Step 1

Heat oil in pressure cooker. Add onions, garlic, carrots and celery. Saute until onions are softened and lightly browned, about 3-4 minutes. Add chili powder, cumin, coriander, oregano, mustard, and cayenne (if you like a little heat) and stir well for a minute or two. Add tomatoes, lentils, broth, salt to taste, and pepper. Pressure cook for 14 minutes or until lentils are tender.

Step 2

Select "Saute" setting on Instant Pot. Add oil and let heat up. Add onions, garlic, carrots and celery. Saute until onions are softened and lightly browned, about 4 minutes. Add chili powder, cumin, coriander, oregano, mustard and cayenne (if you like some heat) and stir well for a minute or two. Add tomatoes, lentils, broth, salt to taste, and pepper.

Step 3

Select "Cancel," then close the lid. Turn steam release handle to "Sealing" position. Select "Bean/Chili" and set time for 14 minutes (note: if you use red lentils, cooking time will be less ~ 7-8 minutes). Press "Cancel" and let Instant Pot naturally release pressure until float valve drops down and lid unlocks; alternatively, press "Cancel" and let Instant Pot naturally release for 10 minutes; then turn steam release valve to "Venting" until float valve drops down and lid unlocks.
