A favorite at my house - these freezer steel-cut oats are a great way to freeze a bunch of high-quality oatmeal and then reheat it quickly when you need a fast breakfast!
Bring the water to a slight simmer in a medium to large pot (at least 2 1/2 quarts). Add a pinch of salt to the water.
Stir in the steel cut oats and simmer the oats on low heat until they thicken and absorb the water. Stir occasionally so the oatmeal doesn't stick at all to the pot.
After 25-30 minutes, the oats should be tender and most of the water absorbed. Remove the pot from the heat, cover, and let rest for a few minutes to cool.
When ready to freeze, measure out about 1/2-cup to 3/4 cup of oatmeal and place on a baking sheet lined with parchment paper.
Place baking sheet in a freezer to freeze the oatmeal completely and then transfer the oatmeal pucks to an airtight container to store in the freezer for up to three months.
Reheating the Oatmeal
Place one oatmeal puck in a microwave-safe bowl with 1/4 cup water. Microwave on high for 2 1/2 minutes.
Top hot oatmeal with toppings of your choice and serve immediately!
