Microwave Oatmeal Recipe

We love oatmeal for breakfast and have it several times a week. But since we started making oatmeal in the microwave, there’s no turning back! Wow, the results are fantastic. After you understand your specific microwave wattage and power, you’ll be making perfect oatmeal again and again. The old fashioned rolled oats cook plump and perfect. It’s so delicious and fluffy, not mushy when you’re using whole oats. This recipe does not work for quick oats because those have a tendency to come out mushy.

Breakfast just got easier & more delicious. Microwaving old-fashioned oats for a quick breakfast is super easy and tastes great. No extra pans to wash and the texture is perfect.

How to Cook Oatmeal in Microwave

  • Make sure you’re using old fashioned rolled oats or whole oats. We love the Bob’s Red Mill brand of Old Fashioned Rolled Oats.
  • Every microwave has a different power level, so make sure your microwave is set at the default “high” power.
  • Don’t forget to add a bit of salt. This really brings out the flavor of the oatmeal.
  • Use a bowl that is a little deeper or bigger than the amount of oatmeal you are cooking. This will allow more room for the oatmeal to expand and become fluffy.
  • Add a little milk at the end of the oatmeal is still a little dry. Leaving oatmeal covered while still hot with a microwave safe plate or cover will help the oatmeal soak up excess moisture and become fluffy.
  • All microwave oatmeal recipe details are in the recipe box below.

Quick Oats vs. Old Fashioned Oats?

Our microwave oatmeal recipe uses old fashioned oats because you’ll have better texture and bite. Quick oats will be mushy because of the way they’re processed. Quick oats are rolled thinner and pre-cooked for longer, which makes them quicker to cook but mushy. That’s why our recipe is for old fashioned oats because you have a much better texture. But if you want to use quick oats, just expect that the results will be mushier oatmeal.

Microwave Easy Oatmeal with Old-Fashioned Oats

This is for Old Fashioned Whole Grain Rolled Oats (different brands will use some variation of that – Rolled Oats, Old Fashioned Oats, Whole Oats, etc.) Do not use Instant or Quick Oats. They will cook mushy using this technique.
All microwaves cook differently even if they are of the same size and wattage. You might need to adjust your cooking time. After you cooked your first batch, you’ll know what time is best for your specific microwave and personal taste.

Refer to Your Microwave Manual for Safety & Cooking Guidelines
General microwave cooking time notes:
  • 600-800w – Lower Wattage Microwaves: More time often needed
  • 900-1100w – Average Wattage Microwaves
  • 1200-1300w – High Wattage Microwaves: Less time often needed
Microwave Safe Containers & Lids
  • Microwave safe glass (particularly borosilicate glass) & ceramic containers are the recommended choice. *Do not use cracked or otherwise damaged containers.
  • Microwave safe plastic containers are considered safe by the FDA but many health organizations caution against using them
  • Never use plastics (containers, bags, wrap, etc.) that are not labeled microwave safe. Never use styrofoam, metal, or aluminum foil. 
  • Lids – microwave safe glass, ceramic or silicone is best. A microwave safe plate works great as a lid. Parchment paper, wax paper, or paper towels work fine, but may not hold the steam in as much (many recipes benefits from the steam retention). Microwave safe plastic lids are considered acceptable. Usually we prefer to use a lid from glass, ceramic, or silicone and just use the microwave safe plastic lids that come with the containers for storing.
