Sugar-free slow cooker steel-cut oatmeal

Slow cooker apple cinnamon oatmeal

Assemble this oatmeal recipe before bed and wake up to the smell of cinnamon wafting through the house. You need to use a slow-cooker for this recipe and hunt down steel-cut oats, but it’s worth the trouble.

Steel-cut oats are the original oat groat that is sliced into several pieces instead of rolled. They aren’t as popular as rolled oats, because steel-cut oats take about ½ an hour to cook on the stovetop (you’ll use a slow cooker for this recipe though, so cooking time won’t matter!)

Steel-cut oats can be found in most grocery stores. However, they’re often sold in small packages and are more expensive than other kinds of oats. If you like this recipe, it’s worth finding a place that sells them in larger quantities at a more reasonable price! For example, my local Costco sells a 10-pound package for around $10.

Recipe Notes

Try using a pear instead of an apple, or add other dried fruit. Fresh berries (e.g. blueberries, strawberries, raspberries) tend to disintegrate in the slow cooker, so add them at serving time.
