  1. In a 12- to 16-ounce Mason jar, pour in the milk.
  2. Add oats and your all-natural sweetener of choice (pure maple syrup or honey).
  3. Add in the remaining add-ins: vanilla Greek yogurt, raspberries, lemon zest, and sliced almonds for this version.
  4. Screw on the lid tightly and shake. Set in the refrigerator for at least 4 hours and up to 2-3 days for this version.
  5. When ready to eat, you can eat it cold or warm. Here’s how to serve it:
    • Serve Cold: Shake the jar. Stir in a little extra milk if it’s too thick and more sweetener if you’d like. Grab a spoon and eat your oats cold. This is the perfect solution for those mornings when you’re on the run!
    • Serve Warm: This is our preferred way to serve overnight oats. Shake the jar and then remove the lid. Warm the oats in the microwave for about 45 seconds. Stir. Add more milk or sweetener as needed. Warm up even more, if desired.

  • If using rolled oats, they ideally need to sit in the fridge for at least 4 hours but are even softer and better after 6-8 hours in the fridge.
  • It’s best to eat overnight oats within about 3-5 days, especially if you added in fresh or frozen fruit. After that, the texture and quality of the oatmeal deteriorate.
  • You can use steel-cut oats in place of the rolled oats, but they will require longer in the fridge to get soft and may need more liquid.
  • Feel free to add in some protein powder to your overnight oats to increase protein and calories. If using a sweetened protein powder, be sure to cut back on the sweetener in the overnight oats recipe. You may also need to add more liquid.
  • Gluten-Free Note: If you have a gluten allergy, be sure to buy certified gluten-free oats. While oats are a naturally gluten-free food, they are often processed in a factory where gluten is present.
  • Dairy-Free Version: Use vanilla almond milk and either omit the yogurt or use dairy-free yogurt.
