Ingredients You’ll Need

Ingredients needed to make blueberry overnight oats.

blueberries — you can use fresh or frozen blueberries! It’s more budget-friendly to use frozen blueberries, and you don’t have to worry about the blueberries not being in season.
rolled oats — make sure you are using old-fashioned rolled oats. Instant oats and quick oats do not hold up as well, so I do not prefer the texture.
chia seeds — chia seeds come in both black and white seeds, but there is no difference in nutritional content. They’re also an excellent source of plant-based protein! When they absorb the milk or water, it helps thicken the overnight oats.
milk or water — you can use any water or milk of your choice, from cow’s milk to non-dairy milk. Sometimes when I run out of milk, water is an easy swap like my overnight oats with water recipe. You can also use a combination of both!
maple syrup — you can also use honey if you prefer.
vanilla extract — I always recommend using real vanilla extract and not artificial extract. Don’t have any? Skip it! No biggie.
yogurt — to help with the creaminess, the yogurt works together with the chia seeds to give the blueberry overnight oats a creamy texture. If you don’t have yogurt, applesauce or mashed bananas can help with giving the oats their creamy texture. You can use flavored yogurt, such as vanilla, to add some extra flavor to the overnight oats. Blueberry yogurt is a nice addition to the overnight oats as it adds even more blueberry flavor. You can use regular or plant-based yogurt.
salt — just a pinch to help enhance the flavors in the overnight oats.

How to Make Blueberry Overnight Oats

Place blueberries and maple syrup in a small saucepan. Cook over medium heat for 1 minute until blueberries just begin to soften and release juices.
Mash lightly if desired. Let cool and store in the fridge until ready to use with the overnight oats.

Recipe Tips and Notes

Don’t want to cook down the blueberries? Simply stir it into the overnight oats! Even better if they’re frozen, as they’ll thaw overnight in the fridge and give the overnight oats a nice color. Alternatively, you can stir in some blueberry jam!
You can add a couple of spoonfuls of nut butter to the overnight oats to add extra protein and flavor.
You can cook the blueberries even longer if you prefer a thicker and more syrupy blueberry sauce. You can continue to mash it as well.
A sprinkling of lemon zest would make for a wonderful addition, as lemon and blueberries go so well together.
For an on-to-go meal, mason jars are great. 16-ounce wide-mouth mason jars are great if you plan on adding toppings, so you don’t spill anything. I also LOVE a good weck jar. They’re so pretty.
You can add extra chia seeds to make the overnight oats even thicker.

Make Ahead Tips

Meal prep: store the overnight oats without any toppings in an airtight container for up to 5 days in the fridge.
Freezer: to freeze overnight oats, portion out the oats in small containers, then freeze! Thaw the overnight oats in the fridge for 6-8 hours/overnight before you’d like to eat them. You can store blueberry overnight oats in the freezer for up to 2 months.

What are overnight oats?

Overnight oats are a no-cook method of making oatmeal! It’s made by soaking rolled oats in some liquid overnight, so they become soft and digestible.

Do you eat overnight oats hot or cold?

If you’re not a fan of a cold breakfast, no biggie! You can microwave the blueberry overnight oats until warmed through before enjoying them for breakfast.

Are overnight oats healthy?

I would consider this blueberry overnight oats recipe to be healthy as the ingredients are rich in fiber, protein, and antioxidants. They also contain a wide range of vitamins and minerals!

Can you use steel-cut oats for overnight oats?

While you can use steel-cut oats, keep in mind that steel-cut oats will need to be soaked longer, and the texture will be dense and chewy in comparison. This blueberry overnight oats recipe, in particular, uses rolled oats, so I recommend following the recipe if this is your first time making overnight oats.
