What Is Beef Manhattan?

Despite the name, Beef Manhattan isn’t actually from Manhattan, New York. It’s a beloved Midwestern comfort food classic, especially popular in Indiana and surrounding states.

Traditionally, it consists of:

• Thick slices of bread
• Roast beef or shredded beef
• Mashed potatoes
• Brown gravy poured generously over the entire plate

It’s often served in diners, family restaurants, and Sunday dinner tables because it’s simple, filling, and deeply satisfying.

This slow cooker version makes the classic even easier for busy home cooks.

Best Cut of Beef for This Recipe

Choosing the right cut makes all the difference.

Chuck Roast

Bottom Round Roast

Leaner but still flavorful, though slightly less rich.

Brisket

Excellent flavor, but often more expensive and requires careful cooking.

Pot Roast Cuts

Any well-marbled slow-cooking beef cut can work beautifully.

Chuck roast remains the easiest and most reliable option.

Garlic Herb Version

Mix roasted garlic and fresh herbs into the mashed potatoes for even more flavor.

Turkey Manhattan

Swap beef for slow-cooked turkey and turkey gravy for a holiday-inspired twist.
