I meal prep a batch of overnight oats for the entire week and am always looking for new flavors to keep things fun. These Blueberry Lemon Overnight Oats are one of our favorites.
I love the blueberry lemon flavor combo, and that I can use fresh or frozen blueberries. Plus, they're packed with protein and wholesome oats, and easy to grab for a quick breakfast or snack anytime.
🍋Ingredients
See recipe card at the bottom of the post for the full list of ingredients and exact amounts.
- Oats. Old-fashioned rolled oats and quick steel cut oats are the best oats for overnight oats. Quick oats get very soft (my husband likes these, I don't), and instant oats just turn to mush.
- Blueberries. Use fresh or thawed frozen blueberries. Frozen blueberries create that pretty purple color in the photos.
- Plain Greek yogurt. I use nonfat Chobani or Aldi's whole milk Greek yogurt. Both have a thicker texture, so if yours is thinner, use a little less milk. Vanilla Greek yogurt would also be delicious; adjust the sweetener accordingly.
- Pure maple syrup or honey. Sweeten to taste. Honey is sweeter than maple syrup, so you may need less.
- Dairy or non-dairy milk. Use your favorite milk. I use unsweetened vanilla almond milk, but regular dairy milk, soy milk, oat milk, or other plant-based milks are also fine.
- Lemon zest. Zest adds all the lemon flavor. I don't use the lemon juice, as it only adds more liquid. Save the zested lemons for water or tea.
- Toppings. Before serving, swirl with a couple of teaspoons of blueberry jam and top with fresh fruit, toasted nuts or coconut, and more lemon zest.
🫐Variations or Substitutions
- Fruit. Swap out all or some of the blueberries for fresh or frozen strawberries or raspberries.
- Jam: Swap honey or syrup with a couple of teaspoons of preserves.
- Nut butters: Stir in peanut, almond, cashew, sunflower seed butter, or PB powder.
- Chia seeds: Add 1 tablespoon of chia seeds and a couple more tablespoons of milk. You may need to add more milk the next day, too.
- Flax seeds: Mix in 1 tablespoon ground flax; may need a splash of milk before serving.
- Protein powder: For a boost of extra protein, stir in your favorite protein powder. Adjust the liquid accordingly, as some thicken while others loosen.
🥣How to Make Lemon Blueberry Overnight Oats
Step 1. Mash the blueberries in a small bowl or mason jar. Stir in the rest of the ingredients. Cover and refrigerate 4-6 hours or overnight.
Step 2. Before eating, give the oats a good stir. Add more milk or yogurt, if needed. Top with fresh fruits, toasted nuts, and extra lemon zest.
👉Helpful Hint: Adjust consistency. Too thick? Thin with a splash of milk. Too thin? Stir in yogurt, drain the excess liquid, or add a couple more tablespoons of oats and allow 4 hrs to absorb.
✅Top Tips
- Best oats for overnight oats. Rolled oats soften perfectly overnight. Steel-cut quick oats are also a great option for a chewier bite.
- Control sweetness. Adjust sweetness to taste by using more or less maple syrup, honey, or jam. Or leave it out entirely.
- Add chia seeds. For thicker oats, stir in a tablespoon of chia seeds with the oats. Increase the milk and yogurt by two tablespoons each. Add more as needed the next day.
🎁Storage
- Storage: Keep in an airtight container in the refrigerator for up to 4 days.
- Meal prep: Make a batch of individual servings for easy grab-and-go breakfasts.
- Store toppings separately. Keep crunchy toppings or fresh fruit in a small container until serving.
