Do You Love This Recipe Too?
I have a problem. A beautiful, delicious problem. Every single St. Patrick’s Day, I purposely cook a corned beef that is at least three times too large for my household. Why? Because my soul craves the leftovers more than the main event.
The moment that brisket is cool enough to handle, my brain starts singing the Reuben song. It’s a fact. For me, the boiled dinner is just the opening act. This sandwich, hot off the griddle, is the rockstar headliner. The crunch, the tang, the melt… it’s my edible happy place.
My Shopping List for This Recipe
Okay, team! The beauty here is you probably have most of this already. This is a scavenger hunt in your own kitchen. The only non-negotiable stars are that corned beef and some good, sturdy rye bread. Let’s round up the crew!

Lay everything out on the counter. This comes together fast, and we don’t want to be scrambling. Assembly line mode: activate!
- 4 slices of good quality rye bread (marble rye is my favorite!)
- 6-8 oz thinly sliced leftover corned beef
- 4 slices Swiss cheese
- 1/2 cup well-drained sauerkraut
- 1/4 cup Thousand Island dressing (store-bought is perfect, homemade Russian dressing is epic)
- 2 tablespoons softened butter (for that perfect golden crust)
Bringing This Recipe to Life (Step-by-Step)
Here we go! Fire up the stove and get ready for the best 10 minutes of your day. I want you to hear that sizzle. That’s the sound of happiness.
- Butter one side of each slice of rye bread. This buttered side will be the glorious, crispy exterior. Do not skip this!
- Flip the bread over. On the un-buttered side, spread a generous layer of Thousand Island dressing on all four slices. Be generous! This is our flavor glue.
- On two of the slices, layer on the Swiss cheese, then pile high with the sliced corned beef. Get it all on there!
- Take your well-drained sauerkraut and press it gently onto the corned beef. Top it with the second slice of Swiss cheese. This cheesy layer on top helps seal everything in.
- Place the remaining bread slices on top, buttered side facing out. You’ve built a beautiful, delicious tower.
- Heat a large skillet or griddle over medium-low heat. We want it hot, but not so hot it burns the bread before the cheese melts.
- Carefully place your sandwiches in the skillet. Cook for 3-4 minutes, until the bottom is a deep, golden brown and crispy.
- This is the tricky but fun part! Carefully flip the sandwich. Use a wide spatula and maybe a little prayer. Cook for another 3-4 minutes until the second side is perfect and the cheese is oozing out the sides.
- Remove from the skillet. Let it rest for just ONE minute. This keeps all the goodness inside when you cut it.
- Slice diagonally (it tastes better, trust me), serve immediately, and prepare to have your mind blown.
Fun Variations to Try Next Time
Once you’ve mastered the classic, the playground is open! Here are a couple of my favorite twists.
Try using Russian dressing instead of Thousand Island for a little more spice and tang. It’s a game-changer!

Notes
Enjoy your homemade Reuben Sandwich Corned Beef Leftovers Recipe!
No Swiss? No problem! A sharp white cheddar or even a nutty Gruyère works amazingly well. Use what you love.
For a “Rachel” sandwich, swap the sauerkraut for a crunchy, vinegar-based coleslaw. It’s a brighter, crunchier vibe that’s absolutely delicious.
How to Store, Freeze, and Reheat
Let’s be real, leftovers are unlikely. But if you have superhero-level willpower, here’s the plan.
Store any assembled-but-uncooked sandwiches in the fridge for up to a day. Wrap them tightly in plastic wrap. Cook from cold, adding a minute to each side.
I don’t recommend freezing the assembled sandwich. The bread gets soggy. Instead, freeze your leftover corned beef separately in airtight bags for up to 3 months. Thaw in the fridge overnight before making your fresh sandwich.
To reheat a cooked sandwich, the toaster oven or air fryer is your best friend! A few minutes at 350°F will bring back the crunch. The microwave will make it sad and soft.

A Quick Q&A on This Recipe
My bread burns before the cheese melts! Help!
I feel your pain! The key is medium-low heat. We need gentle, steady heat to melt that cheese from the inside out without torching the bread. If it’s browning too fast, just turn the heat down a notch. Patience is a virtue here, I promise!
Can I make this in a panini press?
ABSOLUTELY! A panini press is a fantastic shortcut. Just butter the outside of the bread, assemble, and press away! You’ll get those gorgeous grill marks and everything heats evenly. It’s a total win.
My sauerkraut makes the bread soggy. What am I doing wrong?
You gotta drain it, friend! This is the secret step. Take your sauerkraut and really squeeze out the excess liquid with your hands or press it in a colander. We want all the tangy flavor, not the extra wetness. A dry kraut is a happy kraut in a sandwich.
Look at what you did! You took those humble leftovers and turned them into a legendary diner-style sandwich. That is power. That is skill. That is downright delicious.
I live for these kinds of kitchen wins. They’re simple, they’re satisfying, and they make you feel like a total rockstar. This sandwich is a hug from the inside, and you absolutely earned it. It’s the perfect way to use up the rest of your Corned Beef and Cabbage feast.
