Easy Microwave Oatmeal will make you fall in love with oatmeal and is so much better than the packets available in the store. Plus it's healthier, more affordable, and can be customized any way you like.

Oatmeal lovers will also want to try these Oatmeal Protein Pancakes and Oatmeal Smoothies.

The key to making delicious microwave oatmeal in less than 3 minutes comes down to three things - using milk instead of water, choosing old-fashioned rolled oats (not instant!), and adding a touch of cinnamon and vanilla.

From there you can dress it up any way you want and you are guaranteed to have perfect oatmeal every time.

For a long time, I ate packets of microwave oatmeal every morning believing I was having a healthy breakfast even though I wasn't crazy about the mushy texture and flavorings. I just assumed I was someone who didn't really like oatmeal.

That all changed when I finally started making my own oatmeal at home using old-fashioned rolled oats and adding my own toppings.

Not only was the oatmeal 100 times tastier, but the texture also was so much more appealing. Plus it is more affordable. I could buy a whole container of rolled oats for about the same amount as the 6-8 packets.

If saving money, eating healthy, and enjoying delicious meals are things that interest you, you’ve got to try The Best Microwave Oatmeal. You won’t be disappointed!

Key Ingredients

You will need the following key ingredients to make this delicious breakfast recipe:

  • Rolled Oats: You can use quick oats or rolled oats, but keep in mind the cooking time will differ depending on which one you choose.
  • Milk: I prefer to use unsweetened almond milk in my oatmeal recipes, but you can use any type of milk you like including dairy milk, soy milk, or oat milk. If needed, you could also use water.
  • Cinnamon: This warm and delicious spice is commonly used in oatmeal recipes because of how beautifully it complements the nutty flavor of the oats. Add a pinch of salt as well to make the flavors pop.
  • Vanilla extract: Not only does vanilla extract add a bit of its own flavor, but it also enhances the other flavors in the dish and ties everything together.
  • Optional extras: This is where things get fun! If you like things sweet, stir in some maple syrup, honey, or brown sugar. Add fresh or dried fruit like berries, bananas, raisins, cranberries, or apples. Add healthy fat and crunch with some chopped nuts like walnuts, pecans, or almonds. Get inspired by dessert with chocolate chips and melted peanut butter. 

Flavor Ideas for Microwave Oatmeal

There are so many ways to customize this easy microwave oatmeal. Try one of our flavored microwave oatmeals - Banana Peanut Oatmeal, Apple Oatmeal with Peanut Butter, Pumpkin Pie Oatmeal, or Blueberry Muffin Oatmeal or use one of the ideas below. 

  • Banana Peanut Butter: The oatmeal I eat most often is a simple combination of bananas and peanut butter. Just mash up a banana in the bowl before adding the oats and then follow the directions as usual. Not only will this sweeten up the oatmeal naturally, but it also makes the oatmeal super creamy and delicious. Add a dollop of peanut butter for one filling, tasty breakfast.
  • Cinnamon Apple: We almost always have apples in the house, so I love making cinnamon apple microwave oats. Start by dicing up an apple. Place it in your bowl and microwave for 60-90 second until it's soft. Then add the oats, milk, cinnamon, and vanilla and you'll end up with oatmeal packed with apple flavor without the need for added sugar or sweetener.
  • Peanut Butter & Jelly: We love peanut butter and jelly so when I am in a rush I top my oats with some no sugar added preserves and a scoop of nut butter. Sometimes I use halved grapes or strawberries instead of preserves to keep the oatmeal nice and light,
  • Fruit and Cream: I love adding fresh fruit to my oats and usually add a scoop of Greek yogurt as well to create creamy oatmeal packed with fruit. This also ups the protein content of the oatmeal to keep you full all morning.
  • Pumping up the nutrition: To pack even more nutritional benefits into your morning oats, I almost add a teaspoon of chia seeds and flax meal to my oats. Sometimes I add protein powder as well, especially when I know I have a long morning and need lots of energy

How long to cook oatmeal in the microwave?

Here are the general guidelines for cooking oatmeal using the microwave. Cooking time will vary based on the type of oatmeal and the strength of your microwave.

