Make-Ahead Freezer Steel Cut Oats is an easy recipe for frozen steel cut oatmeal pucks that you can quickly reheat for a healthy breakfast on busy mornings!
Lightly grease 12 cups of a muffin tin with cooking spray, butter, or coconut oil; set aside.
In a large pot set over medium-high heat, combine the milk, water, and salt. Bring to a rolling boil and stir in the oats. Reduce the heat to a low simmer and cook for 30 minutes or until the oats are tender and the liquid is absorbed, stirring frequently.
Remove the pot from the heat and stir in the maple syrup/honey, cinnamon, and vanilla. Allow the oatmeal to thicken for 5 minutes.
Evenly divide the oatmeal between the prepared muffin cups. Place the muffin pan in the freezer for several hours or until the oatmeal is frozen solid.
Use a butter knife to loosen each frozen oatmeal puck from the pan and then pop it out. Place the oatmeal in a freezer-thickness plastic baggie and return to the freezer for up to 3 months.
When ready to enjoy a bowl of steel cut oatmeal, place one or two frozen oatmeal pucks in a bowl. Microwave on high for 1 ½ to 3 total minutes (depending on the strength of your microwave), stirring halfway through, or until the oatmeal is hot.
