A flavorful and nourishing soup done in the Instant Pot. No need to pre-soak the beans means one less step to run under. Make it meaty using Italian sausage, or leave it out for a very tasty vegetarian soup. Plenty of grated Parmesan just before serving is the finishing touch. When considering total cooking time, remember that it will take a while for the Instant Pot to come to pressure before it kicks into cooking mode.
Add the cannellini beans, garlic, tomatoes with their juices, chicken broth, bay leaf, oregano, fennel, thyme, and the rind of the Parmesan cheese. Put on the lid to the Instant Pot, be sure the valve is closed, and set it to “Manual” (high pressure) for 1 hour.
Open the lid and taste a couple of beans to make sure they are tender. (If not, cook on Manual for another 5 to 10 minutes and check again).
When the soup is done, remove the Parmesan rind and bay leaf and discard. Add the kale, sausage, and salt and stir well. The hot broth will wilt the kale within about 5 minutes.
