Ingredients
Scale
Soup
- 3 Tablespoons butter
- 1 small onion, chopped
- 3 Tablespoons flour
- 1 teaspoon Italian seasoning
- 2 bunches asparagus, ends trimmed and discarded, cut into 1 inch pieces
- 4 cups vegetable stock
- 1 teaspoon kosher salt
- 8 grinds fresh black pepper
- 1 cup heavy cream
Garnish
- Parmesan cheese shavings
- Homemade Garlic Croutons (French bread or baguette cubes, olive oil, garlic powder, salt, pepper)
Instructions
- Sauté the onion: In a large soup pot or Dutch oven over medium heat, melt the butter and sauté the chopped onion until softened and just starting to brown, about 5 to 7 minutes.
- Make the roux: Add the flour and Italian seasoning to the butter and onions, whisking constantly for about one minute to form a roux, which will thicken the soup.
- Cook asparagus: Add the asparagus pieces and vegetable stock to the pot. Season with kosher salt and fresh black pepper. Bring the mixture to a boil, then cover and reduce heat to medium-low. Simmer for about 15 minutes, stirring occasionally.
- Add cream and blend: Stir in the heavy cream. Transfer the soup in batches to a blender or use an immersion blender directly in the pot. Blend until the soup is very smooth, taking care to vent the blender lid to allow steam to escape safely.
- Simmer again and adjust seasoning: Return the pureed soup to the pot and simmer for a few more minutes. Taste and add extra salt if needed.
- Make garlic croutons: Preheat oven to 400°F (200°C). Cut French bread or baguette into cubes and toss with olive oil, garlic powder, salt, and pepper. Spread on a sheet pan and bake for 5 to 10 minutes, shaking or flipping halfway through until crisp and golden.
- Serve: Ladle the soup into bowls. Garnish with Parmesan cheese shavings and the homemade garlic croutons. Optionally serve with additional crusty bread or sandwiches. Enjoy your spring asparagus soup!
