Step-by-Step Instructions

1. Season & Hard Sear the Beef (Chef Maillard Secret): Pat beef chunks completely dry. Rub all sides with cumin, smoked paprika, dried oregano, garlic powder, onion powder, coarse sea salt, and black pepper. Heat 2 tbsp beef tallow in an Instant Pot on SAUTÉ mode (or in a large Dutch oven over medium-high heat). Sear beef chunks for 4 to 5 minutes per side until deeply browned with a rich crust. Transfer seared beef to a plate.
2. Sauté Cuban Sofrito: Add sliced bell peppers and sliced onions to the hot rendered beef fat in the pot. Sauté for 4 to 5 minutes until vegetables soften and begin to caramelize around the edges. Stir in minced garlic and tomato paste; cook for 60 seconds until fragrant.
3. Deglaze & Combine: Pour in the beef bone broth, vinegar, olive brine, fire-roasted crushed tomatoes, sliced green olives, capers, and bay leaves. Use a wooden spatula to scrape up all the flavorful browned beef fond stuck to the bottom of the pot.
4. Pressure Cook or Slow Cook: Nestle the seared beef chunks and resting juices back into the bubbling sofrito sauce. Cover and lock the Instant Pot lid. Select PRESSURE COOK (HIGH) for 45 minutes. (Or transfer everything to a Slow Cooker and cook on LOW for 7 to 8 hours / HIGH for 4 hours).
5. Natural Release & Shred (Ropa Vieja Style): When cooking finishes, allow 15 minutes for natural pressure release, then release any remaining steam. Remove beef chunks to a large rimmed cutting board. Use two forks to shred the beef into long, tender strands. (The beef will pull apart effortlessly).
6. Simmer & Thicken Sauce: Return the shredded beef back into the pot with the peppers and sauce. Turn Instant Pot to SAUTÉ mode (or Dutch oven to medium heat) and simmer uncovered for 5 minutes, stirring occasionally, until the sauce thickens and coats every strand of shredded beef. Discard bay leaves.
7. Garnish & Serve: Stir in fresh chopped cilantro and squeeze fresh lime juice over the top. Serve steaming hot over cauliflower rice with crispy fried tostones, sliced avocado, and lime wedges!

Nutritional Breakdown (Per Serving)

Chef's Paleo Nutritional Science

Grass-fed flank steak is dense in bioavailable creatine, carnitine, zinc, and heme iron, supporting muscle protein synthesis and hemoglobin formation. Spanish Manzanilla olives and capers provide oleocanthal and quercetin polyphenols that downregulate inflammatory cyclooxygenase (COX) pathways.
