In a medium saucepan, bring water to a boil, then add oats.
Lower heat and simmer uncovered for 10 minutes, or longer for creamier oatmeal.
Stir and serve hot, as is, or with toppings of your choice.
Refrigerate leftovers within 2 hours.
Topping ideas: fresh, frozen or dried fruit; milk or yogurt; chopped nuts or seeds; cinnamon or other spices. Savory toppings include chopped vegetables and grated cheese.
For even creamier oatmeal, stir in more water as you cook it longer.
Cooked oatmeal can be stored in the refrigerator for 3 to 4 days or in the freezer for up to 3 months.
After boiling the water, simmer oatmeal in an electric skillet (Warm to 200 degrees F) or microwave on high for 2 1/2 to 3 minutes. You can also make the oatmeal in a rice cooker on the white rice setting.
