Nutritional benefits

Radish tops are rich in fibre, vitamin C and antioxidants, and far too often thrown away: cooking them cuts food waste and is nutritious. The potato gives creaminess without cream. A light, budget-friendly, eco-friendly green soup, ideal for weight loss. Naturally vegan and gluten-free.

Variations and substitutions

• With carrot or beetroot tops.
• Creamier: add soft cheese or coconut milk.
• More protein: red lentils.
• With herbs: chervil, parsley.

Storage and making ahead

Keeps for 3 days. Blend straight after cooking to keep the green colour.

💡 Good to know

Wash the tops very well (they are often gritty) and cook them briefly: they keep their colour and nutrients.
