This Beef Manhattan recipe brings slow-cooked roast beef, savory onion gravy, and creamy mashed potatoes together for a classic American dinner. Easy to prep and perfect for weeknights or family gatherings.
Season both sides of the chuck roast with salt and pepper. Heat olive oil in a large skillet over medium-high heat. Sear beef on each side for 2-3 minutes. Then place in the crockpot.
In a bowl, whisk together beef broth, thyme, garlic, onion soup, ketchup, and Worcestershire sauce. Pour over the beef.
Cover and cook on low for 8-9 hours.
Remove the beef from the crockpot and shred using two forks. In a small bowl, whisk ⅓ cup of the gravy with cornstarch until smooth. Return the slurry to the crock pot and whisk to combine. Add the shredded beef back in, toss to coat, and cook for 10 minutes or until the gravy thickens.
Serve over garlic toast topped with mashed potatoes and enjoy!
Notes
Sear the beef before slow cooking to lock in all the flavor.
Whisk cornstarch with gravy before adding to avoid lumps.
Check the beef for tenderness at 8 hours and cook longer if needed.
Serve over mashed potatoes or bread to soak up all the rich gravy.
