Season the Beef: Season the beef: Generously season the chuck roast with all of the kosher salt and black pepper, making sure to pat it in and cover all sides evenly.
2.5-3 pound boneless chuck roast, 2 teaspoons Morton kosher salt*, fresh cracked black pepper
Sear the Beef: Heat 2 tablespoons of avocado oil in a heavy large skillet or pot over medium-high heat. Sear the roast on all sides until browned, about 5-7 minutes per side. Use a splatter guard to prevent grease from getting everywhere.
2 Tablespoons avocado oil
Add Ingredients to the Slow Cooker: Add the sliced onions, minced garlic, beef broth, red wine, worcestershire sauce, brown sugar, onion powder, smoked paprika, thyme, rosemary, and bay leaf to the slow cooker. Nestle the seared roast in the middle.

Cook: Cover and cook on LOW for 8 hours or HIGH for 4-5 hours, until the beef is tender and shreds easily.
Shred the Beef: Remove the beef from the slow cooker and shred it with two forks. Strain the cooking liquid and reserve it for serving as au jus.
Assemble the Sandwiches: Pile the shredded beef onto toasted rolls, top with swiss cheese, and serve each sandwich with a side of au jus for dipping.
