We are big steel-cut oats fans, especially my youngest daughter. I make a batch every Sunday for her to eat all week for breakfast. She loves it with a swirl of maple syrup and likes to pile on the fruit and other toppings.
Most of the time, I’ll make this easy steel cut oats recipe on the stovetop. However, on busier meal prep days, I’ll break out the crockpot and let it do all the work.
Reasons You’ll Love This Slow Cooker Steel Cut Oats Recipe
- Simple pantry ingredients – To make a basic pot of steel-cut oats, all you need are oats and water. I’ll give some other variations below, but essentially, all that’s required are two ingredients.
- It’s an inexpensive, healthy breakfast – one serving of steel-cut oats is between .40 – .50 cents. And that’s for organic!
- You can easily double the recipe – It’s easy to make a large batch of steel-cut oatmeal to feed a crowd or freeze for later.
- Easiest breakfast meal prep recipe. Steel-cut oats can be made ahead for the week or frozen into portions for a quick healthy breakfast. I’ll give more meal prep tips below.
Ingredients
Steel-cut oats (also called Irish oats). These oats are less processed than rolled oats. Instead of being steam and rolled flat to speed up cooking time, steel-cut oats are the full groat cut in half with a blade. This is why steel-cut oats take longer to cook.
However, I prefer steel-cut oats over rolled when it comes to a warm bowl of oatmeal. Cooked steel cut oats are creamy and chewy with a little bit of bite to them.
Rolled oats often result in mushy oatmeal. However, rolled oats work better in other oatmeal recipes like overnight oats, baked oatmeal cups, or breakfast cookies.
Steel-cut oats are the perfect choice for cooking in a slow cooker.
Unsweetened almond milk – You can certainly make this crockpot steel cut oat recipe using just water, but I love to add unsweetened almond or coconut milk to the recipe for extra creaminess.
You could use dairy milk, but I like to keep this recipe vegan, so I use non-dairy milk instead.
Water – I use hot tap water when making this recipe.
Pure Vanilla Extract – A couple of teaspoons of vanilla extract infuses some extra flavor into the oatmeal. However, it is an optional ingredient, so you can leave it out of the recipe.
Cinnamon – This is another optional ingredient, but it does add a nice warm flavor to the oatmeal recipe.
Salt – A pinch of salt makes all of the other flavors pop.
FAQs
You can purchase steel-cut oats at any grocery store. My favorite brand is Bob’s Red Mill, but I’ve also used many excellent store brands.
You can find steel-cut oats in the cereal section or are often sold in bulk too.
I’m going to go against popular opinion here. No, I don’t think this recipe can cook for 8 hours or longer.
Over the last ten years, I’ve made steel cut oats in the crockpot many times, and the few times I tried to cook it overnight, it resulted in mush that stuck to the sides.
In my experience, the perfect cooking temperature and time is 4 hours on low and then 2 hours on warm.
I don’t recommend cooking it over 4 – 5 hours on low because it will burn and turn into mush. Also, I never recommend cooking slow cooker steel-cut oatmeal on the high setting.
Of course, that’s been my experience using my slow cooker.
When cooking steel cut oats on the stovetop or in the slow cooker, you’ll need 4 cups of water for 1 cup of oats.
Double both when you want to make a larger batch.
I like to use non-dairy milk to add creaminess but cooking steel-cut oatmeal using just water will work fine.
Toasting the oats is an optional step, so you don’t need to do it. However, toasting the oats adds a delicious nutty flavor, so I highly recommend it if you have the time.
I’ve been preparing slow cooker steel-cut oatmeal in the ten years I’ve never rinsed the oats. So, from my experience, no, you don’t.

Cooking Notes
To prevent sticking, spray the insert liberally with cooking spray. You can also use a slow cooker liner.
Sweeten the cooked oatmeal afterward. You might notice there’s no sugar in this recipe. I do this on purpose.
I find it easier to control the calories when I add the sweetener after it’s cooked. Also, we can all control the sweetness to our tastes.
Topping ideas to sweeten oatmeal:
- Pure maple syrup
- Brown sugar
- Coconut palm sugar
- Jam or jelly
- Stevia or monk fruit
- Chocolate chips
- Banana
Add other toppings. You can enjoy a simple bowl of oatmeal or get creative and build the perfect bowl of oatmeal with your favorite toppings.
Keep in mind that if you’re trying to lose weight, then choose healthier toppings and measure out everything before adding it to the oatmeal. Even healthy calories can add up.
More topping ideas for oatmeal:
- Yogurt
- Nuts
- Berries

- Dried fruit

You can even make savory oatmeal by adding eggs and sauteed vegetables.
