Creamy Instant Pot Oatmeal Recipe

This recipe is for people who love creamy oatmeal.

It’s a basic recipe for plain oatmeal so you can add whatever mix-ins you like at the end. I like making it this way so that everyone I can just put the oatmeal out with a variety of toppings and my family can add in what they like.

We add sweetener at the end also, again so everyone can make it to their own tastes (I prefer brown sugar, husband prefers honey, etc.)

What you’ll need:

  • Instant Pot Multicooker
  • Old fashioned rolled oats
  • Milk (I’ve used whole milk and 2% Lactaid milk and both worked)
  • Water

Just 4 Steps

  1. Add 1 cup oats
  2. Pour in 1 1/2 cups milk

3. Pour in 1 1/4 cups water
4. Seal lid and set Instant Pot to Porridge setting for 6 minutes

When the oatmeal is done, you can manual release immediately. I usually get caught up doing other things while my oatmeal is cooking and don’t get to it right away, and it’s always just fine.

When you open the lid, it will look very milky. Just give it a stir and I promise it will all mix together for the perfect texture of oatmeal.

Add in your favorite toppings and enjoy!

Instant Pot Oatmeal FAQs

Do I need an inner pot to make this oatmeal?

Nope! This oatmeal recipe is made right in the Instant Pot bowl.

Can I substitute the milk?

I have only ever used whole milk and 2% Lactaid milk so I can’t speak to other options. Both of those milks worked beautifully. You can try using a lower fat milk, or non dairy milks like almond milk, but if it is too thin, you may experience burning.

Why is it so bland?

I make mine this way because I am making the oatmeal for more than just myself, so we just add our own sweeteners and toppings to our individual oatmeal bowls. If you like your oatmeal sweeter, you can add your own sweetener to taste.

Can this oatmeal be stored and reheated?

You bet! I store mine in a sealed container in the fridge and reheat within a few days. You can reheat the oatmeal quickly in a microwave safe bowl in the microwave. You may need to add more milk.

When I made this, I got steam coming out the sides, and the overflow cup in the back filled up. I never had that. Anyone know why?

I've never made oatmeal without salt.

There is no "porridge" setting on my Instant Pot. Now what?
