About This Recipe

You will never go to a Costa Rican home where there are no beans on the stove or in the fridge. Many Costa Rican moms even batch cook black beans for their kids when they leave for the week for work or college. 

We eat white rice and black beans with almost every meal- even breakfast! Luckily, long gone are the days of soaking beans overnight and then simmering them on the stove all day. With a slow cooker, you can have beans ready with almost zero prep!

This Costa Rican black bean recipe combines all the flavor of the traditional recipe with the ease of slow cooking. Put them in the pot overnight and wake up to delicious black beans.

Recipe – Costa Rican Slow Cooker Black Beans

Ingredients:

  • 1 lb black beans
  • 2 tsp salt (I prefer sea salt)
  • 1/2 red pepper, cut into 3 pieces
  • handful roughly chopped cilantro
  • 2 garlic cloves, whole
  • 1/2 white or yellow onion, peeled and roughly chopped
  • 1 celery stalk, chopped into 3 pieces
  • 1 carrot, chopped into 3-4 chunks
  • Salsa Lizano (optional, for garnish)


Instructions:

Rinse the beans and place them in the crock pot. 

Rinse and chop your veggies, then add them on top of the beans.

Add salt and enough water to cover the beans, plus about another 2 inches. Since the beans do absorb quite a bit of water when cooking, you want to have some extra so the beans don’t scald and stick to the bottom of your pot.  

Cook the beans in the slow cooker on low for 8-10 hours, or cook on high for 4-5 hours. The cooking time varies depending on your pot and electrical current.

I add the salt at the beginning of the recipe, but many people prefer to add them in the last 30 minutes of cooking because they say the salt makes the beans harden. I don’t think it does, but to each his own.

When you are ready to serve, just remove the large vegetable chunks and serve separately. Or keep them in! 

Black beans are often served with Salsa Lizano, but if you add the Lizano to the entire pot of beans, they can go bitter fast. It is better to put the Lizano on individual portions, or on the beans that you are sure you will serve.   Store in an airtight container in the refrigerator for up to 10 days.

Substitutions

You can really use any type of beans with this recipe- we will sometimes get tired of black beans and then use a red bean like a dark red kidney. When we make white beans with pork, we cook the beans in this style as well. 

You can also cook your garbanzo beans in this style- really all of the Costa Rican beans are cooked this way and then different ingredients are added depending on what recipe we are making.

Variations

This recipe works well in the pressure cooker, and we have an Instant Pot version. Some people simmer the beans for several hours on the stove top, but for that method, I recommend soaking the beans overnight first.

You can add bay leaves to the recipe to add some flavor, and you can get away with using Worcestershire sauce in place of Lizano if you had to- but Lizano is better.

Some people cook their black beans in chicken broth, but that is not traditional to Costa Rica at all. Neither is adding chili powder or lime juice- those are Mexican variations.

FAQ

What is the best way to reheat the beans? – I generally reheat them on the stove by putting them in a saucepan and leaving them on medium-low until the just bubble. 

Can I make these in a pressure cooker instead? Absolutely- just cook them for about 20 minutes after the pressure rises, and use a slow release.

Can I soak the beans to make this recipe? – You can, but you would cut the cooking time in half.
