# How to Make It:

01 - Preheat oven to 350°F for the croutons.
02 - In a large pot, heat 2 tablespoons olive oil over medium heat. Add onion, carrot, and celery. Sauté for 5 minutes until softened.
03 - Stir in garlic and cook for 1 minute. Add potato, cauliflower, and broccoli. Sauté for another 3 minutes.
04 - Pour in the vegetable stock. Add thyme, salt, pepper, and nutmeg. Bring to a boil, then reduce heat and simmer for 20 minutes until vegetables are tender.
05 - Meanwhile, toss bread cubes with olive oil, garlic powder, salt, and pepper. Spread on a baking sheet and bake for 10 to 12 minutes, turning once, until golden and crisp. Set aside.
06 - When vegetables are soft, remove the pot from heat. Use an immersion blender to blend the soup until smooth, or blend in batches in a countertop blender.
07 - Stir in the milk and gently reheat the soup. Adjust seasoning to taste.
08 - Ladle the soup into bowls and top generously with homemade croutons.

# Expert Tips:

01 -
  • It turns humble vegetables into something rich and velvety without needing heavy cream.
  • The homemade croutons add a satisfying crunch that store-bought versions just cant match.
  • You can blend it smooth or leave it chunky depending on your mood.
  • It reheats beautifully, so leftovers taste just as good the next day.
02 -
  • Dont skip the potato, its what makes the soup thick and creamy without any dairy or flour.
  • Blend the soup while its still hot for the smoothest texture, cold soup never blends as well.
  • If youre using a countertop blender, never fill it more than halfway with hot liquid or it can explode out the top.
  • The croutons will get soggy if you add them too early, so always top each bowl right before serving.
03 -
  • Use day-old bread for croutons, fresh bread just turns chewy instead of crispy.
  • Taste the soup after blending and before adding milk, sometimes it needs more salt or pepper than you think.
  • If you want a chunkier texture, blend only half the soup and stir it back into the pot with the unblended portion.
  • Make a double batch and freeze half, it thaws beautifully and tastes just as good weeks later.
