Rye bread is a flavorful bread that pairs perfectly with the other ingredients and can usually be found in the bakery section.

Ingredients For Slow Cooker Corned Beef Reuben Sandwiches
Corned beef brisket: A flavorful cut of beef that is cured in a brine solution, giving it a distinctive taste. Rye bread: A type of bread made with rye flour, known for its slightly sour and hearty flavor. Sauerkraut: Fermented cabbage that adds a tangy and crunchy element to the sandwich. Swiss cheese: A mild, nutty cheese that melts beautifully and complements the other flavors. Russian dressing: A creamy and tangy dressing made with mayonnaise, ketchup, and various seasonings. Butter: Used to grill the sandwiches to a golden brown perfection.
Technique Tip for Making Reuben Sandwiches
To ensure your corned beef is tender and flavorful, make sure to fully submerge it in water while cooking in the slow cooker. This helps to evenly distribute the heat and prevents the meat from drying out. Additionally, when slicing the corned beef, always cut against the grain to achieve the most tender slices. For the perfect grilled sandwich, use a cast-iron skillet for even heat distribution and a crispy, golden-brown crust.

- Slice the corned beef thinly and place it in an airtight container. This prevents it from drying out and keeps it fresh.
- Store the sauerkraut separately in a sealed container to avoid sogginess in the sandwiches.
- Keep the swiss cheese in its original packaging or wrap it tightly in plastic wrap to prevent it from absorbing other odors in the fridge.
- For the rye bread, store it in a bread box or a sealed plastic bag to maintain its softness and prevent staleness.
- If you plan to freeze the corned beef, wrap it tightly in aluminum foil or freezer paper, then place it in a freezer-safe bag. This helps prevent freezer burn and keeps the meat flavorful.
- To freeze the assembled sandwiches, wrap each sandwich individually in plastic wrap, then place them in a large freezer-safe bag. This ensures they stay together and are easy to grab for a quick meal.
- Label all containers and bags with the date to keep track of freshness.
- When ready to enjoy, thaw the sandwiches in the fridge overnight. This helps maintain the texture and prevents them from becoming soggy.

How to Reheat Leftovers
Oven Method: Preheat your oven to 350°F (175°C). Wrap each sandwich in aluminum foil to keep it moist. Place the wrapped sandwiches on a baking sheet and heat for about 15-20 minutes, or until the corned beef is warmed through and the cheese is melted.
Skillet Method: Heat a skillet over medium heat. Place the sandwich in the skillet and cover with a lid to help the cheese melt. Cook for about 3-4 minutes on each side, or until the bread is crispy and the corned beef is heated through.
Microwave Method: Place the sandwich on a microwave-safe plate. Cover with a damp paper towel to prevent it from drying out. Microwave on medium power for 1-2 minutes, checking halfway through to ensure even heating.
Toaster Oven Method: Preheat your toaster oven to 350°F (175°C). Place the sandwich on the rack or a baking sheet. Heat for about 10-15 minutes, or until the corned beef is warmed through and the cheese is melted.