  • Quick-cooking oats: Cook on high for 1.5-2 minutes.
  • Rolled or old-fashioned oats: Cook on high for 2.5-3 minutes.
  • Steel-cut oatmeal: Generally, it isn't recommended to cook steel-cut oats in the microwave since they take significantly lower to cook.  Here is how to cook them on the stovetop.
  • Instant oatmeal and oatmeal packets: Instant oatmeal is similar to quick cooking and usually takes around 1.5-2 minutes to cook.

How to Store Microwave Oatmeal

Let’s say you pop some oatmeal in the microwave for your youngster, only to find out that they are in a mood and will absolutely not eat anything but cereal.

What do you do with that poor, delicious oatmeal? You save it, of course!

Oatmeal holds up really well both in the fridge and in the freezer. Simply let it cool to room temperature, then transfer it to an airtight storage bag or container.

Once properly contained, you can store cooked oatmeal in one of two ways:

  • In the fridge for up to 4-5 days.
  • In the freezer for up to 3 months.

Frequently Asked Questions

Below are the answers to some of the most frequently asked questions about this dish:

The easiest way to make sure your oatmeal doesn’t boil over is to use a larger container than you think you need. When you use a small container, the milk or water tends to bubble over and spill out of the container during the cooking process. Another good option is to cook the oatmeal in 30-second increments, giving it a quick stir every 30 seconds.

Yes! Instant oats and rolled oats are the same grain, so they are equally as healthy. The only difference between the two is how they are processed. Rolled oats are flattened out for quick cooking, while instant oats are pre-cooked and dried for even quicker cooking.

Even though this is a 3-minute recipe, sometimes I like to make a double or triple batch and store the leftovers in the fridge for an even easier breakfast. These oats will keep well in the fridge for 3-4 days. To reheat, add a touch of milk and stir. Then reheat for 30-60 seconds until heated through. For freezer oatmeal meal prep, try these Frozen Oatmeal Cups.

This is entirely based on your own preference! Everyone is different. Personally, I love making my oatmeal with milk because I find that milk makes it creamier. However, water will work perfectly fine too.

The best oatmeal toppings are whatever you want them to be. Truly! Some of my favorite choices include fresh fruit, dried fruit, chopped nuts, seeds, nut butter, and Greek yogurt. The options are basically endless, so you can switch it up every time you make oatmeal in the morning.

I am looking forward to trying this recipe! night, lol. I found out oats have naturally occurring melatonin so I quit eating oats in the morning. I also noticed I'd have a brutal midmorning crash whenever I'd eat oats/oatmeal. I switched to a more savory meat, cheese, eggs type breakfast and no more crashes! Apparently, some people, including me, have a sensitivity to grass foods. Oats, wheat, and barley are grasses. If this is you, try switching to a breakfast with no grains that includes a protein and vegetables (kimchi is great for breakfast). Thanks for letting me share my two cents, happy sleeping!

Just what I needed! Thank you! I ate steel cut oats daily prepared in large batches in a slow cooker with milk, for years and got so tired of them. Rolled oats have a different flavor and texture. I'm so happy to have rediscoverd them!

Using a Sharp 1200 watt Carousel microwave I have had the best results using the beverage setting for just over the oatmeal recipe volume. For this recipe the 1.5 cup beverage setting cooks and does not boil over. For a 3/4 half recipe try the 1 cup beverage setting on your microwave.

You must put this in a very large bowl, or yes, it will overflow. This came out kind of runny at first but then when it cooled it became the perfect consistency. I love to double the cinnamon, add frozen berries for taste and to cool, and a tablespoon of ground flaxseeds. Yum!

My new favorite way to make oatmeal in the microwave. So much better (and cheaper) than the packets. Usually I add some fruit and I top everything with yogurt.

I tried this and the oatmeal overfilled the bowl and made a large mess in my microwave. Make sure to microwave in about 30 second bursts, not for 3 minutes at a stretch. At least not in a high-powered microwave.

Sorry to hear this! It's important to use a large bowl so that the oats don't overflow during cooking. I am going to add a note about this to the instructions. Thanks for the feedback.
