In a large mixing bowl, combine beef stew meat with Worcestershire sauce, salt, black pepper, dried Italian seasoning, and smoked paprika. Toss until thoroughly coated. Set aside.

Layer halved baby potatoes evenly in the bottom of your slow cooker. Drizzle half of the melted unsalted butter and olive oil over them, followed by minced garlic.

Carefully place the seasoned beef on top of the potatoes. Drizzle the remaining melted butter and olive oil over the beef.

Cover the slow cooker and cook on low for 6 to 7 hours or on high for 3 to 4 hours without lifting the lid.

Once done, stir gently, check seasoning, add salt or pepper if needed, and garnish with parsley before serving.
