Step‑by‑Step Instructions for Rhubarb Overnight Oats
Step 1: Prepare Rhubarb Compote
Begin by chopping 2 cups of rhubarb into small pieces and placing them in a medium saucepan over medium heat. Add about 1 cup of water and your chosen sweetener, stirring occasionally. Simmer for 8-10 minutes, or until the mixture thickens and turns jammy. Once done, remove from heat and let it cool slightly while you prepare the oat mixture.
Step 2: Mix Oat Base
In a large jar or bowl, combine 1 cup of rolled oats, 1 cup of milk (dairy or plant-based), and 1/2 cup of Greek yogurt. If using, sprinkle in 2 tablespoons of chia seeds along with a pinch of salt and 1 teaspoon of vanilla extract. Mix well until everything is evenly incorporated, creating a creamy oat base that will pair beautifully with the rhubarb compote.
Step 3: Layer Rhubarb Compote
Once the rhubarb compote has cooled, gently layer it on top of the oat mixture. You can either swirl it in for a marbled effect or keep it as a layer for contrasting textures. Take a moment to admire the vibrant colors before covering the jar with a lid or plastic wrap, sealing in the flavors for the overnight process.
Step 4: Refrigerate
Place the covered jar in the refrigerator for at least 4 hours, but ideally overnight. This chilling time allows the oats to absorb the liquid, becoming soft and creamy while the flavors meld perfectly. When you open the fridge the next morning, you’ll be greeted by the delightful aroma of Rhubarb Overnight Oats.
Step 5: Serve
When you’re ready to enjoy your breakfast, give the mixture a good stir to combine the layers. If desired, add toppings such as chopped nuts, fresh fruits, or an extra drizzle of sweetener for added flavor and texture. Your Rhubarb Overnight Oats are now ready to be savored, providing a nutritious start to your day!

Make Ahead Options
These Rhubarb Overnight Oats are perfect for meal prep enthusiasts! You can prepare the oat mixture and the rhubarb compote up to 24 hours in advance. Simply follow the first three steps, and then refrigerate the assembled jars or bowls overnight to allow the oats to soften and the flavors to meld beautifully. To ensure your oats remain just as delicious, avoid adding any crunchy toppings, like nuts or granola, until just before serving (up to 3-4 days is ideal for the oats). When ready to enjoy, simply stir the mixture and add your favorite toppings for a quick, satisfying breakfast that will brighten your mornings!
