Quick Breakfast for Busy Mornings
Back in the day, when I worked in New York City, I’d prep overnight oats with banana and peanut butter the night before. Oats are the easiest breakfast to make, and I wasn’t about to spend $10 bucks on breakfast in NYC (nowadays, probably more).
Once I got to work, I would check my emails and enjoy my overnight oats in a cute mason jar. They’re satisfying and so filling.
As I’ve gotten older, I’ve realized the need for more protein in my diet, and I prefer to get it from food when possible. This recipe is inspired by the original peanut butter banana overnight oats recipe with the addition of Greek yogurt for a protein boost.

Why You’ll Love This Recipe
- High Protein – These overnight oats are delicious and will keep you full and satisfied throughout the day. No protein powder is used; instead, these oats are made with all-natural ingredients from Greek yogurt.
- Nutrient-rich – Oats are good for you and a great source of fiber. This recipe also includes chia seeds, which are rich in fiber, protein, healthy fats, omega-3 fatty acids, and antioxidants.
- Easy Meal Prep – Meal prep oats days in advance. These oats take only 5 minutes to prep as no cooking is required. Simply grab and go.
Ingredients

- Greek Yogurt – To make high-protein overnight oats, use Greek yogurt. Here, I’m using a container of 2% reduced-fat Fage Greek yogurt, which contains 15 grams of protein.
- Old-Fashioned Oats – My favorite new brand of oats is One Degree Organic Foods, which are 100% transparent and glyphosate-free. You can choose whichever oat brand you prefer; I like using cleaner products where possible.
- Almond Milk – Use unsweetened almond milk, as the banana already contains enough sugar. Many almond milk brands contain gums, so I opt for brands without them, such as Malk Unsweetened Almond Milk, Three Trees Unsweetened Almond Milk, or Califia Farms Organic Unsweetened Almond Milk (3 ingredients).

Substitutions
- Vegan – Use vegan Greek Yogurt and non-dairy milk.

Serving Suggestions
→ My favorite way to enjoy these oats is with a few berries and sliced almonds on top.
→ You may top with seasonal fruits. Chopped peaches, apples, pears, figs, and raspberries would all be great additions. You may also top with walnuts, pecans, pumpkin, or sunflower seeds.
Storage
How long can I store overnight oats in the fridge?
Since this recipe contains yogurt, I would recommend leaving it in the fridge no longer than 3 days for the best results. Furthermore, store the overnight oats in an airtight container for multiple days.

Looks delicious; I was wondering why the banana is left off of the list of ingredients, although it is then mentioned in the instructions…
Thanks Nancy. Sorry about the typo, I missed adding the banana to the ingredient list. Thanks for pointing that out – it’s been fixed now. 🙂
I made these today for breakfast and they were SO DELICIOUS and easy to make. Yum! I’m so full and love the protein amount. Thanks for a great share.
