  • Total Time: 50 mins
  • Yield: 4 servings

Ingredients

Vegetables

  • 2 ½ lbs fresh asparagus (approximately 2 large bunches)
  • 2 onions, finely chopped
  • 3 cloves garlic, sliced
  • ½ lemon (juice only)

Stock & Dairy

  • 6 cups vegetable stock (1.4 litres)
  • ½ cup grated or shredded parmesan (100 grams)

Seasoning & Others

  • 2 tbsp butter
  • 1 sprig thyme
  • Seasoning to taste (salt and pepper)

Instructions

  1. Gather Ingredients: Collect all the necessary ingredients so you are ready to start the cooking process efficiently.
  2. Prepare Ingredients: Finely chop the onions, slice the garlic, shred the parmesan, extract the juice from half a lemon, remove asparagus tips from half of one bunch, and cut the remaining asparagus into roughly 2-inch pieces.
  3. Blanch Asparagus Tips: Bring a pan of water to boil and add the asparagus tips. Boil for 1 minute, then immediately strain and transfer them to a bowl of cold or iced water to stop the cooking process. Set aside these tips for garnish.
  4. Sweat Onions and Garlic: Place a large sauce pan over medium heat and melt the butter. Add the finely chopped onions and sliced garlic and gently sweat for about 8 minutes. Make sure the onions do not brown; they should soften and become translucent.
  5. Add Asparagus Pieces: Add the chopped asparagus stalks (not the tips) to the saucepan with the onions and garlic.
  6. Add Vegetable Stock and Thyme: Pour in the vegetable stock and add the sprig of thyme to the pan. Bring the mixture to a simmer.
  7. Simmer the Soup: Reduce the heat to low, cover the saucepan with a lid, and allow the soup to cook gently for 30 minutes until the asparagus is tender.
  8. Puree the Soup: Once cooked, remove the thyme sprig and use a hand blender or food processor to puree the soup until completely smooth.
  9. Add Lemon Juice and Parmesan: Stir in the fresh lemon juice and grated parmesan cheese into the hot soup until melted and well combined.
  10. Season and Serve: Taste and season with salt and pepper as needed. Serve the soup garnished with the refreshed asparagus tips, a sprinkling of parmesan, and a few thyme leaves for a fresh finish.

Notes

  • This soup is naturally low in fat as it uses no cream; the parmesan adds subtle richness.
  • Use fresh asparagus for the best flavor; frozen can be substituted but will alter the texture.
  • Be careful not to brown the onions when sweating; this keeps the soup’s flavor delicate and sweet.
  • The asparagus tips add a beautiful garnish and texture contrast—don’t skip blanching them.
  • Nutrition values are estimates calculated based on ingredient quantities and may vary.
