Zusatztipps für die Zubereitung

To get the best results, ensure you use a large soup pot to accommodate the volume of the fresh chard leaves before they wilt down. A high-quality chef's knife and a steady cutting board will make the preparation of the mirepoix (onions, carrots, and celery) efficient and uniform.

Varianten und Anpassungen

For a heartier version of this soup, consider adding one can (400 g) of drained white beans or a diced potato along with the carrots for extra body. To keep the recipe strictly vegan, simply omit the Parmesan cheese or swap it for a plant-based alternative.

Serviervorschläge

Recipe Questions & Answers

→ Can I use frozen Swiss chard instead of fresh?

Yes, frozen Swiss chard works well. Thaw and drain it first, then add it directly to the pot with the broth. You may need to reduce cooking time slightly since frozen chard is already blanched.

→ How do I store leftover soup?

Store in an airtight container in the refrigerator for up to 4 days. Reheat gently on the stovetop or in the microwave. The soup also freezes well for up to 3 months.

→ What can I substitute for Swiss chard?

Kale, spinach, or collard greens make excellent substitutes. Adjust cooking time accordingly—spinach wilts quickly while kale and collards may need a few extra minutes to become tender.

→ How can I make this soup more filling?

Add white beans, chickpeas, or diced potatoes for extra heartiness. You can also serve it over cooked quinoa or rice, or alongside crusty bread for a more substantial meal.

→ Can I make this soup in advance?

Absolutely. The flavors actually improve after a day in the refrigerator. Prepare it up to 2 days ahead, but add the lemon juice and parsley just before serving for the brightest flavor.

→ Is this soup spicy?

The red pepper flakes are optional and provide just a gentle warmth, not overwhelming heat. Feel free to omit them entirely for a milder soup, or increase the amount if you prefer more spice.
