Recipe Ingredients

To make delicious blueberry overnight oats, you'll need the following ingredients. This is just an overview, and you can find the full details in the recipe card at the bottom of this post.

GLUTEN-FREE ROLLED OATS - The star of the show! Rolled oats are the base of this recipe. They're perfect for overnight oats because they soften up nicely in the fridge. If you don't have rolled oats, you can use quick oats, but I personally don't recommend them as the texture will be different.
MILK - Any kind of milk will work for this recipe, including cow's milk, or dairy-free milk like almond milk, soy milk, coconut milk, or oat milk. Choose your favorite!
PLAIN YOGURT - Yogurt adds creaminess and tanginess to the oats. You can use Greek yogurt or regular yogurt, and any flavor you like. If you don't have yogurt, you can use extra milk instead.
BLUEBERRIES - Fresh or frozen blueberries work great in this recipe. If fresh berries aren't in season (or are too expensive), use frozen berries instead.
HONEY - Just a touch of honey adds sweetness to the oats. If you don't have honey, you can use maple syrup, agave nectar, or sugar instead.
CHIA SEEDS - Chia seeds help to thicken the texture. They also add a boost of nutrition to the oats, including fiber, protein, and omega-3 fatty acids. If you don't have chia seeds, you can leave them out or substitute them with flax seeds.
LEMON ZEST - A little bit of lemon zest adds a bright, citrusy flavor to the oats. You can also use 1 teaspoon of lemon extract instead. If you don't want a lemon taste, you can leave this ingredient out.
CINNAMON - Cinnamon adds warmth and spice to the oats. If you don't like cinnamon, you can leave it out or substitute it with nutmeg or cardamom.

Toppings and Mix-Ins

When it comes to blueberry overnight oats, the possibilities for toppings and mix-ins are endless. Here are some ideas to add some variety to your breakfast:

NUT BUTTER - Add a dollop of your favorite nut butter, like almond or peanut butter, for an extra protein boost and nutty flavor. You can also try Sunbutter, made from sunflower seeds for a nut-free option.
COCONUT - Sprinkle some coconut flakes into the oats before you mix, or add on top for a twist.
ADDITIONAL BLUEBERRIES - You can never have too many juicy blueberries! Add some extra fresh or frozen blueberries to your oats for more flavor and nutrients.
CHOPPED NUTS OR SEEDS - Add more crunch to the oat mixture or as a topping. You can try chopped walnuts, almonds, pumpkin seeds or sunflower seeds.
GRANOLA - Sprinkle granola on top just before serving for a crunchy texture.

Can I Use Quick Oats or Steel Cut Oats?

Yes, you can use both in replacement of rolled oats (these are the large flake oats), however, the texture will be different. Steel cut oats will create a dense and chewy texture that isn't a personal favorite.

Quick oats do not hold their structure as well, and can produce a more mushy texture. I prefer old-fashioned rolled oats because they are in between both of these texture-wise.

Can I add nuts to my blueberry overnight oats?

Yes, nuts not only add a delicious crunch to your oats, but they also provide a good source of healthy fats, protein, and fiber. Try some almonds, walnuts or pecans!

To add nuts to your oats, simply chop them up and mix them in with your oats before refrigerating them overnight. You can also sprinkle some nuts on top in the morning for an extra crunch.

If you have a nut allergy or prefer not to add nuts to your oats, you can also try adding seeds such as chia seeds, flax seeds, or pumpkin seeds. These seeds are also a good source of healthy fats, protein, and fiber.

How To Make Overnight Oats

Making blueberry overnight oats is incredibly easy. Here are the steps you need to follow with full instructions also in the detailed printable recipe card at the bottom of this post.

SOAK THE OATS - In a bowl, mix together the rolled oats, milk, yogurt, blueberries, honey, chia seeds, lemon zest, vanilla extract, cinnamon, and salt. Stir well and pour into an airtight container or mason jar. Seal with a lid and let the mixture sit in the refrigerator overnight, or at least for 6 hours.
ADD TOPPINGS - In the morning, remove the jar from the refrigerator and stir in any toppings including fresh blueberries. You can also add other toppings, such as nuts, drizzled honey, or cinnamon.

Do I Eat Overnight Oats Cold?

Yes! Most people eat them cold. Just grab a spoon and stir them up, then eat them straight from the container.

If you prefer a pudding-like texture, let the oats sit at room temperature for a few minutes before eating.

Microwaving the oats is always an option if you prefer them a little warm, but be careful not to overcook them, or they will become mushy. Aim for a warm, pudding-like texture that's still slightly chewy.

How To Store

STORE IN THE FRIDGE: Once you've made your oats, store them in an airtight or sealable container in the refrigerator. This will keep them fresh and ready to eat whenever you need them. These will keep up to 4-5 days in the fridge.
SERVING LEFTOVERS: Simply give the creamy oats a stir before serving to redistribute any liquid that may have separated. Add any desired toppings and serve.

Recipe Tips

Make a big batch of this recipe on Sunday night and portion them out into individual containers for the week. This will save you time in the mornings and ensure that you have a healthy breakfast ready to go.
It's important to use a mason jar or a sealable container to keep the oats fresh and prevent any spills. You can also use an airtight container if you don't have a mason jar.
If you don't have time to let the oats soak overnight, you can also make them in the morning and let them sit in the refrigerator for at least 30 minutes. However, the longer the oats soak, the better the texture will be.
