Rinse 1 lb of dried beans under cool water using a colander to remove dirt or debris.
Place the rinsed beans into the pressure cooker. Add 8 cups of water or broth and 1 tbsp avocado oil, ensuring the beans are completely submerged.
If desired, add chopped onion, minced garlic, bay leaves, or any seasoning like chili powder.
Secure the lid and set the pressure cooker to high pressure for 35 minutes.
Once the cooking cycle is complete, allow the pressure to naturally release for 15-20 minutes.
After natural release, carefully open the steam valve to release any remaining pressure.
Open the lid, check the beans for tenderness, and serve. Drain excess liquid if needed.
