Are kidney beans toxic?

In their raw form, kidney beans can be toxic. They contain a compound called phytohaemagglutinin that can cause severe vomiting and diarrhea if it’s not destroyed via cooking. That’s why it’s so important to fully cook red beans before eating them.

Do you need to soak kidney beans?

For dried kidney beans in particular, experts suggest soaking them for at least 5 hours before cooking. Whether or not you should soak beans in general is always up for debate. Some claim that soaking makes beans easier to digest, while others claim otherwise.

Personally, I like soaking beans because it promotes even cooking and shortens cooking time. If I’m making beans in the Instant Pot, however, I don’t soak them.

How long does it take to cook kidney beans?

On the stovetop, it takes between 45 and 90 minutes to cook kidney beans. However, depending on the soaking time and age of the beans, they may take less time to cook. They are finished cooking when they are tender and have a creamy texture. It’s normal for some beans to split open while others maintain their shape.

Cooking Kidney Beans Safely

The process of preparing kidney beans involves sorting, soaking, cooking, draining, and storing. It takes some time, but it’s super easy! Here’s everything you need to know about how to cook dry kidney beans.

Equipment

For soaking, you’ll need a large bowl. For cooking, gather a colander, Dutch oven or large pot, and a wooden spoon. You may also want to get out some containers for storage at this time.

Soaking Kidney Beans

Look through the kidney beans before soaking and remove any shriveled, damaged, or broken pieces. Then place the kidney beans in a large bowl. Make sure the bowl is big enough to account for the kidney beans expanding during soaking.

Add enough water to cover the kidney beans by a few inches. For one cup of dried beans, use about 4 to 6 cups water. For one pound of dried beans (about two cups), double that amount. Let the kidney beans soak for at least 5 hours or overnight.

Cooking Kidney Beans on the Stove

Drain the kidney beans from the soaking water. Place them in a large pot or Dutch oven. Add 10 cups of water if you are cooking a pound (about two cups) of kidney beans. Add two bay leaves if desired.

Bring the pot to a boil for a few minutes, then reduce heat to a simmer for about 45 minutes and up to 90 minutes. You’ll know kidney beans are cooked when they are tender and creamy. Some of them may split open.

Be sure to stir the beans every once in a while to promote even cooking. Check them for doneness at 30 minutes, since cooking times can vary depending on soaking time and age of the beans.

I like to add a teaspoon of salt about 10 minutes before I take the beans off the stove. Some people claim that salt prevents the beans from getting soft during cooking, so I add it towards the end to be safe.

Storing Cooked Kidney Beans

Drain the cooked beans, or use a slotted spoon to transfer the beans to storage containers. I like to use a slotted spoon so that I get a little bit of the liquid with the beans, but it’s up to you. I like how they get creamier when they’re stored in liquid. If you want to cool down the beans before storing, rinse them with cold water in a colander.

Since most recipes call for beans in 15-ounce cans, I like to store cooked kidney beans in portions of 1 and ¾ to 2 cups (about 15 ounces). This makes it really easy to add them to future recipes.

You can keep cooked beans in the fridge for up to a week. They last for up to 3 months in the freezer in airtight containers or silicone bags. You usually do not need to thaw frozen kidney beans before adding them to recipes, since they are commonly used in soups, chilis, and other cooked recipes. I don’t recommend using frozen beans in cold recipes like salads.

Ways to Use Red Kidney Beans

You can use cooked kidney beans in soups, chilis, tacos, and salads. They also make a great base for pureed bean dips and are the main ingredient in red beans and rice recipes!
