How to Make Lemon Poppy Seed Overnight Oats

• Add the rolled oats into a medium mixing bowl and make sure they are evenly spread before adding the liquid ingredients.
• Pour the milk into the bowl and stir gently so all the oats begin absorbing the liquid evenly.
• Add the plain Greek yogurt and mix thoroughly until the mixture becomes smooth and creamy without any lumps.
• Stir in the maple syrup and vanilla extract to create a lightly sweet and balanced flavor.
• Zest a fresh lemon carefully using a fine grater and add the zest directly into the oat mixture for bright citrus aroma.
• Squeeze fresh lemon juice into the bowl and stir immediately to distribute the tangy flavor evenly throughout the oats.
• Sprinkle in the poppy seeds and chia seeds, mixing thoroughly so they are evenly incorporated into the creamy oat base.
• Add a small pinch of sea salt to enhance the sweetness and lemon flavor.
• Stir the mixture very well for at least one minute to ensure all ingredients are fully combined and evenly hydrated.
• Divide the oat mixture into individual mason jars or airtight containers for easy grab-and-go breakfasts.
• Cover the jars tightly with lids and refrigerate overnight or for at least 6 hours until the oats become thick and creamy.
• Remove the jars from the refrigerator the next morning and stir the oats gently before serving.
