Quick And Easy Steps To Making These Delicious Hot Roast Beef Sliders.

First Step: Hawaiian Rolls Mayonaisse

Using a sharp bread knife, slice the Hawaiian Rolls in half lengthwise.  As a result, the rolls will still be together for easier assembly.  Next, Spread the Mayonnaise on both the top and bottom half of the rolls.

Second Step: Chop Roast

Chop the roast in small pieces.  Next, add the roast on top of the bottom half of the slider buns.

Fourth Step: Cheese

Cover the roast with cheese.   To clarify, I mean from edge to edge with the cheese.  In other words, you want these roast beef sliders to be extremely gooey.   After the cheese layer, place the top half of the Hawaiian rolls with mayonnaise on them on top of the cheese and roast beef.

What type of cheese is best with roast beef?

When you think of a roast beef sandwich, it normally includes either swiss or cheddar cheese.  A good cheese that melts well like mozzarella, Gruyere, or provolone would be o.k.

Fifth Step: Brush The Top Of The Roast Beef Sliders

In a small bowl, combine the melted butter, Dijon Mustard, onion powder, and Worcestershire sauce.  Brush the tops of the sliders with the mustard mixture.

Last Step:  Bake The Roast Beef Sliders

  • Cover the Beef Sliders with foil.
  • Bake the sliders at 350 degrees for 15 minutes or until golden.
  • Remove the foil and bake an additional 10 minutes until the cheese is gooey and stringy.

This Roast Beef was also used to make Chipotle Roast Beef Sliders.

Growing up, my husband had a roast every Sunday.  I like to continue that tradition by eating roast on Sunday at least every month or two.  When I fix a large roast, we usually have some leftovers.  I decided to use the leftover roast beef in some hot sliders.

Ham & Cheese Sliders

My family loves Ham & Cheese Sliders on Hawaiian Rolls. The Hawaiian Rolls are sweet and go wonderfully with the other ingredients.  These sliders are not only delicious but cheesy and tangy.  I substituted the ham for leftover roast beef to make these Hot Roast Beef Sliders.  You could also use deli roast beef.  I chopped the roast beef small and added it to Hawaiian rolls along with the cheese.

Be sure to check out some of my other sliders that are not spicy.

The Hawaiian Rolls

On the Hawaiian rolls, I added melted butter, mustard, Worcestershire Sauce, poppy seeds, and more.  I then baked these sliders until hot and gooey.  Your mouth explodes after one bite with sweet, tangy stringy yumminess.

Roast Beef Sliders Big Hit

These sandwiches were a huge hit with my teenage boys.  They disappeared extremely fast, which is why I am glad this recipe makes twenty-four sliders.  You could always reduce this recipe by using one pack of twelve Hawaiian Rolls and half the remaining ingredients.  If you need a great appetizer or quick, easy, delicious sandwiches for lunch or a party, you will love these Hot Roast Beef Sliders.

How many sliders per person?

Sliders typically have two to three bites per slider.  A regular size sandwich is around two sandwiches.  I would say to plan on at least two sliders per person.
