Ginger and Spring Onion Njahi Stew

I have always been fascinated by how njahi seeds look when raw. Like a small black bag with a neat white zip placed halfway on its side. Or like a tiny  black pod with a strip of white paint. Or like a compressed skunk. They are kinda cute actually. They are black and white when uncooked but once they are cooked, they transform to this amazing deep mahogany shade. God is really creative with everything he does or made for us, don’t you think?  I am not aware exactly where else in the world this seed can be found. From my online sources, they referred  to as lablab beans; a name that is as funny as it is strange. Some people call them tuxedo beans, while others call them hyacinth beans. There are white ones, brown, black ones and even red ones but the popular ones in my country are the black ones.

In my country, these seeds are most commonly consumed by communities from the mount Kenya region. They have slowly gained popularity throughout the nation mainly due to their nutritional benefits. Some of the these its high in protein, folate, iron ,vitamin B6, zinc, calcium,magnesium and phosphorus. They are usually prepared with just onions, tomatoes and some light seasoning. But as you know, here, we always take it up another notch. This njahi recipe has plenty of flavor, which plays up the natural earthy flavor of these beans. I am really excited to share this recipe with you 🙂

Ingredients for the best njahi ever

njahi stew ingredients_njahi reciepe_Kaluhis Kitchen_Top Kenyan Food Blogger

200ml of coconut milk

2 tablespoons of whole cumin seeds

3 tomatoes, diced

1 red onion, finely diced

Spring onion, finely diced

150 Grams of Njahi seeds

1 green bell pepper, finely diced

5 cloves of garlic + half of a thumb sized size of fresh ginger root, minced

2 tablespoons of royco all spice mix (or your choice of all spice mix)

2 tablespoons of tomato paste

Salt and pepper for seasoning

Fresh coriander for garnishing, finely chopped


These njahi beans take a long time to boil. To shorten this time, soak them in plenty of water  overnight. This will allow them to absorb the water and soften them a great deal. They will swell and turn dark brown. After that time has lapsed, drain the water, give them a good rinse and place them in your sufuria with fresh water ready for boiling.

To this add your whole cumin seeds which will boil with the njahi. Boiling these together will give the njahi their own flavor even without adding any spice.  I bought mine from Tuskys on Kenyatta Avenue. Read the health benefits of whole cumin seeds here.

After the beans are 3/4 done, add some water and the coconut milk. This will make the beans even tastier and build a very nice flavor profile. I always use the coconut milk by Kara. After they are done, take them from the heat and proceed with the stew preparation.

Put some vegetable oil in a sufuria and heat it up. Add your red onion, the green onion, and the ginger garlic paste. To this add some salt and black pepper for seasoning. The house smelt so good at this point :). Let this saute until the onions are soft. Do not let the garlic burn as it will make the entire dish bitter.

I used spring onion with my red onion since the latter plays up the flavor of the former. This makes the dish even more aromatic and delicious.

Add your diced tomatoes together with the green bell pepper. Let this simmer on low heat until they soften. Then add your tomato paste and 1/4 cup of water and let this simmer for 3-5 minutes.

After they have simmered,  add the boiled njahi and mix them in. Mix your royco all spice mix into a paste with some water, and mix this in. Let this simmer for about 5-10 minutes. Add water to this 1/4 cup at a time until you attain the thickness you want. Adding too much at a time will make this unappetizingly dilute and light.

Add your finely chopped coriander, mix in then serve.

Nothing would bring you nearly as much delight as this njahi stew would. This is one of those dishes that you will always enjoy.

The taste of the onions comes through so well and the ginger compliments the bell pepper really well. The njahi picked the cumin and coconut milk flavor really well. This transformed this everyday Kenyan meal into a feast.

  1. I luv your blog..question after adding the coconut milk and water to the njahi while boiling,do u wait till they dry up..or can you just drain the excess when the are done?

      That will depend on your personal preferences. But personally, once they are done, I simply remove them from the heat and drain the excess water if any. If they over-stay, they may over cook and start to bomoka.But if very little water has remained, I wait for it to dry up. There is no one solid way of doing this, I just encourage you to follow your heart and instinct as you cook and do what you feel is right at the moment for you.

  2. I love njahi and yes it is a very unique bean. It can be hard to find if you live in a region where they are not grown. Very similar to black beans when cooked but oh so different. I cook mine almost the same way minus the Royco.

      Yes, it is very east African. And I guessed it was in the same family as black bean, though just by appearance. But maybe this recipe too can be used on black bean.

  3. Very happy to have come across your blog: simple recipes, easy to find ingredients. Can’t wait to give most of them a try! I am a super-lover of njahi, and I already have some in my freezer. How can I best alter this recipe with the pre-boiled njahi?

      Karibu sana Kui!Honored to have you as a reader. If you already have boiled njahi, you can still use/ follow the recipe as is from the point I start the actual cooking. However, If you feel you have to use the cumin, You can add a tablespoon together with your onions. Alternatively, you can add ground cumin spice as you add the royco. Ground cumin spice is available in any supermarket at about KES.120

      • I absolutely loved this recipe. The only thing I did different was simmer my pre-boiled njahi with coconut milk and ground cumin. Tho the cumin was a bit light. I’ll mix in one tablespoon next time. Thank you for what you’re doing.

  4. Kaluhi I really like your recipes ; well illustrated, step by step procedure and tasty too when implemented. The ingredients aren’t exotic either. Keep it up girl!

  9. Hey Kaluhi njahi gives alot of gas is there anything you do it to reduce that…

    • kaluhiskitchen

      April 29, 2017 at 12:19 pm

      For me it does not give me gas. I think it reacts do people differently. You are better off asking a nutritionist about that as they will offer a concrete solution to you. I do not have a nutrition background so I cannot answer that objectively.

  10. This recipe in particular has become my all time favourite way of enjoying njahi.😊 I have also made the Guinness marinated pork a household favourite. 😄Thank you for making cooking easy and exciting.😊
