reuben slider recipe for st. patrick's day party

Corned Beef Sliders

In looking at my holiday calendar, I can see that St. Patrick’s Day is approaching fast.

Brooks would love to have corned beef for dinner. Me, I can go another way. I am not a fan of corned beef but I am always willing to make it for him.

Not willing to start from scratch, I figured that buying a corned beef already make work well. It’s the thought that counts, right?

But the corned beef itself is huge! So what am I do to with all the leftover corned beef that we are going to have? Make sandwiches! But not just any sandwich… sliders!

They also make a great game day recipe.If you like a classic reuben sandwich you are going to love this.

Ingredients Needed

Corned Beef – I prefer leftover corned beef but fresh sliced from the deli works great too!

Swiss Cheese – Use thin sliced Swiss cheese or havarti.

Mustard – I like whole grain mustard for the flavor and texture but Dijon mustard makes a great substitute.

Egg – Large egg mixed with a little water and beaten to make the egg wash.

Thousand Island Dressing – Feel free to use Russian dressing instead of the 1000 island if you prefer that.

How to Make Corned Beef Sliders

First: Roll the puff pastry sheets out thin and place on a parchment lined baking sheet pan. Spread the bottom one with some whole grain mustard. Leave an inch clear all the way around for folding.

Second: Place a layer of corned beef slices over the mustard. Cover with slices of Swiss cheese.

Third: Place the second sheet of puff pastry on top. Fold over the edges and crimp with a fork to seal. Brush with egg wash.

Fourth: Bake at 400F for 20 minutes or until golden brown. Remove, cut in squares, and serve!

To make the sliders perfect for St. Patrick’s Day, I serve them with some homemade thousand island dressing to make it like a Reuben sandwich.

Can I put sauerkraut in them?

Adding sauerkraut inside the sandwich will add too much moisture and make the sliders soggy. If you want to have some, add it on top when eating or add some to the dipping sauce.

Can I make these ahead of time?

These baked sliders are best right out of the oven but you can make them the say before and then reheat them in the oven at 325F for 5-10 minutes or until warm again.

Store any leftovers in an airtight container in the fridge for up to 3 days.

Can I make these with dinner rolls?

If you don’t want to use the puff pastry, or you prefer regular little sandwiches, put the ingredients on slider buns, sweet Hawaiian rolls, or some rye bread. Just like these funeral sandwiches.

Brush with melted butter and sprinkle with poppy seeds.

Tapas Tips & Tricks

  • Be sure to roll the puff pastry thin so you can get as many sliders as possible.
  • Brush with whole grain mustard but feel free to use Dijon if you prefer.
  • If you don’t have any leftover corned beef brisket, you can get some from the deli counter.
  • Slice your corned beef and cheese very thin.
  • Brushing the pastry with egg wash will help you get a brown and crispy pastry.
  • The pastry will puff up while baking (it looks really cool) but it will settle down once you pull it out of the oven.

Equipment

Ingredients

  • 1 package puff pastry 2 sheets
  • 9 slices Swiss Cheese sliced very thin
  • 15 slices Corned Beef sliced very thin
  • 2 tablespoons Whole Grain Mustard
  • 1 egg

1000 island dressing

  • 1/2 cup mayo
  • 1/8 cup ketchup
  • 1 teaspoon onion powder
  • 1 teaspoon paprika
  • 1 tablespoon vinegar
  • 1 tablespoon pickle relish I use dill relish

Instructions

  • Preheat the oven to 400F.
  • Place a piece of parchment paper or silicone baking sheet on a metal baking pan.
  • Roll each puff pastry sheet out to a 12-inch square. It will be thin, just lightly dust the surface with flour.
  • Spread the mustard on one sheet of pastry leaving a 1/2 inch border.
  • Layer the cheese over the mustard.
  • Layer the corned beef on top of the cheese.
  • Cover with the other sheet of puff pastry.
  • Roll and crimp the edges with a fork, sealing completely.
  • Brush the top with an egg wash.
  • Bake for 20 minutes.
  • The pastry will puff up and turn golden brown on top.
  • Remove from oven and cool for a minute. The pastry will fall a bit.
  • Slice up and serve with dressing! I slice on the diagonal to make them even prettier. You will leave small triangles of pastry on the corners, but I just eat them while I plate them, as a treat.

  15. That looks so good! I made a dangerous discovery at the grocery store not long ago… puff pastry in the refrigerated section! No more defrosting and planning ahead!!! Plus it is a bigger sheet and rolled around parchment so you are ready to rock and roll. I love the idea of using it to made sandwich bites! Thanks so much for sharing at Throwback Thursday!

    1. An apple would be good but I was worried about the water in the apples. Might try cooking them down first.

    I remember the first time I made puff pastry too, not too hard but pretty time consuming. Sometimes just the challenge and being able to say ‘I did that’ is worth it though. I think I will opt for the store bought stuff for these sliders. They look fabulous

  30. I think this is the best looking way to use corned beef that I’ve ever seen. I’m such a sucker for flat pies. I would not trust myself left alone with your snack!!

  33. I’m far too lazy to make my own puff pastry, but I am very happy to buy it pre-made. And I would love these sliders!!
