If you’re wondering how long it takes to cook beans in Instant Pot, refer to this easy cheat sheet for cook times. For each type of bean, they were soaked overnight, cooked at High Pressure, then the Instant Pot heat was naturally released.
Keep in mind that while you will set your cook time to the amount noted, actual cooking will take longer since the pressure cooker takes about 10 minutes to reach pressure.
Soaked Pressure Cook Time – (No Soak Time)
Chickpeas (Garbanzo) 15 minutes (40 minutes unsoaked)
Kidney Beans 25 minutes (45 unsoaked)
Black Beans 22 minutes (35 unsoaked)
Pinto Beans 15 minutes (30 unsoaked)
Lobia (Black Eyed Peas) 15 minutes (30 unsoaked)
Black Chickpeas (Kala Chana) 20 minutes (40 unsoaked)
Cooking Note: Beans take longer to cook when cooked with acidic ingredients, like tomatoes, vinegar, or lemon juice. For example, Chickpeas cooked in seasoned water are done in 15 minutes, but in a recipe like Chana masala, which contains tomato and other acidic ingredients, they take 45 minutes.
