Ingredients You’ll Need
Just a handful of simple, fresh ingredients come together to make Creamy Rhubarb Overnight Oats absolutely irresistible. Each one plays a part in either texture, creaminess, or bright flavor—no fillers, just essentials!
- Rhubarb: That unmistakable tartness and gorgeous pink hue create the jammy fruit layer that makes these oats unforgettable.
- Honey or Maple Syrup: Both naturally sweeten the rhubarb as it cooks—pick whichever you love best for your oats.
- Water: Just a splash to help the rhubarb cook down perfectly without sticking.
- Old-fashioned Rolled Oats: The star of sturdy, comforting overnight oats; don’t swap for quick-cook or steel-cut here.
- Milk (dairy or non-dairy): This is what plumps up the oats so they’re creamy—use your favorite (even coconut or oat milk work great).
- Plain or Vanilla Greek Yogurt: Adds both tang and creaminess; vanilla works especially well if you love a little extra sweetness.
- Chia Seeds: They thicken the oats and add a subtle ‘pudding’ texture, not to mention fiber and omega-3s.
- Vanilla Extract: Just a splash pulls everything together and enhances both the oats and that fruity rhubarb flavor.
- Pinch of Salt: Trust me, it’s crucial for lifting all the flavors and making the sweet elements shine.
- Optional Toppings: Fresh strawberries, chopped nuts, an extra drizzle of honey, or more yogurt—these take your Creamy Rhubarb Overnight Oats from delicious to dazzling.
How to Make Creamy Rhubarb Overnight Oats
Step 1: Simmer the Rhubarb Mixture
Start by tossing your diced rhubarb into a small saucepan with your chosen sweetener and a bit of water. Cook this over medium heat, stirring every so often. In just 5 to 7 minutes, you’ll notice the rhubarb softening right into a gloriously jammy, rosy concoction. Let it cool completely—this is absolutely key so your yogurt doesn’t curdle when the two meet later.
Step 2: Mix Up the Oats Base
Now, in a medium bowl (or you can do all this straight in a large jar for easier cleanup!), stir together the oats, milk, Greek yogurt, chia seeds, vanilla extract, and a pinch of salt. Everything comes together quickly, and you’ll notice how instantly creamy it all looks—already a perfect start to your Creamy Rhubarb Overnight Oats experience.
Step 3: Fold in the Rhubarb
When your rhubarb mixture has cooled off, fold it gently into your oats base. You can swirl it all the way through or just leave bold streaks of pink—either way, it’s beautiful. Resist licking the spoon right then and there (or don’t, no judgement!).
Step 4: Refrigerate Overnight
Divide the mixture between two jars or bowls. Pop a lid or plastic wrap over the top and let those oats chill in the fridge for at least 6 hours, though overnight works best. The oats and chia seeds soak up all the creamy liquid so you’ll have that signature luscious, cake-batter-like texture in the morning.
Step 5: Top and Serve
In the morning, give your Creamy Rhubarb Overnight Oats a good stir. If you want it a bit looser, add a splash of milk. Top each serving with a few strawberry slices, a sprinkle of nuts, a dollop of yogurt, or an extra drizzle of honey if you’re in the mood for something a little extra special.
How to Serve Creamy Rhubarb Overnight Oats

Garnishes
Half the fun of these oats is going wild with garnishes! Try sliced strawberries to echo that classic “rhubarb & strawberry” combo, a handful of chopped pistachios or almonds for some crunch, a dollop of yogurt for extra luxury, or a drizzle of honey to boost the sweetness even further. A sprinkling of toasted coconut or even a dusting of cinnamon also works beautifully.
Side Dishes
Creamy Rhubarb Overnight Oats are hearty and filling on their own, but if you want to make breakfast feel even more abundant, serve with a mug of strong coffee or a pot of fruity tea. A side of scrambled eggs or a green smoothie also pairs well if you’re looking to create a full, balanced brunch spread.
Creative Ways to Present
Layer your Creamy Rhubarb Overnight Oats in individual glass jars for the prettiest presentation—and an easy grab-and-go option! You can even swirl in an extra layer of yogurt or roasted strawberries for extra color contrast. Garnish with edible flowers or a sprig of fresh mint to make breakfast feel like a true event, whether it’s for a spring brunch or just a treat-yourself Tuesday.
Make Ahead and Storage
Storing Leftovers
Store any leftover Creamy Rhubarb Overnight Oats tightly covered in the refrigerator. They’ll keep beautifully for up to three days, with the flavor actually improving as all the ingredients meld together. Just give them a good stir before eating!
Freezing
While overnight oats can be frozen for up to a month, the texture is best enjoyed fresh from the fridge. If you do freeze, portion the oats into airtight containers. Thaw overnight in the fridge and stir well—the rhubarb may get a little softer, but the taste is still delightful.
Reheating
These oats are meant to be enjoyed cold, but if you prefer something warm on a chilly morning, just pop them in the microwave in 30-second bursts, stirring in between, until gently heated through. Add a splash more milk to loosen them up if needed.
FAQs
Can I make Creamy Rhubarb Overnight Oats vegan?
Absolutely! Just use your favorite non-dairy milk and a plant-based yogurt. Maple syrup makes for the perfect sweetener if you’re keeping things plant-based.
What can I use instead of rhubarb if it’s out of season?
If you can’t find rhubarb, strawberries make an excellent substitute, or you can try a mix of raspberries for a similar tart-sweet flavor. Even frozen rhubarb works just as well as fresh!
How do I make these overnight oats even creamier?
For extra creaminess, opt for full-fat Greek yogurt and whole milk. You can also add an extra spoonful of yogurt just before serving for an ultra-luxurious texture.
Are Creamy Rhubarb Overnight Oats suitable for meal prep?
Yes! These oats were made for meal prep—they last several days in the fridge, so you can whip up a batch or two and enjoy fuss-free breakfasts all week.
Can I double or triple this recipe?
Definitely. The recipe scales up beautifully—just multiply all the ingredients as needed and store in a big container, or portion into individual jars for grab-and-go ease.
