Prepare the Oxtail: Clean oxtail thoroughly, pat dry, and season with salt, black pepper, paprika, cumin, and oregano. Marinate for at least 4 hours or overnight.
Sear the Meat: Heat oil in a heavy-bottomed pot. Sear oxtail pieces on all sides until golden brown. Remove and set aside.
Sauté Aromatics: In the same pot, cook onions, bell peppers, garlic, and hot peppers until fragrant.
Deglaze & Simmer: scraping the bottom to release browned bits. Return oxtail to the pot, add tomato sauce, beef broth, and bay leaves.
Slow Cook: Cover and simmer for 2.5 to 3 hours, stirring occasionally, until the meat is tender. For faster cooking, use a pressure cooker (45-60 minutes).
Thicken the Sauce: Let the sauce reduce naturally or mash softened vegetables for a thicker consistency.
Serve & Enjoy: Garnish with fresh herbs and serve with white rice, fried plantains, or crusty bread.
