A close-up of a dish with three layers on a white plate with black speckles and a thin black rim. The bottom layer is a thick slice of golden brown cornbread with a slightly rough texture. The middle layer is a smooth, creamy white mashed potato spread evenly over the cornbread. The top layer consists of dark brown shredded beef in a glossy gravy, garnished with small green herb pieces. A fork held by a woman's hand is pressing into the beef, causing some gravy to drip over the cornbread. The background shows a white marbled surface with some leafy greens nearby.

Ingredients

3 pound chuck roast (can use 3-4 lbs.)
1 tsp. salt

½ tsp. black pepper
2 Tbsp. olive oil

1 oz. packet brown gravy mix
1 oz. packet onion soup mix

¼ cup red wine vinegar
Mashed potatoes (homemade or store bought)
Garlic toast (such as frozen Texas Toast)

Fresh chopped parsley (for garnish, optional)

Instructions

Step 1: Pat the chuck roast dry with paper towels. Season all sides evenly with salt and black pepper.
Step 2: Heat olive oil in a large skillet over medium-high heat. Sear the roast for 3-4 minutes on each side until it develops a browned crust.

Step 3: Place the seared roast in the bottom of your slow cooker.
Step 4: Sprinkle the brown gravy mix and onion soup mix evenly over the roast, then pour in the red wine vinegar.
Step 5: Cover the slow cooker and cook on low for 8-10 hours, or on high for 5-6 hours, until the beef is very tender and shreds easily with a fork.

Step 6: Remove the roast from the slow cooker and shred it with two forks. Return the shredded beef to the slow cooker, stir to combine with the gravy, and let it sit on warm for 10-15 minutes to absorb the flavors.
Step 7: To serve, place a generous scoop of mashed potatoes on a slice of garlic toast. Spoon the shredded beef and gravy over the top and garnish with fresh chopped parsley if desired. Enjoy!

Tips & Variations

For extra depth, add a splash of beef broth or a teaspoon of Worcestershire sauce to the slow cooker before cooking.

If you prefer a thicker gravy, stir a small amount of cornstarch mixed with water into the slow cooker 30 minutes before serving.
Substitute the red wine vinegar with apple cider vinegar for a milder tang.
Pair this dish with steamed green beans or a simple salad to add freshness and balance.

Storage

Store leftover shredded beef and gravy in an airtight container in the refrigerator for up to 3 days. Reheat gently on the stove or in the microwave until warmed through. Mashed potatoes and garlic toast are best enjoyed fresh but can be refrigerated separately and reheated with care.

How to Serve

A large white slow cooker filled with shredded dark brown meat in thick sauce, with some sauce splatters on the inner sides of the cooker. To the right, there is a small white bowl of creamy mashed potatoes and a bunch of fresh green parsley next to it. On the bottom right corner, a white plate with black speckles is partially visible, along with three shiny silver forks nearby. On the left side, a small white bowl with pink salt sits next to a black and white checkered cloth, and three slices of toasted bread with a golden brown crust rest on a wooden board. The whole scene is set on a white marbled background. photo taken with an iphone --ar 4:5 --v 7

FAQs

Can I make Beef Manhattan without a slow cooker?

Yes, you can cook the chuck roast in a covered Dutch oven at 325°F (165°C) for about 3-4 hours, or until tender. Follow the same seasoning and gravy steps, adjusting liquid if needed.

What can I use instead of garlic toast?

If you don’t have garlic toast, thick slices of toasted bread spread with butter and garlic powder work well. You can also try buttery dinner rolls or biscuits as a base for the beef and gravy.
