Prepare Ingredients: Gather all ingredients and cut the beef into bite-sized pieces. Parboil the halved baby potatoes in boiling water for about 5 minutes if you prefer softer potatoes.

Sear the Beef: Heat olive oil in a large skillet, sear the beef for 3-4 minutes on each side until browned.

Make the Garlic Butter Sauce: Mix melted butter, minced garlic, onion powder, smoked paprika, dried thyme, dried rosemary, salt, and black pepper in a bowl until well blended.

Assemble in Slow Cooker: Layer the parboiled baby potatoes at the bottom, followed by seared beef bites. Pour the garlic butter sauce over them and add beef broth.

Slow Cook the Mixture: Cover the slow cooker and cook on low for 6-8 hours or high for 3-4 hours until beef is fork-tender.

Rest Before Serving: Let the dish rest in the slow cooker for 10 minutes after cooking, then serve warm.
