01 - Rub the beef cubes evenly with kosher salt and black pepper, ensuring all surfaces are coated.

04 - In a small bowl, whisk together the melted butter, minced garlic, thyme, rosemary, paprika, and red pepper flakes until fully combined.
05 - Pour the garlic butter mixture over the beef and vegetables. Add the beef broth to the slow cooker.
06 - Cover and cook on LOW for 7–8 hours until the beef is fork-tender and the potatoes are cooked through.
07 - Gently stir the mixture, taste, and adjust seasoning if necessary. Garnish with chopped fresh parsley before serving.
