low for 1 hour. Then, without opening the slow cooker or disturbing it (otherwise heat escapes!), switch the dial to the warm setting. Allow to cook overnight for 8–9 hours (longer than that and it becomes mushy; see note 3).
  • Once you wake up, immediately turn it off and stir in the oats. They may still have some liquid, but it continues to soak in as they are served (I like them better with extra liquid rather than dry and mushy/gummy!) These oats are intended to be creamy.
  • Check the post above for more serving suggestions, but add your favorite toppings such as fresh fruit, an extra splash of milk, additional brown sugar, honey, or maple syrup, and a big scoop of nut butter (peanut butter, almond butter, etc.).
Final step! Please let us know how it was by leaving a review.

Recipe Notes

Note 1: Do not use regular old-fashioned, rolled, or quick oats—they won’t work. If you use instant or quick-cooking steel-cut oats, (Be sure to check the package—sometimes it’s hard to tell if they are instant steel-cut oats), it will be done in about 6–8 hours. For best results, I recommend regular steel-cut oatmeal.
Note 2: Optional toppings: 1/4 teaspoon ground cinnamon, fresh berries, a splash of milk, and additional sugar for topping.
Note 3: Different cooking options:
  • For morning brunch: Cook on low for 2-1/2 to 4 hours. I don’t recommend cooking overnight steel-cut oats on the high setting.
  • Overnight—with quick-cooking steel-cut oats: Cook on low for 30 minutes, then turn to warm for 6–7 hours.
  • Overnight—with regular steel-cut oats: Cook on low for 1 hour, then turn to warm for 8–9 hours.
  • Note that not all slow cookers cook the same. If your slow cooker has a tendency to cook quicker, it may be done sooner than the times indicated. If it is left in the slow cooker too long, it will likely become mushy and gummy. If your slow cooker cooks slower and oats/quinoa aren’t tender, turn the slow cooker back on to low for 30 or so minutes in the morning.
Storage: Store leftovers in an airtight container in the fridge for up to 4 days. Reheat with a splash of milk to loosen the texture before serving.

Overnight Steel Cut Oats Recipe Tips

  • Use a 6-quart slow cooker. Smaller ones haven’t been tested.
  • Grease or line well. Makes cleanup easier.
  • Keep the lid on. Don’t peek or it won’t cook right.
  • Use only steel-cut oats. Rolled or quick oats turn mushy.
  • Choose almond milk. Adds creaminess and won’t curdle overnight. Water works in a pinch, but skip cow’s milk.

    Has anyone tried this in a rice cooker? I have a zojirushi with a congee setting – might that work with the same water ratios?

          Divide everything made into six equal parts and each equal part is one serving 🙂

  3. susan says:

    can you use 2 cups of the oat and no quinoa? i would love to make some tonight but don’t have quinoa in the house! thanks! i’ve tried with old fashioned oats and it didn’t work well.

    1. chelseamessyapron says:

      Yes, unfortunately old fashioned oats cook way too quickly so I’ve never had luck with those either!

  4. Ann B. says:

    I made this for a weeknight overnight guest, and we both loved it! I set the slow cooker for 4 hours on low, and let it sit on warm for about another 3 1/2 hours, and it was great.

    1. chelseamessyapron says:

      So great to hear!! Thanks so much for your comment and leaving a review 🙂

  5. Heather says:

    I worry about the liners having BPA and heating them? I hate heating plastic 🙁

    1. Chelsea says:

      It’s not required to use plastic liners for this recipe; just a thought from another commenter.

  6. Sarah says:

    They make slow cooker liners that are disposable! Sort of like a self cleaning crockpot! I use it for lasagna!

    1. chelseamessyapron says:

      Genius!

      1. Erica says:

        You can find them near the tinfoil and storage bags at my grocery store. I know Target carries them as well, but they’re usually a $1 or so more expensive.

  7. Janie Lynn says:

    Oh . . . I love warm cereal in the morning, but especially when it’s healthy. I’ve never made quinoa before {come on! I had to learn how to say it first!}, but I love the variation of having it for breakfast. I’ve never seen that before. YUM! I’ll have to try making this and posting my version on my blog.

    From your whole foody!

  8. Kristi says:
