About This Recipe

These Overnight Oats with Mango and Walnuts are a fresh, easy way to start your day. They’re made with creamy oats, naturally sweet mango, and crunchy walnuts for an easy breakfast that is packed with fiber, healthy fats, and satisfying flavor.

Overnight oats are the best because everything comes together in just a few minutes the night before to make your busy mornings effortless.

I love this combination because the juicy mango adds natural sweetness while the walnuts bring a delicious crunch, creating the perfect balance of texture and flavor.

Whether you’re meal prepping for the week or need a quick grab-and-go option, these overnight oats are a simple, macro-friendly breakfast you’ll actually look forward to.

Ingredients and Substitutions

Old-fashioned oats: Use gluten-free if needed.
Almond extract: You can also just use vanilla.
Milk: I used unsweetened SILK cashew milk, but any milk of your choice works.
Protein powder: Grab your favorite protein powder. I recommend using vanilla. My favorite brands are Clean Simple Eats, or for a dairy-free option, I love Active Stacks! Use LILLIE for a discount.
Chia seeds: Any type of chia seeds (black, white, or a mix) works for this recipe. Chia seeds are a great source of omega-3s and protein. They will absorb the liquid overnight and expand in size, so don’t worry if it doesn’t look like a lot when initially mixed.
Sweetener: I prefer to use a liquid sweetener like liquid stevia or monk fruit for these overnight oats. I personally just like how the liquid blends in, but any type of sweetener will work! You can also use honey, maple syrup, agave, etc.
Non-fat Greek yogurt: Helps to make these oats extra creamy!
Mango: Fresh diced mango or frozen chunks of mango work too! You can let them thaw first, or just enjoy frozen. We love both!
Walnuts: Adds the perfect crunch (feel free to sub for any other nut you love or omit).

Dietary Adaptations

GF/DF: Make sure to use gluten-free oats, a dairy-free protein powder (Active Stacks is my favorite), and your favorite dairy-free yogurt.

How To Make

Combine oats, chia seeds, vanilla extract, cashew milk, stevia, and protein powder in a jar or other lidded container and refrigerate for at least four hours or overnight.
Remove from the fridge and add yogurt (I like to sweeten with a little more liquid stevia or monk fruit first), whipped cream, diced mango, and walnuts. Enjoy!
