A comforting slow cooker beef Manhattan recipe that is easy to prepare, perfect for cozy dinners, and features tender beef in rich gravy served over toasted bread with melted cheese.
Searing the beef before slow cooking adds deeper flavor but can be skipped for time. Toast bread well to prevent sogginess. Adjust gravy thickness with broth or flour as needed. Fresh parsley or a squeeze of lemon juice brightens the dish. For gluten-free, use cornstarch instead of flour and gluten-free bread. For dairy-free, substitute plant-based cheese and olive oil for butter.
