These Blueberry Lemon Overnight Oats are a tasty and easy breakfast! With creamy oats mixed with fresh blueberries and zesty lemon, they are refreshing and fun to eat.
Plus, you can make them the night before—just mix and chill! I love grabbing a jar when I’m in a rush. Breakfast has never been easier or more delicious!
Key Ingredients & Substitutions
Rolled Oats: Rolled oats are perfect for overnight oats because they absorb the liquid nicely, making them creamy. If you only have quick oats, they can work but may lose some texture. Steel-cut oats are not recommended, as they need longer cooking time.
Milk: You can use any type of milk here—dairy, almond, oat, or soy. I often use almond milk for its nutty flavor, but coconut milk adds a nice creaminess too! Just remember, the taste might change slightly based on the milk you choose.
Greek Yogurt: This adds a wonderful creaminess and protein boost. If you’re avoiding dairy, try using coconut yogurt or a nut-based yogurt. You can skip it altogether if you prefer a lighter mix.
Fresh Blueberries: Fresh blueberries are the star of this dish. Frozen can work too, but they might turn mushy once thawed. For a twist, you could also use raspberries or strawberries.
Chia Seeds: They help thicken the mixture and add fiber. If you don’t have chia seeds, ground flaxseed is a good substitute, or you can leave them out entirely for a simpler recipe.
Lemon Zest and Juice: Fresh lemon gives a bright flavor. If you’re in a pinch, bottled lemon juice can substitute but fresh zest is always better! The zest is key for maximizing lemon flavor.
How Do I Keep My Overnight Oats From Being Too Thick?
The texture of overnight oats can vary, and sometimes they can turn out thicker than you’d like. Here’s how to adjust it:
- Start with the usual ratio of oats to liquid (1:1), but if you prefer creamier oats, increase the milk slightly.
- When mixing, ensure everything is well combined to avoid dry pockets of oats.
- If they firm up overnight, just add a splash of milk in the morning and stir until you reach your desired consistency.
- Stirring well before serving helps mix the ingredients again and can improve the texture.
By following these tips, you’ll enjoy a perfect breakfast that’s both delicious and convenient!

Blueberry Lemon Overnight Oats
Ingredients
- 1/2 cup rolled oats
- 1/2 cup milk (dairy or plant-based)
- 1/4 cup Greek yogurt (optional for creaminess)
- 1/2 cup fresh blueberries (plus extra for topping)
- 1 tablespoon chia seeds (optional, for texture)
- 1 1/2 teaspoons lemon zest (from about half a lemon)
- 1 tablespoon lemon juice (freshly squeezed)
- 1 to 2 teaspoons honey or maple syrup (to taste)
- 1 tablespoon sliced almonds (for garnish)
How Much Time Will You Need?
The preparation for these delicious overnight oats takes about 10 minutes. After that, let them chill in the fridge for at least 6 hours or overnight. You’ll have a refreshing breakfast ready to grab in the morning!
Step-by-Step Instructions:
1. Mix the Base Ingredients:
In a mixing bowl, combine the rolled oats, milk, Greek yogurt (if using), chia seeds, lemon zest, lemon juice, and honey or maple syrup. Stir everything together well so that all the ingredients are evenly mixed. This ensures the oats will soak up the flavors!
2. Add the Blueberries:
Gently fold in the fresh blueberries. Take care not to mash them too much; you want to keep them whole for that burst of flavor!
3. Store for the Night:
Transfer the mixture into a clean jar or airtight container. Seal it tightly and place it in the refrigerator overnight or for at least 6 hours. This allows the oats to absorb the liquid and the flavors to blend perfectly.
4. Serve and Adjust Consistency:
In the morning, take your jar from the fridge and give the oats a good stir. If the mixture seems too thick, just add a splash of milk to loosen it up. It should be creamy and smooth!
5. Top It Off:
Add extra fresh blueberries on top, along with a sprinkle of lemon zest, and sliced almonds for a delightful crunch.
6. Enjoy Your Breakfast:
Enjoy your Blueberry Lemon Overnight Oats straight from the jar or transfer them to a bowl if you prefer. It’s a bright and tasty way to kickstart your day!
This refreshing mix balances the tart brightness of lemon with sweet blueberries and creamy oats—a perfect quick and healthy start to your day!
Can I Use Quick Oats Instead of Rolled Oats?
Yes, you can use quick oats, but keep in mind they will absorb liquid faster and may result in a softer texture. If you prefer a chewier bite, stick with rolled oats!
How Long Can I Store Leftover Overnight Oats?
These overnight oats are best enjoyed within 3 days of preparation. Store them in an airtight container in the refrigerator, and give them a good stir before eating.
Can I Add Different Fruits?
Absolutely! You can mix in other fruits like strawberries, raspberries, or chopped bananas. Just be mindful that some fruits might change the texture; for instance, bananas will soften more than blueberries.
Is It Possible to Make a Larger Batch?
Yes! You can easily scale up the recipe by multiplying the ingredients by the number of servings you need. Just make sure you have enough jars or containers to store them in the fridge!
