The recipe usually says to drain and rinse canned beans before you use them, but do you really need to? It's a fair question and one, surprisingly, that evokes plenty of opinions. I tapped into my own experiences as a chef and registered dietitian and also reached out to a few of my colleagues to get their advice. Here's what we have to say.
Rinsing Canned Beans, From a Nutrition Perspective
Instinctively, I find myself almost always draining and rinsing my canned beans. This might have something to do with the fact that for years, while working primarily as a dietitian, I told people to do just that. My reasoning was (and mostly still is) that canned beans (not low-sodium or salt-free), can be high in sodium.
If you're a relatively healthy person though, enjoying canned beans without draining or rinsing them first is fine. That's because our bodies require sodium to function. It's only when we go above and beyond what we need that it becomes a problem. Beyond sodium, beans provide potassium, an important electrolyte for heart health, that, according to research, may help offset the effects of sodium on blood pressure, says Monica Reinagel, MS, LDN, and host of “The Nutrition Diva” podcast.
But if you're someone who needs to watch your sodium intake, it certainly can't hurt to drain and rinse canned beans before using them. Doing so can reduce the sodium by 40%. If you don't want to rinse, consider at least draining them first. Draining alone will “reduce the sodium by a third,” says Reinagel. Bottom line: If you're watching your sodium intake for your health, it won't hurt to drain and rinse your can of beans before using them. Or better yet, buy low-sodium or no-salt-added varieties.
Because of my training, I know that salt plays a vital role in bringing out the flavor of food. In culinary school, I gained appreciation for the nuances of when and how to add it, but this can be hard to do if you’re starting with a can of heavily salted beans. That's why I advise my clients to drain and rinse to begin, leaving room forseasoning and tasting as they go.
But it's not just the salt that's of concern, it's also the liquid. Canned beans are packed in a solution of water, salt, and starch. That solution can leave a glossy film on the beans, interfering with not only mouthfeel (slimy beans are a little off-putting), but also the ability of the beans to cling to other ingredients in the dish and absorb those flavors.
What Other Experts Say About Rinsing Canned Beans
While opinions varied among my colleagues, chef and registered dietitian Abbie Gellman is all or none, saying that she typically rinses and drains canned beans whenever she uses them. Not draining and rinsing them can add viscosity, liquid, and/or flavor to a dish, she says, which isn't always something she wants for a recipe.
But Gellman is a bit of an outlier. Most pros answer with, “It depends.” Dana Angelo White, MS, RDN says it has everything to do with what she’s making. "For salads, burritos, and pasta dishes, I always rinse,” she says. “Rinsed and drained beans mix easily with other ingredients, plus the sodium is reduced. On the other hand, hummus, soup, and chili may benefit from a splash or two of that starchy and flavorful liquid." Registered dietitian Frances Largeman-Roth agrees. " “If you don't rinse them,” she says, “just keep in mind that they've already been salted."
The Canned Beans Bottom Line
The choice is ultimately yours. If you're trying to limit your salt intake, draining and rinsing your canned beans before using them is never a bad idea. If you're a purist like me–who wants to be in control of the amount of added salt (while skipping the glossy film) in your dish–then yes, drain and rinse those beans first. But know that it's not wrong to use them straight out of the can. Because why waste water and dirty a strainer if you don't necessarily have to?
Canned beans are packed in a solution of water, salt, and starch. That solution can leave a glossy film on the beans, interfering with not only mouthfeel (slimy beans are a little off-putting), but also the ability of the beans to cling to other ingredients in the dish and absorb those flavors.
The liquid in good canned beans is just the water and salt the beans were cooked in… filled with delicious bean flavor. And this liquid is a great thickener for not only the specific dish you're making at the moment, but for any dish that could use some thickening, some salt, and some bean flavor.
Draining and rinsing canned beans can reduce their sodium content by more than 40%. But taking just a few extra minutes is key to getting the most benefit. First, drain beans in a colander for two minutes. Then rinse the beans under cool running water for 10 seconds.
The reason that beans are safe to eat straight from the can is pretty simple: They're already cooked. Per Epicurious, beans are blanched before being canned with water, salt, and other additives, and then sealed and cooked under steam pressure at a high temperature before landing at your local grocery store.
Rinsing beans after they are drained ensures that all residual sodium adhering to the bean's surface is removed and results in the highest reduction. All brands and all classes of beans tested demonstrated significant reductions in sodium by either draining or draining and rinsing.
Many people wonder if they need to drain and rinse canned beans, and the answer is, “it depends.” It's fine to add the bean liquid to many recipes, but if you want to reduce the amount of sodium, it's best to drain and rinse canned beans.
But most people can enjoy more beans with less gas with the help of these tips: Soak beans overnight in water, then drain, rinse and cook in fresh water. This decreases the oligosaccharide content. Cooking the beans in a pressure cooker may reduce the oligosaccharides even further.
Officially called aquafaba, the liquid included in cans of beans is typically starchy and salty, though those qualities differ based on the brand of beans. Feel free to dip a spoon or finger in to taste it before using. “It has a viscous body from the fibers of the beans.
Black beans are naturally low in sodium and contain potassium, calcium, and magnesium, all of which have been found to decrease blood pressure naturally. Be sure to purchase low sodium canned options and still drain and rinse to further reduce sodium content.
To cut down on the gassy properties, you can add a little baking soda to your recipe. The baking soda helps break down some of the beans' natural gas-making sugars. I tested this while fixing one of my favorite slow cooker recipes: red beans and sausage.
Modern cooking websites often say it doesn't matter. In a way, they're both right. Soaking beans can help improve the texture of the final product once the beans are cooked and reduce the gas produced when the food is being digested. But it isn't necessary to soak them.
Ultimately though, if you look through all the literature, here is what it boils down to: Despite slight differences, most studies agree that both home-cooked dry beans and canned beans are very healthful choices.
One can of canned beans can contain up to 25% of the recommended daily intake of salt (570 mg). Canned beans are safe to eat and provide many health benefits. Nevertheless, there is a low risk that canned foods may be a source of excess salt, nitrates, nitrites, and heavy metals that may pose human health risks.
Nutrition experts talk about the benefits of this oft-overlooked pantry staple. Eating a few servings of beans a day can help you reach your recommended daily fiber intake of 21 to 25 grams for women and 30 to 38 grams for men.
Unless the recipe tells you to keep the canned beans in their liquid, you should drain your can and give the beans a good rinse before using. This will improve the flavor and texture of your finished dish. Open your cans of beans using a can opener.
Pour the beans directly into the pot and season for how you plan to use them. Allow it to simmer, stirring occasionally. Continue to stir and heat beans until they reach the desired temperature and consistency, about 5-10 minutes.
In order to properly reduce the sodium from canned beans, it is important to rinse them correctly. "Draining and rinsing canned beans can reduce their sodium content by more than 40 percent. But taking just a few extra minutes is key to getting the most benefit," The Bean Institute website states.
Rinsing beans can improve the flavor and texture of the final dish and can help cut down on how much gas they produce. So, for your culinary success and intestinal comfort, give those canned beans a rinse unless your recipe specifically says not to.
Trials were conducted on five bean types: kidney, black, faba, navy and pinto. The use of 1-2% salt reduced cooking time* and improved the flavour, texture and appearance of cooked beans.
The starchy leftover liquid from canned beans or simmered dried beans can also be used as a substitute for any stock or broth or added to thicken soups, stews and sauces. Freeze extra liquid for later use.
