My typical morning breakfast: steel cut oats topped with flax seed, blueberries and a sprinkling of walnuts. Sometimes I make up batches of Overnight Oatmeal in a Jar and occasionally I grab a Banana Oatmeal Cookie on the run. But, one way or another oatmeal is usually involved.
On the stove-top, it takes about 20 minutes to cook steel cut oats (a.k.a. Irish oatmeal.) In the morning, when you're in a hurry, minutes can seem like hours. But, this breakfast is totally worth it. These heartier oats stick to your insides and keep you going strong all morning long (at least, according to my mom!)
Solution: You can have this hearty breakfast and still have time for an extra cup of coffee because these oats cook beautifully overnight in a crock-pot. 🙂

What are steel cut oats?
Oats get a different name depending upon how they are processed. They all start as oat groats (unprocessed grains) and are usually roasted. Steel cut oats are chopped into small pieces with a steel blade and have the least amount of processing of the different varieties. In comparison, rolled oats are steamed and flattened.
As you probably guessed, the minimal processing means that steel cut oats are widely considered the most nutritious and healthy of the different types.
Their flavor is nutty and slightly chewy. The liquid they absorb as they cook is what softens them.
You'll also find quick cooking steel cut oats on the market. These are processed the same way but are chopped more finely than the regular variety. As a result, they cook more quickly!
Warning: Don't use quick cooking steel cut oats in this overnight slow cooker recipe!

Ingredients and Variations
I use a cute little 2 quart crock-pot to make 4 servings of oatmeal. (A larger appliance could be used to double or triple this recipe.)
Four servings works out nicely at our house. Hopefully, my daughters or hubby will enjoy one. Otherwise, I make ahead breakfast bowls for the rest of the week to reheat in the microwave.
For four servings, mix 1 cup of steel cut oats with 4 cups of water. The stove-top directions are right there on the package and I don't vary a thing. I just add everything to the crock.
I use water because I have family members with food allergies. However, other liquids, such as almond milk, could be used instead.
This simple recipe calls for vanilla and cinnamon, which enables you to cut down on the amount of sweetener needed (in my humble opinion.) You can sweeten with a ¼ cup of brown sugar while it is cooking too. (I didn't.) Instead, I've been adding a dropper of stevia sweetener. (Yes!)

How long do you cook steel cut oats in a crockpot?
Cook on low heat for 6-8 hours. I often cook it for 8 hours (to make it through the night.) If you don't like oatmeal on the firm side or find that it sticks to the sides of the crock-pot, then add a little extra liquid at the start. Or, stir in some water or milk after they are cooked.
At 8 hours, you'll likely start to experience browning around the edges. I use a spoon to scrape it off.
TIP: Use a slow cooker liner to make clean-up a breeze.

Topping Ideas for Oatmeal
Oatmeal doesn't have to be boring! Cover it with a variety of toppings. Here are some ideas to get you started.
- Flax seed
- Chia seeds
- Honey
- Maple syrup
- Nut butters
- Date paste
- Fresh fruit, such as apples or berries
- Dried Fruit
- Fruit jams (such as blueberry compote or apple butter)
- Chopped Nuts
- Chocolate Chips
- Coconut
- Granola

How long can you keep oats in the fridge?
5-7 days is a good rule of thumb for keeping oats in the refrigerator. Toppings that will stay fresh (i.e., flax seed, chia seeds, dried fruit) can be added beforehand. Or, top it off when you are ready to eat.
TIP: It's easier to stir in toppings, like flaxseed and nut butters, when it's warm!
How to Reheat Steel Cut Oats in the Microwave
Stir in a little water or milk (about 1 Tablespoon) if you don't like your oats firm. Microwave the container on high in 30 second increments until the steel cut oatmeal reaches the desired temperature and consistency. Add any topping as you normally would and enjoy!

