When is rhubarb in season?

Rhubarb is in season in the spring. In the Midwest specifically, you’ll see stalks ready for harvest in late April through early June.

If you live in the Midwest or Pacific Northwest, check your local farmer’s market in May for the best chance of finding it.

You may luck out to see rhubarb earlier in the year, which is greenhouse grown rhubarb. Either will work for this recipe.

Top tips

  • Don’t be tempted to add water to the rhubarb and sugar as they cook. The rhubarb will start to release its juices as it cooks, so water will just dilute the sauce.
  • On that note, stir the sauce often to ensure the sugar doesn’t burn on the bottom of the pan.
  • Have green rhubarb? You can make this sauce with a green variety, too! I used a mixture of green and red rhubarb (the green is the Victoria variety, and the red is Crimson Red).

Ingredients

rhubarb, sugar, and vanilla extract on a white table.

You just need 3 ingredients:

  • 2 cups of chopped rhubarb
  • Granulated sugar (you can increase or decrease the amount as you wish)
  • Vanilla extract—this is optional. I like the flavor both with and without it. Try both and see which you prefer!
