Rhubarb Overnight Oats makes a fantastic make ahead breakfast to help with busy mornings. Summer mornings aren't meant to be rushed and hectic like during the school year, but sometimes we can't help it.
That's when a delicious make ahead shortcut like overnight oats comes in handy. You can prep both the oats and the rhubarb sauce the night before.

💭 Frequently Asked Questions
Here are some questions (and answers!) readers often ask about making overnight oats and rhubarb.
Oatmeal and Overnight Oats are a great healthy breakfast because they contain whole grains and a lot of soluble fiber which helps fill you up.
Similar to strawberries, rhubarb is in season from about April through July.
Rhubarb can be a bit tart, so adding some sweetness from honey, agave nectar or maple syrup is delicious. Strawberries and rhubarb are a classic combination, but it is also good with blueberries.
Similar to celery, rhubarb stalks can have tough stringy pieces. If your rhubarb is tender, you don't have to worry about that. However, any tough strings should be removed.
You can use any type of container with a lid to make overnight oats.
🧂 Ingredients
Makes 2 servings
- 1 cup quick cooking oats

For the Sauce:
The Rhubarb Sauce is so good over this oatmeal, but it's also delicious with ice cream, waffles, yogurt and more!
- 3 cups rhubarb stalks
- juice from ½ lemon
- ¾ cup water
- 1-½ cups sugar
- In a sauce pot, bring the water, rhubarb, lemon juice and sugar to a boil.
- Lower heat, allow to simmer (uncovered) for about 40 minutes to allow the rhubarb to breakdown.

🍴 Serving Suggestions
Overnight Oats with Homemade Rhubarb Sauce also make a really tasty snack or even dessert. Serve it cold or warm it up - either way it's tasty!
📖 Variations
There are so many scrumptious possibilities with overnight oats. Add sliced strawberries to the top of your oats, or mix in a pinch of cinnamon.
I like to have a few plain overnight oats on hand to curb cravings. Drizzle on a little honey and some toasted almonds and raspberries for a decadent dessert that's actually good for you! For the kids, make smaller portions with their favorite fruits on top.
⏲️ Storage
Overnight oats must be stored in the refrigerator. These are best eaten in the first one or two days, although they will last for about five days.
