Prepare the Ingredients: Pat the beef dry with paper towels and cut the baby potatoes into halves or quarters for even cooking.
Optional Sear: Heat olive oil in a skillet over medium-high heat and sear the beef bites until browned on all sides (3-4 minutes per batch).
Layer in Slow Cooker: Place the potatoes in the bottom of the slow cooker, followed by the beef bites on top.
Make the Sauce: In a small bowl, whisk together melted butter, minced garlic, soy sauce, and beef broth. Pour the sauce over the beef and potatoes.
Cook: Cover the slow cooker and cook on low for 7-8 hours or high for 4-5 hours, until the beef is tender and the potatoes are cooked through.
Garnish and Serve: Sprinkle chopped parsley over the dish before serving. Enjoy hot!
