Pat the roast dry with paper towels so you get a great sear. Then coat both sides of the roast in oil and sprinkle evenly with salt and pepper.
1 (3-4 lb) chuck roast , 2 tablespoon olive oil, 2 teaspoon kosher salt, 1 teaspoon black pepper
Heat a large skillet over high heat (cast iron skillets are best). Once hot, sear the roast for 4-5 minutes per side, until it is golden brown. Once browned, transfer to a slow cooker.
Pour the beef broth into the hot skillet and simmer for 60 seconds, scraping up the brown bits from the bottom of the pan. Then pour the broth over the meat in the slow cooker.
1 cup beef broth
Cover with the lid and cook on low for 8-10 hours or high for 4-4.5 hours, or until it falls apart easily when prodded with tongs or forks. Low heat always produces more tender results!
While the meat is cooking, mix together the sauce ingredients in a bowl and set aside.
1 (18 oz) bottle bbq sauce, 1 cup blackberry preserves, 1 teaspoon kosher salt, 1 teaspoon smoked paprika, 1 teaspoon chipotle chili powder, ½ teaspoon black pepper
Once the meat is tender, use tongs to move it onto a cutting board and discard any cooking liquid from the slow cooker. Use two forks to gently remove and discard any large chunks of fat from the meat. Then use the forks to shred the roast into large-ish chunks (it will continue falling apart into smaller chunks in the next step).
Add the shredded meat back to the empty slow cooker, then pour the blackberry bbq sauce on top. Stir gently to combine. Allow to cook for about 15 additional minutes on low to allow the sauce to get warm and sticky, then serve hot.
