Steel Cut Oats
My hubby eats steel-cut oatmeal or overnight oatmeal every single morning (he’s obsessed!), which is why I make a big batch of this easy breakfast and divide it into individual servings for 3-4 days. Use a simple meal prep container or mason jars to store the oats.
While we love the nutty flavor of steel cut oats, the health benefits are a factor too. Steel-cut oats are minimally processed and contain more fiber and density than their counterparts.
Why This Recipe Works:
- QUICK – You can have breakfast on the table in just one-half hour. The best part is that it’s mostly hands-off.
- HEARTY and FILLING – The chewier texture of steel-cut oats adds heartiness to this filling breakfast.
- A HEALTHY BREAKFAST – There is a ton of nutrition in oatmeal, and this recipe contains 21 grams of protein in each serving along with plenty of fiber and vitamins.
- DELICIOUS FLAVOR – Peanut butter and banana are truly a delicious combination. Plus we love the sweetness of the brown sugar along with the nutty flavor of the steel cut oats.
- PORTABLE – This instant pot steel cut oats recipe is easy to prep ahead and take it with you. You’ll just need a quick zap in the microwave the next morning.

What You’ll Need:
- Steel Cut Oatmeal – Make sure you don’t buy quick oats.
- Unsalted Butter – You’ll need a couple of tablespoons to sauté the oats.
- Milk + Water – Use the combo you prefer. I often use 2% but you could use your favorite type of milk, including whole milk, unsweetened almond milk, or others. Play with the amounts of liquid to get your desired consistency.
- Peanut Butter – I used creamy peanut butter but a crunchy version works too. You could also use almond butter or cashew butter.
- Banana – One over-ripe banana is added to the base of this recipe for some natural sweetness. Serve it with extra slices.
- Brown Sugar – For some sweetness. If preferred, use some pure maple syrup instead.
- Kosher Salt – Add a pinch of kosher salt.

How to make Peanut Butter Banana Steel Cut Oats:
Step 1
Sauté the oats. Heat up your instant pot under the sauté function. Add butter and when melted, add the oats. Stir for a couple of minutes to get it nice and toasty.
Step 2
Mash the banana. Use a fork to mash the over-ripe banana.


Step 3
Add ingredients. Add the water, milk, mashed banana, and salt – and stir well.
Step 4
Seal the instant pot to pressure cook. Turn the setting to high pressure and cook for four minutes, making sure the vent is closed. The instant pot will take about 8-10 minutes to heat up. It will beep when it’s ready. Then it will start the pressure cooking.
Step 5
Do natural release. After the four minutes of pressure cooking, let the instant pot do a natural pressure release for about ten minutes. If needed, release the remaining pressure.
Step 6
Add brown sugar and peanut butter. Then add the brown sugar and peanut butter to the instant pot and stir until well combined.


Step 7
Serve – Serve this delicious breakfast with a splash of milk and some banana slices.
Optional Steel Cut Oat Toppings:
- Chocolate Chips
- Fresh Fruit
- Granola – Try our Peanut Butter Chocolate Granola or Healthy Chocolate Granola! These both store well in the freezer!
- An extra dollop of peanut butter


Recipe FAQs:
I don’t soak my steel-cut oats before cooking with them. However, soaking them speeds up the stovetop cooking time if you are using that method.
The main difference between steel cut and quick-cook oats is texture, as steel cut oats absorb more liquid than their pre-processed counterparts while also maintaining their shape. Quick-cook oats usually bind together during the cooking process, resulting in a lightly creamier consistency.
