How to Make r Slow Cooker Beef Manhattan

Step 1: Prep the Beef

Start by nestling your beef roast into the bottom of your slow cooker. No need to sear or season—this recipe is all about maximum flavor with minimum effort. The low and slow heat will work its magic, breaking down the beef until it’s irresistibly tender.

Step 2: Mix the Flavor Base

In a small bowl, whisk together the onion soup mix, beef broth, water, Worcestershire sauce, garlic powder, onion powder, and black pepper. That’s your powerhouse base! Pour this mixture evenly over the beef in the slow cooker. Trust me, this blend is going to create the most irresistible gravy.

Step 3: Slow Cook

Pop the lid on and let your slow cooker do all the heavy lifting. Cook on LOW for 6 hours (or HIGH for 3 to 4 hours) until the beef is fall-apart tender. The house will smell incredible while you go about your day.

Step 4: Make the Gravy

Carefully remove the beef and shred it into satisfying, chunky pieces using two forks. In a separate small bowl, stir together the cornstarch and water to make a slurry. Add that into the bubbling juices in the slow cooker, switch to HIGH, and let it cook about 5 minutes until the gravy is silky and thick.

Step 5: Assemble Beef Manhattan

To build each plate, lay a slice of bread on the plate, crown it with a big scoop of mashed potatoes, and pile on that beautiful shredded beef. Then, the finishing touch: drizzle your rich, glossy gravy all over, ensuring every nook is drenched in flavor.

Step 6: Serve & Enjoy

Sprinkle with fresh parsley if you like, and get ready to dig in. This is comfort food at its finest—every forkful is a warm hug, guaranteed to make your dinner table a happy place.

Garnishes

Nothing completes r Slow Cooker Beef Manhattan like a finishing sprinkle of fresh parsley, which adds a pop of color and livens up the whole dish. For a little extra indulgence, you could add a crack of black pepper or even a drizzle of garlic-infused oil right over the top.

Side Dishes

A crisp green salad or a medley of steamed veggies (think green beans, carrots, or peas) bring fresh contrast to the richness of your beef Manhattan. If you’re in the mood for something cozy, a skillet of buttery corn or glazed carrots hits just the right note, rounding out the meal beautifully.

Creative Ways to Present

Try swapping the standard bread for thick Texas toast, garlic bread, or even a fluffy biscuit for a Southern twist. Serve open-faced for a classic diner look, or stack it into a “Manhattan sandwich” for a fork-and-knife experience. For a fun party spread, make mini versions on slider rolls and arrange them on a platter with a gravy drizzle for dipping.

Make Ahead and Storage

Storing Leftovers

Got a busy week? No worries! Leftovers of r Slow Cooker Beef Manhattan keep wonderfully in the fridge for up to 4 days. Store the beef and gravy in an airtight container, and keep mashed potatoes and bread separate for best texture when reheating.

Freezing

Warm leftovers gently on the stovetop or in the microwave, adding a splash of broth or water if needed to loosen the gravy. To keep bread from getting soggy, toast slices fresh and reheat mashed potatoes separately for the same just-made taste and texture.

FAQs

Can I use a different cut of beef?

How do I thicken the gravy without cornstarch?

If cornstarch isn’t your thing, you can use arrowroot powder in the same way, or mash a little of the cooked potatoes into the gravy for natural thickening power.

What’s the best way to shred the beef?
