Sort and Soak: Spread the dry white beans on a flat tray to remove any debris, then rinse thoroughly. Place them in a large bowl, cover generously with cold water, and soak overnight (or for at least 8 hours). (Forgot to soak them overnight? Check the Frequently Asked Questions section above for Mama's 1-hour "quick soak" emergency trick!)
The One-Pot Assembly: Transfer the soaked, rinsed beans to your pressure cooker. Add the 1.7 Liters of water, grated onion, crushed garlic, mixed herbs, tomato paste, olive oil, and all of the spices. There is no need to sauté! (Be sure to read the "Mama's Tips & Notes: Cooking Tips" section above to see why boiling your water in a kettle first is our ultimate time-saving hack!).
Pressure Cook: Secure the lid of the pressure cooker and place it on medium heat. Cook on low pressure for exactly 30 minutes.
Simmer and Thicken: Turn off the heat and safely release the pressure. Test a bean to ensure it is meltingly tender. If you want the sauce to be a bit thicker, simmer the stew uncovered on medium-low heat for 5 to 10 minutes. Stir gently every 2-3 minutes so it doesn't burn.
Serve: Serve piping hot with crusty bread or warm Batbout(Moroccan flat pan-bread). (Head up to the "Mama's Tips & Notes: Serving Tips" section in the post above to discover my secret smoked paprika flavor twist, and how we serve this when it's hot out during the summer!)
