→ Croutons

15 - 2 cups day-old bread, cut into cubes
16 - 2 tablespoons olive oil
17 - 1/2 teaspoon garlic powder
18 - Salt and pepper, to taste

# Directions:

01 - Preheat the oven to 350°F for toasting the croutons.
02 - Heat 2 tablespoons olive oil in a large pot over medium heat. Add diced onion, carrot, and celery. Cook for 5 minutes until softened.
03 - Stir in minced garlic and cook for 1 minute. Add diced potato, cauliflower florets, and broccoli florets. Sauté for an additional 3 minutes.
04 - Pour in vegetable stock and add dried thyme, salt, black pepper, and nutmeg. Bring to a boil, then reduce heat and simmer for 20 minutes until all vegetables are tender.
05 - While soup simmers, toss bread cubes with olive oil, garlic powder, salt, and pepper. Spread on a baking sheet and bake for 10 to 12 minutes, stirring once halfway through, until golden and crispy. Set aside.
06 - Remove pot from heat. Using an immersion blender, blend the soup until smooth. Alternatively, carefully transfer the soup in batches to a countertop blender and blend until smooth.
07 - Stir in the milk and gently reheat the soup over low heat without boiling. Taste and adjust seasoning as needed.
08 - Ladle the soup into bowls and top generously with homemade croutons.

# Expert Suggestions:

01 -
  • It turns everyday vegetables into something silky and satisfying without any fancy techniques.
  • The homemade croutons add just enough crunch to make each spoonful feel complete.
  • 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 -
  • Don't skip the potato, it's what makes the soup thick and creamy without needing flour or cream.
  • Blend the soup while it's still hot for the smoothest texture, cold soup doesn't blend as well.
  • Taste before adding the milk, sometimes the vegetables are sweet enough and you need more salt than you think.
03 -
  • Use the broccoli and cauliflower stems, they have just as much flavor as the florets and add body to the soup.
  • If your blender struggles with hot liquid, let the soup cool for ten minutes before blending to avoid a kitchen disaster.
  • Make the croutons while the soup simmers so everything finishes at the same time and your kitchen smells amazing.
