In a large skillet over medium-high heat, melt 1/4 cup of butter.
Add the beef cubes, seasoning them with salt and pepper. Sear the beef on all sides until browned (about 5-7 minutes). Transfer the beef to the slow cooker.
In the same skillet, add the remaining butter along with the minced garlic, rosemary, and thyme. Sauté for about 2 minutes until fragrant.
Pour in the beef broth, soy sauce, and Worcestershire sauce, stirring well to combine. Bring to a simmer for 2-3 minutes.
Pour the garlic butter mixture over the beef in the slow cooker, ensuring the meat is well coated.
Cover and cook on low for 6-8 hours or high for 3-4 hours, until the beef is tender and juicy.
Once done, taste and adjust seasoning if necessary. Serve hot, garnished with fresh parsley.
Notes
Serve the beef bites on a large platter, drizzled with the garlic butter sauce, and sprinkled with chopped parsley for a pop of color. For added flair, serve with toothpicks for easy enjoyment!
