Instant Pot Rio Zape Beans

  • Author: Mike Vrobel
  • Total Time: 1 hour 5 minutes
  • Yield: 6 cups beans 1x


Instant Pot Rio Zape Beans. A classic heirloom bean from the Southwest, ready in about an hour thanks to pressure cooking.


  • 1 pound dried Rio Zape beans, sorted and rinsed
  • 6 cups water
  • 1 teaspoon fine sea salt
  • ½ teaspoon baking soda
  • 1 onion, peeled and halved
  • 1 bay leaf


  1. Sort and rinse the beans: Sort the Rio Zape beans, removing broken beans, stones, and any other non-bean material. Put the beans in a strainer, rinse the beans, and set them aside to drain.
  2. Everything in the pot: Pour the beans into an Instant Pot or other pressure cooker. Stir in 6 cups of water, 1 teaspoon of fine sea salt, and ½ teaspoon of baking soda. Add the onion halves and bay leaf, and lock the lid on the cooker.
  3. Pressure Cook for 35 minutes with a Natural Release: Pressure cook on high pressure for 35 minutes in an electric pressure cooker ("Manual" or "Pressure Cook" mode in an Instant Pot), or 30 minutes in a stovetop PC. Let the pressure come down naturally; you can quick release any remaining pressure after 15 minutes if you’re in a hurry.
  4. Serve or Save: Remove the onion and bay leaf and discard. Serve the beans as-is in their broth, freeze in their broth for later (see Storage section for freezing details), or drain and use them as directed in another recipe.
