How to Store / Freeze This Recipe
Allow the slow cooker oats to cool completely before storing. This prevents condensation from forming inside the container, which can make the oats soggy.
Transfer the cooled oats into an airtight container. Glass containers with tight-fitting lids are ideal for maintaining freshness and preventing any unwanted odors from seeping in.
Store the container in the refrigerator. The oats will keep well for up to 5 days, making it a perfect option for meal prep.
For longer storage, portion the oats into individual servings. Use freezer-safe containers or resealable plastic bags, ensuring you leave some space at the top as the oats will expand slightly when frozen.
Label each container or bag with the date and contents. This helps you keep track of how long the oats have been stored and ensures you use the oldest batches first.
To reheat refrigerated oats, transfer a portion to a microwave-safe bowl. Add a splash of milk or water to loosen the consistency, then microwave on high for 1-2 minutes, stirring halfway through.
For frozen oats, thaw overnight in the refrigerator or use the defrost setting on your microwave. Once thawed, reheat as you would refrigerated oats, adding milk or water as needed.
Customize your reheated oats with your favorite toppings. Fresh berries, nuts, honey, or a dollop of yogurt can elevate your breakfast to a gourmet experience.
If you prefer a stovetop method, transfer the oats to a saucepan, add a bit of milk or water, and heat over medium-low, stirring occasionally until warmed through.
Always ensure the oats are heated to a safe temperature before consuming, especially if they have been stored for several days.
How to Reheat Leftovers
Stovetop Method: Place the leftover oats in a saucepan. Add a splash of water or milk to loosen them up. Heat over medium-low, stirring occasionally, until warmed through. This method helps maintain the creamy texture.
Microwave Method: Transfer the oats to a microwave-safe bowl. Add a bit of water or milk to prevent them from drying out. Microwave on high for 1-2 minutes, stirring halfway through. Adjust the time based on your microwave's power.
Oven Method: Preheat your oven to 350°F (175°C). Spread the oats in an oven-safe dish. Cover with foil to retain moisture. Bake for about 15-20 minutes or until heated through. This method is great if you're reheating a large batch.
Slow Cooker Method: If you have time, you can reheat the oats in the slow cooker. Add a bit of water or milk to the oats and set the slow cooker to low. Heat for about an hour, stirring occasionally. This method is perfect for maintaining the original slow-cooked flavor.
Double Boiler Method: For a gentle reheating, use a double boiler. Place the oats in the top part of the double boiler and add some water or milk. Heat over simmering water, stirring occasionally, until warmed through. This method prevents scorching and keeps the oats creamy.
