Nessy's Note
I’ve made countless versions of overnight oats over the years (like these cinnamon overnight oats) and this banana chia version is one of my favorites.
It reminds me of banana cream pie for breakfast- sweet, creamy and satisfying- but with no cooking in the morning required. And if you’re a peanut butter lover like me, a drizzle on top takes it to the next level!
Ingredient Notes and Substitutions

- Rolled Oats- Also called old-fashioned oats or large flake oats, these create the best texture when making overnight oats (and they're also what I like best in PB and J baked oat cups).
- Substitution: Instant or quick oats work as well if you don't mind a less chewy texture.
- Banana- This naturally sweetens the oats and adds the banana flavor. For best results (like in chocolate banana overnight oats), use a ripe (yellow and slightly spotty) banana.
- Substitution: You could swap with unsweetened applesauce but you would then be making apple flavored oats.
- Greek Yogurt- Just like in my yogurt overnight oats, this is the key to making this banana chia overnight oatmeal high protein without the need for protein powder.
- Substitution: Use any plain yogurt but note that protein content will vary.
- Chia Seeds- These help to thicken the oats and add fiber, omega-3s and a bit of protein.
- Substitution: Ground flaxseeds also work or they can be left out altogether.
- Sea Salt – Enhances the flavors and balances sweetness.
- Substitution: Kosher or table salt will also work or it can be left out.
- Vanilla Extract– Adds warmth and depth of flavor that gives these oats an almost banana pudding type flavor. You can leave it out if needed.

Notes for the Best Banana Overnight Oats
- Meal prep for the week. These banana overnight oats last up to 3 days in the fridge (the banana starts to brown so I don't like to make it more than 3 days ahead), so you can prep for a few days ahead.
- Make it extra delicious. Top with extra sliced banana and a drizzle of peanut butter for even more flavor and texture.

Yes, they’re ready to eat straight from the fridge. If you prefer them warm, microwave in 20-second intervals, stirring between each, until heated to your desired temperature. Or, if you like warm oatmeal, try out this banana cream oatmeal which is made on the stovetop!
Yes but the texture will be softer and less chewy than with rolled oats.
