The secret to this soup's rich flavor is the combination of sautéed aromatics and a single potato, which provides a natural creaminess without needing heavy cream. By simmering the vegetables in a savory vegetable stock and blending them to perfection, you create a velvety base that highlights the subtle sweetness of the cauliflower and the earthiness of the broccoli.

Ingredients

• Vegetables: 1 medium head cauliflower (cut into florets), 1 medium head broccoli (cut into florets), 1 medium onion (diced), 2 medium carrots (diced), 2 celery stalks (diced), 3 cloves garlic (minced), 1 medium potato (peeled and diced).
• Liquids: 1.2 liters (5 cups) vegetable stock, 200 ml (3/4 cup) whole milk or plant-based milk, 2 tbsp olive oil.
• Seasonings: 1 tsp dried thyme, 1/2 tsp ground black pepper, 1 tsp salt, pinch of nutmeg (optional).
• Croutons: 2 cups day-old bread (cut into cubes), 2 tbsp olive oil, 1/2 tsp garlic powder, salt and pepper to taste.

Instructions

Step 1: Prep

Preheat the oven to 180°C (350°F) for the croutons.

Step 2: Sauté Aromatics

In a large pot, heat 2 tbsp olive oil over medium heat. Add onion, carrot, and celery. Sauté for 5 minutes until softened.

Step 3: Add Vegetables

Stir in garlic and cook for 1 minute. Add potato, cauliflower, and broccoli. Sauté for another 3 minutes.

Step 4: Simmer

Pour in the vegetable stock and add thyme, salt, pepper, and nutmeg. Bring to a boil, then reduce heat and simmer for 20 minutes until vegetables are tender.

Step 5: Bake Croutons

Meanwhile, toss bread cubes with olive oil, garlic powder, salt, and pepper. Spread on a baking sheet and bake for 10–12 minutes until golden and crisp.

Step 6: Blend

Remove the pot from heat. Use an immersion blender to blend the soup until smooth, or blend in batches in a countertop blender.

Step 7: Finish

Stir in the milk and gently reheat the soup. Adjust seasoning to taste.

Step 8: Serve

Ladle the soup into bowls and top generously with the homemade croutons.

Zusatztipps für die Zubereitung

For extra creaminess, you can stir in 2 tablespoons of cream cheese or a splash of heavy cream at the very end. If you are using a countertop blender, be careful when blending hot liquids—always leave a gap for steam to escape and blend in small batches.

Varianten und Anpassungen

Make it vegan by simply using a plant-based milk such as almond or soy milk. For those who enjoy a bit of heat, add a pinch of chili flakes or smoked paprika during the seasoning stage. For a gluten-free version, use gluten-free bread for the croutons and ensure your vegetable stock is certified gluten-free.

Recipe FAQs

→ Can I make this soup ahead of time?

Yes, prepare the soup up to 3 days in advance and store in the refrigerator. Make croutons fresh before serving for the best texture, or store separately in an airtight container.

→ How can I make this soup creamier?

Add 2 tablespoons of cream cheese while blending, or stir in a splash of heavy cream at the end. For dairy-free creaminess, use full-fat coconut milk or cashew cream.

→ Can I freeze cauliflower and broccoli soup?

Yes, freeze the soup without milk for up to 3 months. Thaw overnight in the refrigerator, reheat gently, then stir in fresh milk before serving. Add croutons just before eating.

→ What can I use instead of an immersion blender?

Use a countertop blender in batches, being careful with hot liquid. Leave the lid slightly open and cover with a towel to allow steam to escape. A food processor also works well.

→ How do I make this soup vegan?

Replace whole milk with unsweetened almond, oat, or soy milk. Use plant-based butter for sautéing if desired, and ensure your vegetable stock is vegan-certified.

→ What other vegetables can I add to this soup?

Try adding zucchini, spinach, kale, or peas for extra nutrition. Leeks make an excellent substitute for onions, and parsnips add natural sweetness alongside the potato.
