Key Ingredients (and Smart Swaps)

Beef Roast (Chuck or Bottom Round)

For the best Beef In Slow Cooker texture, choose a well‑marbled chuck roast (3–4 lb). Bottom round works and slices neatly; chuck shreds luxuriously.

Aromatics & Seasoning

Onion, garlic, Worcestershire, and thyme layer savory depth. A touch of tomato paste boosts body without tasting tomatoey.

Beef Stock

Use low‑sodium beef stock to avoid an overly salty gravy; you’ll reduce and season to taste later.

Slurry for Gravy

A simple cornstarch (or flour) slurry yields a silky, diner‑style gravy right in the crock insert—no extra pot needed.

Toast & Mashed Potatoes

Classic Beef Manhattan stacks sliced roast (or shreds) over thick toast, with mashed potatoes and ladles of gravy all over. Garlic bread is a great twist.

How to Make 8‑Hr Slow Cooker Beef Manhattan

Season & Sear (Optional but Worth It): Pat a 3–4 lb chuck roast dry; season with 2 tsp kosher salt and 1 tsp black pepper. Sear in a hot skillet with 1–2 tbsp oil until deeply browned on both sides (3–4 minutes per side). Transfer to the crock pot.
Build the Base: Add 1 large sliced onion, 3 minced garlic cloves, 2 cups low‑sodium beef stock, 1 tbsp Worcestershire sauce, 1 tbsp tomato paste, 1 tsp dried thyme (or a few sprigs fresh), and 1 bay leaf.
Set & Forget: Cover and cook on Low for 8 hours (or High for 5–6) until the roast is fork‑tender. This is peak Beef Roast In Crock Pot comfort.
Make the Gravy: Remove roast to a board (tent with foil). Whisk 2 tbsp cornstarch with 2 tbsp water; stir into the crock juices. Turn to High and cook 10–15 minutes until glossy and lightly thickened. Adjust salt, pepper, and a tiny splash of Worcestershire to taste.
Slice or Shred: Slice for a classic presentation or shred for piled‑high plates. Both are stellar “Recipes With A Roast” outcomes.
Build the Plate: Place toasted thick bread on the plate, top with beef, add a scoop of mashed potatoes, and ladle gravy over everything. Green peas or buttered corn on the side keep the diner spirit alive.

Tips & Tricks for Diner‑Style Results

Choose chuck for shredding, round for slicing: Both are excellent; choose the texture you prefer.
Sear for depth: Browning adds roasted flavors to the gravy with minimal effort.
Salt at the end: Stocks vary; finish seasoning after the gravy thickens.
Make‑ahead magic: Chill overnight; reheat gently—flavor gets even better.

Serving Suggestions & Variations

Keep it classic with white or sourdough toast and buttery mash. Or swap in garlic toast, Texas toast, or toasted brioche for a luxe finish. For vegetables, think buttered peas, green beans, glazed carrots, or a crisp diner salad. Turn leftovers into open‑face sandwiches, beef poutine, or a baked potato topper—prime candidates for Slow Cooker Favorites batch cooking.

Storage, Make‑Ahead & Freezing

Refrigerate: Up to 4 days in airtight containers. Reheat gently with a splash of stock to loosen gravy. Freeze: Up to 3 months (store beef and gravy together; potatoes separately). Thaw overnight for best texture.
