Lemon Banana Overnight Oats Tips:

Banana and lemon overnight oats will taste much better if you follow these handy tips that are guaranteed to keep your oatmeal fresh and enjoyable every time. Incorporate each of the helpful hints so that you level up the no cook oatmeal.

  • Banana: Bananas are packed with wholesome nutrition and a ton of flavor. From dietary fiber to essential vitamins and minerals, bananas are a beneficial compliment to a well balanced diet. 
  • Lemon: Lemon juice is a powerful immunity booster. While fresh lemon juice can be purchased in the juice aisle at the market, it’s best to use a whole lemon because the taste is much fresher and you can also use the zest of the lemon.
  • Oats: Rolled oats are preferred for making this recipe extra smooth and creamy. Steel-cut oats and quick oats are not optimal for soaking. Steel-cut oats result in a chewy texture, while quick oats get too mushy when soaked overnight. 
  • Liquid ratio: Oats soak up the liquid when combined overnight, so adding enough liquid is important. If necessary, add a splash of liquid to thin the consistency before serving. For a porridge-style oatmeal, 2:1 ratio of liquid to oats works best, but add-in ingredients largely affect this ratio. 
  • Chia seeds: Chia seeds absorb extra liquid, therefore the oatmeal may thicken too much overnight. Simply adjust with a quick stir and add an extra splash of liquid. Chia seeds plump into tiny jelly like boba balls when they hydrate. They provide an interesting mouthfeel because each one will pop in your mouth when you chew on them. Stir the chia seeds well so that they don’t clump together when preparing the no cook oatmeal.
  • Vegan: Replace the honey with a natural sweetener like maple syrup, coconut sugar or brown sugar. In addition, use a dairy free milk and yogurt alternative for this recipe to be vegan.
  • Gluten free: Even though oat are gluten free, certified whole grain oats are recommended if you follow a strict wheat free diet.
  • Protein powder: A scoop of protein powder will boost the available nutrition. Select your favorite brand of unflavored or vanilla for a complimentary taste.
  • Give it a stir: Give the no cook oats a good stir before adding any toppings and serving. Combine the soft layer at the bottom with the crunchy parts of top. 
  • Add-ins: Add a crunchy texture to the creamy soaked oats by garnishing with fresh fruit, dried fruit and chopped nuts will. Check out this list of 75+ oatmeal toppings for so delicious inspirations.
  • Storage: Overnight oats will stay fresh for up to 5 days when stored in the refrigerator inside an airtight container.
