High-Protein Lemon Blueberry Overnight Oats

Is there anything more “spring” than a classic lemon-blueberry combo? I think not! Every year when March rolls around I start dreaming up aaall of the spring recipes, and I just can’t resist adding blueberries to all of my fresh lemon recipes.

Pancakes? Duh. Muffins? Absolutely. Cake? Hell yes. Baked oatmeal? You bet.

I haven’t shared a new overnight oats recipe in awhile and I almost forgot just how good (and EASY) they are to make. So, you know I had to give you lemon blueberry overnight oats. These cute jars are packed with over 14 grams of protein, are oh-so-creamy, and filled with fresh, perfectly sweet flavors. Truthfully they taste like cake or another delicious spring baked good, and I know you’re going to be obsessed.

Everything you’ll need to make these lemon blueberry overnight oats

This easy lemon blueberry overnight oats recipe uses super simple ingredients, and the oats seriously taste like your favorite spring baked treat. Here’s what you’ll need to make them:

• Lemon: we’re adding both fresh lemon juice and lemon zest to these oats for the perfect amount of brightness.
• Yogurt: feel free to use plain or vanilla Greek yogurt, which adds creaminess and plenty of protein. Or use a coconut yogurt to keep them dairy free.
• Milk: you’ll need a little milk to help thicken the oats. Feel free to use any milk you’d like!
• Maple syrup: if you’re using plain Greek yogurt I recommend adding a little maple syrup for extra sweetness. Vanilla yogurt is typically sweeter, so you may not need to add any added sweetener.
• Flavor boosters: we’re adding both vanilla extract and almond extract to these oats to bring out that cake-like flavor. Learn how to make your own vanilla here!
• Chia seeds: just a tablespoon of chia seeds adds extra protein, fiber, omega-3s, and helps thicken the oats.
• Oats: the star of the show? Rolled oats, of course! Be sure to use certified gluten-free rolled oats if you need to keep this recipe gluten free.
• Blueberries: feel free to use fresh or frozen blueberries in this overnight oats recipe. Frozen blueberries will give the oats a fun purple color! You’ll get a lovely boost of vitamin c and antioxidants.

Can I use steel cut oats?

Unfortunately, no, I cannot recommend using steel cut oats because they will not absorb as much liquid as rolled oats so the texture will not turn out right.

Customize your overnight oats

Yes, you can make a few simple ingredient swaps to make these blueberry lemon overnight oats your own!

• Keep them dairy free & vegan: simply use your favorite coconut yogurt or dairy-free yogurt. Then be sure to use non-dairy milk such as almond milk.
• Try a new berry: I love the combination of lemon and blueberry together, but you could also use other fresh or frozen berries like strawberries or raspberries.
• Add extra mix-ins: feel free to add a tablespoon of flaxseed meal or hemp seeds for another boost of nutrition. You could also add a scoop of your favorite plain or vanilla protein powder, or collagen peptides for even more protein! You may just need to add extra milk to thin.

Have fun with your favorite toppings

These oats are delicious on their own, but I love to add things like:

• Blueberry jam (try layering it in your mason jar!)
• Homemade granola (I LOVE my healthy granola recipe!)
• Lemon zest
• Extra fresh blueberries

How to make lemon blueberry overnight oats

1. Whisk the wet ingredients. In a medium bowl whisk together all of your wet ingredients.
2. Add the dry. Stir in the chia seeds and oats until well combined, then fold in the blueberries.
3. Let them chill. Cover the bowl with plastic wrap and place in the fridge for at least 4 hours (overnight works great!)
4. Divide the oats. Divide the oatmeal mixture between two 12-ounce mason jars with lids, laying a spoonful of blueberries or blueberry jam in the middle, if you’d like.
5. Top & enjoy! When you’re ready to eat, top your serving with granola, lemon zest, and more blueberries if you’d like. Then enjoy!

How to store overnight oats

These lemon blueberry overnight oats will stay good in the refrigerator in an airtight container or mason jar for up to 5 days. This makes them super portable and easy to enjoy on the go during busy weekdays. Just be sure to give them a good stir if they’ve been sitting for a couple of days.

Can I eat them warm?

Sure! I like to eat overnight oats cold, but if you prefer your oats warm you can feel free to heat them up in the microwave before eating them. Give them a good stir after heating them, too, so that the consistency remains the same.
