Ingredients
- Olive oil: for sautéing which adds a silky base and richness choose extra virgin for the best flavor.
- Fresh asparagus spears: trimmed to avoid woody parts which can be tough look for firm, bright green stalks.
- Yellow onion: chopped finely to soften during cooking and build a sweet aromatic foundation.
- Garlic cloves: chopped to release their pungent flavor which mellows with cooking.
- Fresh thyme: which imparts a subtle herbaceous note if you can find it fresh it makes a difference.
- Low-sodium chicken broth: to control the salt content and contribute a savory depth quality broth really shows here.
- Lemon zest and juice: bring brightness and a lightly tangy finish that balances the creaminess.
- Salt and pepper: seasoning to taste enhancing all the natural flavors without overwhelming them.
Step-by-Step Instructions
- Sauté the Aromatics:
- Heat olive oil in the Instant Pot using sauté mode. Add the chopped onion and asparagus pieces and cook for about five minutes until the mix becomes fragrant and the onions are translucent, which builds the flavor base.
- Add Garlic and Herbs:
- Stir in the chopped garlic and sauté for another minute. Then add fresh thyme to release its aroma. This layering of flavors ensures every element shines through.
- Cook Under Pressure:
- Pour in the low-sodium chicken broth along with the lemon zest and lemon juice. Secure the lid and set the Instant Pot to high pressure for five minutes. This quick cooking softens the asparagus perfectly while infusing all the flavors.
- Blend Until Smooth:
- After cooking, carefully quick-release the pressure. Use an immersion blender directly in the pot to puree the soup until completely smooth and creamy. Adjust seasoning with salt and pepper to your liking.

Fresh thyme can be replaced with dried but reduce the amount by half. For a dairy-free creamy touch, a small handful of cashews blended with the soup can add richness.
