    Ingredient Notes 

    Rolled Oats: Rolled oats, also known as old-fashioned oats, are ideal for this overnight oat recipe. They absorb the water well, giving a creamy texture by the next morning. Avoid using quick oats or steel-cut oats as they may not soften as well. If you need a gluten-free version, make sure to get certified gluten-free oats.

    Peanut Butter: Creamy peanut butter adds a delicious, nutty taste and healthy fats to your oats. However, feel free to replace it with other nut or seed butters like almond butter, cashew butter, or sunflower seed butter.

    Chia Seeds: Chia seeds are a great addition to overnight oats, as they absorb water and turn into a gel-like consistency, similar to chia pudding, adding thickness to the oats. They also provide a good amount of dietary fiber and protein.

    Banana: Bananas not only add natural sweetness to your oats but also create a creamier texture. Make sure to choose ripe but not overripe bananas to avoid overpowering the other flavors.

    Recipe Tips 

    • This recipe is perfect for meal prep. Make a larger batch and divide it into 16-ounce jar or other individual jars. It’s a great make-ahead breakfast idea!
    • For the best texture, thoroughly mix your oats with the other ingredients. This ensures all the oats are coated and will soak properly.
    • For an extra protein kick, consider adding a scoop of your favorite protein powder. You can also add a splash of vanilla extract or a pinch of cocoa powder for added flavor.

    Storage & Reheating 

    Store your prepared overnight oats in an airtight container in the refrigerator. They’ll stay fresh for up to 5 days, perfect for meal prep for the week. As it’s a cold oatmeal recipe, there’s no need for reheating. Simply take your oats out of the fridge the next day and enjoy.

    Additions & Substitutions 

    If you want a sweeter oatmeal, consider adding a bit of brown sugar or maple syrup. For a different flavor, replace the water with a plant-based milk like almond milk, soy milk, or cashew milk. You can even use orange juice for a fruity twist.

    For a vegan overnight oats version, swap the peanut butter for almond butter or cashew butter, and add some vegan yogurt for extra creaminess. You can also mix in some healthy ingredients like hemp seeds or flax seeds.

    Recipe FAQs

    What should I serve with this milk-free overnight oats recipe?

    This overnight oats recipe is a complete meal in itself, packed with whole grain oats, healthy fats, and protein. But if you’d like, you can serve it with some fresh berries or other fresh fruit for extra vitamins and fiber. A dollop of Greek yogurt, vegan or regular, will add creaminess and a boost of protein. This recipe is the perfect way to start your day!
