Banana Nut Overnight Oats are a great breakfast to have ready when your mornings are busy and you barely have time to make coffee.
You can make them the night before, leave them in the refrigerator, and wake up to a delicious breakfast that’s already waiting for you.
If you love banana bread, you’ll enjoy the sweet banana and cinnamon flavors in these creamy overnight oats. The chopped walnuts give every serving a nice little crunch, and the Greek yogurt makes them extra creamy.
There’s no cooking involved, which makes this an easy breakfast to add to your weekly meal prep.
All you need is a mixing bowl and a couple of mason jars or airtight containers. You can even prepare both servings at once, so breakfast is taken care of for two mornings or for two people.
Each serving has 17 grams of protein and 8 grams of fiber, making these oats a filling way to start your day. They’re also easy to customize with different nuts, milk, or toppings.

Why You’ll Love This Banana Nut Overnight Oats Recipe
Breakfast Is Ready When You Are
No need to spend your morning cooking. These oats soften in the refrigerator, so you can grab a jar and enjoy breakfast whenever you’re ready.
A Great Way to Use Ripe Bananas
Have a banana on the counter that’s getting a little too soft? It’s perfect for this recipe! Ripe bananas mash easily and give the oats plenty of natural sweetness.
A Filling Breakfast With Protein and Fiber
Each serving has 17 grams of protein and 8 grams of fiber. That’s a nice combination when you need breakfast to keep you satisfied throughout the morning.
Just Enough Crunch
The walnuts add a little crunch to the creamy oats. Save some for the topping so you can enjoy that texture when it’s time to eat.
Easy to Make Ahead
This recipe makes two servings, so you can prepare breakfast ahead without filling your refrigerator with containers. It’s especially handy when you’re planning meals for the next couple of days.

Ingredient Substitutions
Old Fashioned Rolled Oats
Quick oats can be used instead, but they’ll have a softer texture. Avoid steel-cut oats as a direct substitute because they need a different amount of liquid and a longer soaking time.
Milk
Unsweetened almond milk, oat milk, or soy milk can replace regular milk. Use the same amount.
Plain Greek Yogurt
Vanilla Greek yogurt works great if you prefer a sweeter breakfast. You can also use a dairy-free yogurt, although the protein content may change.
Pure Maple Syrup
Honey can replace maple syrup in the same amount. You can also reduce the sweetener if your banana is especially ripe.
Chopped Walnuts
Chopped pecans are a great alternative and have a similar crunch. Sliced almonds also work, although they’ll give the oats a different texture.
Ground Cinnamon
Pumpkin pie spice can replace cinnamon for a slightly different flavor. Use the same amount.

Notes
Tips and Tricks
Choose Ripe Bananas – Bananas with brown spots are sweeter and easier to mash, making them perfect for overnight oats. Adjust the Thickness – If your oats are thicker than you like, stir in a splash of milk before eating. Keep the Walnuts Crunchy – Store the walnuts reserved for topping separately until serving time if you prefer a firmer crunch. Add Banana Just Before Serving – Fresh banana slices taste better and won’t turn brown while the oats are refrigerated. Use Containers With Lids – Mason jars or airtight containers make these oats easy to store and take with you.Storing
Refrigerator – Store the overnight oats covered in the refrigerator for up to 3 days. Keep the fresh banana topping separate until ready to serve. Freezing – Freeze the prepared oat mixture without the fresh banana slices or reserved walnuts in freezer-safe containers for up to 2 months. Thaw overnight in the refrigerator before serving. The texture may be slightly softer after thawing.Nutrition
