How to Make it as Overnight Oats

To make this recipe as overnight oats, you’ll have to cook the rhubarb separately first. Unless you don’t mind eating it raw that is. To cook it, simply add it to a small sauce pan with a splash of water and cook over medium heat until softened, now it’s ready to use in strawberry rhubarb overnight oats.

For the overnight oats, add the cooked rhubarb and the rest of the ingredients to a container and shake or still well to combine. Place in the fridge overnight and it will be ready to enjoy in the morning.

Recipe Tips and Substitutions

  • This can be made with water or any plant-based milk.
  • You can use ground flax instead of chia seeds.
  • See tips below for how to make it as overnight oats.
  • For sweetening options, sweeten to taste using 1-2 tbsp maple syrup, agave, coconut sugar, organic cane sugar, brown sugar or sucanut.
  • For sugar-free oatmeal, sweeten with powdered stevia or liquid stevia drops. I use either 10 drops of liquid stevia or 1 packet of powdered stevia. Monk fruit sweetener would also work as a sugar-free option.
