Here’s the safety nugget: you absolutely should not skip the boil for red kidney beans. They contain a toxin called phytohaemagglutinin, which survives quick soaks and can ruin your evening (think: heavy vomiting). But—and here’s the irony—the pressure cooker method kills that toxin faster than any overnight soak. So if you’re making chili with red kidney beans, use the Instant Pot method above, and cook them for a full 30 minutes at high pressure. Your stomach will thank you.
How To Cook Beans
For most other beans (black, pinto, navy, chickpeas), the quick boil-and-rest method is perfectly safe. The key is to never eat dried, raw beans, even if they’ve been soaked. Always cook them thoroughly. But you knew that. You’re a responsible bean eater.
The One Thing You Must Add to the Cooking Water
Here’s a pro tip that makes your skip-soak beans taste like you cared for days: add a strip of kombu (seaweed) or a pinch of baking soda to the cooking water. Kombu releases glutamates that make beans silky and tender and reduces the gas factor. Baking soda (just ¼ teaspoon per pound) softens the bean skins, so your quick-soaked beans won’t end up crunchy inside. (Don’t overdo the baking soda—it can make your beans taste soapy if you add a whole spoonful. Yes, I learned this the hard way. Soap beans are not a vibe.)
Also, salt your beans at the end, not the beginning. If you add salt too early, the skins can get tough and refuse to soften, which defeats the whole “no soak” rebellion we’re waging here. Add salt when the beans are fully tender, maybe 10 minutes before you turn off the heat.
