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.

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.

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.
