  • 2 tablespoons olive oil
  • 1 large white onion peeled and diced
  • 1 ½ pounds (680g) asparagus cut into 1 inch pieces, woody-ends discarded
  • 2 garlic cloves minced
  • 3 cups (709ml) chicken broth
  • salt and pepper to taste
  • squeeze of lemon juice
  • shredded cheese optional


  • Set the Instant Pot to the sauté setting. Add the olive oil and the onion and cook until translucent.
  • Add the asparagus and cook for 2-3 minutes until soft. Then add garlic and cook for about another 30 seconds, until fragrant. Stir in chicken stock, salt, and pepper.
  • Place on the lid and turn the valve to the sealing position. Set to manual pressure / high pressure for 5 minutes.
  • When done, allow a natural pressure release for 7 minutes and then perform a quick pressure release (QPR) to manually release any remaining steam.
  • Open the Instant Pot and allow the soup to cool for a few minutes before using an immersion blender, or transfer to a high-powered blender to blend until smooth.
  • Taste for seasoning and add more salt and pepper if needed.
  • Season with lemon juice and top with parmesan (if desired) before serving.


  • Carefully trim the asparagus and remove the lower woody stems before adding to the Instant Pot. The woody ends will not soften during cooking and will not blend well in the soup. 
  • Avoid overseasoning the soup. Chicken stock can be salty to season lightly, then taste and adjust after cooking. 
  • Cooking times do not account for the time that it takes for the Instant Pot to come up to pressure or for the pressure to release.
  • Storage - store soup in an airtight container inside the fridge for up to 4 days. 
  • There are 2 Blue Plan SmartPoints in one serving of this.
