High-Protein Lemon Blueberry Overnight Oats (great for meal prep!)

Is there anything more “spring” than a classic lemon-blueberry combo? I think not! Every year when March rolls around, I start dreaming up all 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 had to re-share these high-protein lemon blueberry overnight oats to help ring in the new season. 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.
• 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 extra 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, and omega-3s, and helps thicken the oats to make them creamy.
• 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 be gritty instead of nice and creamy.

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 — hence the name!)
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.

• 1 to 2 tablespoons pure maple syrup, to taste**

• Mix-ins:

Instructions

• In a medium bowl, add lemon zest, lemon juice, yogurt, milk, pure maple syrup (see notes below), and almond and vanilla extracts. Whisk together until well combined. Stir in chia seeds, and oats until well combined. Fold in the blueberries. I love to use frozen blueberries because it will give the overnight oats a gorgeous purple hint!

Recipe Notes

*To make dairy-free / vegan: Use your favorite dairy-free vanilla or coconut yogurt, and be sure to use dairy-free milk.
**I find that if you use vanilla yogurt, it is sweet enough on its own, but if you use plain, you will need to add 1 to 2 tablespoons of pure maple syrup.
