01 - Pat the steaks thoroughly dry with paper towels. Rub 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 until shimmering. Sear steaks for 2 minutes per side until a rich brown crust forms. This step develops deep flavor but may be skipped if time is limited.
03 - Transfer seared steaks to the slow cooker insert. Arrange potatoes, carrots, onion slices, and minced garlic around and over the steaks.
04 - Pour beef broth and Worcestershire sauce evenly over the meat and vegetables. Ensure liquid is distributed throughout.
05 - Cover with lid. Cook on low setting for 6 hours until steaks are fork-tender and potatoes pierce easily.
06 - Taste and adjust seasoning with additional salt and pepper if desired. Ladle onto plates, spooning broth and vegetables over the steaks. Garnish with fresh parsley.
