  • Vegetables: 1 medium head cauliflower (cut into florets), 1 medium head broccoli (cut into florets), 1 medium onion (diced), 2 celery stalks (diced), 2 medium carrots (diced), 2 garlic cloves (minced).
  • Liquids: 4 cups vegetable broth, 1 cup milk or unsweetened plant-based milk.
  • Spices & Seasoning: 2 tbsp olive oil, 1 tsp dried thyme, 1/2 tsp dried oregano, salt and freshly ground black pepper to taste.
  • Croutons: 2 cups cubed crusty bread, 2 tbsp olive oil, 1/2 tsp garlic powder, pinch of salt.
  • Optional Toppings: 2 tbsp chopped fresh parsley, grated Parmesan or vegetarian hard cheese.

Instructions

1. Prepare the Croutons
Preheat your oven to 375°F (190°C). In a bowl, toss the bread cubes with olive oil, garlic powder, and a pinch of salt. Spread them in a single layer on a baking sheet and bake for 10–12 minutes until golden and crisp. Set aside.
2. Sauté the Aromatics
Heat 2 tbsp of olive oil in a large soup pot over medium heat. Add the diced onion, celery, and carrots. Sauté for about 5 minutes until the vegetables have softened. Stir in the minced garlic, thyme, and oregano, and cook for another minute until fragrant.
3. Simmer the Soup
Add the cauliflower and broccoli florets to the pot, stirring for 2–3 minutes. Pour in the vegetable broth and bring the mixture to a boil. Reduce the heat, cover, and simmer for 15–20 minutes until the vegetables are completely tender.
4. Blend and Season
Remove the pot from the heat. Use an immersion blender to process the soup until it reaches a smooth and creamy consistency. Stir in the milk and season generously with salt and pepper. Gently reheat the soup if necessary.
5. Garnish and Serve
Ladle the hot soup into bowls. Top with the homemade croutons, fresh parsley, and a sprinkle of cheese if desired. Serve immediately.

Zusatztipps für die Zubereitung

For the best results, use a large soup pot for even heat distribution and a baking sheet to ensure the croutons crisp up properly. If you do not have an immersion blender, you can use a stand blender, but remember to blend in small batches to avoid pressure buildup.

Recipe FAQs

Can I make this soup vegan?

Yes, simply use unsweetened plant-based milk such as almond, oat, or soy milk instead of dairy milk, and omit the Parmesan or use vegan cheese alternatives.

How do I store and reheat leftovers?

Store the soup in an airtight container in the refrigerator for up to 4 days. Reheat gently on the stovetop over medium heat, stirring occasionally. Add a splash of broth or milk if it thickens too much.

Can I freeze this soup?

Yes, this soup freezes well for up to 3 months. Cool completely before transferring to freezer-safe containers. Thaw overnight in the refrigerator and reheat on the stovetop. Note that croutons should be added fresh when serving.

What can I use instead of an immersion blender?

You can use a regular stand blender. Allow the soup to cool slightly, then blend in batches, filling the blender only halfway and holding the lid with a towel to prevent hot liquid from splashing.

How can I make the soup thicker or thinner?

For a thicker consistency, add less milk or broth, or stir in a tablespoon of flour or cornstarch mixed with water. For a thinner soup, simply add more vegetable broth or milk until you reach your desired consistency.

Can I add other vegetables to this soup?

Absolutely! Potatoes, zucchini, or peas work wonderfully. Add them along with the cauliflower and broccoli, adjusting cooking time as needed to ensure all vegetables are tender before blending.
