Start by setting your Instant Pot to the sauté function. Add 2 tablespoons of olive oil and let it heat up. Once hot, add the diced onion and minced garlic. Sauté for about 3-5 minutes, or until the onion becomes translucent and fragrant.
Next, add the ground Italian sausage to the pot. Use your wooden spoon to break it up as it cooks. Brown the sausage for about 5-7 minutes, until it is nicely cooked through and no longer pink.
Now, sprinkle in the kosher salt, paprika, dried oregano, and ground cumin. Stir well to combine all the flavors, allowing the spices to bloom in the heat for about a minute.
After the spices are aromatic, add the soaked beans and pour in the 8 cups of low-sodium chicken stock. Give everything a good stir to ensure the beans are well-distributed.
Close the lid of the Instant Pot and make sure the valve is set to sealing. Cook on high pressure for 25 minutes. Once the timer goes off, allow the pressure to release naturally for 10 minutes before carefully switching the valve to venting to release any remaining pressure.
Finally, open the lid and stir in the torn kale. Allow it to wilt in the hot soup for about 5 minutes. This will keep the kale vibrant and packed with nutrients.
Ladle the soup into bowls and serve warm. It pairs wonderfully with crusty bread or a simple side salad. Enjoy the comforting flavors of your Instant Pot Sausage Bean and Kale Soup!
