These High-Protein Apple & Peanut Butter Overnight Oats make a protein-packed breakfast that’s perfect for meal prep. Creamy peanut butter and Greek-style yogurt deliver protein to help keep you full and energized throughout the morning. Honeycrisp apples have the right balance of sweet and tart flavors, and hold up well after chilling overnight. As the fiber-rich oats soak, they absorb all the creamy, nutty and subtly sweet flavors, resulting in a grab-and-go breakfast that’s both filling and delicious. Want to give them a try?

Tips from the EatingWell Test Kitchen

These are the key tips we learned while developing and testing this recipe in our Test Kitchen to make sure it works, tastes great and is good for you too! 

Try swapping out the cinnamon for apple pie spice for a cozier flavor. 

We prefer to use natural peanut butter, which doesn’t typically have additives like sugar or hydrogenated oil, which is often used to prevent nut butter from separating. If your jar of natural peanut butter has separated, give it a good stir before making this recipe. 

Be sure to refrigerate the overnight oats for at least 8 hours before serving, allowing them to thicken properly.

Feel free to use any apple you prefer. Gala, Fuji or Granny Smith can all bring different flavors and textures to the dish.

Nutrition Notes

Oats are a whole grain known for their fiber content. Fiber helps slow digestion, so you’ll feel full for longer after eating these oats. Oats are also a prebiotic food, which work to support the good bacteria in your gut. 

Soy milk is a good source of plant-based protein. Look for unsweetened soy milk to avoid excess added sugars. Fortified soy milk will have additional calcium, a nutrient crucial for bone health.

 

Strained (Greek-style) yogurt is packed with protein, an important nutrient that plays a role in many bodily functions, from building muscle to digestion. Along with protein, Greek yogurt is also low in sugar and carbohydrates—which is a beneficial combination for stabilizing blood sugar. 

Apples contain phytochemicals that may help reduce the risk of certain cancers, including lung, breast and pancreatic. The fruit may also promote heart health by lowering total cholesterol.
