Lemon blueberry overnight oats are straight-up delicious! Made with whole plant food ingredients and bursting with lemony blueberry goodness, this will become a favorite meal prep recipe in your rotation. This healthy vegan recipe is gluten-free, high in fiber, and made with no added sugar.


Units Scale
  • 1 cup rolled oats (use gluten-free oats, if gluten-sensitive)
  • 1 lemon, zested (not the juice)
  • 2 Tablespoons chia seeds
  • 1/3 cup simple homemade date syrup (or 2 pitted dates, minced)
  • 1 cup plain, unsweetened almond milk
  • 1 cup blueberries
  • 1 teaspoon unsweetened coconut flakes



Zest the lemon with a microplane grater, taking care not to include the white part of the peel. All the lemon flavor is in the yellow part.

Add rolled oats, simple homemade date syrup, lemon zest, chia seeds, and unsweetened almond milk into a mixing bowl. Stir well to combine.

Let the overnight oats mixture sit for 5 or more minutes to set up.

Layer fresh blueberries and overnight oats mixture into a mason jar. We recommend either the 8-ounce or 16-ounce mason jars.

Top the overnight oats mixture with unsweetened coconut flakes.

You can enjoy this delicious "overnight" oats jar immediately or put it in the refrigerator overnight. It will continue to thicken the longer it sits. If it's too thick for you, feel free to hit it with a splash of plant-based milk right before eating.

Leftovers store well in an air-tight container in the refrigerator for up to 3 days.
