01 - Pat the steaks thoroughly dry with paper towels. Rub both sides evenly with salt, pepper, paprika, thyme, and rosemary, pressing the spices into the meat.
02 - Heat olive oil in a large skillet over medium-high heat until shimmering. Sear seasoned steaks for 2 minutes per side until a deep brown crust forms. Transfer immediately to the slow cooker.
03 - Arrange halved potatoes, sliced carrots, onion wedges, and minced garlic around and over the steaks in the slow cooker insert.
04 - Pour beef broth and Worcestershire sauce evenly over the meat and vegetables. Do not stir.
05 - Cover with lid. Cook on low setting for 6 hours until steak forks apart easily and potatoes are tender throughout.
06 - Taste the cooking liquid and adjust seasoning with salt and pepper if desired. Sprinkle with fresh chopped parsley just before serving.
