How to Make It

Prep your roast. Pat it dry, season with salt and pepper, and give it a quick sear in a hot skillet. (This locks in flavor and makes you feel like a pro.)
Layer it in the slow cooker. Place onions and garlic at the bottom, set the roast on top, then pour over the beef broth and Worcestershire sauce.
Set it and forget it. Cook on low for 8 hours or until the beef is fall-apart tender.
Make the gravy. Remove the roast, whisk cornstarch into the cooking liquid, and simmer until thickened.
Assemble your Beef Manhattan. On a plate, lay down a slice of bread, pile on mashed potatoes, top with shredded beef, and smother in gravy.
Serve warm and watch it disappear.
