Ingredients You’ll Need
Notes on Ingredients
butter: for flavor and to help onions sauté, can substitute with olive oil or ghee
onion: use a yellow onion for the best flavor, but white will work as well!
asparagus: fresh asparagus will lend the best flavor, but frozen could work as well
vegetable stock: for flavor, can substitute for chicken stock or mushroom broth
heavy cream: for creaminess and flavor, can substitute with Greek yogurt
lemon juice: fresh lemon juice is best, but can use bottled
Salt and pepper: not pictured above but essential for flavor!

How to Make Instant Pot Asparagus Soup
Sauté butter, onion and garlic until softened and fragrant. Then add asparagus and sauté for 3 minutes.
Add vegetable broth (having enough liquid is essential for pressure cooking).
Pressure cook. Secure lid onto Instant Pot and pressure cook for five minutes. Quick release pressure.
Transfer soup into a high speed blender (or use an immersion blender) and blend until smooth and creamy.
Stir in lemon juice and heavy cream (or Greek yogurt).
Season with salt and pepper and enjoy!
If you don’t have an Instant Pot, you can make this recipe in theslow cooker! Just add all ingredients (except heavy cream and lemon juice) to slow cooker and set to low for 7-8 hours or high for 3-4 hours. Once asparagus is soft, transfer to a blender (or use an immersion blender), add heavy cream and lemon juice and blend. You can get the full recipe for slow cooker asparagus soup here.
If you can’t get fresh asparagus, frozen or canned work as well!
If using Greek yogurt, be sure to use room temperature yogurt (let sit out for at least 1 hour but not more than 2 hours) so it doesn’t curdle. I like using plain, full fat Greek yogurt in this recipe but you can use your preferred Greek yogurt.
What if I don’t like asparagus?
Unfortunately this is an asparagus soup, but you could sub for green peas, broccoli, bok choy, or zucchini.
Is this soup vegan?
As long as you use olive oil instead of butter and omit the heavy cream (or yogurt), this asparagus soup is vegan! To add some creaminess to the soup’s texture, you can use canned coconut milk, soaked cashews, or potato for thickening.
Is this soup healthy?
This creamy Instant Pot asparagus soup is packed with nutrition. Asparagus is an excellent source of vitamin K and B vitamins and is a good source of vitamin C. The soup is also naturally vegetarian and gluten-free.
Why is my asparagus soup stringy?
You may have used too thick / woody pieces of asparagus. Make sure to trim the ends of your asparagus before using. Bend the thick end of the asparagus spear until it snaps – discard, compost, or freeze the woody stems (if you freeze, you can use to make a vegetable stock later on).
Storage and Preparation
This asparagus soup will stay fresh for 3-4 days in the refrigerator when stored in an air-tight container. You can reheat the soup in your microwave or over low heat on the stove. Heat until just warmed through, and stir well to avoid hot spots.
This creamy Instant Pot soup can also be frozen! Store in an airtight container in the freezer for up to 3 months. Defrost overnight in the refrigerator or in the microwave.
