Instructions
Turn on the Instant Pot and press the Sauté function key. Add the olive oil, butter, onions, and salt and cook for 3-4 minutes, stirring a few times, until softened.
Add the rest of the ingredients (except for cream, extra garlic, and lemon) and stir through. Press Keep Warm/Cancel.
Place the lid and lock. Press Manual, High Pressure, and set for 10 minutes. After three beeps the Instant Pot will begin to build up the pressure and start cooking. Once the cooking finishes, release the pressure naturally for 5 minutes before using quick release to let off the rest of the steam.
Remove the thyme sprigs from the soup and add in the extra chopped garlic. Stir through. Transfer the soup in 2-3 batches to a food processor or a blender. Cover with a lid and process into pureed soup texture (doesn’t have to be completely smooth and can have finely diced mushrooms still in). Pour the pureed soup to another saucepan or a large bowl while you process the rest of the soup. Then combine all of the puréed soup in a pot and stir in the lemon zest, lemon juice and cream.
Serve with a swirl of cream on top. If you like, pan-fry a few sliced mushrooms in butter and serve over the top. It’s lovely as is or with some crusty bread and butter on the side.
