In a bowl, mix together diced onion, minced garlic, beef broth, cream of mushroom soup, Worcestershire sauce, Italian seasoning, garlic powder, onion powder, salt, and pepper.
Pour this mixture over the roast in the slow cooker. Add bay leaves.
Cover and cook on low for 8-10 hours or on high for 5-6 hours, until the beef is tender and easily shreds.
About 30 minutes before serving, remove the bay leaves and shred the beef in the slow cooker using two forks.
Cook the egg noodles separately according to package instructions to al dente.
Drain the noodles and add them to the slow cooker with the shredded beef. Stir gently to combine.
Serve warm, garnish with fresh parsley, if desired. Enjoy!
Notes
Thickening: If you prefer a thicker gravy, you can make a slurry with 2 tablespoons of cornstarch and 1/4 cup cold water. Stir this into the beef mixture about 30 minutes before serving.Refrigerate any leftovers in an airtight container for up to 5-6 days.
