Add the rolled oats, low-fat cottage cheese, unsweetened almond milk, vanilla protein powder, chia seeds, vanilla extract, and ground cinnamon to a mason jar or airtight container large enough to hold all ingredients comfortably.
Stir the mixture thoroughly until all ingredients are evenly combined. Make sure the protein powder is fully incorporated and there are no dry pockets or clumps remaining. Scrape the sides and bottom of the container as needed to ensure even mixing.
Gently fold the diced strawberries into the oat mixture, distributing them evenly throughout the jar so every bite contains fresh strawberry flavor.
Secure the lid tightly on the container or mason jar to maintain freshness and prevent the oats from absorbing odors from the refrigerator.
Place the sealed container in the refrigerator and allow it to chill overnight or for at least 6 hours. During this time, the oats will soften, the chia seeds will absorb liquid and thicken the mixture, and the flavors will blend together beautifully.
Remove the overnight oats from the refrigerator before serving and stir thoroughly to redistribute the ingredients and create a creamy consistency.
If the oats are thicker than desired, add a small splash of unsweetened almond milk and stir until you reach your preferred texture.
Taste and adjust sweetness if needed by adding a few extra diced strawberries or a small drizzle of honey or maple syrup.
Top with additional fresh strawberries, chia seeds, chopped nuts, or any favorite toppings for extra texture and flavor.
Serve chilled and enjoy a creamy, satisfying high-protein breakfast that supports energy, fullness, and muscle recovery throughout the day.
