This recipe is perfect for busy mornings, as you can prepare it the night before and wake up to a delicious, ready-to-eat breakfast. The combination of steel-cut oats, milk, and cinnamon creates a creamy and flavorful dish that will keep you satisfied for hours.
If you don't typically have steel-cut oats in your pantry, you might need to pick some up at the supermarket. Unlike regular rolled oats, steel-cut oats are less processed and have a chewier texture.

How to Store / Freeze Your Oatmeal
Allow the oatmeal to cool to room temperature before storing. This helps prevent condensation, which can make the oatmeal soggy.
Transfer the oatmeal into airtight containers. Use individual portion sizes for convenience, especially if you plan to grab-and-go during busy mornings.
Store the containers in the refrigerator for up to 5 days. This ensures the oatmeal stays fresh and maintains its texture.
For longer storage, freeze the oatmeal. Use freezer-safe containers or zip-top bags. Lay the bags flat in the freezer to save space and allow for quicker thawing.
Label each container or bag with the date. This helps you keep track of how long the oatmeal has been stored and ensures you consume it while it's still at its best quality.
To reheat refrigerated oatmeal, transfer a portion to a microwave-safe bowl. Add a splash of milk or water to loosen the consistency. Microwave on high for 1-2 minutes, stirring halfway through.
For frozen oatmeal, thaw overnight in the refrigerator or use the defrost setting on your microwave. Once thawed, reheat as you would refrigerated oatmeal.
Enhance the reheated oatmeal with fresh toppings like berries, nuts, or a drizzle of honey. This adds a burst of flavor and texture, making each bowl feel freshly made.
How to Reheat Leftovers
Stovetop Method: Place the leftover oatmeal in a saucepan. Add a splash of milk or water to loosen it up. Heat over medium-low, stirring occasionally, until warmed through. This method helps maintain the creamy texture.
Microwave Method: Transfer the oatmeal to a microwave-safe bowl. Add a bit of milk or water and cover with a microwave-safe lid or plate. Heat on high for 1-2 minutes, stirring halfway through. Continue heating in 30-second intervals if needed, until hot.
Oven Method: Preheat your oven to 350°F (175°C). Spread the oatmeal evenly in an oven-safe dish. Add a little milk or water to keep it moist. Cover with foil and bake for about 15-20 minutes, or until heated through.
Slow Cooker Method: If you have time, you can reheat the oatmeal in the slow cooker. Add a bit of milk or water to the oatmeal and set the slow cooker to low. Heat for 1-2 hours, stirring occasionally, until warm.
Double Boiler Method: Place the oatmeal in a heatproof bowl. Set the bowl over a pot of simmering water, making sure the bottom of the bowl doesn't touch the water. Stir occasionally until the oatmeal is heated through. This gentle method helps prevent scorching.
