Step 1

Select the Sauté setting on the Instant Pot, add the oil, and heat for 1 minute. Add the onion, garlic, carrots, celery, and salt. Sauté for about 10 minutes, until the vegetables give up some of their liquid and begin to brown just a bit. Stir in the tomato paste and nutritional yeast, then add 1 cup of the water and use a wooden spoon to nudge loose any browned bits from the bottom of the pot. Add the peppercorns, bay leaves, parsley, and remaining 7 cups water, making sure not to fill the pot more than two-thirds full.

Step 2

Secure the lid and set the Pressure Release to Sealing. Press the Cancel button to reset the cooking program. Then select the Soup/Broth setting and set the cooking time for 10 minutes at High pressure. (The pot will take about 20 minutes to come up to pressure before the cooking program begins.)

Step 3

Place a wire-mesh strainer over a large stainless-steel bowl. For a clearer broth, line the strainer with a double layer of cheesecloth.

Step 4

When the cooking program ends, let the pressure release naturally for 30 minutes, then move the Pressure Release to Venting to release any remaining steam. Open the pot and, wearing heat-resistant mitts, lift out the inner pot and pour the broth through the prepared strainer into the bowl. Discard the vegetables. Let the broth cool to room temperature. (To speed the cooling process, set the bowl in a larger bowl containing an ice bath.)

Step 5

The broth can be used right away, stored in an airtight container in the refrigerator for up to 3 days, or frozen for up to 6 months.

Step 6

Select the Sauté setting on the Instant Pot, add the oil and garlic, and heat for 2 minutes, until the garlic is bubbling but not browned. Add the onion and sauté for 5 minutes, until the onion is softened and the garlic is toasty and brown. Stir in the broth and use a wooden spoon to nudge loose any browned bits from the bottom of the pot. Stir in the carrots, ras el hanout, and the remaining 1 teaspoon salt. Stir in the beans, making sure all of the beans are submerged in the cooking liquid.

Step 7

Secure the lid and set the Pressure Release to Sealing. Press the Cancel button to reset the cooking program. Then select the Manual or Pressure Cook, or Bean/Chili setting and set the cooking time for 30 minutes at High pressure. (The pot will take about 15 minutes to come up to pressure before the cooking program begins.)

Step 8

When the cooking program ends, let the pressure release naturally (this will take about 40 minutes). Open the pot and stir in the tomato paste and lemon juice. Taste and adjust the seasoning with salt, if needed.

Step 9

Ladle the tagine into bowls. Drizzle with oil and sprinkle with mint. Serve hot, with couscous or flatbread.
