Prepare the silverbeet: Separate the stems from the leaves but cutting down each side of the stem with a sharp knife. Cut the stems into 1 cm / ⅓ inch slices, and slice the leaves into 3-4 cm (1 – 1 ½ inch) slices. Keep the leaves and stems separate.
Heat the olive oil in a large saucepan over a medium heat and cook the crushed garlic and silverbeet / chard stalks for 30 seconds.
Add the water, basil stalks, Parmesan rind, if using, nutmeg, salt and black pepper and bring to the boil.
Lower the heat slightly and simmer for 4 minutes.
Add the frozen peas, bring the soup back to the boil / simmer and then add the silverbeet leaves.
Simmer for 3-4 minutes until the peas are cooked and the leaves are tender.
Take off the heat and add the basil and grated Parmesan cheese.
Using a stick blender blend until smooth. Alternatively blend the soup in a blender.
Check for seasoning and serve.
Notes
INGREDIENTS INFO
Silverbeet – also known as chard or Swiss chard. I recommend against using rainbow chard in this particular recipe as the colour from it can make the soup become slightly brown rather than its appealing green colour.
Garlic – use fresh garlic rather than garlic powder, either fresh cloves, crushed, or 2 teaspoons of ready minced garlic.
Peas – frozen peas
Water – or use a salt-reduced stock. On testing I have found that store-bought stocks can, once combined with the parmesan cheese, make the soup taste very salty. A homemade vegetable stock would be a good alternative.
Parmesan – or use a vegetarian or vegan alternative.
Basil – fresh basil really makes the soup recipe sing! I don’t recommend substituting with dried basil in this particular recipe.
TIPS
Don’t overcook the soup – if you simmer the soup for too long, it can lose its vivid / bright green colour.
Adding the basil off the heat - helps it keep its bright, punchy flavour.
