Corned Beef and Swiss Panini on Rye

We had leftover corned beef, so I decided to make a corned beef and Swiss panini on rye for dinner. The meat and cheese paired so nicely with the crisp rye bread. I served this corned beef and Swiss panini on rye recipe with a big bowl of tomato soup and some baked sweet potato chips.
Corned Beef and Swiss Panini on Rye
Ingredients:
- Leftover corned beef
- Rye bread
- Swiss cheese
- Mayonnaise
- Grainy mustard
How to Make a Corned Beef and Swiss Panini on Rye:
Preheat your panini grill, a grill pan, or a large skillet over medium heat.
Break up the corned beef with your fingers and place it into a bowl. Add a tablespoon of water to the top of the corned beef, then cover with a paper towel. Place into the microwave and heat for 30 seconds.
Place a little bit of mayonnaise on top of one slice of bread. Add the corned beef on top, followed by a piece (or two) of Swiss cheese. Spread some grainy mustard on another slice of rye bread, then place it on top.
Place into your panini pan (or grill pan). Cook for 5 minutes or until crispy and golden brown. Side Note: I always cook my paninis dry, but feel free to butter your bread if you’d prefer.
Serve immediately. Enjoy! Side Note: You can also use a large skillet over medium heat to cook your sandwich evenly on both sides.

Love the simplicity of this and it makes for a tasty sandwich too. Thanks for posting Pam.
This is the perfect way to use up leftovers!
These sandwiches look delicious — very similar to a Reuben but without the kraut. I love using leftover corned beef to make sandwiches.
I have yet to find corned beef here in France, but maybe I have got the mane wrong! This looks good though. Have a good week, Diane
Great use of leftovers… it looks wonderful!!!
Turning leftovers into grilled cheese is definitely a very Kevin thing to do!! Lol. Looks great!
This sounds very good. Never got corned beef this year.
Leftover corned beef? Never happens. 5 of us consumed an entire 5 pound corned beef last night.
Sometimes I put the faintest coating of mayonnaise on my grilled sandwiches, but often I cook them dry. I don’t like dirty fingers while I’m eating. If only I had any leftover corned beef, so I could have panini like yours…
i know what i’m having for lunch tomorrow! i have everything i need!
I really want a panini!
Looks good – we had a corned beef sandwich for supper tonight.
no panini maker here, but my cast iron skillet makes a mean grilled sandwich!
and so it was…..
we had grilled reubens here for lunch two days in a row!
Perfect. I love a good panini and I can’t think of a better one than corned beef. Yummy!
I wish a large one for my lunch! It looks hearty and fantastic!
