This easy rhubarb jam recipe combines fresh rhubarb, sugar, and lemon juice into a bright, sweet-tart homemade jam with soft fruit texture and fresh spring flavor. Perfect for toast, biscuits, yogurt, pancakes, and desserts.
Wash and trim the rhubarb stalks, discarding the leaves, then chop the stalks into 1/2-inch pieces.
Add the chopped rhubarb, sugar, lemon juice, lemon zest, and salt to a heavy saucepan.
Let the mixture rest for 15 minutes so the sugar can draw moisture from the rhubarb.
Place the saucepan over medium heat and stir until the sugar fully dissolves.
Simmer the jam for 18 to 25 minutes, stirring often, until thickened and glossy.
Lightly mash the rhubarb with a potato masher if you prefer a smoother jam texture.
Remove the saucepan from the heat and stir in the vanilla extract.
Spoon the jam into clean jars and allow it to cool before refrigerating or freezing.
Notes
You do not need pectin for this recipe because rhubarb naturally thickens as it cooks with sugar and lemon juice. For a smoother texture, lightly mash the jam while simmering. Store refrigerated jam for up to 3 weeks or freeze for longer storage.
