How to Make Slow Cooker Beef Manhattan
Ingredients
- 3 pounds beef chuck roast or bottom round
- 1 large onion, thinly sliced
- 3 cloves garlic, minced
- 2 cups low sodium beef broth
- 1 tablespoon Worcestershire sauce
- 1 teaspoon dried thyme or 2 teaspoons fresh
- 1 bay leaf
- 1 teaspoon kosher salt, plus more to taste
- 1/2 teaspoon black pepper
- 2 tablespoons cornstarch mixed with 2 tablespoons cold water for slurry
- 8 slices hearty bread such as Texas toast, sourdough, or classic white
- 4 cups warm mashed potatoes, homemade or store bought
- 2 tablespoons butter, optional for toasting bread
Step by step
- Prep the beef: Pat the roast dry and season all over with salt and pepper. Browning is optional, but if you have 5 minutes, quickly sear it in a hot skillet with a little oil to deepen the flavor.
- Layer in the slow cooker: Add onions and garlic to the bottom. Place the roast on top. Pour in beef broth and Worcestershire. Add thyme and bay leaf.
- Cook: Cover and cook on Low for 8 to 9 hours or on High for about 4 to 5 hours, until the beef is very tender.
- Shred and thicken: Transfer the roast to a cutting board and shred with two forks. Skim excess fat from the cooking liquid, then turn the slow cooker to High. Stir in the cornstarch slurry and cook 10 to 15 minutes until the gravy is glossy and slightly thickened. Add the shredded beef back in and taste for salt and pepper.
- Toast and build: Lightly butter and toast your bread in a skillet or toaster. Place one slice on the plate, top with a scoop of beef, then add a generous spoon of mashed potatoes. Ladle more gravy over everything. Keep a napkin close.

What to Serve with Beef Manhattan
You really cannot go wrong with simple sides that balance the richness of the beef and gravy. I like a light green salad or steamed green beans for color and crunch. Buttered peas are a diner classic and they work perfectly here. If you are serving a crowd, add a second starch so folks can choose between mashed potatoes and something else.
- Veg sides: Green beans with lemon, roasted carrots, or a crisp salad with vinaigrette.
- Extra starch: Buttered egg noodles or garlic mashed cauliflower if you want something lighter.
- Something cheesy: This cozy side is a hit with kids and grownups alike: Slow Cooker Velveeta Broccoli Rice Casserole.
- Sweet finish: For dessert, let the slow cooker do one more job and make this super simple fruit treat: Slow Cooker Berry Crumble.

Variations
One of my favorite parts of this recipe is how forgiving it is. Once you get the base right, you can tweak without stress. Here are some ways to make it your own while keeping the spirit of the Delicious Easy Slow Cooker Beef Manhattan Sandwich Recipe.
Different cuts: Chuck roast gives you the most flavor and tenderness. Bottom round works too, though it is leaner, so make sure you do not overcook it to dryness. If you have leftover pot roast, that is perfect here.
Gravy boosts: Add a teaspoon of Dijon for subtle tang, a spoon of tomato paste for depth, or a splash of soy sauce for umami. Always taste and adjust salt at the end.
Bread choice: Texas toast gives that classic diner vibe. Sourdough adds a nice tang and holds gravy well. Whole wheat makes it feel a bit more wholesome without losing comfort.
Onion style: Use sweet onions if you want a milder gravy. Red onions will give a slightly deeper, richer flavor. Both work.
Mushroom lovers: Add 8 ounces sliced mushrooms in the last hour so they cook but do not disappear. It offers lovely texture and earthiness.
Extra creamy potatoes: Stir in a little cream cheese or sour cream to your mash if you like them ultra smooth.
If creamy comfort is your love language, you might also enjoy this cozy cousin in the slow cooker: Slow Cooker Beef Stroganoff Stew.
When I want to mix it up, I even swap the bread for a baked potato and spoon the beef and gravy over the top. It is a fun twist that still tastes like the Delicious Easy Slow Cooker Beef Manhattan Sandwich Recipe at heart.
Pro Tips
Brown if you can: A quick sear before slow cooking adds savory caramelized notes. Not required, but it is the small step that makes a big difference.
Use low sodium broth: It gives you control when seasoning at the end. Gravy concentrates flavors, so start with less salt and build up.
Thicken smart: Make sure your cornstarch slurry is smooth and cold when it hits the hot liquid so there are no lumps. Let the gravy simmer after adding the slurry to activate it.
Toast the bread: A light buttered toast keeps the sandwich from getting soggy and adds a nice crunch under all that gravy.
Hold warm for guests: Switch the slow cooker to Warm and the beef will stay perfect for up to 2 hours. Toast bread and heat potatoes right before serving.
Batch it: Double the recipe for a party, or freeze half the beef and gravy for a rainy day. Thaw overnight in the fridge and heat gently.

Common Questions
What cut of beef works best? Chuck roast is my top choice. It has enough marbling to turn tender and juicy after a long cook. Bottom round works, but do not skimp on the gravy.
Can I make the gravy without cornstarch? Yes. You can whisk 2 tablespoons flour into 2 tablespoons melted butter, then stir that into the hot cooking liquid and simmer until thickened.
Do I have to toast the bread? You do not have to, but I highly recommend it. Toasting keeps the bread sturdy and adds a nice buttery edge under the beef and potatoes.
How do I store leftovers? Refrigerate beef and gravy in a sealed container up to 4 days. Reheat gently on the stove or in the microwave. Keep the bread separate so it stays fresh.
Can I cook on high the whole time? Yes. Plan for about 4 to 5 hours on High. The meat should shred easily with two forks when it is ready.
