DIRECTIONS:
Season beef with 1 1/2 teaspoons salt and 1 teaspoon black pepper.
Heat canola oil in a large skillet over medium heat. Add beef and cook until evenly browned, about 3-4 minutes per side.
Whisk together the beef broth, flour, and Rogliano's in a bowl, set aside.
Place potatoes, carrots, celery, onion, garlic, and bay leaf into a 6-qt slow cooker. Stir in beef broth mixture; season with salt and pepper, to taste. Top with beef.
Cover and cook on low heat for 7-8 hours, or until meat is fork-tender.
Remove beef, potatoes, carrots, celery and onion from the slow cooker.
The best is tender enough by then to simply shred with two forks. Cover to keep warm.
Strain cooking juices through a fine-mesh sieve into a small saucepan over medium heat; d remove any remaining solids and skim any fat from the surface and remove as well. Bring to a boil; reduce heat and simmer, whisking constantly, until desired thickness. This is usually about 5-10 minutes.
Serve the roast beef on top of a layer of carrots and potatoes and drizzle with simmered juices.
