We have a lot of rich and decadent overnights oats recipes here on Wholefully, but sometimes you want something a little lighter and brighter for breakfast—and these Blueberry Lemon Overnight Oats fit the bill!
Plump and sweet blueberries are suspended in a creamy and tangy lemon-flavored oatmeal. This lemon-blueberry combination reminds me of warm weather and sunshine! I make these oats when I’m craving a little bit of summertime (even in the middle of winter).
What are overnight oats?
Overnight oats are a no-cook way to make oatmeal. Instead of cooking your rolled oats on the stove, you stir them together with liquid and other mix-ins, and let it all rest in the fridge overnight. It makes a great pudding-like porridge that you can eat cold, or warm up. For more on this grab-and-go breakfast favorite of mine, head on over to our Overnight Oats 101 post.
What makes overnight oats so special?
Overnight oats can be a meal prep staple in any busy household. Here’s why you’ll always find a stash in our fridge:
- Overnight oats are delicious! If you’ve never had cold oatmeal before, it may sound off-putting, but trust me! This porridge is hearty, creamy, and tastes like pudding! (But if you really don’t like the idea of eating them cold, you can heat them up, too—more on that in a sec.)
- They can be a healthy and hearty way to start the day. You get to control everything that goes into your overnight oats, so you can make them into a super nourishing, nutritious breakfast. Add some collagen or protein powder. Mix in some super seeds, like chia, flax, or hemp. Reduce the added sweeteners, or drop them completely. You can make these oats your breakfast superfood!
- Overnight oats are super easy to make in advance. Spend a few minutes mixing up your overnight oats in the evening or on the weekend, and breakfast will be ready to grab-and-go by morning. Overnight oats aren’t just easy to meal prep—they are designed for it!
- You can customize them to fit your dietary preferences. Make your overnight oats your own—they can be super nourishing or super decadent, vegan or gluten-free. We’re covering blueberry overnight oats here, but once you get a feel for overnight oats, you can discover your own favorite flavor.
- They can be made in bulk. You’ll see overnight oats on meal prep menu after meal prep menu, and for good reason—you can make a full week’s worth of breakfasts at once.
Do you eat overnight oats cold or heated up?
Most folks choose to keep overnight oats as a grab-and-go breakfast, and eat them cold (and that’s where the pudding-like texture comes in!). But if you’d rather have them hot, just warm them in the microwave for 30-60 seconds, stirring frequently, or heat them in a small saucepan on the stove.
What kind of blueberries should I use? Can I use frozen blueberries?
You can use either frozen or fresh blueberries interchangeably in this recipe. I like using frozen wild blueberries because they are packed with antioxidants, and the small size means you get a nice blueberry flavor in every bite, but regular frozen blueberries work as well. The frozen blueberries will defrost as the oats sit in the fridge, so you won’t need to defrost them before mixing into the oats.
If you go the frozen route, you will want to back off on the added milk just a touch—by about a tablespoon—since the fruit will release some liquid as it defrosts. They will also give the oats a lovely purple color! And if you’d prefer, you can always use fresh blueberries instead, as well.
Can you make substitutions to these overnight oats?
One of the best things about overnight oats is how easy they are to customize! Whether you need them to be vegan, gluten-free, or lower in sugar, the swaps are simple and require no extra effort. Our in-depth overnight oats post has a full range of suggestions, but here are some specific substitutions you can make for these blueberry overnight oats:
- Make it vegan: Use plant-based yogurt in place of the Greek yogurt, and use maple syrup instead of honey.
- Make it sugar-free: Drop the sweetener, make sure to use unsweetened milk, and add 1/2 mashed ripe banana. Or use stevia or monk fruit sweetener in place of the maple syrup or honey, if you prefer.
- Make it gluten-free: Make sure to use certified gluten-free oats.

Hi. I have made this recipe lots of times with oats and love it!! But I have a bag of steel oats I need to use up. Can I substitute it for the rolled oats? Do I need to add more liquid?
Hi, Danielle! Steel cut oats can be used in any of our overnight oats recipes without making any other adjustments. The texture of the finished oats will definitely be chewier, and they’ll be a bit less creamy—but it should still taste just as delicious! Let us know how you like it =)
This is the best recipe for overnight oats. I have tried other recipes, but this one has the best ratio of oats, milk, and yogurt. I make it just as written, except I don’t have chia seeds, so instead I put in a scoop of my Forest Leaf collagen peptides powder. Yum Yum.
Thanks so much, Tammy! We’re so glad you like it, and we really appreciate you taking the time to come back and tell us about it =)
Honestly the best overnight oats recipe I have found! I use half a (very ripe) mashed banana instead of the sweetener, and it is soo good. Thank you so much!
