Overnight Oats Base Recipe

two jars of overnight oats side by side with black spoons in them and blackberries on top.

What do you have on hand? Great! Make overnight oats out of any ingredients with this basic, flexible formula for overnight oats.


  • 3/4 cup liquid ingredients (any combination of milk of choice, juice, yogurt, kefir, fruit/veggie puree, etc)
  • 1/2 cup oats (old fashioned rolled oatmeal, quick oats, instant oats, or quick steel cut oats)
  • extras any combination of flavors, toppings and nutrition boosters (see post above for suggested amounts)


  1. Mix liquid ingredients in a jar or other container with a lid, including yogurt/milk/juice/etc for the base, any liquid sweeteners, extracts, or nut butters, and any powders.
  2. Add in dry ingredients: oats (of course!), seeds, nuts, fruit, and spices.
  3. Stir well or close the lid and shake it all up!
  4. Let the mixture sit in the refrigerator overnight or at least 5-6 hours.
  5. Enjoy hot or cold in the morning with any additional toppings you'd like!


  • You can easily double or triple this recipe for multiple servings to share or to eat throughout the week. Overnight oats will keep for 3-5 days in the refrigerator.
  • To heat overnight oats, pour them into a microwave-safe bowl (if they aren't already in a glass jar) and heat, uncovered, for 1-2 minutes, stirring halfway through.
  • I usually mix toppings into the jar when I'm making overnight oats, but you can also wait until you're ready to eat to add the toppings.
  • Use an almost-empty nut butter jar or large yogurt container to get the last bits and to repurpose the container (and save you another dirty dish!).
