Creating Slow Cooker Beef Manhattan is a straightforward process when you follow these simple steps:

1. Prepare the Beef: Trim any excess fat from the beef roast and cut it into large chunks if you prefer smaller servings.
2. Season the Beef: Sprinkle salt and pepper generously over the beef chunks on all sides.
3. Sear the Beef (optional): In a large skillet, heat a little oil over medium-high heat. Sear the beef on all sides until browned, then transfer to the slow cooker. This step adds extra flavor but can be skipped if you’re short on time.
4. Add the Vegetables: Chop the onion and garlic, then add them directly to the slow cooker.
5. Combine Ingredients: In a bowl, mix the beef broth, Worcestershire sauce, soy sauce, tomato paste, thyme, and paprika. Pour this mixture over the beef and vegetables in the slow cooker.
6. Cook: Cover and set the slow cooker to low for 6-8 hours or high for 3-4 hours. The beef should be tender and easily shredded when it’s done.
7. Thicken the Gravy (optional): If you prefer a thicker gravy, mix the flour with a little cold water to create a slurry. About 30 minutes before serving, stir this mixture into the slow cooker.
8. Shred the Beef: Once cooked, use two forks to shred the beef directly in the slow cooker. Mix it with the sauce until well combined.
9. Garnish: If desired, sprinkle fresh parsley on top for added color and flavor.
