Prepare the Ingredients:
Wash and halve or quarter the baby potatoes. Chop the onion and mince the garlic.
Season the Beef:
In a large bowl, combine the beef stew meat with salt, pepper, garlic powder, and onion powder. Toss the beef to coat it evenly with the seasonings.
Prepare the Slow Cooker:
Add the halved potatoes and chopped onion to the bottom of the slow cooker. Drizzle with olive oil and toss to coat. Spread them out in an even layer.
Add the Beef:
Place the seasoned beef on top of the potatoes in the slow cooker.
Make the Garlic Butter Sauce:
In a small bowl, combine the melted butter, beef broth, garlic, thyme, and rosemary. Stir to combine and pour the garlic butter sauce over the beef and potatoes.
Cook:
Cover the slow cooker and cook on low for 6-7 hours or on high for 3-4 hours, until the beef is tender and the potatoes are soft.
Serve:
Once done, garnish the dish with fresh parsley. Serve the beef bites and potatoes hot, either as a main dish or with a side of steamed vegetables.
