Sauté onion- Select the ‘sauté’ function of your Instant Pot. Add the olive oil and onion to the stainless steel insert, and cook for 5 or so minutes, until onion is soft and translucent.
Add garlic- Make a space in the middle of the pot, and add the garlic. Cook for 1 minute until garlic is fragrant.
Deglaze the pan + add ingredients- Add 1 cup of stock to the pan, and use the spatula to scrape the bottom and remove anything that might be sticking.Add the rest of the stock, the cauliflower, celery, thyme and salt. Stir to combine. Cook + 10 minute natural pressure release- Place the lid on the Instant Pot, set the steam release handle to ‘sealing’, and pressure cook on high pressure for 5 minutes.When the Instant Pot beeps, allow it to sit for 10 minutes before releasing any remaining pressure.
Add milk + purée- Add the milk to the pot, then use an immersion blender to blend it smooth.
Add cheese- Add the cheese by the handful, and stir it in until melted into the soup. Remove the stainless steel pot from the Instant Pot and serve up the soup.
