⭐️ Why You Should Try It

  • Healthy and nutritious. What we love about these overnight oats is that they are made with wholesome ingredients and naturally sweetened. The blueberry flavor really shines, giving them a fresh and fruity flavor that is hard to resist! They are super creamy and not overly sweet.
  • Quick and simple. This recipe requires only 10 minutes and 7 simple ingredients to prepare. You can quickly make it after dinner to have your breakfast ready for the following morning. Plus, no cooking is needed!
  • Great for meal prep. Overnight oats are also a great meal prep option, as they keep very well in the refrigerator and can be enjoyed throughout the week as breakfast, snack, or post-workout. We even enjoy them as dessert, topped with shaved chocolate!

📘 What Are Overnight Oats

Overnight oats are a way of preparing oatmeal that consists of soaking either rolled or quick oats in some liquid, such as water, milk, and/or yogurt, for a few hours in the refrigerator. This method allows the oats to rehydrate and soften.

Overnight oats are convenient as they can be made as a big batch and enjoyed straight from the refrigerator without the need to cook them.

Ingredients like quick oats, blueberries, coconut yogurt, and maple syrup.

🫐 Ingredient Notes

Here is what you will need to make these overnight oats:

  • Oats – If you prefer chewier oatmeal, use rolled oats. Otherwise, quick oats work great.
  • Blueberries – You can use fresh or frozen blueberries. Be aware that frozen blueberries will give your oats a more vibrant purple color.
  • Plant-based milk – Any plant-based milk will work. You can use almond, cashew, coconut, or soy milk.
  • Yogurt – The addition of yogurt to the oats gives them a hint of tanginess and a creamier consistency. We went with unsweetened coconut yogurt but any vegan yogurt will work.
  • Maple syrup – To sweeten. We recommend using a liquid sweetener such as maple syrup, agave, or honey if you are not vegan. Granulated sugar will not dissolve well in cold liquids.
  • Lemon juice – Lemon juice does two things. It not only adds a tangy flavor to the oats but also helps them retain their bright and vivid purple color. We tested with and without lemon juice and observed that the oats with no lemon juice turned pale blue over time, while the ones with lemon juice retained their purple color for several days.
  • Vanilla extract – For a floral and fresh aroma. Use high-quality store-bought vanilla extract or homemade vanilla extract.

🥣 How to Make It

  1. Blend the blueberries. Add the blueberries to a high-speed blender. Pour in the plant-based milk, yogurt, lemon juice, maple syrup, and vanilla extract. Blend for 5-10 seconds or until smooth.
  1. Combine with the oats. Add the oats to a large mixing bowl and pour in the blended blueberries.

  1. Stir to combine. Using a large spoon or spatula, stir to combine the oats with the blended blueberries. The mixture will look very liquid. This is normal as the oats will soak up the liquid overnight.
  2. Transfer to jars. Finally, transfer the blueberry oats to individual jars and close with the lids. Note: This recipe makes 3 small portions or two larger ones. This is totally up to you.
  3. Chill overnight. Once you have filled the jars, place them in the refrigerator and let them chill overnight or for a minimum of 6 hours. The following morning, all you have to do is add your favorite toppings and enjoy!

📔 Tips

  • Use good blueberries. Not all blueberries are equal, and since they are one of the main ingredients in this recipe, we recommend avoiding using cheap blueberries, as they tend to have a bland flavor and are not very sweet. Instead, use sweet fresh blueberries when in season or high-quality frozen ones.
  • Add extra blueberries. If you want more flavor and texture, do not blend all of the blueberries. You can save approximately 1/3 cup of blueberries and slightly mash them before incorporating them into the oats.
  • Double or triple the batch. The recipe we are giving here serves 2-3. You can easily double or even triple it if you want to serve more people or have enough oatmeal to enjoy throughout the week.

🍫 Variations

You can find below a few suggestions to customize these blueberry overnight oats:

  • Protein Power: Add 2-3 tablespoons of your favorite plant-based protein powder and an extra splash of milk to make protein-packed oats.
  • Chocolate Lover: Stir in 2-3 tablespoons of mini chocolate chips for extra texture and a chocolatey flavor.
  • Blueberry & Banana: Blueberries and bananas are a perfect match. Feel free to add half of a sliced or diced banana to your oats.

🥜 What to Serve It With

These blueberry overnight oats are not only perfect for a quick breakfast but also make a great afternoon snack, post-workout snack, or dessert! Looking for ways to customize them? Here are a few of our favorite options:

  • Nut butter: Peanut butter, cashew butter, or almond butter are great options to add healthy fats and plenty of nuttiness to your oats.
  • Nuts: Either whole or crushed, pecans, peanuts, or cashews will add some crunch.
  • Seeds: Pumpkin seeds, chia seeds, sunflower seeds, or hemp hearts.
  • Fresh fruits: Garnish your oats with extra blueberries, diced peaches, or sliced bananas for extra sweetness.

❄️ Storing & Freezing

  • To store: These overnight oats can be stored in the refrigerator for up to 5 days.
  • To freeze: You can freeze leftovers for up to 2 months. Simply transfer them to a freezer-safe container or bag. Thaw overnight in the refrigerator.

💬 FAQ

Can I omit the lemon juice?

Yes, you can omit the lemon juice. Just be aware that your oats won’t keep their vibrant color.

Can I heat these overnight oats?

Sure! You can warm the oats in a saucepan over medium heat for a few minutes or microwave them for 2-3 minutes.

We hope you will love these blueberry overnight oats! They are super fresh, fruity, and nutritious. They taste so amazing that we are sure you will love them as a dessert too!
