01 - Pat the steaks dry with paper towels and season both sides generously 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. Sear seasoned steaks for 2 minutes per side until a golden-brown crust forms, enhancing depth of flavor.
03 - Transfer seared steaks to the slow cooker. Arrange halved potatoes, sliced carrots, onion rings, and minced garlic around and over the meat.
04 - Pour beef broth and Worcestershire sauce evenly over the ingredients, ensuring the liquid distributes throughout the cooker.
05 - Cover and cook on low setting for 6 hours until steaks are fork-tender and potatoes offer no resistance when pierced.
06 - Taste the cooking liquid and adjust seasoning if desired. Sprinkle with freshly chopped parsley and serve hot directly from the slow cooker.
