    What to Serve with Overnight Oats

    Though they are a meal on their own, you could choose to pair them with other food and drinks.

    Variations and Substitutions

    • Use almond milk or another non-dairy milk instead of regular milk.
    • Add some chia seeds or flax seeds.
    • Use sea salt instead of kosher salt.
    • Add some dark chocolate chips or cacao nibs for a chocolate chip banana bread taste
      Substitute almond extract for the vanilla extract.
    • Add peanut butter or almond butter for peanut butter banana bread taste.
    • Use brown sugar or monk fruit sweetener instead of maple syrup for sweetness.
    • Add 1 tablespoon of protein powder of your choice. Chocolate, vanilla or peanut butter flavor would be yummy.
    • Not a fan of walnuts? Leave them out.

    How to Serve

    I recommend serving in a glass jar like a mason jar with a lid or a storage bowl with a lid. You want it to soak in the fridge in a container that has a lid and then you can just eat it out of its container.

    I love topping mine with fresh banana slices and extra maple syrup.

    Storage Instructions

    Store overnight oats in an airtight container in the refrigerator for up to 3 days. 

    Can I Freeze?

    Yes, you can freeze overnight oats for up to 3 months. Make sure to not add any of the toppings though. Thaw it first and then add your extra toppings.

    Do You Eat Overnight Oatmeal Cold?

    This Banana Bread Overnight Oats recipe is best served cold. If cold oatmeal isn’t your thing, you can serve it warm by heating it in the microwave. My preference is cold, but try it out and see which you like better.

    How Long Do Overnight Oats Need to Soak?

    Overnight oats should soak in the fridge for 6 hours, at minimum. It’s best to leave them in there overnight if you can. They’ll taste delicious in the morning.

    Can I Use Steel-Cut Oats?

    I wouldn’t recommend to use steel-cut oats in your overnight oats. They’ll be tough and chewy. They don’t soften like the old-fashioned oats do.

    Can I Use Quick Oats?

    I wouldn’t recommend quick oats (instant oats) either. They’ll get way too soggy in the milk mixture. Old-fashioned oats are the way to go!
