This bright rhubarb sauce transforms even the simplest breakfast or dessert with its tart-sweet punch and vibrant color. Whenever I spot fresh rhubarb at the market, I scoop it up just to make this for topping yogurt, ice cream, or even just buttered toast.
When I first made this sauce for my nieces on a sunny spring morning, we ended up spooning it over everything from pancakes to oatmeal. It instantly became our go-to weekend treat.
Ingredients
- Fresh rhubarb: Look for firm stalks with shiny skin and deep pink hues those without blemishes offer the best flavor and tender texture
- Granulated sugar: Adds sweetness to balance rhubarb’s natural tartness use pure white sugar for a clean taste and bright color
Step-by-Step Instructions
- Prepare the Rhubarb:
- Wash the rhubarb thoroughly and chop into half-inch pieces no need to peel unless the stalks are especially tough or stringy
- Combine in Pot:
- Use a pot one size bigger than you expect the mixture can bubble up as it cooks Add the chopped rhubarb and the sugar together
- Cook Gently:
- Place the pot over low heat Stir often so the sugar melts evenly and the rhubarb cooks slowly about five to eight minutes is enough The goal is for sugar to dissolve completely and for the rhubarb to break down into a chunky sauce
- Blend for Smoothness:
- Let the mixture cool enough to handle safely then use an immersion blender for easy pureeing right in the pot or transfer to a countertop blender for extra smooth results
- Chill and Store:
- Transfer sauce to a container and chill Refrigerate up to three days or pour into freezer-safe jars for longer storage

Rhubarb’s color is always my favorite part Every batch turns out slightly different sometimes more blush sometimes a bold pink Each spoon reminds me of spring mornings enjoying warm scones drizzled with sauce
