Favourite Cuban Black Bean Soup

This is Cuban-style black bean soup the way it’s meant to be made: slow, patient, and built from almost nothing. Soaked dried beans, a gallon of water, a couple of onions, garlic, oregano, red pepper flakes, and parsley. Five hours of unattended simmering, then two more hours after the aromatics join.

The long cook is what builds the depth. The beans break down enough to thicken the broth into something between soup and porridge, while the aromatics infuse every spoonful. There’s no shortcut to this character. Pressure cookers get you tender beans, but they don’t get you this kind of flavor.

The prepared mustard is the curveball ingredient. A tablespoon stirred in during the second simmer adds a tang and depth you can’t quite identify but immediately miss if it’s left out. Cuban abuelas have been using this trick for generations.

Keep an eye on the pot during the seven hours total cook. The recipe warns about burning, and that’s the legitimate hazard with a long simmer over low heat. Stir occasionally and add water if the level drops too low.

Pro Tips

• Soak the beans overnight in plenty of water. Skipping the soak adds hours to the cook and leaves the skins tough.
• Use a heavy-bottomed pot, not a thin one. Thin pots scorch the beans at the bottom.
• Don’t add salt until the beans are tender. Salt added early can prevent the beans from softening properly.
• A splash of red wine vinegar or fresh lime juice stirred in at the end brightens the whole pot.

Variations

• Spoon over hot white rice and top with chopped raw onion (Cuban-style) for a complete meal.
• Add cubed cooked ham or chorizo in the last hour for a meatier non-vegan version.
• Stir in a tablespoon of olive oil and minced garlic at the very end (a sofrito finish) for a brighter, more layered flavor.
