Step‑by‑Step Instructions for Rhubarb Overnight Oats
Step 1: Prepare the Rhubarb
In a small saucepan, add the chopped rhubarb and a splash of water over medium heat. Simmer for about 5–7 minutes, stirring occasionally, until the rhubarb becomes soft and slightly mushy. Once softened, remove from heat and let it cool to room temperature, allowing the vibrant flavors to deepen.
Step 2: Combine the Oats Base
In a mason jar or bowl, combine the rolled oats, milk of your choice, and plain yogurt. Add honey, vanilla extract, cinnamon, and a pinch of salt to enhance the flavors. Stir gently until all the ingredients are well incorporated and the mixture is creamy and thick. Ensure there are no dry oats remaining for a perfect texture.
Step 3: Mix in the Rhubarb
Once the cooked rhubarb has cooled, carefully fold it into the oat mixture. Use a spatula to evenly distribute the rhubarb throughout, ensuring each spoonful of your Rhubarb Overnight Oats carries the tartness of the fruit. This combination creates a delightful texture and a burst of flavor in every bite.
Step 4: Refrigerate Overnight
Seal the jar tightly with a lid or cover the bowl with plastic wrap. Place the jar in the refrigerator and let it chill overnight, or for at least 4 hours. This allows the oats to soak up the milk and yogurt, resulting in a creamy, satisfying consistency that’s perfect for breakfast.
Step 5: Serve and Enjoy
In the morning, give your Rhubarb Overnight Oats a good stir to mix everything together. Check the consistency; if it’s too thick, add a splash of milk. Serve your oats in a bowl or enjoy straight from the jar with your favorite toppings like chia seeds, nuts, or extra fresh fruit to elevate the experience.

Make Ahead Options
These Rhubarb Overnight Oats are a fantastic choice for meal prep, allowing you to enjoy a nutritious breakfast with minimal morning effort! You can prepare the oats mixture (including rolled oats, milk, yogurt, honey, vanilla, cinnamon, and salt) up to 3 days in advance and store it in the refrigerator in a sealed container. Just cook the rhubarb and let it cool before combining it with the oats; this ensures the flavors meld beautifully. In the morning, simply give the mixture a good stir, adjusting the consistency with a splash of milk if needed, and top with your favorite additions like nuts or fruits for a delightful start to your day!
