Instant Pot Lentil Soup is a homey, comfortfood in a bowl. It's healthy, nourishing to thesoul and body, and incredibly delicious with paprika and cumin.
Set the pressure cooker to Sauté and drizzle in the oil. Once it's hot, add the onion and stir it into the oil. Cook, stirring frequently, until soft; about 4 minutes.
Then add the carrots, celery, salt, smoked paprika, cumin, black pepper, and red pepper flakes. Sauté until the carrots and celery are beginning to soften; about 2 minutes.
Cancel the Sauté function. Stir in the lentils and garlic and let cook in the residual heat for another 30 seconds before adding the tomatoes and broth.
Cover and seal the Instant Pot. Cook on HIGH pressure for 15 minutes. Then let naturally release the pressure.
Open the lid and stir the soup. Taste and adjust the seasonings as desired. Serve hot with fresh parsley for garnish and a sprinkling of Parmesan cheese if desired.