Loved it …use raw honey with the cinnamon for sweetness and to get one of natures best combinations for your health If I were to cheat I would add more water
Marjory Pilley says
I’m so happy you enjoyed it!
Katherine Groboski says
My favorite recipe for steel cut oats!
Victoria says
I typically make an apple pie steelcut oat so I was on the lookout for an easier recipe. Thanks for sharing!!
Saw some interesting questions. I use a large oval crockpot for 2 to 4 people. If you want to simplify clean up, add your ingredients to a glass ungreased cooking dish that you can place in the crockpot. Add water to the bottom of crock, avoid water flow into dish with ingredients so about 1/3 up the dish. You'll thank me the next day when cleaning is simply soak and wash verses scrubbing.
I use almond milk, unless I'm low, then I may mix with water.
Marjory Pilley says
Thanks so much for sharing this super helpful tip!
Brenda C says
I had burnt oatmeal on the bottom. Not enough liquid?
Marjory Pilley says
Hi! You may need more liquid and possibly reduce the time.
Lu says
Instead of 4 cups of water, I use 2 cups of water and 2 cups of almond milk, add a 1/4 cup of butter cut up in cubes, and substitute 1/4 cup of brown sugar instead of sweetener and sprinkle a little of ground cloves and nutmeg and use all of other ingredients as shown and place in the crock pot, stir good and cook overnight on low. TIP** Use the slow cook liners for the crockpot as it cuts down on the cleanup.
marie williams says
Love it. It needed a little less than 7 or 8 hrs. I'm trying for 6 & 1/2 hrs. this time.
Thanks!
Riya Agrawal says
Thanks for sharing the recipe. Will definitely try with True Elements steel cut oats as they are really good and a clean label food brand. You can also give it a try!
Jenn says
Hi, I’m wondering if I could cook the recipe which I’ve halved for just myself on high in the small crockpot for 2 hours? I’ve cooked half a batch on low for 3-4 hours and it comes out perfect. Just trying to see what works when I have less time and want to use the crockpot. Thank you
Marjory Pilley says
I've never tried that, but cooking on high should definitely shorten the time. And, cooking on high often cuts the cook time in half, so definitely worth a try! I'd love to know how it works out.
Maggie Mentel says
Mine did not come out right again. I used this recipe but it produced a thick coat of oats in the crockpot liner that was inedible. It also had too much liquid because in the morning there was an inch of "soup" on the top. I have tried two different crockpots and I always get burned oats on the bottom and soup on the top. What am I doing wrong?
Marjory Pilley says
I'm so sorry the oats didn't cook properly. A few things to consider while trouble shooting. First, the crock-pot should be small unless you're doing a much larger batch. Second, be sure the steel cut oats have not expired. Third, be sure to stir them in the pot before putting the lid on. Fourth, you may want to use less liquid. Start by using about 1/4 cup less. Fifth, it sounds like the cook time could be a little long. I have 2 slow cookers and one definitely cooks faster than the other. I do get a little crust at the bottom, particularly if I let I let it go overnight which ends up being more like 8-9 hours of cook time. Some people grease the pot to make clean-up easier. I've never experienced an inch of liquid at the top. Does that remain after you stir the oatmeal? I realize all of these issues don't apply, but thought I would give as much info as possible. I hope it helps.
Crispy says
Never eaten not made before. Followed recipe exactly and used my Mini IP. Came out creamy and very tasty. Topped with fresh blueberries & sliced almonds and served with touch of brown sugar and while milk. Taste: #9/10. Will be a regular in my recipe repertoire.
PeggyP says
Thank you Marjory for this lovely oats recipe.
I followed your recipe and added walnuts, coconut oil instead of butter & coconut nectar instead of sugar to cook. And serve with dried mixed berries toppings. 👍👍👍
Rose says
Can you use steel cut oaks in the overnight mason jar oatmeal recipe?
Marjory says
Yes! You'll want to be sure that they soak in the liquid for about 10 hours...and can even go for a couple of days. They will continue to absorb liquid becoming firmer on the 2nd and 3rd day.
Angela says
I’ve made oats this way in the past but never added anything but the sc oats and water. Now I’m anxious to make it using your recipe! I have a ski weekend coming up with a group and I’m responsible for breakfast one morning for 14 people. Could I double (or triple?) this recipe in a 3.5 quart crock pot? Recommendations for making this for a crowd (away from home) would be appreciated. Thanks!
Marjory says
Definitely double or triple the recipe and use a large slow cooker. Fill the slow cooker at least halfway full (and up to 2/3 full)! It's a great way to feed a crowd because you can put out a toppings bar with fresh and/or dried options for everyone to add.
Angela says
Thank you!!
Jodie says
If you double the recipe, do you need to cook it longer?
Marjory Pilley says
For this recipe, you would not need to cook it longer!
petrichor says
Try using apple juice instead of water, and add all kinds of chopped dried fruit (raisins, cranberries, blue berries, apricots) and cinnamon and/or nutmeg if you cook it slow overnight, the house smells wonderful in the morning. At the table only add a little salt and a pat of butter (+ a dash of Scotch whiskey for "Scotch Porridge"). You will be addicted to this "Gourmet Oatmeal".
