Should You Drain Black Beans

Should you drain black beans?

Yes, you should drain black beans in most cases because the liquid they’re packed in can be starchy, salty, and full of compounds that affect both flavor and digestion.
 
Whether you’re working with a can of black beans or a pot you cooked from scratch, knowing when and why to drain them makes a real difference in your final dish.
 
If you’ve been asking yourself whether you should drain black beans before adding them to soups, salads, or burritos, you’re in the right place.
 
In this post, we’ll look at why draining black beans is usually the right move, when you might actually want to keep that liquid, and how to drain them the right way.
 
Let’s dig in.

Why You Should Drain Black Beans

You should drain black beans because the liquid that surrounds them—whether it’s canning liquid or cooking water—doesn’t do your recipe any favors most of the time.
 
Here’s why draining black beans matters:

1. The Liquid Is Starchy and Thick

When black beans sit in liquid, whether in a can or a pot, starches leach out of the beans and into the water.
 
That starchy liquid can turn your dish cloudy and gluey in a way you didn’t intend.
 
If you’re making a salad, for example, you want black beans that are firm and clean, not coated in a syrupy residue that makes everything look muddy.
 
Draining black beans removes that starchy liquid so your dish stays fresh and the texture stays exactly where you want it.

2. Canned Liquid Is Loaded With Sodium

If you’re using canned black beans, that liquid is basically a salt bath.
 
Canning liquid often contains added salt, and a good chunk of it stays in the liquid rather than in the beans themselves.
 
So when you don’t drain black beans from a can, you’re pouring extra sodium straight into your recipe.
 
If you’re watching your salt intake, draining black beans and giving them a quick rinse is one of the easiest ways to cut back without losing any flavor.

3. Rinsing Reduces Gas-Causing Compounds

Black beans contain oligosaccharides, which are sugars your body can’t fully break down.
 
These compounds are a big reason beans have a reputation for causing bloating and gas.
 
The good news is that some of these oligosaccharides end up in the liquid, so draining and rinsing black beans can help reduce that effect.
 
It won’t eliminate it completely, but if beans tend to bother your stomach, rinsing after you drain black beans is a simple habit that can make mealtime a lot more comfortable.

4. Flavor Stays Cleaner

That murky canning liquid has a slightly metallic, salty taste that can throw off the flavor of whatever you’re cooking.
 
When you drain black beans, you’re left with the beans themselves—earthy, creamy, and ready to absorb whatever seasonings you add.
 
That’s why dishes made with properly drained black beans taste brighter and more intentional than ones where the liquid gets dumped in along with the beans.

When You Might Not Drain Black Beans

There are a few situations where you shouldn’t drain black beans, and it’s worth knowing them so you don’t toss out something useful.
 

1. You’re Making a Thick Stew or Chili

If you’re simmering a hearty chili or a thick bean stew, that starchy liquid can actually work in your favor.
 
It adds body and helps the dish thicken naturally without any extra thickeners.
 
In this case, you don’t have to drain black beans completely—just pour in the whole can and let the liquid cook down.

2. You’re Using Unsalted Home-Cooked Beans

If you cooked your own black beans without salt, the cooking liquid is basically bean broth.
 
It’s flavorful, low in sodium, and great for soups.
 
So if you’re wondering whether to drain black beans you cooked yourself, taste the liquid first—if it’s tasty, keep it.

3. You Want Aquafaba-Style Liquid

The liquid from canned beans, sometimes called aquafaba, can be whipped or used as a binder in certain recipes.
 
It’s more common with chickpeas, but black bean liquid can work in a pinch for thickening sauces or vegan baking.
 
Just keep in mind the color will be darker, so it’s best for dishes where that doesn’t matter.

How to Drain Black Beans Properly

Draining black beans takes about thirty seconds, but doing it right makes a difference.
 

1. Use a Colander or Strainer

Pour the can or pot into a fine-mesh strainer or colander.
 
The holes should be small enough that you don’t lose any beans down the drain.

2. Rinse With Cold Water

Once they’re drained, give the beans a quick rinse under cold running water.
 
This washes away leftover sodium and surface starches, and it cools the beans down if they’re coming straight from a hot pot.

3. Shake Off Excess Water

Give the strainer a good shake or pat the beans dry with a paper towel.
 
Excess water can make salads soggy or dilute sauces, so a few extra seconds here pays off.

4. Use Them Right Away or Store Them

Drained black beans are best used within a day or two.
 
Store them in an airtight container in the fridge if you’re not cooking with them immediately.

So, Should You Drain Black Beans?

You should drain black beans in most recipes because the liquid adds starch, sodium, and compounds that can cause gas, while the beans themselves stay cleaner and tastier without it.
 
That said, there are times when keeping that liquid makes sense—like in chili, stews, or when you’re working with unsalted home-cooked beans.
 
The bottom line is simple: if you want control over flavor and texture, drain and rinse your black beans.
 
If you want extra body in a simmered dish, let the liquid stay.
 
Either way, now you know exactly when and why draining black beans is the right call.
