Prepare the Beef: In a large mixing bowl, combine your beef stew meat with Worcestershire sauce, salt, black pepper, dried Italian seasoning, and smoked paprika. Toss the ingredients thoroughly until the beef is evenly coated. Allow to sit for about 10 minutes.

Set Up the Slow Cooker: Arrange the halved baby potatoes at the bottom. Drizzle half of the melted butter and olive oil over them. Sprinkle the minced garlic on top.

Layer the Beef: Place the seasoned beef cubes on top of the potatoes. Drizzle the remaining melted butter and olive oil over the beef.

Cook the Dish: Cover and cook on low for 6-7 hours or high for 3-4 hours until the beef is fork-tender and the potatoes are fully cooked.

Serve and Garnish: Stir the mixture gently and transfer to a serving dish. Garnish with freshly chopped parsley.
