Step 1: Prepare the Beef

1. Season the Beef: Pat the beef bites dry with paper towels to remove excess moisture. Season with salt, pepper, garlic powder, and smoked paprika.
2. Optional Sear: For enhanced flavor, heat olive oil in a skillet over medium-high heat. Sear the beef bites in batches, browning each side for 1-2 minutes. This step is optional but adds depth to the dish.

Step 2: Prepare the Potatoes

1. Toss the halved or quartered potatoes with olive oil, salt, and pepper in a large mixing bowl. This ensures they are evenly seasoned and ready to absorb the garlic butter sauce.

Step 3: Make the Garlic Butter Sauce

1. In a small bowl, whisk together melted butter, minced garlic, thyme, rosemary, beef broth, and Worcestershire sauce.

Step 4: Assemble in the Slow Cooker

1. Place the seasoned potatoes in the bottom of the slow cooker.
2. Layer the seasoned beef bites on top of the potatoes.
3. Pour the garlic butter sauce evenly over the beef and potatoes, ensuring everything is well coated.

Step 5: Cook

1. Cover the slow cooker with the lid.
   • For low heat: Cook for 6-8 hours.
   • For high heat: Cook for 3-4 hours.
2. Check the beef and potatoes for tenderness before serving. Both should be fork-tender and infused with the garlic butter flavor.

Step 6: Garnish and Serve

1. Sprinkle chopped parsley over the dish for a pop of freshness.
2. Optional: Add a sprinkle of grated Parmesan for extra richness.
3. Serve warm, straight from the slow cooker, with crusty bread or a green salad on the side.
