Do canned beans need to be rinsed before eating?

6 min read

According to the Bean Institute, rinsing canned beans can reduce their sodium content by up to 41%. This simple act of preparation begs the question: Do canned beans need to be rinsed before eating, or is it an unnecessary step for your meal?

Quick Summary

Deciding whether to rinse canned beans depends on your recipe and dietary needs. The practice can significantly lower sodium and improve flavor control, but the liquid is sometimes a beneficial ingredient.

Key Points

  • Reduce Sodium: Rinsing canned beans can reduce their sodium content by up to 41%, which is beneficial for those monitoring salt intake.

  • Improve Flavor: Rinsing removes the salty, starchy canning liquid, giving you more control over the dish's flavor profile.

  • Enhance Texture: Removing the gel-like liquid prevents a slimy mouthfeel, leaving the beans with a firmer, cleaner texture.

  • Skip for Thickening: For recipes like soups, chilis, and creamy sauces, the canning liquid can be used as a natural thickener.

  • Save for Aquafaba: The liquid from canned chickpeas (aquafaba) is a great vegan egg white substitute for meringues and other desserts.

  • It Depends on the Recipe: The decision to rinse or not depends entirely on your recipe and desired culinary outcome.

Should you rinse canned beans?

The short answer is: it depends on your goals and the dish you are preparing. While rinsing is not strictly required for safety, doing so offers significant culinary and nutritional benefits. The liquid, often called aquafaba when from chickpeas, contains a lot of starch and added sodium, which can impact the final dish's taste and texture. Therefore, making an informed decision about whether to rinse will help you achieve the best results in your cooking.

Why you should rinse canned beans

Rinsing is a popular practice among chefs and home cooks for several reasons. Primarily, it's about controlling flavor, texture, and sodium levels in your food.

Reduce sodium content

Many canned beans contain high levels of added sodium for preservation and flavor. A quick rinse can remove a significant portion of this salt, giving you more control over the seasoning of your dish. This is particularly important for individuals monitoring their sodium intake, such as those with high blood pressure. The Bean Institute notes that draining and rinsing can wash away a substantial amount of the salt. For example, studies have shown that rinsing can reduce sodium by as much as 40%. This is a crucial step for making a healthier meal without sacrificing the convenience of canned goods.

Improve flavor and consistency

The liquid inside a can of beans is a salty, starchy brine that can interfere with the flavors of your other ingredients. By rinsing the beans, you start with a neutral base, allowing the true flavors of your herbs, spices, and sauces to shine through. This is especially important for recipes where the beans are not the star ingredient. Additionally, the thick, gelatinous nature of the canning liquid can alter the texture of a dish, making it slimy or unappealing. Rinsing removes this residue, leaving the beans clean and fresh.

Decrease gassiness

Beans contain oligosaccharides, a type of sugar that can be difficult for the human body to digest, leading to gas and bloating. The good news is that many of these compounds leach into the canning liquid. By draining and rinsing your canned beans thoroughly, you can wash away some of these gas-causing agents, potentially making your dish easier on the digestive system. While rinsing canned beans may not be as effective at reducing gas as soaking dried beans overnight, it can still help those with sensitive stomachs.

When to skip the rinse

While rinsing offers many benefits, there are specific situations where you might want to skip this step. For some recipes, the canning liquid is a valuable asset.

  • For thickening soups and stews: The starchy liquid from the can can act as a natural, flavorful thickener. In recipes for chili, soup, or stews, the extra body and flavor from the bean liquid can enhance the final product. Using the liquid can help you achieve a richer, more velvety consistency without needing to add other thickening agents.
  • For making creamy hummus: When making hummus, the liquid from a can of chickpeas, known as aquafaba, can be reserved and used to achieve a super-creamy texture. It can also be a key ingredient for emulsifying the hummus, making it smooth and delicious.
  • For aquafaba-based recipes: Aquafaba has become a popular vegan egg white substitute. It can be whipped into stiff peaks to create meringues, mousses, and other desserts. In this case, you will want to drain the beans but save the liquid specifically for use in another recipe.
  • When using low-sodium or no-salt-added beans: If you're using canned beans that are labeled as 'low-sodium' or 'no-salt-added,' you've already addressed the primary health reason for rinsing. In these cases, the decision to rinse comes down to flavor and texture preferences, not a need to remove excess salt.

How to rinse canned beans effectively

Rinsing canned beans is a quick and straightforward process that can make a big difference in your cooking. Here is a simple, step-by-step guide:

  1. Open the can: Use a can opener to open the can and set up a colander or fine-mesh sieve in your sink.
  2. Drain the liquid: Pour the entire contents of the can into the colander, allowing the canning liquid to drain completely into the sink. Shake the colander gently to remove as much liquid as possible.
  3. Rinse with water: Place the colander under cool, running water. Move the beans around with your hands or a spoon to ensure all surfaces are rinsed thoroughly. Continue rinsing until the water running through the colander is clear, which may take up to a minute.
  4. Pat dry (optional): For some recipes, particularly those where you want crispy beans or need to control moisture, patting the beans dry with a paper towel can be beneficial.

Comparison: Rinsed vs. Unrinsed Canned Beans

Feature Rinsed Canned Beans Unrinsed Canned Beans
Sodium Reduced by up to 41% Can contain up to 500 mg per serving or more
Flavor Neutral and clean; better flavor control Salty, which can overpower a dish
Texture Firm and distinct; no slimy residue Often slimy or gel-like due to starch
Gassiness Potentially reduced, as some oligosaccharides are washed away Possibly higher risk of gas for some individuals
Dish Use Salads, wraps, side dishes, crispy snacks Soups, chilis, creamy sauces, hummus
Prep Time Requires an extra minute for rinsing Instant; no extra time or equipment needed

Conclusion: The Final Verdict

Ultimately, whether you do canned beans need to be rinsed before eating is a culinary and dietary choice. For most everyday applications like salads, casseroles, or side dishes, rinsing is highly recommended to control sodium and improve flavor and texture. For thick, hearty dishes like soups and chilis, the starchy liquid can be a desirable element that adds depth and body. Knowing these nuances allows you to use canned beans more effectively, transforming them from a simple convenience food into a versatile and intentional ingredient in your cooking. Start with a rinse for a healthier, cleaner-tasting dish, and only skip it when the recipe specifically benefits from the canning liquid.

When should I rinse canned beans? A detailed breakdown

When to rinse

  • Health Concerns: If you or someone you're cooking for has high blood pressure or is on a sodium-restricted diet, rinsing is a must to significantly reduce salt intake.
  • Culinary Control: For recipes where you want complete control over the seasoning, rinsing provides a neutral base to build your flavors from.
  • Texture Matters: When preparing dishes like bean salads, wraps, or crispy roasted chickpeas, rinsing and drying the beans will prevent a gummy or slimy texture.

When not to rinse

  • Adding Body to Sauces: When a recipe calls for a thick, hearty sauce, like in a chili or a stew, the starchy liquid from the can can serve as a natural thickener.
  • Making Creamy Hummus: For extra creamy hummus, reserving and using the chickpea canning liquid (aquafaba) can help achieve the perfect smooth consistency.
  • Specialty Recipes: If a specific recipe, like one using aquafaba as an egg white substitute, requires the canning liquid, you should follow the instructions.
  • Low-Sodium Cans: If you're using low-sodium or no-salt-added beans, the main reason for rinsing is eliminated, leaving the choice purely to your flavor and texture preference.
