Creating the delicious Slow Cooker Beef and Noodles is a breeze if you follow these straightforward steps:

1. Prepare the Beef: Trim excess fat from the chuck roast and cut into large chunks for even cooking.
2. Add Vegetables: Place chopped onion, sliced carrots, and chopped celery in the bottom of the slow cooker.
3. Mix Marinade: In a bowl, combine minced garlic, beef broth, soy sauce, Worcestershire sauce, dried thyme, salt, and black pepper. Stir well.
4. Add Beef: Place the beef chunks on top of the vegetables in the slow cooker.
5. Pour Broth Mixture: Pour the prepared broth mixture over the beef.
6. Set the Slow Cooker: Cover and cook on low for 6 to 8 hours or on high for 3 to 4 hours, until the beef is fork-tender.
7. Cook the Noodles: About 30 minutes before serving, stir in the egg noodles. If the mixture is too thin, you can mix cornstarch with a bit of cold water and add to the slow cooker to thicken the broth.
8. Shred the Beef: Once the cooking time is complete, remove the beef from the slow cooker and shred it with two forks. Return the shredded beef to the cooker.
9. Mix and Serve: Stir everything together and let it cook for an additional 5 to 10 minutes to meld the flavors.
10. Garnish: Serve hot, garnished with fresh parsley for a pop of color and freshness.

These steps will ensure that your Slow Cooker Beef and Noodles turns out amazing every time!
