01 - Pat steak cubes dry with paper towels and season thoroughly with salt, pepper, Italian herbs, and smoked paprika, ensuring even coverage on all sides.
02 - Heat 1 tablespoon butter in a large skillet over medium-high heat. Sear steak cubes in batches for 1-2 minutes per side until browned. Transfer seared steak to the crockpot.
03 - Add minced garlic and onion to the skillet, adding more butter if needed. Sauté for 2-3 minutes until fragrant and softened.
04 - Pour beef broth and Worcestershire sauce into the skillet, scraping up browned bits from the bottom. Pour this flavorful mixture over the steak in the crockpot.
05 - Add remaining butter on top. Stir gently to combine. Cover and cook on LOW for 4 hours until steak is fork-tender and fully infused with flavors.
06 - Taste and adjust seasoning as desired. Garnish generously with fresh chopped parsley and serve hot.
