Ingredients
Here is everything you need to create these fantastic corned beef sandwich recipes slow cooker style, from the brisket to the essential toppings.
For the Slow Cooker Corned Beef:
- 4 lbs corned beef brisket
- Aluminum foil (heavy-duty)
- Pickling spice packet (included with beef)
- 2 Tbsp brown sugar
- ½ tsp coarse black pepper
- ½ tsp ground coriander
- ½ tsp garlic powder
- ½ tsp paprika
- ¼ tsp onion powder
- 2 tsp hickory liquid smoke
For the Coleslaw:
- 4 cups chopped cabbage
- 1 cup shredded carrots
- 1 cup shredded white onion
For the Coleslaw Dressing:
- 1 cup mayonnaise
- 1 tsp Dijon mustard
- 1 tsp creamed horseradish
- 1 tsp sugar
- 2 tsp apple cider vinegar
- Few grinds coarse black pepper
- ½ tsp poppy seeds
For the Russian Dressing:
- 1 cup mayonnaise
- ¼ cup ketchup
- 2 tsp onion (finely diced)
- Splash Worcestershire sauce
- ¼ tsp paprika
For Assembly:
- 4 Tbsp butter, softened
- 12 slices marble rye bread
- 8 slices Swiss cheese
- Toothpicks (optional, for securing)
Notes & Substitutions
You typically find two cuts of corned beef brisket: flat cut (leaner, uniform slices) and point cut (more marbled, richer flavor). Either works beautifully here, but the flat cut is often preferred for slicing. For the best flavor, choose high-quality mayonnaise and fresh vegetables for your coleslaw. If you don’t have liquid smoke, you can omit it; it adds a subtle “pastrami-like” depth, but the rub provides plenty of flavor. Feel free to use good quality store-bought coleslaw or dressing to save time. For a classic Reuben, swap the coleslaw for well-drained sauerkraut. Provolone or cheddar cheese can substitute for Swiss, and any sturdy bread works if marble rye isn’t available.
Equipment
Making these fantastic corned beef sandwich recipes slow cooker style requires a few basic kitchen tools. You’ll need a 5-quart or larger slow cooker for the brisket. Gather large and small mixing bowls for the coleslaw and dressings. A sharp knife and cutting board are essential for slicing the tender corned beef. Finally, a large skillet or griddle will perfectly brown your rye bread. Measuring cups and spoons ensure accuracy.
Instructions
Follow these simple steps to create the most incredible corned beef sandwich recipes slow cooker style. You will love how easy it is!
- Prepare the Corned Beef Rub: In a small bowl, combine the pickling spice packet, brown sugar, black pepper, ground coriander, garlic powder, paprika, onion powder, and liquid smoke. Mix until well combined. Generously rub this mixture all over the corned beef brisket.
- Wrap the Corned Beef: Place the seasoned brisket on a large, heavy-duty sheet of aluminum foil. Wrap it tightly, then wrap it again three more times with additional foil, ensuring no liquid can escape during cooking.
- Slow Cook the Corned Beef: Carefully place the foil-wrapped corned beef into your slow cooker. Do not add any water to the cooker. Place the lid securely on the slow cooker. Cook on the LOW setting for 7-8 hours without opening the lid.
- Rest the Corned Beef: Once cooked, remove the entire foil-wrapped brisket from the slow cooker and place it on a cutting board. Let it rest for at least 20 minutes while you prepare the other sandwich components.
- Prepare the Coleslaw: In a large mixing bowl, combine the chopped cabbage, shredded carrots, and shredded white onion.
- Make the Coleslaw Dressing: In a small bowl, whisk together the mayonnaise, Dijon mustard, creamed horseradish, sugar, apple cider vinegar, coarse black pepper, and poppy seeds until smooth. Toss only the amount of coleslaw you plan to use immediately with a portion of the dressing to keep the rest fresh and crisp.
- Make the Russian Dressing: In another small bowl, combine the mayonnaise, ketchup, finely diced onion, Worcestershire sauce, and paprika. Stir until fully blended.
- Slice the Corned Beef: Carefully unwrap the rested corned beef. Discard any accumulated juices. Using a sharp knife, slice the corned beef thinly against the grain for maximum tenderness.
- Toast the Rye Bread: Lightly butter one side of each marble rye bread slice. Heat a large skillet or griddle over medium heat. Place the buttered bread slices in the skillet, butter-side down, and toast until golden brown and crisp.
- Assemble the Sandwiches: Spread a generous amount of Russian dressing on the unbuttered side of one toasted rye slice. Layer a substantial amount of thinly sliced corned beef on top. Add one or two slices of Swiss cheese. Top with a spoonful of the freshly dressed coleslaw. Place a second toasted rye slice on top, dressing side down. For stability, you can secure the sandwich halves with toothpicks.
- Serve and Enjoy: Cut the assembled sandwiches in half and serve them immediately.
Pro Tips & Troubleshooting
For extra tender meat, resist the urge to peek during cooking; keeping the lid closed maintains consistent heat and moisture. For detailed guidance on safely preparing food, the USDA offers comprehensive slow cooker food safety guidelines. Achieving perfect slices for your slow-cooked corned beef sandwiches requires letting the meat rest fully after cooking and using a very sharp knife to cut against the grain. If you are concerned about saltiness, briefly rinse the corned beef brisket under cold water before applying the rub, then adjust your seasoning later if needed. To ensure beautifully melted cheese, briefly cover your skillet with a lid while browning the bread, letting the residual heat melt the cheese perfectly onto the meat. To prevent soggy sandwiches, always dress the coleslaw just before assembly.
