Why I Love This Recipe
I made this soup one spring afternoon when I had fresh rhubarb in the fridge and no big plan for it. I wanted something light, cold, and easy. After it chilled, the color turned into this soft pink shade, and the flavor was so fresh. It felt special, but it was very simple to make.
What I love most:
- It tastes bright, tart, and lightly sweet.
- It looks beautiful in a bowl.
- It is easy to make ahead.
- The yogurt and cream make it smooth.
- It feels fancy without much work.
What You’ll Need
- 4 cups chopped fresh rhubarb
- 1 cup sliced strawberries
- 3 cups water
- 1/2 cup honey
- 1/4 cup sugar
- 1 tablespoon lemon juice
- 1 teaspoon lemon zest
- 1/4 teaspoon salt
- 1/2 teaspoon vanilla extract
- 1/2 cup plain Greek yogurt
- 1/4 cup heavy cream
- Extra heavy cream, for serving
- Fresh mint, for topping
Recipe and Instructions
Step 1: Add the fruit, water, and sweeteners
Add 4 cups chopped fresh rhubarb and 1 cup sliced strawberries to a medium saucepan. Pour in 3 cups water, 1/2 cup honey, and 1/4 cup sugar. Stir gently with a wooden spoon.
Step 3: Simmer the soup
Bring the mixture to a gentle simmer. Cook for 12 to 15 minutes, until the rhubarb is very soft and breaking apart.
Step 4: Add lemon, salt, and vanilla
Remove the saucepan from heat. Stir in 1 tablespoon lemon juice, 1 teaspoon lemon zest, 1/4 teaspoon salt, and 1/2 teaspoon vanilla extract.
Step 5: Blend until smooth
Carefully pour the warm mixture into a blender. Blend until the soup is smooth.
Step 6: Strain the soup
Pour the blended soup through a fine mesh strainer into a mixing bowl. This makes the soup silky.
Step 7: Add yogurt and cream
Whisk in 1/2 cup plain Greek yogurt and 1/4 cup heavy cream until smooth and creamy.
Step 8: Chill and serve
Cover the soup and chill for at least 2 hours. Serve cold in round bowls with extra heavy cream and fresh mint on top.
Pro Tips
- Taste before chilling. If your rhubarb is very tart, add 1 to 2 more tablespoons honey.
- Let the soup cool a little before blending so it is safer to handle.
- Strain the soup if you want it extra smooth.
- Chill for the full 2 hours. The flavor gets better when cold.
- Add cream and mint right before serving so it looks fresh.

Make Ahead Tips

Why This Recipe Works (Quick Science)
Rhubarb is naturally tart. Honey, sugar, and strawberries balance that tart flavor. Cooking softens the rhubarb so it blends smoothly. Yogurt and cream add fat, which makes the soup creamy and rich. Chilling helps the flavors blend together and taste better.
Common Mistakes
- Using too little sweetener: The soup can taste too sharp.
- Skipping the strainer: The soup may have stringy bits.
- Adding yogurt while the soup is too hot: It can look grainy.
- Not chilling long enough: The flavor may taste flat.
- Overloading toppings: Too many toppings can hide the fresh rhubarb flavor.
What to Serve With
- Shortbread cookies
- Pound cake
- Vanilla wafers
- Fresh berries
- Toasted brioche
- A light salad
- Tea or iced tea
