  • 1/2 cup liquid
  • 1 teaspoon flax seed
  • 1 teaspoon chia seeds
  • 1/2 cup oats quick cooking or old fashioned
  • 1 scoop protein powder optional
  • 1 tablespoon melted coconut oil optional


  • Place liquid, flax seed, chia seeds in mason jar. Add in protein powder and or coconut oil if using. Secure lid and shake each jar until ingredients well combined.
  • Open each jar and add in desired toppings/flavor options.
  • Add oats and secure lid once again and shake until ingredients are well combined. 
  • Refrigerate overnight.
  • Serve in morning cold or can warm up slightly.


  • Nutritional values are based on base oatmeal without protein powder and coconut oil.
  • Add in any desired toppings (see post for suggestions)
  • Meal prep with overnight oats by making several mason jars worth of overnight oatmeal for the week. Overnight Oats will keep in fridge for up to 5 days. 
  • Use any variety of milk you like in this oatmeal. I use unsweetened vanilla almond milk, but regular milk, coconut milk, soy milk all work great.
  • 8 ounce or pint sized jars work for these overnight oats. You can double or triple the recipe and use quart sized jars. Just dish out oatmeal in morning into individual bowls.
  • Be sure to use certified gluten-free oats if you need your oatmeal to be gluten free.
  • Both quick cook and old fashioned oats work in this recipe.
  • If you prefer your oatmeal warm, just take the lid off and microwave for 1-2 minutes and then serve.
  • I love serving oatmeal in mason jars with handles so that my kids can hold them easily in the car if we are really running late in the morning and they have to eat their Overnight Mason Jar Oatmeal on the Go--not that that ever happens!!
