Add oats and your all-natural sweetener of choice (pure maple syrup or honey).
Add in the remaining fruit and add-ins (except bananas, which you will add right before eating so they don’t turn brown and mushy).
Screw on the lid tightly and shake. Set in the refrigerator for at least 4 hours and up to 3-5 days.
You have two choices how to serve them:
Serve Cold: Shake the jar. Open and add in the bananas (if they are in your recipe). 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 in the sliced bananas (if they are in your recipe) and 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 3-4 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. Quick oats will result in a mushy, porridge-like consistency.
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.
Peanut butter/Peanuts Sub: Replace with almond butter, cashew butter, or sunbutter and almost any other finely chopped nuts you like. If you’re trying to avoid tree nuts, use shelled sunflower seeds or pumpkin seeds.
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.
