What if I don’t have an immersion blender?

You can use a blender or a food processor. Blend the soup in small batches, and please be careful as it will be very hot. Have a towel close by.

After blending, just add the soup back into the pot and continue with the finishing steps of the recipe.

I find an immersion blender very helpful in my kitchen. I highly recommend this one: Cuisinart CSB-75BC Smart Stick (affiliate).

How long does this soup last in the fridge?

This pressure cooker asparagus soup will keep for about 3 to 4 days, if it has been continuously refrigerated.

Does Instant Pot Asparagus Soup freeze well?

Yes! Freeze in covered airtight containers or heavy-duty freezer bags. To prevent curdling, stir well when reheating.
