Ingredients

Scale

Soup Ingredients

  • 2 tablespoons olive oil
  • 2 tablespoons unsalted butter
  • 2 leeks (white and light green parts), cleaned and sliced
  • 1 small onion, chopped
  • 2 garlic cloves, minced
  • 1 medium celeriac (celery root), peeled and diced (about 1 ½ pounds)
  • 1 medium potato, peeled and diced
  • 1 teaspoon fresh thyme leaves (or ½ teaspoon dried)
  • 4 cups vegetable or chicken broth
  • 1 cup whole milk or cream
  • Salt and black pepper to taste

Gruyère Toasts

  • 1 small baguette, sliced
  • 1 cup shredded Gruyère cheese
  • 1 teaspoon fresh thyme leaves
  • Olive oil for brushing


Instructions

  1. Prepare the Aromatics: Heat the olive oil and butter in a large pot over medium heat. Add the leeks, onion, and garlic and cook for 5–7 minutes until soft but not browned, allowing the flavors to develop.
  2. Add Vegetables and Thyme: Stir in the diced celeriac, potato, and thyme to coat them evenly with the aromatics, enhancing their flavor.
  3. Simmer the Soup: Pour in the vegetable or chicken broth. Bring to a boil, then reduce the heat to low and simmer for 25–30 minutes or until the vegetables are tender when pierced with a fork.
  4. Puree the Soup: Remove the pot from heat and use an immersion blender to puree the soup until smooth. Alternatively, blend the soup in batches in a blender carefully.
  5. Finish and Season: Stir in the whole milk or cream for creaminess. Season with salt and black pepper to taste. Gently heat the soup until warmed through, avoiding boiling.
  6. Prepare Gruyère Toasts: Preheat the broiler. Arrange the baguette slices on a baking sheet, brush each slice with olive oil, and sprinkle with shredded Gruyère and fresh thyme leaves.
  7. Broil Toasts: Place under the broiler for 1–2 minutes or until the cheese melts and turns golden brown, watching carefully to prevent burning.
  8. Serve: Ladle the hot soup into bowls and serve with Gruyère toasts on the side or floated on top for a delicious contrast of textures.

Notes

  • For a dairy-free version, substitute olive oil for butter and use unsweetened plant-based milk instead of cream or whole milk.
  • The soup can be made ahead and refrigerated for up to 3 days; reheat gently before serving.
  • Use homemade or store-bought vegetable or chicken broth based on your preference to enhance flavor.
  • Fresh thyme adds brighter flavor but dried thyme works well as a substitute.
  • Adjust seasoning at the end since the cheese toasts add salty richness.
