This is how to make the best corned beef sandwich after St. Patricks Day for lunch or dinner served on bread or rolls. You can use leftover corned beef when it has or with fresh meat right out of the oven with mustard and pickles.
Maybe you call this a corn beef sandwich, I get it, my daughter did until she was like a teen too and it was too cute to correct her. 😉 We always seem to have a bit of meat left over the popular holiday when this is served and love new ways to enjoy it at home.
What Sauce Goes with Corned Beef Sandwich
It is all about the corned beef mustard!!! Yes you can use bottled from the store but make ours to be over the top delicious. It is sweet with a tang which you just can’t get with the packaged variety. It just takes 5 minutes to whip up and so worth it.
When I start this process I typically make and slice thin our corned beef in the oven. If you want the best of the best use fresh rye or pumpernickel bread. Beyond that are unique toppings that will take your bite from good to OMG out of this world like; sauerkraut and a slice of Swiss cheese. Another add in that is a must is pickles, dill and nothing else.
Ingredient Notes
The first thing you need to do is get this marinated cut of beef cooked until it is fork tender and super duper easy to slice thru. If it is a bit tough to move the knife thru the meat it needs longer, period. As for how you get this done, that is up to you. I will say that if I had to choose from all of them, Slow Cooker Corned Beef Brisket is where it is at. Period.
The best bread is rye, pumpernickel if you want a strong flavor, or wheat if you want just the basic slices of bread (2 per sandwich). For the outside if I am crisping a bit I will spread butter on it.
We like to add a few large leaves of lettuce just to give it a fresh crunch, and some added nutrition to the mix. Homemade dill pickles (or Claussen) are the other “veggie” we add and should not be skipped. Slice thin or buy this way so they lay flat.
I mean once you have the meat ready and bread or rolls then the inside add ins are up to you. For us we do all out with the dill flavors. I have come up with an ever popular sauce linked above to use along with sandwich pickles and if I have cheese on hand I will add a slice of that too. OR make deconstructed with rye bread to make our Corned Beef Casserole.
Slider buns are smaller and typically square or round in shape, designed to hold a single small sandwich or burger. They are perfect for serving smaller portions or game day appetizer-sized air fryer sandwiches like we did with these.
What is in a classic Reuben?
This is the main protein in this popular meal too, and the only difference is the toppings. Swiss is a must when making those. Then you would transition this one to a reuben with some corned beef quick sauerkraut on rye bread with Russian dressing or Thousand Island dressing instead.
Should it be served hot or cold?
That is up to you really. This time I show it cold. if you wanted to heat you could do so in a multitude of ways but in a pan with the outside bread pieces coated with butter is most common. You just need about 3 minutes on each side over medium heat to do so. You could make these as a version of our grilled cheese in toaster oven too though which would make it crispier and more ooey gooey.

Spread mustard on the non buttered side of the other piece of bread. (a slice of cheese like Swiss could be added on top of the mustard so it melts in the pan if you like too)
- Place 4-5 slices of corned beef on bread in the pan with other mustard side facing down with buttered side facing up. Once browned on one side, flip to the other.

How to Cook Melt in Your Mouth Corned Beef
Cooking Corned Beef and Cabbage right is key. And the texture is where it’s at. Tender tender is what you want. Below we will share how to get this done in the oven but will include a few other methods throughout this post so you can find the right fit for you.
If you want the all time fastest method of them all, use a pressure cooker. You can follow our Ninja Foodi corned beef post to follow that. Any brand that is electric will work with this one though. Instant Pot or Crockpot Express has the same necessary function needed for this one.
What to Make with Leftover Corned Beef Other Than Sandwiches
You can use leftovers the next way inside the middle of Grilled Cheese, or our Corned Beef Soup too which is a great tweak. Or dice up and put inside a chowder is great too. Jump to recipe and get started.
