Blueberry lemon overnight oats are a fresh and tasty breakfast that’s easy to prepare! With oats, juicy blueberries, and a zesty lemon kick, they’re a perfect start to your day.
I love waking up to this delicious combo waiting for me in the fridge. Plus, you can top them with extra fruit or nuts for a fun twist—perfect for the busy mornings! 🍋💙
Key Ingredients & Substitutions
Old-fashioned rolled oats: These are perfect for a creamy texture. If you don’t have them, quick oats can work, but they may be softer. Steel-cut oats won’t soften enough overnight, so stick with rolled oats for best results.
Milk: Use any milk you like! Almond, oat, or soy milk are great non-dairy options. If you’re not dairy-free, regular milk works just fine. I personally love almond milk for its slightly nutty flavor.
Greek yogurt: This is optional, but it adds creaminess and protein. You can skip it if you want a lighter version or substitute with a dairy-free yogurt. I’ve used coconut yogurt before, and it’s delicious!
Chia seeds: These add nutrition and help thicken the oats. Flaxseeds can also work as a substitute if you have them on hand.
Blueberries: Fresh is best for this recipe, but frozen blueberries work too. Just add them straight from the freezer; they’ll thaw overnight in the mixture!
How Do I Make Sure the Oats Are Perfectly Creamy?
Getting the right texture for overnight oats can be tricky. A few tips can help you achieve that creamy consistency:
- Use a good balance of oats to liquid. The 1:1 ratio of oats to milk is spot-on.
- Mix the ingredients well before refrigerating to ensure even soaking.
- If it’s too thick in the morning, just add a bit more milk and stir. This makes it just right.
Remember, the longer they soak, the creamier they become, so overnight is best! Enjoy your breakfast in a jar!

Blueberry Lemon Overnight Oats
Ingredients You’ll Need:
Base Ingredients:
- 1/2 cup old-fashioned rolled oats
- 1/2 cup milk (dairy or any plant-based milk)
- 1/4 cup plain Greek yogurt (optional for creaminess)
- 1 tablespoon chia seeds
- 1 to 2 teaspoons honey or maple syrup (adjust for sweetness)
- 1/2 teaspoon vanilla extract
- Zest of half a lemon
- 1 tablespoon fresh lemon juice
- 1/2 cup fresh blueberries (plus extra for topping)
- 2 tablespoons sliced almonds (for topping)
- Lemon slice (for garnish)
How Much Time Will You Need?
This recipe takes about 10 minutes to prepare, and then you’ll need to let it chill in the fridge overnight (or for at least 6 hours) so the oats soak up the delicious flavors. It’s a quick prep for a tasty morning surprise!
Step-by-Step Instructions:
1. Mix All the Base Ingredients:
In a mixing bowl, combine the rolled oats, milk, Greek yogurt (if you’re using it), chia seeds, honey or maple syrup, vanilla extract, lemon zest, and lemon juice. Give everything a good stir until all the ingredients are well mixed.
2. Add in the Blueberries:
Gently fold in 1/2 cup of fresh blueberries into your mixture. Be careful not to crush them too much; you want some whole berries for a burst of flavor!
3. Store for the Night:
Pour the mixture into a clean jar or airtight container. Make sure to give it a good seal, then pop it into the fridge to chill overnight. This allows the oats and chia seeds to soak up all the yummy flavors.
4. Ready to Enjoy:
The next morning, take your oats out of the fridge and give them a good stir. If it looks too thick for your liking, feel free to add a splash of milk to loosen it up.
5. Top It Off:
Add some extra fresh blueberries on top and sprinkle with sliced almonds for that perfect crunch. Don’t forget to garnish with a lemon slice on the jar rim—it makes it look super pretty!
6. Savor the Flavor:
Enjoy your delicious blueberry lemon overnight oats straight from the jar or transfer them to a bowl if you prefer. Happy eating!
This recipe is a delightful blend of creamy oats, tangy lemon, and sweet blueberries, making it an easy and refreshing breakfast that you’ll love. Enjoy every bite!
Can I Use Different Sweeteners?
Absolutely! If you prefer, you can use agave syrup, stevia, or even a mashed banana for natural sweetness. Just adjust the quantity to taste depending on the sweetener you choose, as they can have varying levels of sweetness.
What if I Don’t Have Chia Seeds?
No problem! If you don’t have chia seeds, you can simply omit them. They help with thickening but aren’t essential. Alternatively, you could use flaxseeds for similar benefits!
How Do I Store Leftover Oats?
Leftover oats can be stored in an airtight container in the refrigerator for up to 3 days. You might need to add a bit of milk to refresh them before serving, as the oats will continue to absorb liquid.
Can I Use Other Fruits?
Yes! Feel free to mix it up with other fruits like strawberries, raspberries, or bananas. Just make sure to adjust the quantities according to your preference for flavor and sweetness!
