Equipment

  • Heavy Buttom Dutch Oven or Large Pot

Ingredients

  • 3-4 lbs Trimmed Oxtail Fresh & Cleaned
  • 1/4 cup green sofrito
  • 8 ounces Goya tomato sauce
  • 1 medium red pepper sliced
  • 1 medium green pepper sliced
  • 1 medium yellow pepper sliced
  • 1 spanish onion sliced
  • 8 cloves garlic smashed
  • 4 tbsps oil divided
  • 3 tbsps brown sugar

To season the Oxtail

  • 1 packet Sazón or (2 teaspoons)
  • 1 teaspoon Maggi chicken bouillon powder (or 1 cube, crushed)
  • 2 teaspoons adobo
  • 1 teaspoon garlic powder
  • 2 teaspoons oregano
  • 1 teaspoon pepper
  • 2 teaspoons salt
  • 2 tablespoon oil
  • 2 teaspoons browning optional but helps with color

To Season the broth

  • 1 teaspoon adobo
  • 1 teaspoon oregano
  • 1 teaspoons salt or more to taste
  • 2 sprigs cilantro
  • 2 sprigs culantro if you can't find it, add more cilantro
  • 2 bay leaf

Instructions

Marinade the Oxtail

  • In a large bowl, combine the oxtails with the sazón, Maggi bouillon, adobo, garlic powder, oregano, browning (if using), pepper, and crushed garlic and 2 tablespoons of oil. Add half of the sliced peppers and onion. Toss until every piece is well coated, then cover and refrigerate overnight (or at least 4 hours).

Caramelize the brown sugar base: 

  • Heat a heavy-bottomed Dutch oven over medium heat. Add the oil, then the brown sugar. Stir continuously until the sugar melts and turns a deep mahogany color, about 2 minutes. Do not walk away — it goes from caramel to burnt very quickly.

Sear your oxtail

  • Remove the oxtails from the marinade, reserving the marinade juice and peppers. Working in batches to avoid crowding, sear the oxtails on all sides until deeply browned. (about 2-3 minutes on each side) Transfer to a plate as they finish.

Build the broth:

  • Pour the reserved marinade juice into the pot along with the sofrito and tomato sauce. Stir and let it bubble for 1-2 minutes. Stir in the broth seasonings: adobo, oregano, salt, and pepper to taste. Add 3-4 cups of water to the oxtail marinade bowl and pour the water into the pot.

Simmer low and slow

  • Return the oxtails to the pot ensuring they are fully submerged into the water. If needed, add more liquid. Add the cilantro, culantro, and bay leaf. Bring to a gentle simmer, then reduce heat to low, cover, and cook for 2-3 hours, stirring occasionally.

Finish

  • Stir in the remaining sliced peppers and onion. Simmer uncovered for another 10-15 minutes, until the peppers are tender-crisp and the gravy has thickened slightly. The oxtails are ready when a fork slides in easily and the meat pulls cleanly from the bone. Taste and adjust salt. Discard the bay leaf and let rest 5-10 minutes before serving over arroz con gandules, white rice, plantains, or yucca, with extra gravy spooned on top.

Notes

  • For best flavor, marinate the oxtails overnight.
  • Don't rush the brown sugar caramel — that deep mahogany color is what gives this stew its signature look and flavor.
  • Sear in batches; crowding the pan steams the meat instead of browning it.
  • This recipe tastes even better the next day. Make ahead when you can.
  • For a Cuban-style twist, add 1/2 cup dry red wine after searing.
  • For a Dominican-style spin, add the juice of a sour orange or fresh lime to the marinade.
  • Freezes well for up to 3 months.
