Prepare the Beef: Start by cutting the beef chuck into 1-inch cubes. Trim any excess fat for a healthier dish.

Sear the Beef (Optional): In a skillet over medium-high heat, sear the beef cubes for 2-3 minutes on each side until browned. This step is optional but adds more depth to the flavor.

Add to Slow Cooker: Place the beef (seared or not) into the slow cooker.

Add Vegetables: Add the sliced carrots and diced potatoes to the slow cooker.

Mix the Sauce: In a separate bowl, combine the red wine, beef broth, tomato paste, and dried thyme. Mix until well blended.

Combine: Pour the sauce mixture over the beef and vegetables in the slow cooker. Stir gently to combine.

Set the Cooker: Cover and cook on low for 6-8 hours or on high for 4-5 hours, until the beef is tender and the flavors have melded together.

Taste and Adjust: About 30 minutes before serving, taste the stew and adjust seasoning if necessary. You can add salt and pepper to enhance the flavors.

Serve: Once finished, give the stew a good stir and serve hot.
