Sprinkle the herb and garlic seasoning evenly over the chuck roast, rubbing it into all sides of the meat.
Heat the olive oil and butter in a large skillet over high heat until hot and melted. Add the seasoned roast and sear on all sides until deeply browned. This step adds rich flavor to the final dish.
Transfer the seared roast to the slow cooker. Add the chopped potatoes, baby carrots, onion, and minced garlic around the meat.
In a small bowl, whisk together the cornstarch and cold water until smooth. Pour the mixture into the slow cooker.
Add the red wine, beef broth, tomato paste, and tapioca pearls to the slow cooker. Stir gently to combine all the ingredients.
Cover and cook on low for 8 hours, or until the roast is fork-tender and the gravy has thickened. Once done, shred or slice the beef as desired and stir it into the gravy before serving.
Serve hot with plenty of gravy over the meat and vegetables.
Enjoy!
