Cuban Black Beans

Frijoles Negros, Cuban Frijoles Negros

This cuban black beans recipe is the frijoles negros every Cuban kitchen cooks: dried black beans simmered until tender, then finished with a sofrito of onion, green pepper and garlic, cumin, oregano and a splash of vinegar, with a few beans mashed in to thicken the pot. One serving is about 250 g. Spooned over white rice, it is the everyday side that anchors the Cuban plate.

Black beans came to Cuba from the Americas and became the island's everyday bean, cooked the Spanish way with a sofrito base and served over rice. Frijoles negros is not a feast dish but the daily anchor of the Cuban plate — the pot that is always on the stove, eaten with rice, plantains or roast pork. Cooked with beans and rice together it becomes moros y cristianos; on its own, spooned over rice, it is simply frijoles negros.

Pairs well with: White rice, fried plantains and roast pork

Execution Methodology & Culinary Technique

Step-by-Step Cooking Guide

Active 1h 45m

Prep Stage: Soak the Beans and Dice the Sofrito

15 Mins + Overnight Soak

The night before, sort the beans, rinse them and cover with plenty of cold water to soak — they will nearly double in size. In the morning, drain and rinse them. Dice the onion and green pepper fine, chop the garlic, and measure out the cumin, oregano, vinegar and sugar so the sofrito comes together in minutes.

Maestro Tip: Dice the sofrito vegetables as fine as you can: they should melt into the beans, not sit in chunks.

  1. 1

    Rinse the Beans and Start the Pot

    10 Mins Bring to the boil at 100°C (212°F), then reduce

    Put the drained beans in a large pot with the water and the bay leaves. Bring to a hard boil over high heat, skim off any grey foam, then turn the heat down to a gentle simmer. Do not add salt yet — salt early makes the skins tough.

    Skim the foam in the first 10 minutes: it keeps the broth clean and the beans sweet.

    Done when: Water at a gentle simmer; foam skimmed; beans covered by at least 5 cm of water.

  2. 2

    Simmer the Beans Until Tender

    45 Mins Simmer at 85–95°C (185–203°F)

    Simmer the beans, covered loosely, for 45 minutes, until they are tender enough to squash easily between two fingers. Top up with a little hot water if the level drops below the beans. Leave the lid ajar so the pot does not boil over.

    Resist stirring hard: broken beans early on make the pot cloudy instead of velvety.

    Done when: Beans squash easily between two fingers; skins intact; broth dark.

  3. 3

    Make the Sofrito

    15 Mins Medium heat, about 175°C (350°F)

    While the beans simmer, heat the olive oil in a skillet over medium heat. Add the onion and green pepper and cook gently for 8 to 10 minutes until completely soft and translucent. Stir in the garlic, cumin and oregano and cook 1 minute more, until fragrant — do not let the garlic brown.

    Cook the sofrito low and slow: soft, sweet vegetables are the whole flavour of the dish.

    Done when: Vegetables soft and sweet; garlic fragrant, not browned.

  4. 4

    Combine and Finish Simmering

    25 Mins Simmer at 85–95°C (185–203°F)

    Ladle a cup of the hot bean liquid into the sofrito pan to loosen it, then scrape the whole sofrito into the bean pot. Add the salt, sugar and vinegar. Simmer gently for 25 minutes more so the flavours marry and the broth begins to thicken.

    Deglazing the sofrito pan with bean liquid gets every bit of flavour into the pot.

    Done when: Broth dark and fragrant; beans tender; sofrito melted into the pot.

  5. 5

    Mash, Season and Rest

    10 Mins Serve hot, about 70°C (158°F)

    Fish out the bay leaves. Scoop out about a cup of beans with their liquid, mash them to a rough paste and stir them back in — this is the moment the beans turn velvety. Taste and adjust salt and vinegar, rest 10 minutes, then serve over white rice.

    Mashing a cup of beans thickens the pot without any flour or cream — it is the Cuban trick.

    Done when: Thick, glossy beans that coat the spoon; balanced salt and acidity.

Finishing Touches & Plating

Rest the beans 10 minutes off the heat so the broth thickens and the flavours settle, then ladle them generously over white rice — the rice is not an afterthought, it is half the dish.

