Can you imagine eating a bowl of bananas foster overnight steel-cut oats for breakfast and calling it “healthy”?
I live right outside of New Orleans where the classic Bananas Foster dessert is a thing. However, I’d never eat it for breakfast because all that butter, sugar, and ice-cream… well, it’s no breakfast material unless you spent too much time on Bourbon Street.
If you’re looking for a version of this recipe with old-fashioned oats (the flakes) check out this post.
Whether it’s the large bag of un-used steel-cut oats sitting in your pantry or the drool-worthy idea of bananas foster for breakfast that brought you to this post, I’m glad you’re here!
Besides using steel-cut oats can be used to make oat flour or to make my Strawberry Overnight Steel-Cut Oats recipe, it’s time we take it up a notch with this epic recipe💥

Overnight Steel-Cut Oats
Let’s talk about the pink elephant in the room: what are overnight steel-cut oats?
Let me give you a brief summary: overnight oats are dry oats that are mixed with a liquid (milk preferably), some type of sweetener (the bananas foster part of this recipe) and any other add-ins you want (I’m not suggesting you top your oats with ice-cream, btw😉)
When it comes to making overnight steel-cut oats, you can either mix everything in a large bowl or inside individual jars, place the oat mixture in the refrigerator overnight, and wake up to an epic breakfast option. Sounds simple, right? Jussst wait.

What are Steel Cut Oats
Steel-cut oats also called coarse oatmeal or Irish oatmeal is groats of whole oats chopped into two or three pinhead-sized pieces (sort of like long-grain rice).
Benefits of Steel Cut Oats
Steel-cut oats are an excellent source of protein, soluble and insoluble fiber and minerals. They make a terrific base for breakfast or grain-based meals. And, they can be ground into a flour 🤯

Steel Cut Oats vs. Rolled Oats or Old Fashioned Oats
Steel-cut oats are minimally processed, so they contain more fiber than rolled oats. Steel-cut oats are round, shaped like long-grain rice but larger, and they contain the whole grain.
In comparison, old fashioned oats are flat, large flakes of oat kernels that have been processed through a machine to “flatten” them and give them their flake-like shape and texture.
By flattening the groat (the whole oat) cooking time is reduced, and therefore, rolled oats take less time to cook than steel-cut oats. Nutritionally, they are the same with slightly reduced fiber and protein content.
Steel Cut Oats to Water Ratio (or milk)
For every 1 cup of steel-cut oats, you’ll need 2 ½ to 3 cups of liquid, depending on how thick you’d like them to be. Less liquid will yield a thicker bowl of oatmeal or overnight oats.
You can use either milk or water to make overnight oats. I personally love using milk or unsweetened almond milk, like you’ll see in the recipe below because it provides the oats a creamy texture that’s 100% delicious.

Steel-Cut Oats Nutrition
The least “processing” to any grain or ingredient, the more nutritionally dense that ingredient will be. By themselves, 1 serving, about ⅓ cup or 45g of dry Steel-cut oats has 170 calories, 3 grams of fat, 29g carbohydrates, 5g fiber, 7g protein. For this recipe, I’m using fewer oats, ¼ cup, since we’re adding volume from the bananas.
How to Cook Steel-Cut Oats Overnight
One of the advantages of making these overnight oats in the fridge is that it’s a no-cook method. Meaning, the oats are going to soak up the liquid while they are stored in the refrigerator in a jar overnight, and in the morning, they will be ready to eat.
This means that you don’t need to learn how to cook steel-cut oats when you make overnight oats because they practically “cook” themselves as they soak in the liquid.

Steel-Cut Oats Recipe with Bananas
This recipe for bananas foster overnight steel-cut oats is one of my favorite recipes when I want sweet oatmeal for breakfast.
I mean, oats + milk isn’t really that exciting and by adding bananas + cinnamon + maple syrup… Woah. We totally just made an epic breakfast/dessert that’s nutritious and delicious.
The coarse texture of steel-cut oats is perfect when combined with sweet ripe bananas + cinnamon is incredible. Plus, as a bonus, you can even use frozen bananas that you’ve meant to use on smoothies.
For this recipe, you’ll need:
- Steel-cut oats: to give overnight oats a great texture and consistency.
- Milk: any type of milk or your favorite dairy-free milk alternative.
- Bananas: not too green nor too ripe bananas are the best. That said, use any banana you have on hand!
- Butter: to sauté the bananas. Swap it for coconut oil to make this recipe dairy-free.
- Vanilla: adds an irresistible flavor to the oats.
- Cinnamon: a little goes a long way!
- Maple syrup: mixed with the natural sweetness of banana, makes these overnight oats the ultimate dessert-like breakfast!
How Far in Advance can I make Steel-Cut Overnight Oats?
One of the claims to fame of overnight oats is that they can be made ahead and kept in the fridge for several days. If you’re making overnight oats without fruit, you can make them up to 5 days in advance.
If you are adding fruit to your overnight oats, I recommend no more than 3 days since the fruit loses its texture and taste different -especially berries.

What are the best Jars to use for Overnight Oats?
Most recipes call for 8-ounce mason jars. These are available in glass or plastic. If you have young kids, these freezer jars are great for making overnight oats and freezing smoothies.
You can also make overnight oats in a large bowl, cover it with plastic wrap or a lid, and then measure out the overnight oats mixture into individual bowls.
The biggest takeaway for the best “jar” is that the container has a lid to prevent any spills in the refrigerator and that they are covered airtight.
How Long do Overnight Oats Take?
Since overnight oats don’t require cooking, they take time to soak in the liquid added to the jar or bowl. They are called “overnight” because they require 8 hours at a minimum to soak in the liquid. Steel-cut oats will take closer to 12 hours to soften up.
Should Overnight Oats be Warm or Cold
I personally love eating overnight oats cold, straight from the refrigerator. Some people, like them warm or even hot. This comes down to which you prefer – try it both ways and see how everyone in your family likes their oats.
Microwaving Overnight Oats
If you want to heat your overnight oats up quickly, you can put htem in the microwave for about a minute, then mix to combine and be sure they are heated all the way through.
What Else to Put in Steel-Cut Overnight Oats
What’s great about making oatmeal with overnight oats is that it’s a “base” for terrific add-ins. In this recipe, I use bananas but below are other ways you can customize your one-bowl meal.
Some of my favorite mix-ins:
- ground flaxseed, ½ teaspoon per serving
- honey or maple syrup, 1 teaspoon per serving
- hemp seeds, 1 teaspoon per serving
- chia seeds, ½ teaspoon per serving
- nut butter, 1 teaspoon per serving
- protein powder, 2 tablespoons per serving
- fresh fruit, ½ cup per serving
- dried fruit, 1 tablespoon per serving
- chopped nuts, 1 tablespoon per serving
Whether you add the add-ins before you refrigerate or after, the possibilities are endless!

Hi! I have been enjoying ALL your overnight oat recipes, and looking forward to some of your other oatmeal recipes for the Fall and Winter.
I had a quick question about this recipe though. In your video instruction you say about 1 1/2 bananas but in the written instruction you say 3 bananas. Can you confirm how many you use for the 4 serving size? Thank you so much!
Laura Fuentes
You are correct! Thank you for catching the discrepancy. 1-2 bananas are it! If they are small, 2 will fit. Somtimes, when I use one of those huge Sam’s club bananas 1 is enough! lol
Jenna
I made these banana steel cut oats for this week and I’ve enjoyed them both warm and cold. Terrific recipe!

I love overnight oats, but this Bananas Foster might be my favorite!
