Start by seasoning your beef chuck roast with salt, pepper, and garlic powder, ensuring all sides are well-coated. Let it sit for about 15 minutes.

In an air fryer or skillet, sear the beef chuck roast on all sides for about 3-4 minutes until a rich brown crust forms.

In the slow cooker, combine beef broth, onion soup mix, and Worcestershire sauce. Stir until the onion soup mix is dissolved.

Place the seared beef chuck roast into the broth mixture, ensuring it is submerged. Cover and set to low heat for 8 hours.

About 15 minutes before beef is done, prepare egg noodles according to package instructions, keeping them slightly al dente.

Remove the beef from the slow cooker, shred it, and mix it back with the broth and cooked noodles. Serve with parsley and Parmesan.
