This slow cooker oatmeal recipe is perfect for those who want a warm, hearty breakfast ready as soon as they roll out of bed. It's simple, nutritious, and can be customized with your favorite toppings.
If you don't usually have steel-cut oats in your pantry, you'll need to pick some up at the supermarket. Unlike regular oats, steel-cut oats are less processed and have a chewier texture. You might also need to grab some vanilla extract if it's not a staple in your kitchen. Everything else should be fairly common.

Cinnamon: Provides a warm, spicy flavor that complements the oats.
Vanilla extract: Adds a sweet, aromatic flavor to the dish.

Alternative Ingredients
steel-cut oats - Substitute with rolled oats: Rolled oats cook faster and have a softer texture, but they can still be used in a slow cooker for a creamy oatmeal.
water - Substitute with almond milk: Almond milk adds a nutty flavor and creaminess, making the oatmeal richer without dairy.
milk - Substitute with coconut milk: Coconut milk provides a creamy texture and a subtle coconut flavor, which can add an exotic twist to the oatmeal.
cinnamon - Substitute with nutmeg: Nutmeg offers a warm, slightly sweet flavor that can complement the oatmeal similarly to cinnamon.
vanilla extract - Substitute with maple syrup: Maple syrup adds a natural sweetness and a hint of vanilla-like flavor, enhancing the overall taste of the oatmeal.
salt - Substitute with sea salt: Sea salt can be used in the same quantity and provides a slightly different mineral profile, which can subtly enhance the flavor.

How To Store or Freeze This Oatmeal
- Allow the oatmeal to cool to room temperature before storing. This helps prevent condensation, which can make the oatmeal watery.
- Transfer the oatmeal to airtight containers. For easy portioning, consider using individual serving-sized containers.
- Store the containers in the refrigerator for up to 5 days. This makes for a quick and convenient breakfast throughout the week.
- For longer storage, freeze the oatmeal. Use freezer-safe containers or resealable plastic bags. Lay the bags flat in the freezer to save space.
- When ready to eat, thaw the oatmeal in the refrigerator overnight. Reheat in the microwave or on the stovetop, adding a splash of milk or water to reach your desired consistency.
- Stir well after reheating to ensure a creamy texture. Add your favorite toppings such as fresh fruits, nuts, or a drizzle of honey for added flavor.
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 the bowl with a microwave-safe lid or plate. Heat on high for 1-2 minutes, stirring halfway through. Adjust the time as needed until the oatmeal is hot.
Oven Method: Preheat your oven to 350°F (175°C). Place the oatmeal in an oven-safe dish and cover with foil. Add a little milk or water to keep it moist. 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 the warm setting. Stir occasionally until it reaches the desired temperature.
Double Boiler Method: For a gentle reheating method, use a double boiler. Place the oatmeal in the top part of the double boiler and add a bit of milk or water. Heat over simmering water, stirring occasionally, until warmed through. This method prevents scorching and keeps the oatmeal creamy.
