Slow Cooker Beef Manhattan
Tender, slow-cooked beef chuck smothered in rich, savory gravy and served over toast or mashed potatoes — this Slow Cooker Beef Manhattan is the ultimate set-it-and-forget-it comfort food. The beef cooks low and slow for 8 hours, becoming melt-in-your-mouth tender while the gravy develops deep, complex flavors from seared fond, Worcestershire sauce, tomato paste, and optional red wine.
Equipment
- 6-quart slow cooker Programmable model recommended to auto-switch to warm
- Large skillet Cast iron preferred for best searing results
- Sharp knife
- Cutting board
- Measuring cups and spoons
- Wooden spoon
- Fat separator (optional) Useful for removing excess fat from gravy before serving
Ingredients
For the Beef
- 3 lbs beef chuck roast 1.36kg, cut into 2-inch chunks
- 2 tbsp vegetable oil 30ml
- 1 large onion diced
- 4 cloves garlic minced
For the Gravy
- 3 cups beef broth 720ml; or use Better Than Bouillon beef base dissolved in water for deeper flavor
- 1 cup red wine 240ml, optional; substitute with additional beef broth if preferred
- 3 tbsp Worcestershire sauce 45ml
- 2 tbsp tomato paste 30g
- 2 tsp dried thyme or substitute rosemary
- 2 bay leaves removed before serving
- 1 tsp black pepper
- 1 tsp salt plus more to taste
For Thickening
- 3 tbsp cornstarch plus more if needed
- 3 tbsp water cold, for making cornstarch slurry
For Garnish & Serving
- fresh parsley chopped, for garnish
- thick sliced white bread toasted, for traditional open-faced serving
- mashed potatoes optional alternative to toast for serving
Instructions
- Pat beef chunks completely dry with paper towels, then season all sides generously with salt and pepper. Let the meat rest at room temperature for 15 minutes while you prep the remaining ingredients.
- Heat vegetable oil in a large skillet over medium-high heat until shimmering. Working in batches, sear beef chunks 2–3 minutes per side until deeply browned, then transfer to the slow cooker.
- In the same skillet, cook the diced onion for 4–5 minutes until softened, then add garlic and tomato paste and cook 1 minute more. Transfer the onion mixture to the slow cooker.
- Pour beef broth and red wine into the slow cooker, then add Worcestershire sauce, thyme, and bay leaves. Stir to combine, ensuring the beef is mostly submerged.
- Cover and cook on LOW for 8 hours (or HIGH for 4–5 hours) until the beef is fork-tender. Avoid lifting the lid during cooking.
- Remove and discard the bay leaves, then whisk together the cornstarch and cold water and stir into the slow cooker. Cook on HIGH for 15–20 minutes until the gravy reaches your desired consistency.
- Use two forks to shred the beef directly in the slow cooker and stir to coat with gravy. Taste, adjust seasoning, and serve over toast or mashed potatoes garnished with fresh parsley.
Notes
- Best cut of beef: Chuck roast is ideal due to its marbling — brisket, bottom round, or rump roast also work well. Avoid lean cuts like sirloin or tenderloin as they'll dry out.
- Don't skip searing: Browning the beef creates a flavorful crust via the Maillard reaction and develops fond in the pan that adds serious depth to the gravy.
- Deglaze for extra flavor: After searing, add a splash of wine or broth to the skillet and scrape up all the browned bits before adding the mixture to the slow cooker.
- No wine? Substitute an equal amount of beef broth plus 1 tablespoon of balsamic or red wine vinegar to mimic the acidity.
- Gravy too thin? Add another tablespoon of cornstarch mixed with a tablespoon of cold water and cook on HIGH an additional 10 minutes.
- Slow cooker runs hot? Check the beef at 6–7 hours to avoid overcooking — it should be fork-tender but not falling apart before shredding.
- Storage: Refrigerate in an airtight container for up to 4 days. Freeze in portions for up to 3 months; thaw overnight in the refrigerator before reheating.
- Reheating: Warm on the stovetop over medium-low heat or microwave for 2–3 minutes, adding a splash of beef broth if the gravy has thickened.
- Make it your own: Add 8 oz sliced cremini mushrooms with the onions, stir in red pepper flakes for heat, or bulk it up with diced carrots and celery.
- Serving tip: Let the finished dish rest 10 minutes before serving for the best texture, and skim excess fat with a fat separator if desired.
