Oatmeal isn't difficult to cook, but if your mornings are jam-packed without a second to spare, you can cook up a big batch of oatmeal ahead of time and freeze serving-sized portions for a healthy breakfast ready to eat in minutes. You can freeze any type of oatmeal, including instant, old-fashioned, or steel-cut oats. Freeze plain, unadorned oatmeal and add fruit and nuts later, or include your favorite toppings in the frozen packets for extra-easy preparation.

Cook a batch of oatmeal according to the directions on the package. Keep in mind that steel cut oatmeal takes longer to cook -- usually about 25 to 30 minutes.

Stir in your choice of mix-ins such as nuts, seeds or dried fruit, if desired.

Allow the oatmeal to cool, then transfer the cereal to a nonstick muffin pan. For smaller servings, spoon the cereal into ice cube trays lined with plastic wrap.

Cover the pans loosely with plastic wrap, then place the pan or trays in the freezer. When the oatmeal is frozen solid, remove the cereal from the pan or tray and place serving-size portions in plastic freezer bags. Two or three muffin cups is usually enough oatmeal for one adult serving.

Put the frozen oatmeal in microwave-safe bowls and heat it for 1 to 2 minutes, then add toppings such as milk or brown sugar.

Use the frozen oatmeal within three months for the best quality.


  • If you want to freeze uncooked oatmeal, place the oats in a sturdy, airtight container. Oatmeal retains its quality indefinitely if your freezer is set at zero degrees Fahrenheit or lower.
