  • Total Time: 8 hours 5 minutes (includes soaking time)
  • Yield: 2 servings 1x

Ingredients

Scale
  • 1 cup rolled oats (old-fashioned oats)
  • 1 cup milk (dairy or non-dairy)
  • ½ cup Greek yogurt (plain or vanilla)
  • 1 cup fresh or frozen blueberries
  • 2 tablespoons maple syrup or honey
  • 1 tablespoon chia seeds (optional but recommended)
  • 1 teaspoon vanilla extract
  • Pinch of salt

Optional Toppings:

  • Extra fresh blueberries
  • Sliced almonds or chopped walnuts
  • Shredded coconut
  • Drizzle of nut butter
  • Granola for crunch
  • Lemon zest

Instructions

  • Combine the base ingredients: In a medium bowl or directly in your storage jars, add the rolled oats, milk, Greek yogurt, maple syrup, chia seeds (if using), vanilla extract, and salt. Stir everything together thoroughly until well combined and no dry oats remain at the bottom.
  • Add the blueberries: Gently fold in ¾ cup of the blueberries, reserving the remaining ¼ cup for topping. You can lightly mash a few blueberries against the side of the bowl if you want more blueberry flavor distributed throughout.
  • Divide into jars: If you mixed everything in a bowl, divide the mixture evenly between two mason jars or airtight containers. If you mixed directly in jars, just make sure the lids are secure.
  • Refrigerate overnight: Cover the jars tightly and refrigerate for at least 6 hours, but preferably overnight (8-12 hours). The oats will absorb the liquid and soften to a creamy, pudding-like consistency.
  • Add toppings and serve: In the morning, give your oats a good stir. Add your reserved fresh blueberries and any other toppings you desire. You can eat them cold straight from the fridge, or warm them in the microwave for 30-60 seconds if you prefer a warm breakfast.

Notes

  • Texture preference: If you like thinner oats, add an extra 2-3 tablespoons of milk in the morning. For thicker oats, reduce the milk slightly or add an extra tablespoon of chia seeds.
  • Sweetness level: Adjust the sweetener to taste. Blueberries vary in sweetness depending on the season, so taste and adjust accordingly.
  • Make it vegan: Use plant-based milk, coconut yogurt or skip the yogurt entirely, and choose maple syrup instead of honey.
  • Protein boost: Add a scoop of vanilla protein powder or an extra ¼ cup Greek yogurt for more protein.
  • Best within: These oats stay fresh for up to 5 days in the refrigerator, making them perfect for weekly meal prep.
