What Are Steel Cut Oats?

While most people are familiar with rolled oats and quick oats, there seems to be a lot of speculation surrounding steel cut oats. What are steel cut oats? Are they good for you? For starters, steel cut oats are very good for you! Much like their counterparts, these oats are loaded with fiber, vitamins, and minerals.

All oats start out the same: as oat groats. These are the whole and unbroken forms of the grain. The main difference between the types of oats is the way they are all processed. Unlike rolled and quick oats that are rolled flat and steamed, steel cut oats are simply oat groats that are chopped into smaller pieces.

This way of processing results in oats that are chewier in texture and take longer to cook than other types of oats. Steel cut oats are slightly higher in fiber and have a lower glycemic index than rolled and quick oats. Because they take longer to cook, steel cut oats work great in slow cooker recipes like this one!

Key Ingredients

You will need the following key ingredients to make this delicious slow cooker recipe:

  • Steel cut oats: Because these are the closest type of oats to the unprocessed version, they take longer to cook and are therefore perfect for a slow cooker recipe like this one.
  • Almond milk: This recipe calls for unsweetened plain almond milk, but feel free to use vanilla almond milk or any other type of milk you prefer.
  • Water: I like to use equal parts water and almond milk, but feel free to swap out the combo for all of either one of them.
  • Bananas: Who needs sugar when you have bananas? When choosing your bananas, keep in mind that the riper bananas are sweeter. If you like your oatmeal on the sweeter side, opt for brown bananas!
  • Flaxseed meal: The nutty flavor of this superfood beautifully complements the nutty flavor of the steel cut oats. It also adds a ton of beneficial nutrients.
  • Chia seeds: These tiny seeds are bursting with nutrients, fiber, and heart-healthy fats. They also soak up some of the liquid, ensuring that the oatmeal gets nice and thick.
  • Vanilla extract: This ingredient not only adds great flavor on its own, but it also enhances the rest of the delicious flavors of our slow cooker oatmeal.
  • Spices: A little cinnamon and salt go a long way here, trust me! The cinnamon adds a delicious warm flavor and the salt enhances the flavors of our other ingredients.

Slow Cooker Steel Cut Oatmeal Cooking Tips

Here are some of my top tips to help you make this recipe:

  • Do not swap out the steel cut oats for another type of oats. For this recipe, it’s important to use steel cut oats or you will likely wind up with super mushy oats!
  • Make sure to spray the slow cooker with cooking spray so that it’s completely covered to ensure that the oatmeal doesn’t stick.
  • To prevent burning and ensure even cooking throughout, I recommend stirring the oatmeal every few hours.

How to Store Cooked Steel Cut Oatmeal

If you wind up with leftover oatmeal, you can easily store it for later. Before storing this dish, you will first need to let it cool to room temperature. Once it’s cooled, transfer the oatmeal to airtight storage bags or containers and store it as follows:

  • In the fridge for up to 4-5 days.
  • In the freezer for up to 3 months.

Frequently Asked Questions

Below you will find the answers to some of the most frequently asked questions about this dish:

Steel cut oats are very similar in nutrition to rolled oats. However, they do contain slightly more fiber and are lower on the glycemic index than rolled oats, making them just a bit healthier. Regardless, both types of oats are excellent additions to a healthy diet!

Absolutely! To freeze oatmeal, you will first need to allow it to cool down to room temperature. Once it’s cooled, transfer the oatmeal to airtight ziploc bags or storage containers and freeze it for up to 3 months.

You can cook this recipe in the slow cooker on Low for 7-8 hours or on High for 4 hours. I recommend choosing the Low setting for the best results, but either option will work.

Unfortunately, this recipe only works with steel-cut oats. Regular rolled oats become very soft and mushy in the slow cooker.

This recipe will turn out great without the bananas, but it won't be as sweet. You can add maple syrup or honey to taste. Additionally you could swap in applesauce, sweet potato puree, butternut squash puree, pumpkin, or another fruit puree.