Nutrition values are estimated — calculated from USDA FoodData Central values for the listed ingredients.

Vitamins & minerals: Good source of iron, folate, magnesium and potassium from the black beans, with vitamin C from the green pepper. All nutrition values are estimated.

Protein and Fibre from Plants

About 15 g of protein and 11 g of fibre per serving from the beans alone, with iron and folate — a plant-based main that keeps you full for hours.

Beans and Rice Complete Each Other

Beans plus rice give you a complete set of amino acids, which is why this humble pairing has fed Cuba for generations.

Everyday Food That Loves Your Heart

Low in fat, high in fibre and rich in potassium and magnesium — the kind of everyday food that supports heart health as part of a balanced diet.

Food Pairings

What to Eat With

To optimize nutrient absorption and elevate the sensory depth, pair with these authentic accompaniments:

Sides

White Rice

The classic partner: the beans' dark, savoury broth soaks into the rice, and together they make a complete protein.

Fried Plantains (Tostones)

Crisp, salty tostones against the soft, velvety beans give the plate the crunch it needs.

Roast Pork (Lechon Asado)

For a feast, the beans sit beside slow-roasted pork with mojo — the rich meat and the earthy beans are made for each other.

Full Menus

Full Cuban Plate

Black beans over rice, tostones, lechon asado and a simple salad is the Cuban plate in full — the beans are its anchor.

Complete menu

Serve the beans over white rice with tostones and a green salad, and lechon asado for a full Cuban plate.

Digestive Guardrails

What NOT to Combine

To prevent digestive distress, sluggishness, or palate clash, avoid pairing the dish with these elements:

Very Salty Meats Alongside

The beans are already seasoned, so pairing them with very salty cured meats can push the meal's sodium far higher than needed. This is general information, not medical advice.

Eating Undercooked Beans

Beans must be simmered until fully tender; undercooked beans can cause stomach upset. Never eat beans that are still hard in the middle. This is general information, not medical advice.

General information only, not medical advice — consult a doctor for personal dietary decisions.

Who Should Eat It

Who Should Eat

  • General adultsA balanced, filling lunch for most adults — one serving over rice is a complete meal.
  • ChildrenSoft, mild and easy to eat; mash the beans a little more for young children and serve with rice.
  • ElderlySoft, easy to chew and rich in fibre and iron; serve the beans well mashed if chewing is difficult.
  • Pregnant womenRich in folate and iron, both important in pregnancy; ask your clinician about portion size.
  • Breastfeeding womenA nourishing, iron-rich dish; the beans can cause gas in some babies, so watch for it. Ask your clinician if unsure.
  • AthletesAbout 15 g of protein and 47 g of carbohydrate per serving — a solid plant-based recovery meal with rice.
  • Weight gainEasy to eat in large portions with rice and plantains to raise the calories.
  • Weight lossVery filling for its calories thanks to the fibre; keep the rice portion modest and skip the fried plantains.

Health Conditions — Adjust or Avoid

Conditions

  • DiabetesAbout 47 g of carbohydrate per serving, mostly slow-digesting bean starch — count it with the rice in your meal plan. Ask your clinician about portion size.
  • High blood pressureAbout 520 mg of sodium per serving; use less salt and rinse canned beans if you use them. Ask your clinician about portion size.
  • Kidney diseaseBeans are high in potassium and phosphorus; a smaller portion may be needed. Ask your clinician first.
  • GoutBeans add purines, so keep the portion modest and do not eat them every day. Ask your clinician about frequency.
  • Stomach issuesBeans can cause gas — soak them overnight, rinse well and eat slowly; the long simmer helps. Ask your clinician if symptoms persist.
  • Cardiovascular diseaseLow in fat, high in fibre and potassium — a heart-friendly choice as part of a balanced diet. Ask your clinician about portion size.
  • Fatty liverA good, low-fat choice; keep the rice portion moderate. Ask your clinician about portion size.
  • Food allergiesContains no common allergen — just beans, vegetables and oil. Ask your clinician if you have any rare allergy.
  • Special therapeutic dietsIf you follow a low-potassium or low-purine diet, beans need care — ask your clinician before eating them regularly.

If you have a medical condition, consult your doctor before changing your diet.
