Add the oats, milk (or water), and salt in a medium saucepan over medium-high heat. Bring the mixture to a simmer, stirring occasionally, and once it simmers, reduce the heat to the lowest setting.
Cook the oatmeal for 5 minutes, stirring from time to time, until the desired consistency is reached. Turn off the heat. For a thicker oatmeal texture, cover and let the oats sit in the saucepan for 3 more minutes.
Serve:
Divide the oatmeal into bowls and top it with your favorite toppings.
Notes
Using milk instead of water will yield a thicker and creamier bowl of oats.
