Peanut Butter Overnight Oats

Peanut Butter Overnight Oats

These peanut butter overnight oats are my family’s go-to breakfast as it’s packed with protein and healthy fats to keep you full for hours. Plus, it’s so creamy that it almost feels like eating peanut butter cookie dough for breakfast.

When I was a clinical dietitian, I spent my days talking to a lot of people about their eating patterns and what types of foods they like to eat. And it always shocked me how many people either can’t tolerate eating in the morning or just get too busy and forget to eat. That last one really baffles me – I don’t think I’ve ever “forgotten” to eat, priorities I guess ;). Plus, if I were to skip breakfast, I’m pretty sure I’d have a full-on melt down in the office and be unable to focus on anything.

All of this boils down to a simple fact: I love to eat. And I especially love eating breakfast. In fact, the first thing I usually think about in the morning is grabbing something to eat.  But I can’t just grab anything, as my appetite is crazy when I first get up – I’ve even considered challenging Bry to a pancake-eating contest to take advantage of the fact that my bear-sized appetite could so beat his normal-person level of hunger at breakfast time.

Oats, chia seeds, and natural peanut butter in a glass

While there are many other overnight oat recipes that I like and do make on occasion, these peanut butter overnight oats are our go-to breakfast as they are so creamy and filling (plus the day just doesn’t feel right without a healthy dose of peanut butter 😉 ). All you have to do is stir together the 6 ingredients in a mason jar, empty peanut butter jar, or Tupperware container, place it in the fridge overnight, and grab it on your way out the door. You could even make a big batch on Sunday and be set for the rest of the week. So now there’s no excuse for being “too busy” for breakfast.

Note that these oats are very thick! So if you like thinner oats, I recommend increasing the amount of milk or decreasing the yogurt. It can take a little trial and error to figure out exactly how you like your overnight oats, but once you find that sweet spot I promise you’ll be hooked!  

Nutrition shout-out: In addition to making your morning easier, these oats are also a healthy choice with 9 grams of heart-healthy fiber and 17-19 grams of protein to keep you full until lunch time (protein content will vary depending on what type of milk you use).

So here’s a toast to eating healthier without sacrificing time (or flavor)!
