As a dietitian and mom of two energetic kiddos, breakfast is a non-negotiable in our house. And it’s gotta be something that won’t have them asking me for snacks 2 seconds later. Overnight oats are perfect for this, especially these ones.

First of all, I cannot get over the flavor combo! But also, if you’ve never tried overnight oats with chia and yogurt, this is your sign! These might seem like casual add-ins, but trust me they are game-changing for creating a super creamy texture that’s also going to keep you full a lot longer. And possibly the best part? These oats are meal prep heaven! The whole batch comes together in just 15 minutes, then just pop them in the fridge to set overnight. When you’re ready to eat, just grab a jar, dig in, and enjoy every creamy, crunchy, lemon-blueberry-filled bite. You’re gonna to love them!

(PS–if you’re an overnight oats fan like me, you’ve also gotta try my PB and J oats and blended chocolate peanut butter oats, which both have chia seeds by the way!).

Ingredient Highlights

Quick Oats: Through all my years of testing overnight oats recipes, I’ve developed the opinion that quick oats work best. With a softer texture, they create a creamier base which I prefer over the chewier texture of rolled oats. As a bonus, they also soak up the liquid faster so they don’t require the full “overnight” period to set (I may have eaten these 45 mins after making them). 

That said, If you don’t have quick oats on hand, rolled oats will totally work! Either way you’re still getting the same blood sugar balancing, and filling benefits of their high soluble fiber content.

Chia Seeds: I’ve tested overnight oats both with and without chia seeds and for me they’re a must. Besides being little nutrition powerhouses—adding further to the fiber count (8 grams per serving), as well as anti-inflammatory omega-3s, and a good dose of calcium—chia seeds help the oats set, while making them extra creamy and an almost pudding-like consistency! 

Greek Yogurt & Hemp Hearts: Often overnight oats are missing protein which plays an important role in keeping us full longer. I love this power combo, giving this recipe an impressive 25g protein per serving! And of course, we don’t mind the extra boost of calcium, gut supportive probiotics and Omega-3s either 😉

Walnuts: Not a typical overnight oats ingredient but I just couldn’t resist the texture contrast of the crunchy walnuts with the otherwise smooth mixture. Walnuts are also well known for their antiinflammatory potential so support brain and heart health! 

Let’s Make Them

A glass bowl filled with fresh blueberries coated lightly with lemon zest and sugar.

You want to make the blueberry layer first to give it a chance to thaw a bit, making it all juicy, allowing the flavors to blend better.

To make the oat mixture, just toss everything into a bowl and whisk until combined. It really doesn’t matter what order you add the ingredients.

Next, we layer. If you want to simplify, just divide the oat mixture, then top with the blueberry filling, rather than layering. Add more Greek yogurt on top if you like for a boost of extra protein and nice little topping!

Set in the fridge overnight (or at least 45 mins-an hour ish)

Description

Ok wow! These lemon blueberry overnight oats are bursting with fresh flavor and are truly the ultimate make-ahead breakfast! Greek yogurt and hemp hearts pack in the protein (no protein powder required) and chia seeds make for an irresistibly creamy texture. Prepped in just 15 minutes, you’ve got balanced, filling breakfasts ready for the entire week!

Ingredients

Scale
  • 2 cups frozen blueberries
  • Juice and zest of ½ lemon
  • 2 cups quick oats
  • ¼ cup chia seeds
  • ½ cup hemp hearts
  • 2 ½ cups milk of choice
  • 2 cups plain or vanilla Greek yogurt
  • 2 Tbsp maple syrup
  • 1 teaspoon vanilla
  • ½ tsp salt
  • ½ cup walnuts, roughly chopped

Instructions

  1. To a microwave safe bowl, add blueberries, lemon juice, and lemon zest and mix to combine. Microwave in 20 second increments until thawed but still cold, set aside. 
  2. To a large bowl, add the oats, chia seeds, hemp hearts, milk, 1 ½ cups of the yogurt, maple syrup, vanilla and salt. Whisk until well combined. 
  3. Divide half of the oat mixture between 5 sealable jars or airtight containers, then layer ¾ of the blueberry mixture between them, followed by the remaining oat mixture. Finish by dividing the remaining yogurt and blueberry mixture on top. 
  4. Place in the fridge to set overnight. These will keep for up to 5 days.

Notes

Layering vs. mixing all ingredients together: To simplify the process, skip the layering and add all of the Greek yogurt right into the oat mixture, divide the oat mixture between the jars, then top with the blueberry mixture. 

Storage: If you don’t need individual servings, you can just mix the oats in one big sealable storage container to set and scoop out portions as needed. Store the blueberry mixture separately and top each serving when you’re ready to eat!

Yogurt: I usually make these with plain Greek yogurt but if you’re looking for something a bit sweeter, opt for vanilla!

Milk: I usually use 2% milk but any milk will work! For the highest protein option, opt for dairy, or soy milk for a plant-based version!
