Beef Manhattan with Mashed Potatoes and Garlic Toast Recipe
Introduction
Beef Manhattan is a comforting and hearty dish featuring tender, slow-cooked chuck roast served over mashed potatoes and garlic toast. Its rich gravy and savory flavors make it a favorite for family dinners or cozy gatherings.

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 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 nice brown crust.
- Step 3: Transfer the seared roast to the bottom of a slow cooker.
- Step 4: Sprinkle the brown gravy mix and onion soup mix evenly over the roast. Pour in the red wine vinegar.
- Step 5: Cover and cook on low for 8-10 hours or on high for 5-6 hours, until the beef is very tender and easily shreds with a fork.
- Step 6: Remove the roast from the slow cooker and shred it using two forks. Return the shredded beef to the slow cooker, stir it into the gravy, and let it sit on warm for 10-15 minutes to absorb the flavors.
- Step 7: To serve, place a generous spoonful of mashed potatoes on a slice of garlic toast. Spoon the shredded beef and gravy over the top, garnish with fresh chopped parsley if desired, and enjoy.
Tips & Variations
- For deeper flavor, brown the roast in olive oil first as instructed, but also deglaze the pan with a little beef broth or wine to add to the slow cooker.
- Use homemade gravy and onion soup mix for a fresher taste, or try substituting balsamic vinegar for red wine vinegar to add a slightly sweeter note.
- Serve alongside steamed vegetables or a simple green salad to balance the richness of the dish.
Storage
Store any leftover beef Manhattan in an airtight container in the refrigerator for up to 3 days. Reheat gently in a covered skillet over medium-low heat or in the microwave until warmed through. The mashed potatoes and garlic toast are best served fresh but can be stored separately and reheated as needed.

FAQs
Can I use a different cut of beef for this recipe?
Yes, you can use other cuts suitable for slow cooking, such as brisket or round roast. Just ensure the cut is well-marbled and can become tender with slow cooking.
Is it necessary to use the slow cooker?
The slow cooker helps achieve tender, shreddable beef with minimal effort, but you can also braise the roast in a covered Dutch oven in the oven at 300°F for 3-4 hours until tender.

Ingredients
Beef and Seasoning
- 3 pound chuck roast (can use 3–4 lbs.)
- 1 tsp salt
- ½ tsp black pepper
- 2 Tbsp olive oil
Gravy and Flavorings
- 1 oz packet brown gravy mix
- 1 oz packet onion soup mix
- ¼ cup red wine vinegar
To Serve
- Mashed potatoes (homemade or store bought)
- Garlic toast (such as frozen Texas Toast)
- Fresh chopped parsley (for garnish, optional)
Instructions
- Prepare and Season the Roast: Pat the chuck roast dry with paper towels to remove excess moisture. Season all sides evenly with 1 teaspoon of salt and ½ teaspoon of black pepper to enhance the flavor of the beef.
- Sear the Roast: Heat 2 tablespoons of olive oil in a large skillet over medium-high heat. Once hot, sear the chuck roast for about 3-4 minutes on each side until it develops a rich brown crust, which helps lock in the juices and adds depth of flavor.
- Transfer to Slow Cooker: Place the seared roast at the bottom of the slow cooker, ensuring it sits flat for even cooking.
- Add Gravy Mixes and Vinegar: Sprinkle the 1 oz packet of brown gravy mix and 1 oz packet of onion soup mix evenly over the roast. Pour in ¼ cup of red wine vinegar to add a tangy depth to the sauce.
- Slow Cook the Beef: Cover the slow cooker and cook on low for 8-10 hours, or on high for 5-6 hours, until the beef becomes very tender and shreds easily with a fork.
- Shred and Reheat: Remove the roast from the slow cooker and shred the meat using two forks. Return the shredded beef to the slow cooker, stir it into the gravy thoroughly, and let it sit on warm for 10-15 minutes to absorb all the flavors.
- Assemble and Serve: To serve, place a generous scoop of mashed potatoes on a slice of garlic toast. Top with the shredded beef and rich gravy, then garnish with fresh chopped parsley if desired. Enjoy your comforting Beef Manhattan!
Notes
- Using a chuck roast of 3-4 pounds allows for enough tender meat and servings for about 6-8 people.
- If preferred, homemade brown gravy and onion soup mixes can be used instead of store-bought packets.
- Red wine vinegar adds a subtle acidity—apple cider vinegar could be an alternative if necessary.
- For extra richness, mashed potatoes can be made with butter and cream according to your preference.
- Make sure to sear the roast well to develop a deep flavor before slow cooking.
- Leftovers keep well refrigerated for up to 3 days and can be reheated gently on the stovetop or microwave.
