How Long To Cook Adzuki Beans

How long to cook adzuki beans depends on whether you’re using dried beans or canned ones, and whether you’re cooking them on the stovetop, in a pressure cooker, or in a slow cooker.
 
If you’re starting with dried adzuki beans, they typically take about 45 to 60 minutes to cook on the stovetop after soaking.
 
Canned adzuki beans are already cooked, so they just need a quick warm-up of about 5 to 10 minutes.
 
In this post, we’ll break down exactly how long to cook adzuki beans using different methods, plus a few tips so they turn out perfectly tender every time.
 
Let’s get into it.
 

How Long to Cook Adzuki Beans on the Stovetop

If you’re wondering how long to cook adzuki beans on the stovetop, the answer is roughly 45 to 60 minutes once they’ve been soaked.
 
Here’s what affects that cooking time:
 

1. Soaking Makes a Big Difference

If you soak your adzuki beans overnight, they’ll cook in about 45 to 60 minutes.
 
If you skip soaking, you’re looking at closer to 60 to 90 minutes because the beans need extra time to soften.
 
So if you want to know how long to cook adzuki beans without soaking, plan for at least an hour and a half.
 

2. Simmer, Don’t Boil Hard

Once your adzuki beans come to a boil, reduce the heat to a gentle simmer.
 
A hard boil can split the skins and make the beans mushy on the outside while still firm inside.
 
A steady simmer is the key to getting them evenly tender.
 

3. Check Them Around the 40-Minute Mark

How long to cook adzuki beans really comes down to texture, so start tasting them at around 40 minutes.
 
They should be soft but still hold their shape.
 
If they’re still a bit chalky in the center, give them another 10 to 15 minutes.
 

How Long to Cook Adzuki Beans in a Pressure Cooker

If you’re using a pressure cooker or Instant Pot, the answer to how long to cook adzuki beans gets a lot shorter.
 
Here’s how it works:
 

1. Soaked Beans Take About 5 to 7 Minutes

Soaked adzuki beans cook in just 5 to 7 minutes at high pressure.
 
Add about 3 cups of water for every cup of dried beans, then let the pressure release naturally for 10 minutes.
 

2. Unsoaked Beans Take 15 to 20 Minutes

No time to soak?
 
You can still cook adzuki beans in a pressure cooker in about 15 to 20 minutes at high pressure.
 
Just add a little extra water since unsoaked beans absorb more.
 

3. Natural Release Matters

After the cooking time is up, let the pressure come down on its own for at least 10 minutes.
 
Quick-releasing too soon can cause the beans to split and lose their texture.
 

How Long to Cook Adzuki Beans in a Slow Cooker

The slow cooker is hands-off, but it does take the longest.
 
Here’s what to expect:
 

1. Soaked Beans Need 3 to 4 Hours on High

Soaked adzuki beans cook in about 3 to 4 hours on high or 6 to 8 hours on low.
 

2. Unsoaked Beans Need 6 to 8 Hours on High

If you didn’t soak them, plan for 6 to 8 hours on high.
 

3. Keep the Lid On

Every time you lift the lid, you lose heat and add time.
 
So resist the urge to peek and just let them do their thing.
 

How Long to Cook Canned Adzuki Beans

Canned adzuki beans are already cooked, so how long to cook them is really just about heating them through.
 
Here’s the quick version:
 

1. Stovetop Takes 5 to 10 Minutes

Drain and rinse the beans, then warm them in a saucepan over medium heat for 5 to 10 minutes.
 

2. Microwave Takes 2 to 3 Minutes

In a microwave-safe bowl, canned adzuki beans heat up in about 2 to 3 minutes, stirring halfway.
 

3. Don’t Overcook Them

Since they’re already soft, cooking them too long turns them into mush.
 
Just heat until warm and you’re done.
 

So, How Long to Cook Adzuki Beans?

How long to cook adzuki beans depends on your method, but the good news is none of them take very long.
 
On the stovetop, soaked adzuki beans take about 45 to 60 minutes.
 
In a pressure cooker, that drops to just 5 to 7 minutes.
 
A slow cooker takes 3 to 4 hours on high, and canned beans only need 5 to 10 minutes to warm up.
 
So whether you’re making red bean paste, a hearty soup, or a grain bowl, you now know exactly how long to cook adzuki beans for perfect results.
