Stir together a few healthy ingredients in the crockpot, set it to cook overnight, and wake up to this nutritious Apple Steel Cut Oatmeal recipe to share with the whole family—babies and toddlers included. (With an easy stovetop option too.)

Easy Steel Cut Oatmeal Recipe
I’m always looking for new ways to make easy toddler breakfasts that the whole family will eat that don’t require a lot of work in the morning. With kids who get up at vastly different times (I have one early bird and one who sleeps and sleeps!), my own desire to drink a hot cup of coffee without reheating it over and overt, and juggling who knows what else each day, it’s breakfasts like this steel cut oats recipe.
You literally just need to stir the ingredients together (and okay, chop an apple), put the lid onto the slow cooker, and turn it on to cook. When you come down in the morning, it needs a quick stir but is otherwise ready to serve.
I’ve even been known to make this during the day, then stick it into an airtight container in the fridge for future mornings. It’s so nourishing and it tastes just sweet enough to appease the kids.
TIP: You can make this Sunday night and then warm it up throughout the week for quick and healthy meals. Or see the Notes for an easy stovetop version you can make right before you want to eat it.
Ingredients You Need
This steel cut oatmeal includes:

- Steel cut oats: Look for these in the cereal aisle in your supermarket. Steel cut oats are whole oat groats so they take longer to cook than rolled or instant oats (which are cut up).
- Applesauce: You can use homemade or store-bought applesauce.
- Apple: Any variety of apple works, though we prefer firmer cooking apples like Granny Smith or Pink Lady.
- Cinnamon
- Vanilla extract
- Milk: You can use dairy or nondairy milk.
Step-by-Step Instructions
The process of making this steel cut oatmeal recipe is so easy. Here’s a look at the steps involved. Scroll down to the bottom of the post for the full information.

- Chop your apple and stir together with the rest of the ingredients into a slow cooker.
- Cover and cook on low or high. (It’s okay if it sits on warm for a bit.)
- Remove cover and stir. Top with additional apples, a drizzle of honey or milk, or nuts, as desired.
TIP: I like to coat the inside of the slow cooker with butter to avoid sticking.

Can I make this Healthy Steel Cut Oatmeal on the stovetop?
Sure! Use the same ingredients and simmer over medium or medium-low for 25-35 minutes, stirring often (as the oats can stick to the bottom of the pan if you don’t stir regularly) or until soft. See the Notes at the bottom of the recipe for the full information.
Can I make this Apple Oatmeal dairy-free?
Absolutely! I like to use unsweetened soy or nut milk in this recipe and it works great. With all milks, you may see some separation when you take the lid off when the recipe is done, but just ignore it and give it a good stir and it’s ready to serve.
Is this a good baby oatmeal?
Yes! If you use unsweetened applesauce, there’s no added sugars and the texture is nicely smooth and soft for a baby. You may want to use a nondairy milk if your baby is under 1 and hasn’t started drinking dairy milk, but otherwise it’s an oatmeal that’s great for all ages.

How to Store
To store leftover steel cut oatmeal is to put them into an airtight container and store them in the fridge for up to 5 days. They will thicken slightly as they cool, so add a little water or milk when you heat them up and stir to create the desired consistency.
You can also stir cold oats into plain whole milk yogurt for another baby or toddler (or mama!) breakfast or snack. It’s sort of like overnight oats.
Best Tips for Success
- Add a little water or milk when you heat them up and stir to create the desired consistency.
- Use any apple you like such as Pink Lady, Jonathan, Cortland, or Granny Smith.
- Use unsweetened applesauce and unsweetened nondairy milk if your baby is under 1.
- To make this on the stovetop: Reduce the water by about a cup, and simmer over medium or medium-low for 25-35 minutes, stirring often (as the oats can stick to the bottom of the pan if you don’t stir regularly) or until soft.
- To make this gluten-free: Use certified gluten-free steel cut oats.
- Stir leftover cold oats into plain whole milk yogurt for another baby or toddler (or mama!) breakfast or snack.
