If you don’t have Guinness, any beer will work, but darker beers add more depth of flavor.
Store-bought thousand island dressing saves time, but you can make your own if preferred.
For extra crispiness, press the sandwiches lightly with a spatula while toasting.
Can I use a different type of bread?
Yes, while rye bread is traditional for Reuben sandwiches, you can substitute with sourdough or any sturdy bread.
Can I make this without a slow cooker?
Yes, you can simmer the corned beef brisket on the stovetop in a large pot for 3–4 hours until tender.
What can I use instead of thousand island dressing?
Russian dressing is a great alternative, or you can mix mayonnaise, ketchup, and relish to create a similar flavor.
Can I make these sandwiches ahead of time?
You can prepare the corned beef brisket ahead and refrigerate it. Assemble and toast the sandwiches just before serving for the best texture.
