Following the Dukan Diet doesn’t mean giving up dessert. If you’re craving something light, fluffy, and naturally sweet without added sugar, Sugar-Free Rhubarb Zephyr is a wonderful alternative to traditional marshmallows and mousse desserts.

Made with whipped egg whites, gelatin, sweetener, and tangy rhubarb, this elegant dessert delivers a soft, airy texture while remaining much lower in sugar than classic recipes.

It’s an excellent choice for anyone looking for a protein-rich dessert that fits into a healthy lifestyle.

What Is Zephyr?

Zephyr is a traditional Eastern European confection that resembles a cross between marshmallow and meringue. Classic recipes are usually made with fruit puree, sugar, and whipped egg whites.

For a Dukan-friendly version, sugar is replaced with an approved sweetener, and rhubarb is used instead of sweeter fruits.

The result is a light dessert with a refreshing, slightly tart flavor.

Is Rhubarb Allowed on the Dukan Diet?

Rhubarb is unique because, although it is often used in desserts, it is technically a vegetable rather than a fruit.

Attack Phase

❌ Not suitable, as vegetables are not included during the protein-only phase.

Cruise Phase

✅ Rhubarb may be included in moderation on Protein + Vegetables (PV) days because it is a low-carbohydrate vegetable.

Consolidation Phase

✅ A great dessert option, especially when prepared without added sugar.

Stabilization Phase

✅ Enjoy as part of a balanced eating plan.

Serves 6–8

• 500 g fresh rhubarb, chopped
• 2 large egg whites

• 100 ml water
• Granulated sweetener suitable for baking (to taste)

Instructions

Step 1

Cook the chopped rhubarb over low heat until soft.

Blend into a smooth puree and allow it to cool completely.

Step 2

Step 3

Beat the egg whites with a pinch of salt until stiff peaks form.
