  • ½ cup old-fashioned oats
  • ½ cup plain Greek-style yogurt (I used non-fat, but any variety will work)
  • ½ cup milk (I used unsweetened vanilla almond milk, but regular dairy milk, cashew milk or other milk of choice will work)
  • 1 tablespoon honey (or substitute with maple syrup)
  • ¼ teaspoon salt
  • ¼ teaspoon almond extract
  • ¼ teaspoon cinnamon
  • Pinch of nutmeg
  • ¼ cup sliced strawberries (plus additional for topping, if desired)
  • ¼ cup blueberries (plus additional for topping, if desired)
  • Optional: toasted sliced almonds for topping


  • In a small bowl or jar, stir together oats, yogurt, milk, honey, salt, almond extract, cinnamon and nutmeg.
  • Add berries to the oat mixture and stir to combine.
  • Cover and refrigerate for at least 2 hours so that the oats soften, thicken, and absorb the liquid.
  • Just before serving, top with additional berries and toasted almonds, if desired.


  • Overnight Oats Jar Size: I love using mason jars or the Weck jars that you see here for my oatmeal. The best size jar for this recipe is either the 16.9-ounce 1/2 liter tulip jar or the 1/2 liter mold jar (both shown in this post). These jars give you plenty of room to stir the oatmeal and add toppings!
  • Which oats are best for overnight oatmeal? I only use old fashioned (sometimes called “rolled”) oats for this recipe. These oats absorb the liquid in the jar, become soft and chewy, while still maintaining a bit of texture. I do not recommend substituting with quick oats or steel cut oats.
  • Keep the overnight oats ratio in mind, and feel free to multiply the ingredients using the same ratio to prepare more than one jar at a time. You want equal proportions of oats, yogurt and milk.
  • Use the base of this recipe to create your own flavor combination! Instead of topping with almonds, try adding peanut butter, almond butter, or toasted pecans or walnuts on top.
  • Mix up the fruit! Use just blueberries to make Blueberry Overnight Oatmeal, use raspberries or blackberries, or swap out the berries for other fruit instead. Try making Banana Overnight Oats or Peach Overnight Oats!
  • Prepare Chocolate Overnight Oats by adding unsweetened cocoa powder to the liquid mixture, or add a handful of chocolate chips. Garnished with a drizzle of peanut butter or some chopped peanuts on top, your breakfast will taste like a Reese’s Peanut Butter Cup!
  • I used plain, non fat Greek yogurt, but you can substitute with any yogurt that you prefer. Vanilla Greek yogurt would add a great touch of flavor and sweetness!
  • Feel free to use any type of milk in lieu of the almond milk. Regular milk, cashew milk, or any other favorite will work!
  • If you don’t have almond extract, you can substitute with vanilla extract.
  • Instead of honey, try sweetening the oats with maple syrup or agave syrup. Adjust the amount of sweetener to suit your preferences.
  • Prepare the oats in advance: This is a great “meal prep” option, since the oatmeal will stay fresh in an airtight container in your refrigerator for up to 5 days!
