Ingredients
- 4 cups chopped fresh rhubarb – Look for vibrant pink stalks for the best flavor and color. If you can’t find fresh, frozen works too, just be sure to thaw it completely before using.
- 1 cup granulated sugar – You can adjust this to your liking – I sometimes use a bit less, depending on the sweetness of the rhubarb.
- 1 cup freshly squeezed lemon juice – Freshly squeezed is key here! Bottled juice just won’t give you the same vibrant flavor.
- 4 cups water – Filtered water is best to avoid any off-flavors.
- Lemon slices (optional) – A beautiful and tart garnish.
- Fresh mint sprigs (optional) – Adds a lovely herbal note – I love muddling a few sprigs before adding to the pitcher!
How to Make It
Let’s get started on this simple magic!
- Combine the rhubarb, sugar, and 2 cups of water in a medium saucepan. Bring this mixture to a rolling boil over medium-high heat. Once boiling, reduce the heat to low, and let it simmer gently for about 15 minutes, or until the rhubarb is completely soft and easily breaks down with a spoon. This is where the magic happens!
- Grab your fine-mesh strainer and a bowl. Carefully pour the rhubarb mixture through the strainer, pressing gently on the solids to extract every last drop of that delicious juice. Don’t worry about the solids; we’re discarding those. I usually use the back of a spoon to really get all the goodness out.
- Now, add the freshly squeezed lemon juice and the remaining 2 cups of water to the strained rhubarb mixture. Give it a good stir. Taste it – you can adjust the sweetness by adding more sugar or the tartness with a little extra lemon juice, depending on your preference.
- Pop the pitcher into the refrigerator for at least an hour to let those flavors really meld. The longer it chills, the better it tastes! Serve over ice and garnish with fresh lemon slices and/or mint sprigs. For a fun twist, try using chilled sparkling water instead of the final 2 cups of regular water for a bubbly rhubarb lemonade!

Substitutions & Additions
Feeling creative? Here are a few ideas to play around with:
- Sugar Substitute: Try using agave nectar, maple syrup, or a sugar alternative like stevia for a healthier option. Just remember to adjust the amount to your taste.
- Berry Boost: Add a cup of your favorite berries (strawberries, raspberries, blueberries) to the saucepan with the rhubarb for an extra layer of fruity flavor.
- Spicy Kick: A pinch of ginger or a few slices of jalapeño added during simmering will give your lemonade a surprising zing!
Tips for Success
- Don’t overcook the rhubarb: Overcooked rhubarb can become mushy and bitter. Aim for tender but not falling-apart consistency.
- Make it ahead: This lemonade tastes even better the next day! Make it a day or two in advance for the best flavor development.
- Strain thoroughly: Ensure you strain the mixture well to remove all the fibrous rhubarb pieces. This gives you a smoother, more elegant drink.
How to Store It
Store your leftover lemonade in an airtight container in the refrigerator for up to 3 days. It will keep its freshness and delicious flavor.
FAQs
- Q: Can I freeze this lemonade? A: While you can freeze it, the texture might change slightly upon thawing. It’s best enjoyed fresh or within a few days.

- Q: Can I use frozen rhubarb? A: Yes, just be sure to thaw it completely before using. You may need to adjust the simmering time slightly.
