Brown the roast. Heat a skillet over medium-high heat. Add canola oil, and sear beef for 1-2 minutes per side until browned. (optional)
Place beef in the crock pot. Add broth, onion, garlic, Worcestershire sauce, and Italian seasoning.
Cover and cook on Low for 6-7 hours or High for 4 hours, until the beef is tender.
Use two forks to shred the beef into bite-sized pieces in the crock pot. Season with salt and pepper to taste. Add the noodles.
Cover and set to cook on High for 10-20 minutes until noodles are al dente. (Cooking time will vary by noodle type.)
For a thicker sauce, stir in the cream or cornstarch slurry. Let cook until thickened enough to coat a spoon.
Serve warm and enjoy your comforting beef and noodles.
