In a 2-quart saucepan combine the steel cut oats, water, milk, and salt. Bring the liquid to a boil over high heat on the stove top.
Once the liquid it boiling, set a timer for 2 minutes. The boiling liquid may start to rise up towards the top of your saucepan, if this happens lower the heat until the liquid lowers. Stir often so the oats won't stick to the bottom of the pan.
When the timer goes off, remove the pan from the heat and set it aside to cool for 20 minutes. (This way, you won't add boiling-hot oats to glass jars and risk them breaking.) The oats will continue absorbing the liquid as they cool.
Once the oats have cooled, transfer them to individual storage jars with lids. One cup of dry oats makes 3 hearty servings cooked. Store the oats overnight in the fridge to continue softening.
When you're ready to eat, grab a jar of oats from the fridge and add your favorite toppings. These can be enjoyed warm or cold. Heat them up on the stovetop with an extra splash of milk, or microwave in a heat-safe bowl for 60 to 90 seconds. Oats will keep well in the fridge for up to 5 days.
