Overnight Oats with Protein Powder

Why Overnight Oats?

If you have been following me for awhile now, you know I love my oats. Hot oats can’t be beat in the winter but you will love these overnight oats with protein powder throughout the rest of the year. Hot or cold, oats are a great option for breakfast before a training session and can also be incorporated into your fueling plan in a variety of other ways. When choosing oats make sure you are opting for an old fashioned or steel cut style of oatmeal. These oats contain beta-glucans that help reduce cholesterol and keep you fueled by preventing rapid blood glucose spikes and drops throughout training. Beta-glucan is also an important prebiotic (aka food for your gut bacteria) and assists in maintaining proper GI health.

Instant oatmeal should be avoided. These oats have been stripped of many of their nutrients and often contain large amounts of unnecessary sweetener. All of the benefits have been replaced! Instant oatmeal is often one of my athletes and clients go to because of the convenience but they feel so much better when they make the easy change over to old fashioned oats.

Easy Breakfast Before Training

Overnight oats are a breakfast option that is both quick, convenient, health and cheap! Oats can also be found almost anywhere and this is an easy breakfast for travel. These overnight oats with protein powder can easily be prepared in the hotel room.

I always recommend bringing your own protein powder and preparing a batch in advance when you get to the hotel. These can be easily prepped in advance and just have to be taken out of the refrigerator before eaten. No more excuses for not eating before morning training!

This is my OG overnight oats with protein powder recipe and it can be easily modified to add in different flavors (or eliminate the protein powder). Add whatever toppings and mix-ins you like. Make it your own! Some of my favorites include: vanilla extract, fruit, nut butter, chia seeds, flax seeds, and unsweetened cocoa powder.

I would love to hear what you think of the oatmeal and how you made it your own. Comment below what you decided to top your overnight oats with!
