Ingredients

To make this Blueberry Overnight Oatmeal recipe you will need these simple ingredients:

• Oats. Stick with old-fashioned rolled oats for this recipe. They stay perfectly creamy and chewy after soaking. Quick oats get mushy and steel cut oats can be too firm. (Are oats gluten-free? Learn all about them!)
• Milk. Feel free to use your favorite type of milk. Cashew and oat milks are my go-tos since they are super creamy and taste really good in this recipe. But almond milk, soy milk, and regular milk can all be used.
• Blueberries. You can use fresh, sweet blueberries if they’re in season and available. Otherwise, you can sub in frozen berries.
• Sweetener. Pure maple syrup is the best option, and honey works fantastic, too. In a pinch, brown sugar can be used.
• Chia Seeds. While not absolutely necessary, they add many health benefits and enhance the texture.
• Optional add-ins. Feel free to test the limits! Try things like Greek yogurt, protein powder, spices, or nuts to increase the health benefits and flavor.

Pro Tip: Coconut milk is NOT recommended. This will give your oats a pretty strong coconut flavor instead of a pumpkin spice flavor.

How to Make Blueberry Overnight Oats

The process of making these blueberry muffin overnight oats recipe is relatively simple:

Add the Blueberries to the Jar

Stick with 8-ounce jars when making this recipe because they are easy to find and will fit an entire serving of overnight oats. A wide mouth Mason jar is best.

Add the blueberries to the bottom of the jar. Pop it in the microwave for about a minute to soften them. The jammy blueberries give the oatmeal a pudding-like texture.

Combine Remaining Ingredients

Pour the oats, chia seeds, and milk into the jar with the softened blueberries.

Gently stir the mixture with a spoon until everything is well combined.

Refrigerate to Set

Place the lid on the jar and tighten. Set it in the fridge.

Let it chill for at least 4 hours, but it is best if left all night.

Serve these overnight oats with fresh blueberries, roasted pecans, or spices.

Meal Prep & Storage

• To prep and store: The recipe is perfect to prepare entirely the day before. After mixing, it will keep in the refrigerator in an airtight, resealable container or covered tightly with plastic wrap for up to 3 to 4 days. However, the oatmeal will get mushy after the first 24 hours. To ensure the best texture every morning of the week, do not add the milk to the jar until the night before serving.
• To freeze: Freezing is not recommended. The texture of the oats will not be the same and instead will be too watery.

Are overnight oats healthy?

This blueberry overnight oats recipe is both easy and healthy. Oatmeal is a good-for-you carb that keeps you full all day and has so many nutritional benefits. It also is a great source of fiber. Just be careful about add-ins, as those can increase the sugar and calorie count, making the dish less healthy.

How long do overnight oats last?

Overnight oats can last for up to 3 to 4 days, but they are best enjoyed within 24 hours. They will start to get mushy after too long. If you’d like, you can mix everything in the jar except for the milk, which you can add the night before serving.

Do I serve overnight oats warm or cold?

The temperature is your choice! This recipe is delicious both warm and cold. If you choose to heat them up, use the microwave for about a minute, adding in extra milk to get a creamy texture if needed.
