Here are some delicious ways to repurpose your Slow-Cooker Corned Beef Brisket Dinner leftovers:
1. Corned Beef Hash
Chop up the brisket, potatoes, and carrots, then sauté them in a skillet with onions and butter until crispy. Top with a fried egg for a hearty breakfast!
2. Reuben Sandwich
Layer sliced corned beef with Swiss cheese, sauerkraut, and Russian or 1000-Island dressing on rye or pumpernickel bread. Grill until golden brown and serve with a side of chips or a pickle.
Russian Dressing vs. Thousand Island Dressing: What’s the Difference?
Both Russian dressing and Thousand Island dressing are creamy, tangy condiments often used on sandwiches, burgers, and salads, but they have distinct differences:
- Russian Dressing: Spicier and more savory,made with mayonnaise, ketchup (or chili sauce), horseradish, Worcestershire sauce, and paprika
- Thousand Island Dressing: Sweeter and more mild, made with mayonnaise, ketchup, sweet pickle relish, and sometimes hard-boiled eggs
3. Corned Beef & Cabbage Soup
Simmer chopped corned beef, cabbage, potatoes, carrots, and beef broth for a cozy and flavorful soup. Serve alongside a grilled cheese sandwich on rye, sourdough, or a pretzel roll.
4. Irish Egg Rolls
Fill egg roll wrappers with shredded corned beef, cabbage, and Swiss cheese. Roll them up, fry or air-fry until crispy, and serve with Guinness mustard sauce.
5. Corned Beef Quesadillas
Stuff flour tortillas with corned beef, shredded cheese, and sautéed cabbage. Grill until crispy and serve with a spicy mustard, creamy horseradish sauce, or 1000-Island dressing.



6. Cottage Pie with Corned Beef
Swap ground beef for chopped corned beef in a classic cottage pie. Layer with leftover veggies, and frozen peas, top with mashed potatoes, shredded Swiss and/or gruyere cheese, and bake until golden.
Cottage Pie and Shepherd’s Pie are both classic, comforting meat pies topped with mashed potatoes, but the key difference lies in the protein used:
- Shepherd’s Pie is traditionally made with ground lamb, aligning with its name (since shepherds tend sheep).
- Cottage Pie is made with ground beef, making it a more common version in many households.
7. Corned Beef & Potato Breakfast Tacos
Warm up corn tortillas with scrambled eggs, chopped corned beef, potatoes, cheese, and a drizzle of your favorite hot sauce.
8. Cabbage & Corned Beef Slaw
Thinly slice raw cabbage and toss it with shredded corned beef, carrots, and a tangy peppercorn mustard vinaigrette for a fresh and crunchy salad. Serve atop a hot dog with 1000-Island dressing or over a bed of steamed rice.
9. Corned Beef Pizza
A crispy pizza crust (homemade or store-purchased) layered with creamy horseradish sauce or 1000-Island dressing, melty cheese, and corned beef, then topped with sour kraut, and a sprinkle of fresh herbs.
10. Corned Beef Chowder
A warm and hearty chowder featuring tender corned beef, potatoes, and vegetables in a rich, creamy broth. The perfect way to enjoy leftover corned beef!
