This delicious but easy recipe is a keeper. I did substitute Worcestershire sauce for the red wine vinegar. I also worried that there would not be enough gravy so threw in a can of beef broth. Turned out great! Giving it ***** 5 stars!

I’ve been sharing slow cooker recipes for more than a decade, and Beef Manhattan is one of those classic comfort dishes that feels a bit elegant while remaining effortless. It’s essentially slow-cooked roast beef in a savory gravy with a bright note of vinegar. The meat becomes fork-tender and soaks up the sauce, which makes it perfect over mashed potatoes and garlic toast. Below is a clear, step-by-step version of the recipe along with tips, variations, and serving ideas so you can get great results every time.

Key Ingredients
Beef: A 3-pound chuck roast (3–4 lbs. is fine) works best. The marbling turns the meat tender and shreddable after slow cooking.
Seasonings and Mixes: A packet of brown gravy mix and a packet of onion soup mix create the gravy base. Season simply with salt and black pepper.
Red Wine Vinegar: A quarter cup of red wine vinegar adds brightness and a distinctive tang that lifts the flavor of the gravy.
To Serve: Traditionally served over mashed potatoes and garlic toast (frozen Texas Toast works great). Fresh chopped parsley is optional for garnish.
How to Make Beef Manhattan
- Sear the seasoned chuck roast briefly on all sides to develop color and deepen the flavor.
- Place the roast in the slow cooker and top with brown gravy mix, onion soup mix, and red wine vinegar. Cover and cook low and slow until very tender.
- Shred the beef, return it to the gravy, and let it rest in the warm slow cooker so it soaks up the sauce. Serve over mashed potatoes and garlic toast.



Tips & Variations
Searing: Searing the roast first takes only a few minutes but adds a lot of flavor. If you’re short on time, you can skip it; the slow cooker will still produce tender beef.
Extra Vegetables: Add sliced onions or mushrooms under and around the roast to deepen the sauce and add texture. They will melt into the gravy and add sweetness.
Different Cuts: Chuck roast is ideal, but brisket or rump roast are suitable alternatives if that’s what you have on hand.
Vinegar Swap: If you prefer, you can substitute Worcestershire sauce for the red wine vinegar for a richer, less tangy profile.

Other Ways to Serve Beef Manhattan
If you want an alternative to mashed potatoes and garlic bread, here are several delicious options:
Buttered Noodles: Serve the shredded beef and gravy over buttered egg noodles for a homey plated meal.
Steamed Rice: Spoon the beef over steamed white or brown rice for a simple, comforting contrast to the rich meat.
Sandwich or Hoagie: Place the shredded beef on biscuits or in a hoagie roll with provolone for a hearty sandwich. Add pickles or sautéed peppers if you like.
Vegetable Sides: Brighten the plate with steamed green beans, a crisp green salad, or roasted seasonal vegetables.

Tips for When Your Slow Cooker Beef Stays Tough
If the roast is still firm at the end of the suggested cook time, it simply needs more time. Replace the lid and continue cooking for another hour or two on low. Keep the lid on during cooking—every time you lift it the slow cooker loses heat and the total cook time must be extended.

Beef Manhattan Recipe
Equipment
-
Slow cooker (6 quart or larger)
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
For serving:
- Mashed potatoes, homemade or store-bought
- Garlic toast (such as frozen Texas Toast)
- Fresh chopped parsley, for garnish (optional)
Instructions
-
Pat the chuck roast dry with paper towels and season generously on all sides with the salt and black pepper.
-
Heat the olive oil in a large skillet over medium-high heat. Sear the roast for 3–4 minutes per side until a deep brown crust forms. Searing adds flavor but can be skipped if you’re short on time.
-
Transfer the roast to the slow cooker. Sprinkle the brown gravy mix and the onion soup mix over the top, then pour the red wine vinegar around the roast.
-
Cover and cook on low for 8–10 hours, or on high for 5–6 hours, until the beef is very tender and pulls apart easily with a fork.
-
Remove the roast to a cutting board and shred it with two forks. Return the shredded beef to the slow cooker, stir it into the gravy, and let it sit on the warm setting for 10–15 minutes so the meat absorbs the sauce.
-
To serve, place a scoop of mashed potatoes on a slice of garlic toast, spoon the shredded beef and plenty of gravy over the top, and garnish with chopped parsley if desired. Enjoy warm.

More Meat and Gravy Ideas
If you enjoy this kind of hearty, saucy roast, try adapting the technique to other dishes: make hot roast beef sandwiches with the same shredded beef and gravy, use the gravy with chicken instead of beef, or try a pot roast cooked the same slow way for a different flavor profile. You can also turn leftovers into sandwiches, serve over rice or noodles, or pair the beef with roasted vegetables for a balanced plate.
