This traditional Venezuelan beef roast is braised over low heat and is made with a marinade of papelón (unrefined brown sugar), garlic, Worcestershire sauce, cumin, rosemary, onion, tomato, bell pepper, sweet pepper, tomato paste, salt, and black pepper.
Remove any skin or excess fat from the eye of round beef roast. Rinse the meat under running water, then pat dry.
Peel the garlic and crush it. In a small mixing bowl, mix the crushed garlic, salt, Worcestershire sauce, cumin, black pepper and rosemary. Rub the piece of meat with the seasoning you just made and set it aside to rest while you prepare the other ingredients.
Peel the onions, cut them in half, and grate them on the coarse side of the cheese grater.
Cut the tomatoes in half, without peeling them, remove the seeds, and grate them the same way as the onions.
Wash the small, sweet chili peppers and the red bell pepper. Cut off the stems and remove the veins and seeds. Then finely chop them with a knife. If you wish, and find it more convenient, you can grate them as well.
Place the roast in a long, narrow container, preferably glass or ceramic. Cover the roast with the grated vegetables: onion, tomato, bell pepper and sweet chili pepper. Add the tomato paste. Rub the roast with the grated vegetables, making sure they are well mixed. Cover the container and let the beef marinate overnight in the refrigerator.
The next morning, place a large frying pan over high heat. When it is hot, spread the grated papelón or brown sugar over the surface of the pan. The sugar will melt and eventually turn dark brown. There will be some smoke, so don't worry. Add half of the oil.
Remove the roast from the bowl and wipe off the excess marinade. Save all the marinade for later to prepare the sauce for the roast. Place the roast on the hot pan, making sure the burnt sugar sticks to the roast. Cook it for about five minutes on each side over high heat. The entire surface of the roast will turn very dark brown. Add the oil little by little as needed. Once fully seared, turn off the pan and transfer the roast to an instant pot or crockpot.
Pour the saved marinade mixture and three cups of water in crockpot or instant pot, add the seared roast. Cook on low heat in the crockpot for approximately four hours. If you notice that there is not enough liquid, you can add an additional cup of water.
After four hours, remove the roast from the pot and let it rest for 10-15 minutes. Then place it on a cutting board. Cut it into slices. Pour all the sauce/leftover cooking liquid from the pot into a blender and blend on until you have a creamy, smooth mixture.
Serve the Asado Negro roast slices with mashed potatoes and with plenty of sauce.
Notes
Sometimes when I'm short on time, I don't grate the vegetables; I blend them with the water and marinate the roast in this sauce.
A common variation of the roast is to substitute one cup of water with one cup of Malta drink.
