Mix seasoning blend: Combine the paprika, cumin, oregano, chili powder, onion powder, garlic powder, and coriander in a small bowl. Add 1/2 teaspoon of black pepper and 1 1/4 tablespoons of salt. To blend, thoroughly stir.
Place the steak on a spotless surface and season it. Two tablespoons of the spice mixture should be applied to the steak. Use your hands to rub the spices into the meat.
Cook the beef: 1 1/2 tablespoons of oil should be heated over medium-high heat in a Dutch oven or other big, heavy pot. Add the meat and brown it for about 8 minutes, turning it into batches if required. When browning meat in batches, add additional oil if necessary. Take out onto a platter.
Now that the saucepan is empty, lower the heat to medium and add the remaining 1 1/2 tablespoons of oil, then the onions, to begin sautéing the vegetables. Add a touch of salt and a pinch of pepper to the onions. Sauté for about 3 minutes, stirring now and then. Add the remaining seasoning mixture and the garlic. It takes approximately 30 seconds of continuous stirring before it begins to smell good. The tomato paste and diced chipotles are then added. For about 1-2 minutes, stir continuously until the paste turns caramelized.
Deglaze the pan with lime juice, then add the beef. Add the adobo sauce, stock, Picante sauce, and bay leaf after cooking, scraping up any browned bits from the bottom. After thoroughly combining, add the seared beef to the pot along with any accumulated juices.
Cover and cook: Simmer the mixture's ingredients. Low heat is applied while the pot is covered. Covered, simmer for 3–3 1/2 hours, or until the meat is fork-tender and crumbles. To get the greatest results, stir the beef once per hour.
Shred the beef by turning off the stove. Using tongs, remove the bay leaf and throw it away. Make two forks worth of beef shreds (you can also remove the beef to a cutting board, shred it, and return it to the pot.)
To warm, gently simmer: For around 10-15 minutes, turn the heat down to low and slowly simmer the meat.
Place the steak and cilantro in a serving dish to be served. Slices of lime are optional.
For tacos, top warmed corn tortillas with shredded cheese and add shreds of beef. Add chopped vegetables, Pico de Gallo, fresh cilantro, guacamole, or sour cream as toppings.
