These blueberry lemon overnight oats have been on a heavy breakfast rotation at my house for years! Lemon zest in creamy overnight oats is honestly something special - almost like a creamy lemon dessert situation (and similar to my blackberry lemon baked oatmeal, which totally tastes like a treat). Add in some plump and juicy blueberries, and you've got yourself an antioxidant-rich, delicious, and filling breakfast recipe. Perfect for busy mornings!

Ingredients

Oats, blueberries, Greek yogurt, milk, vanilla extract, chia seeds, lemon, salt, and honey on gray and white surface.
  • Rolled oats - Oats are the main ingredients in this recipe! If gluten free, be sure to use oats labeled as certified gluten free.
  • Chia seeds - Chia seeds add fiber and protein, and they soak up some of liquid to create a creamy texture.
  • Salt - Balances out sweetness and enhances overall flavor.
  • Greek yogurt - Yogurt provides protein and incredible creaminess! I love using plain Greek yogurt (2% or whole milk) or Siggi's vanilla skyr (SO good!).
  • Milk - Use your favorite! Milk will be the main liquid that gets soaked up by the oats.
  • Honey - Just a touch for a bit of sweetness.
  • Lemon - We'll use both the juice and zest for the best lemon flavor.
  • Vanilla extract - Add delicious vanilla flavor.
  • Blueberries - For topping your oats! Blueberries and lemon are super tasty together.

See the recipe card for full information on ingredients and quantities.

Substitutions & Variations

Below are some easy ingredient substitutions and variations to help you adapt this recipe for your needs and tastes!

  • Plant-based - Use plant-based yogurts and milks, and replace honey with agave or maple syrup to keep this recipe plant-based.
  • High protein - Whether it's plant-based or not, choose high protein milks and yogurts to get the biggest protein bang for your buck! You could also stir in a vanilla protein powder. My protein overnight oats recipe shows you all the tips on how to increase protein in any overnight oats.
  • Toppings - Toppings are the MOST fun! In addition to blueberries, I love adding a bit of crunch with chopped almonds, granola, or coconut flakes. You could also drizzle on some almond butter or add another dollop of yogurt for creaminess.
  • Frozen blueberries - When berries aren't fresh or are just too expensive, use frozen! Thaw blueberries overnight in a separate container in the fridge. In the morning, drain some of the liquid off and top your oats.

How to Make Blueberry Lemon Overnight Oats

All overnight oats ingredients added to clear glass bowl, not fully mixed yet, with spoon resting in bowl. The bowl sits on a gray and white surface.

Step 1: Combine all overnight oats ingredients in a bowl except for the blueberries.

Step 2: Stir together until mixed into an even consistency where everything is evenly distributed. Tightly cover the overnight oats mixture and place in the fridge overnight.

Step 3: When ready to eat, divide into to two servings and top with fresh blueberries and any other desired toppings!

Hint: When using the same lemon for juicing and zesting, I like to zest it while the lemon is still whole, and then cut and juice it. This makes for easier handling and is easier to hold the lemon against your microplane so that you don't slip.

Top tip

I love to make the overnight oats in the same container I chill them in! Use a medium-large-sized glass bowl or container with some sort of airtight lid. Mix your overnight oats, cover, and pop it right in the fridge. Done!

Recipe FAQs

Can I use frozen blueberries instead of fresh?

Of course! Using frozen blueberries in overnight oats is delicious. I recommend thawing the frozen blueberries separately in the fridge overnight, and then topping your oats when ready to eat.

How long do overnight oats last in the fridge?

I recommend enjoy your overnight oats within five days.

How do I store leftover overnight oats?

Store your overnight oats in the fridge for up to five days in jars with lids or airtight containers. Most of the time I recommend storing any fruit or toppings separately and adding them to your overnight oats right before eating. Fresh blueberries, however, stand up pretty well to creamy oats in the fridge overnight, so feel free to do what you like best! I still usually just top my oats the next day regardless.

Do overnight oats freeze well?

I've tested freezing overnight oats, and they do actually freeze and thaw pretty well! With this recipe, I do prefer add fresh blueberries on later instead of freezing them into the oats, though I'm sure it would taste fine either way.

Description

These blueberry lemon overnight oats are a healthy and filling breakfast recipe! They're extra creamy, high in protein, and bursting with bright lemon and juicy blueberries. Prepare them the night before, and breakfast will be ready when you wake up!


Ingredients

Units Scale
  • 1 cup old-fashioned rolled oats
  • ½ tbsp chia seeds
  • ¼ teaspoon salt
  • 1 cup milk of choice
  • ⅓ cup plain Greek yogurt
  • 1 tsp vanilla extract
  • juice and zest of 1 lemon
  • ½ tbsp honey
  • 1 cup fresh blueberries


Instructions

  1. Combine ingredients. In a bowl or base of an airtight container, combine all ingredients except blueberries. Stir until an even mixture forms, and all ingredients are evenly distributed.
  2. Chill. Cover the bowl tightly and chill the mixture overnight.
  3. Serve. In the morning, divide the oats into two servings. Top each with ½ cup blueberries and any other desired toppings, or save a serving for later. Enjoy!

Notes

  1. Chilling time. If using rolled oats (recommended for this recipe), I like the texture best when it's been chilled overnight because the oats have maxed out their absorption of delicious milk, yogurt, and flavors. If you want or need to eat them sooner, 4 hours is typically the minimum chilling time I recommend.
  2. Storage container. Overnight oats is one of those recipes that I actually love to make in the same container I store it in (less dishes = yay!). I love to use any glass storage container that's at least a 4-cup size with an airtight cover. This way, you can stir, cover, and pop it in the fridge.
  3. Toppings. This is the best part of overnight oats, so have some fun with it! Blueberries are of course a topping for this recipe, but coconut flakes, blueberry jam, almonds, more chia seeds, scoop of yogurt, granola, or other nuts/seeds will add delicious flavor and texture.
