Overnight oats are one of our favorite quick, easy, and healthy breakfasts, especially for busy mornings when the time to prepare a nutritious breakfast is lacking.

As the name implies, this breakfast takes "overnight" to come together. The night before, combine certified gluten-free old-fashioned rolled oats with your favorite dairy or non-dairy product, i.e. milk, almond milk, cashew milk, soy milk, Greek yogurt, etc., as well as a hint of natural sweetener such as maple syrup, agave nectar, or honey.

When the oats chill overnight, they soften as they absorb the milk/yogurt and sweetener. The mixture will thicken into a hearty and healthy start to the day by the time you wake up in the morning. 

Ingredients

  • 1/2 cup gluten-free rolled oats

  • 1/2 cup milk, plus more to taste

  • 1 tablespoon honey

  • 1/3 cup berries or fruit, or to taste

  • 1 to 2 tablespoons chopped nuts

  • 1 to 2 tablespoons flax seeds

Variations

Recipe Variations

The recipe is a simple blueprint for preparing gluten-free overnight oats, a basic outline of simple building blocks. You add the flair and customize it to make it your own:

  • Use non-dairy milk or Greek yogurt instead of milk. Using Greek yogurt will result in a very thick breakfast; if you go the yogurt route, always add a few more tablespoons of Greek yogurt in the morning to make the mixture thinner and creamier.
  • Sweeten the oats with agave nectar or another natural sweetener instead of honey.
  • Switch from flax seeds to hemp seeds or chia seeds.
  • Add sliced strawberries, bananas, raspberries, blueberries—or all four!
  • Mix in a tablespoon of flaxseed, chia seeds, or hemp seeds. 
  • For a sweeter kick, add additional honey, maple syrup, or agave nectar to taste.
  • For more crunch, add your choice of chopped nuts, such as almonds, walnuts, or pecans.

Gluten Free

Note about gluten-free oats: Oats are often grown in the same fields as non-gluten-free grains, such as wheat, barley, and rye, and harvested, stored, and processed with the same equipment. Because of this cross-contamination issue, consuming "regular" oats when following a gluten-free diet can be risky. When shopping for oats and oatmeal, be sure to check the label to ensure they are certified gluten-free.

It is important to note that a small percentage of those following a gluten-free diet for health reasons react to oats (even if certified gluten-free) because of a protein in oats called avenin. It is recommended to consult with your doctor about introducing oats into your diet if you have gluten-related health issues.  

Reminder: Always make sure your work surfaces, utensils, pans, and tools are free of gluten. Always read product labels to confirm the product is gluten-free. Manufacturers can change product formulations without notice. When in doubt, do not buy or use a product before contacting the manufacturer for verification that the product is free of gluten.
