While I love overnight oats on busy mornings, I also enjoy a delicious bowl of oatmeal that I can assemble fast using any oats I have around by microwaving old-fashioned oats or cooking this recipe even faster using quick oats and still making the most of all the oatmeal health benefits.
Since everyone in my family loves different flavors, we customize our bowls with our favorite toppings or use my homemade instant oatmeal recipes to satisfy everyone’s cravings. So simple and so good!
Ingredients
Oats to water ratio is key for epic quick oats in the microwave. But before we jump to the amounts, here’s what you need to know about the ingredients:
- Quick oats: the thin, small flakes, also known as instant oats.
- Brown sugar: optional for sweetness.
- Cinnamon: also optional but oh so delish!
- Salt: a pinch is enough to make oatmeal tastier.
- Milk or water: use only water or dilute milk with water. If you only use milk, the oatmeal will be too thick.
- Toppings: your favorites or some of the tasty ones I’ll share below!

While you can microwave quick oats using water or milk, oats with water are pretty plain, and when you use milk, it makes the oatmeal thicker and creamier, and it also adds flavor. In the end, you pick!
How to Microwave Quick Oats
Making quick oats in the microwave is super simple, and it won’t be any mess if you follow these steps and tips:

To keep oatmeal from overflowing, use a bigger bowl than you think you need to combine quick oats and liquid. - Microwave

Ratio of Oats to Water
When cooking quick oats in the microwave, the optimal ratio is 2:1 quick oats to water, which means 1 cup of water for each ½ cup of oats. This same ratio applies when using milk.
| Servings | Oats | Water |
|---|---|---|
| 1 | ½ cup | 1 cup |
| 2 | 1 cup | 2 cups |
| 3 | 1 ½ cups | 3 cups |
| 4 | 2 cups | 4 cups |

Microwave overflows are the absolute worst to clean up in the morning. Your advice about the bowl size actually helps since I usually just guess. Adding fresh fruit makes such a huge difference for breakfast.
