Prepare the Beef: Heat a large skillet over medium-high heat and drizzle with olive oil. Season beef stew meat with salt and pepper, and sear for 2–3 minutes on each side until browned. Transfer to the slow cooker.

Sauté the Garlic: In the same skillet, reduce heat to medium and add butter. Once melted, add minced garlic and sauté for about 1 minute until fragrant. Pour over the beef in the slow cooker.

Create the Flavorful Sauce: Pour in beef broth and Worcestershire sauce, scraping up browned bits from the bottom. Stir in dried thyme and rosemary before pouring over beef.

Add the Potatoes: Toss halved baby potatoes into the slow cooker, ensuring they are covered with the garlicky sauce.

Slow Cook to Perfection: Place remaining butter pieces on top, cover, and cook on low for 6–7 hours or high for 3–4 hours until beef is fork-tender and potatoes are soft.

Final Touches: Remove the lid, taste, and adjust seasoning. Garnish with freshly chopped parsley before serving.
