Cold winter weather begs for a warm and hearty breakfast. In our house, that usually means we rotate between freezer pancakes and oatmeal.

While I’ve shared countless oatmeal recipes with you over the years, it dawned on me that I’ve never shared the one recipe I make most: The ULTIMATE 90 Second Microwave Oatmeal!

90 Second Oatmeal Recipe

Not only is oatmeal extremely nutritious and versatile, but it is also gluten-free. For those of you with a gluten allergy, I highly recommend Bob’s Red Mill Gluten Free Oats made in their 100% gluten-free facility and tested for gluten again to ensure their purity. In fact, I got to tour the factory and see this process up close and personal during my visit to Portland last year!

Pouring Milk

Frequently Asked Questions:

What are the best oatmeal toppings to choose from?

The best topping for oatmeal is peanut butter for protein, berries, oats, banana slices, chia seeds, almonds, or raisins.

What is the ratio of oats to milk for oatmeal?

I typically do a 1:1 ratio. One cup of oats to one cup of milk but if you want the oats to be looser I would suggest adding a little more milk.

Can quick-cooking oats be used in the microwave?

Quick-cooking oats in the microwave will make things super mushy to the point you won’t feel like eating breakfast. If you want perfect oatmeal you need to use old fashioned oats.

How do you make hot oatmeal kid-friendly?

Many times oatmeal coming out of the microwave is too hot for kids. If you want to cool it down quickly, mix in some frozen berries when it comes out of the microwave. That will bring the oatmeal down to the right temperature for the kiddos.

What types of milk can be substituted in oatmeal?

If you’d like you can substitute rice milk or water for whole milk. You would substitute with the same quantity of whole milk in the recipe.

Your spoon is waiting.

    I thought this was delicious. I like my oatmeal chewy but wet, so I just poured skim milk in the bowl before I ate it, which is what I always do, stovetop or microwave. The vanilla was a brilliant idea! And 1/4 tsp of cinnamon was perfect. One question though. Can I use skim milk for the cooking part, instead of whole milk? I don’t want the extra calories. With milk to thin it, chopped walnuts, sliced banana, and a small squeeze of honey, it was my perfect breakfast, without dirtying that horrid oatmeal pot! Thank you so much. This will be on my regular rotation.

    This makes mornings so much easier! I have one early riser who wants to eat as soon as she wakes up and a son who likes to sleep in—now everyone can make their oatmeal when they’re ready for it. Thank you for the great idea. (And we loved the addition of the vanilla! We’ve never tried that before, and it was great!)

    I prefer the “bland, mushy” quick cooked microwaved oatmeal.

    I didn’t read all the comments, but I think this is a brilliant idea! I needed to cook mine in my microwave for almost double the time and added a bit more milk. And I prefer chewy oatmeal. But this saves me from having to wash that oatmeal pot, which almost ruins the joy of eating oatmeal! So thank you for such a great idea.

    Does the oatmeal turn out loose or thick?

    Hi. If I want to substitute rice milk or water for the whole milk, would I use the same amount? Thank you!

      Yes absolutely!

    The ingredients that is shown has “1/2 cup of whole milk” vs 1 cup whole milk which I believe is the correct amount. The ratio of liquid to oatmeal is “2 to 1” whether it be milk, water or other choices like coconut or almond milk.

      Hi Eldridge, I actually prefer a 1:1 ratio so we do 1/2 cup oats to 1/2 cup milk but if you want your oats to be a bit more loose you’re welcome to add more! :)

    I just made mine and for a lazy person this was the most spectacular experience I’ve ever encoutnered. I have celiacs disease and finding alternatives is expensive and restaurants don’t usually provide options for people like me. Loved this to its absolute pleasure. Thank you.
