Meal Prep and Storage

One of my favorite things about these peanut butter oats are that they are great for meal prep. Overnight nights will stay fresh in the refrigerator for up to 1 week, which makes them the perfect meal prep breakfast!

Simply double or triple the recipe depending on how many days you’d like to enjoy them for breakfast. Then pour equal amounts of the base mixture into pyrex containers or mason jars and store in fridge.

When ready to enjoy, I like to mix in a splash of almond milk before adding the other toppings. Because the oats are in the fridge for longer, the extra splash of almond milk keeps the texture creamy and moist. Then add your favorite toppings and dig in!

FAQs

How long should overnight oats soak?

For best texture, soaking your oats 8 hours or up to overnight is best. That being said, you can do a quick soak and eat your oats within 2-4 hours if you are in a rush. With a quick soak they will not have absorbed all the liquid like they would overnight, but they will still be delicious and good to eat.

How long do overnight oats keep?

Overnight oats can last up to a week in the refrigerator when stored properly, but I think they have the best taste on days 1-3 and then less so on days 4 -5 and so forth.

Can I eat my overnight oats hot?

Yes! You can eat them warm or hot like regular oats, but you may want to try them cold first and see how you like them. If you still would like to warm them up, just pop your bowl of oats in the microwave and warm up in 30 seconds increments until warmed to desired temperature.

Should I rinse oats for overnight oats?

You can, but I don’t rinse the oats. If you find that your oats have a pasty texture, rinsing them may help with that otherwise save yourself from washing another dish by not rinsing.
