Oh, we love March and celebrating St. Patrick’s Day! One of our favorite recipes to make for casual entertaining is our Corned Beef Sliders on Hawaiian rolls. We’ve bought all of our ingredients at Trader Joe’s but you can shop anywhere. And the beauty of these cheesy sliders is you can use either corned beef (leftovers?) or pastrami, and cold corned beef sliders are the BEST!

What’s the difference between corned beef and pastrami?

Corned beef is one of my favorites, and in fact, I have one cooking right now! But often I hear people ask, what’s the difference between corned beef and pastrami? They’re both great, and you can use either for this recipe today.

BEST Trader Joe's Cheesy Irish Sliders Recipe

Corned beef and pastrami both taste about the same. It’s the proccess of how the meat is cured that makes them different. After curing, pastrami is usually coated in a dry rub of spices before it is smoked. Corned beef is boiled. Corned beef is popular served as Corned Beef and Cabbage, a traditional Irish meal.

Trader Joe's Cheesy Irish Sliders - how to make

How do you make Corned Beef Sliders?

  1. Preheat oven to broil.
  2. Slice the rolls in half and line the bottom half on the bottom of a large baking (cookie) sheet. You want a pan that will hold 24 small rolls (or use 2 separate pans).
  3. Top the bottom of the rolls with pastrami (or corned beef), and sliced cheese.
  4. Broil the sliders (bottom) until the cheese starts to melt; then remove from the oven.
  5. Adjust the oven to 350 degrees.
  6. Spread pesto on the inside of the top of the rolls. Place the tops of the rolls on the melted cheese/meat bottom sliders.
  7. In a small bowl, melt the butter and add the mustard, poppy seeds, and brown sugar. Lightly whisk until mixed well.
  8. Using a pastry brush, brush the butter topping over the top rolls.
  9. Place back in the oven and bake for another 10 minutes, until the cheese has melted and the tops are lightly browned.

Tips and substitutions:

Remember, this recipe is great if you have leftover corned beef. Or, just buy pastrami in the store. I used 3 packages for a large recipe, and the best Irish cheese (Dubliner).

Dubliner is a sweet, aged cheese over a year old, with a granular texture to it. And it melts up just fine! It’s manufactured by Carbery, located in County Cork, Republic of Ireland. We buy the Kerrygold label.

Use any kind of slider rolls.

In place of sauerkraut, use coleslaw (on the sliders if you choose, or on the side).

Serve with coleslaw, sauerkraut, or Guinness Potato Chips. Amazing!

Dublin, Ireland

The Dubliner Cheese is named after the city of Dublin, although it is made in Cork. We loved our time in Dublin a few years back. It was a thrilling experience for Uncle Gabe to walk us through the streets of Dublin and point out, that’s where your parents met, Paul, up in that dance hall. Or, walking up to Paul’s mom’s red front door where she grew up. Then walking through the Catholic church where Tom and Betty were married–oh, wow, just, WOW!

And then driving to Kimage to see the neighborhood Paul’s dad grew up in, which was once a slum. Paul’s dad grew up with Christy, from My Left Foot movie.

Easy Trader Joe's Cheesy Irish Sliders Recipe

This recipe makes 24 small sliders (if you use Trader Joe’s Aloha Rolls, which on are the smaller side).

Don’t forget you can make ahead, and brush with the butter sauce right before baking!

We can’t wait to make these again soon–for St. Patrick’s Day! ENJOY!
