Slow-cooked beef chuck roast seasoned with smoky, tangy spices and topped with quick pickled red onions, served in warm tortillas for a flavorful and easy taco meal.
Searing the beef before slow cooking adds depth of flavor but is optional. Keep the lid closed during cooking to maintain moisture. Adjust spice level by using fewer chipotle peppers or adding jalapeños. If sauce is too strong, balance with extra beef broth or a pinch of sugar. Shred beef when slightly cooled for easier handling.
