In a slow cooker, add the beef and halved baby potatoes, spreading them evenly across the bottom.

In a small saucepan, melt the butter over medium heat, stirring gently for about 5 minutes until it becomes liquid gold.

Add in the minced garlic, garlic powder, salt, and pepper to the melted butter. Stir until fragrant, about 1-2 minutes.

Pour the garlic butter mixture over the beef and potatoes in the slow cooker, ensuring they are well-coated.

Cover and cook on low for 6-8 hours or on high for 3-4 hours, until the beef is fork-tender and the potatoes can be easily pierced with a fork.

Before serving, garnish with freshly chopped parsley for a burst of color and flavor.
