01 - Pat steak cubes dry with paper towels and season thoroughly with salt, pepper, Italian herbs, and smoked paprika, ensuring even coating 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 a touch more butter if needed. Sauté for 2-3 minutes until fragrant and translucent.
04 - Pour beef broth and Worcestershire sauce into the skillet, scraping up any browned bits from the bottom. Pour this aromatic mixture over the steak in the crockpot.
05 - Add remaining butter on top of the steak. Stir gently to incorporate. Cover and cook on LOW for 4 hours, or until steak reaches desired tenderness.
06 - Taste and adjust seasoning if necessary. Garnish with fresh chopped parsley and serve hot.
