• Liquids: 4 cups (1 liter) vegetable broth, 1 cup (240 ml) milk or unsweetened plant-based milk.

Instructions

Step 1

Preheat oven to 375°F (190°C) for the croutons.

Step 2

Toss bread cubes with olive oil, garlic powder, and salt. Spread on a baking sheet and bake for 10–12 minutes or until golden and crisp. Set aside.

Zusatztipps für die Zubereitung

To ensure a smooth result, ensure you have a large soup pot and a reliable immersion blender or stand blender ready. If using a stand blender, be careful to blend in small batches to manage the steam. Slicing the vegetables into uniform pieces will help them cook evenly within the 20-minute simmering window.

Varianten und Anpassungen

For a vegan version, simply swap the dairy for plant-based milk and omit the cheese. If you require a gluten-free meal, use gluten-free bread for the croutons. For an extra layer of warmth, consider adding a pinch of nutmeg, or replace the bread with roasted seeds for a different crunch.

Serviervorschläge

Serve this creamy soup hot, garnished with fresh parsley and a sprinkle of Parmesan. For added indulgence, stir in a splash of cream or a dollop of sour cream just before serving. This dish pairs beautifully with a crisp Sauvignon Blanc to balance the earthy vegetable flavors.

Recipe FAQs

→ Can I freeze this soup?

Yes, freeze without the milk and croutons. Cool completely, store in airtight containers for up to 3 months. Thaw overnight, reheat, then stir in milk before serving.

→ How do I make it thicker?

Simmer longer to reduce liquid, add a peeled potato during cooking, or stir in puréed white beans. A splash of cream also creates rich body.

→ What herbs work best?

Fresh thyme, rosemary, or sage enhance earthiness. Dried oregano and basil work well too. Add fresh herbs at the end to preserve brightness.

→ Can I use frozen vegetables?

Absolutely. Use equal amounts frozen cauliflower and broccoli. No need to thaw—add directly to pot. Simmering time may increase slightly.

→ How do I prevent curdling?

Remove pot from heat before adding milk. Warm milk slightly first and stir gently. Avoid boiling after dairy is incorporated.

→ What bread makes the best croutons?

Day-old sourdough, baguette, or rustic country bread yield superior crunch. Stale bread absorbs oil better and toasts more evenly.
