These Lemon Blueberry Overnight Oats are an easy make-ahead breakfast full of bright, fresh flavor.

Warm spring days call for light, refreshing breakfasts. These lemon blueberry overnight oats combine citrus brightness with juicy blueberries for a simple, make-ahead meal that’s perfect for busy mornings.
Ingredients
- 1 cup milk of choice (unsweetened soy milk or 1% milk recommended)
- 1 tablespoon lemon juice
- 2 teaspoons lemon zest (about 1 lemon)
- ½ cup lemon Greek yogurt
- 1 teaspoon chia seeds
- 1 cup rolled oats
- ½ cup fresh blueberries (or frozen)
Instructions
In a medium bowl, whisk together the milk, lemon juice, lemon zest, lemon Greek yogurt, and chia seeds until smooth. Stir in the rolled oats and blueberries until evenly combined. Transfer the mixture to a jar or bowl with a tight-fitting lid, cover, and refrigerate for at least 4 hours or, ideally, overnight.

Pro Tips
- For a stronger lemon flavor, add ¼ teaspoon lemon extract.
- Frozen blueberries work well and will tint the oats purple. If chilling for only 4 hours, thaw frozen berries first; if refrigerating overnight, you can add them frozen.
- For an herbaceous twist, stir in a teaspoon or two of finely chopped fresh basil before serving.
FAQs
How long will these oats keep?
Stored in a sealed container in the refrigerator, the oats keep for 3–4 days.
Can I eat them warm?
Yes. Warm in a microwave-safe bowl in 30-second intervals until just heated through. Avoid overheating to prevent the yogurt from separating.
Can I make this vegan?
Use plant-based milk and a dairy-free lemon yogurt. If lemon-flavored plant yogurt isn’t available, increase zest by a teaspoon and sweeten with 1–2 teaspoons of maple syrup or agave.
