Notes

For best results, use chuck roast for maximum flavor and tenderness. Add the cheddar cheese during the last 30 minutes of cooking to prevent it from becoming oily. Leftovers can be stored in the refrigerator for up to 3 days. Reheat in the microwave or oven until warmed through. For a richer flavor, sear the steak before adding it to the slow cooker.
