Step 1

In the Instant Pot, combine the carrots, mushrooms, onion, celery, rice, garlic, poultry seasoning, salt, and water.

Step 2

Secure the lid on the pot. Close the pressure-release valve. Select MANUAL and set the pot at HIGH pressure for 20 minutes. At the end of the cooking time, allow the pot to sit undisturbed for 10 minutes, then release any remaining pressure. Stir in the evaporated milk.

Step 3

Use an immersion blender to purée about half the mixture. Add water, if needed, to achieve desired consistency. Serve hot.
