Hearty Make-Ahead Steel-Cut Oats Recipe
Yes, you can make overnight oats from steel-cut oats! The only catch? Steel-cut oats won’t soften if you simply soak them in the fridge overnight like rolled oats. Instead, I’m going to show you how to quickly cook the raw oats before refrigerating. It helps them soften up and also infuses this overnight steel-cut oats recipe with delicious cinnamon-vanilla flavor.
There are so many ways to turn a serving of morning oatmeal into something delicious. From baked oatmeal and oatmeal cups to tasty mix-ins and toppings, you’re going to love it!
Why Make Overnight Steel-Cut Oats?
- A hearty breakfast. Any oats make a satisfying breakfast, and steel-cut oats are extra chewy and filling. These are a great meal-prep breakfast since they store in the fridge for days.
- An easy recipe using steel-cut oats. Raw steel-cut oats are generally too dense and hard for baking or using as a straight substitute for rolled oats. Turning them into overnight oats is a wonderful way to use up a package of steel-cut oats in the pantry!
- Oatmeal without the work. There’s no hovering over a hot stove, and prepping this steel-cut oatmeal the night before means waking up to an easy breakfast that’s ready to eat.
- Customizable. Try this recipe with extras like chopped nuts, chocolate chips, fresh fruit, dried fruit, and different flavors.
You’ll Need These Ingredients
- Oats – You’ll find steel-cut oats in the dry goods aisle alongside rolled oats and quick oats.
- Milk – Any kind, dairy or non-dairy. For creamier, extra-rich overnight oats, try a variation with canned coconut milk.
- Vanilla and Cinnamon – I recommend using pure vanilla extract, but the ground cinnamon is optional. You could leave it out or replace it with nutmeg, cardamom, or a pie spice blend if you’d like.
Steel-Cut vs. Rolled Oats
Steel-cut oats are whole oats that have been roughly chopped. They’re a bit like the chunkier, less-processed relatives of rolled oats and quick oats, and they take longer to cook and soften. For this reason, overnight steel-cut oats are heartier and chewier than classic oats.
Optional Toppings
- Fresh pitted cherries
- Strawberries, blueberries, or raspberries
- Sliced ripe bananas
- Drizzle of nut butter
- Maple syrup or honey
- Chocolate chips
Tips for the Best Steel-Cut Oatmeal
- Watch while the oats cook. Keep an eye on your steel cut oats while they cook on the stove. They can boil over quickly!
- Stir well. For the creamiest texture, give your overnight oats a good stir before serving.
- Loosen the oats. If you notice they’ve become too thick, add a splash of milk.
- Boost the flavors. While cinnamon is optional, don’t skip the vanilla! You can also add a pinch of salt to enhance the flavors.
Variations
- Protein overnight oats. Add your favorite protein powder to make a variation of overnight protein oatmeal with steel-cut oats.
- Chocolate. Stir cocoa powder into the oats for a chocolate version.
- Mix-ins. Just about any of the topping ideas listed in the Toppings suggestions double as delicious mix-ins for these overnight oats! Stir in nuts, chocolate, fruit (try apple oatmeal in the fall), or nut butter.
