• 1 tablespoon unsalted butter
• 1/2 cup panela, grated (or dark brown sugar)
• 1 large yellow onion, finely chopped
• 1 red bell pepper, finely chopped
• 1 (14.5 oz) can diced tomatoes, undrained
• 1/2 cup dry red wine
• 2 cups beef broth, low sodium

Directions

1. Marinate the Beef Overnight In a large non-reactive bowl or resealable plastic bag, combine the minced garlic, 1/2 cup red wine, 1/4 cup cola, Worcestershire sauce, 1 teaspoon cumin, 1 teaspoon black pepper, bay leaf, and 1 teaspoon salt. Using a sharp knife, pierce the beef roast all over with shallow cuts (about 1/2 inch deep) to help the marinade penetrate. Place the roast in the marinade, ensuring it's well coated. Cover and refrigerate overnight, or for at least 8 hours, up to 24 hours. Before searing, remove the beef from the fridge and let it come to room temperature for about 30-60 minutes.
2. Brown Sugar Caramel & Sear In a large, heavy-bottomed pot or Dutch oven (that has a lid), heat 1/4 cup neutral cooking oil over medium-high heat. Add the grated panela (or brown sugar) and cook, stirring occasionally, until it melts and turns into a deep amber caramel. This should take about 3-5 minutes. Be careful not to let it burn – it should be a rich brown, not black.
3. Carefully remove the beef from the marinade (reserve the marinade!) and pat it very dry with paper towels. Place the roast in the hot caramel and sear on all sides until nicely browned, about 3-4 minutes per side. This step builds incredible flavor and color for your roast chuck roast or eye of round. Don't worry if you get a little smoke; just ensure good ventilation. Once browned, remove the beef from the pot and set aside.
4. Build the Braising Sauce Reduce the heat to medium. Add the remaining 2 tablespoons of neutral oil and 1 tablespoon of butter to the pot. Add the chopped onion and bell pepper, sautéing until softened, about 5-7 minutes. Stir in the canned diced tomatoes (undrained), the remaining 1/2 teaspoon cumin, 1/2 teaspoon black pepper, and the second bay leaf. Cook for 2-3 minutes, stirring constantly.
5. Pour in the 1/2 cup dry red wine and the reserved marinade. Scrape up any caramelized bits from the bottom of the pot with a wooden spoon – these are flavor gold! Bring to a simmer, then add the beef broth and the remaining 1/2 cup cola. Bring the sauce back to a gentle simmer.
6. Slow Braise Until Tender Return the seared beef roast to the pot, ensuring it's mostly submerged in the sauce. The sauce should come about two-thirds of the way up the sides of the roast. If not, add a little more beef broth or water. Cover the pot partially with the lid, allowing a small gap for steam to escape. You can either keep it on the stovetop over very low heat (just a bare simmer) or transfer the pot to a preheated oven at 300°F (150°C).
7. Braise for 3 to 4 hours, flipping the roast every hour or so, until the beef is incredibly tender and easily pierced with a fork. The internal temperature should reach around 195-205°F (90-96°C) for optimal tenderness.
8. Rest & Slice the Roast Carefully remove the cooked roast from the pot and place it on a cutting board. Tent it loosely with foil and let it rest for at least 15-20 minutes. This resting period is crucial for the juices to redistribute, ensuring a moist and tender slice. Once rested, slice the beef against the grain into 1/2-inch thick slices.
9. Blend, Reduce & Finish the Sauce While the beef rests, remove the bay leaves from the braising liquid. Using an immersion blender directly in the pot, or carefully transferring the sauce to a regular blender, blend the braising liquid and vegetables until smooth. For a chunkier sauce, blend only part of it.
10. Return the blended sauce to the stovetop over medium heat. Bring it to a simmer and reduce, stirring occasionally, until it reaches a glossy, spoon-coating consistency. This reduction concentrates the flavors and creates that signature dark, rich look. Taste and adjust seasoning: add salt and pepper as needed. If the sauce is too sweet, a splash of red wine vinegar or a little more dry red wine can help balance it out.
11. Sauce & Serve Gently return the sliced beef to the finished sauce, ensuring each piece is coated. Allow it to warm through for 5-10 minutes over low heat. Serve the Posta Cartagenera with plenty of the luscious sauce spooned generously over the top and on the side.
