Philly Cheese Steak Sliders with Leftover Roast Beef


Philly Cheese with Leftover Roast Beef Lazuli Farms Recipe


I'm all about creating meals that tantalize the taste buds BUT that don't mean spending hours making them!  I'm all about finding ways to make things easier in the kitchen.  That's why we love cooking roasts all year round!

Today, let's chat roast beef.

A 2.5 to 3.5 pound beef roast can be used to create a couple of meals for a family of 4 to 6 people.  Cook the roast in advance (the slow cooker is perfect for this) and shred the beef into small pieces.  Then get creative to make a few different meals!

Check out this post to find out the top FIVE ways to use leftover roast beef.

In today's recipe, we're making Philly Cheesesteak Sliders made with leftover roast beef.  There's something about the mix of beef, caramelized onions & peppers, and melted cheese that makes these sandwiches so amazing!

Try different cheese for a fun twist!  We used Klondyk gouda (tastes like Swixx Cheese) and herb gouda from Sylvan Star Cheese - both added such delicious flavour!

You don't have to use garlic aioli on your sandwiches, but you'd really be missing out!  Garlic aioli is a mayonaise-based sauce that is packed with garlicky punch - just what you need for these Philly Cheesesteak sandwiches!  Find the recipe for quick & easy garlic aioli here.

Philly Cheese Steak Sliders with Leftover Roast Beef Recipe


  • 12 small buns or 8 medium buns, sliced in half
  • 2 to 3 cups leftover roast beef, shredded (find beef roast here)
  • cheddar, gouda, or swiss cheese, sliced
  • garlic aioli for drizzling on top (recipe here)
  • 1 white or yellow onion, sliced into strips
  • 1 green, red, or yellow bell pepper, sliced into strips
  • 1 to 2 tablespoons bacon grease, lard, or butter


Preheat a cast iron pan over medium heat.  Melt the bacon grease, lard, or butter in the pan.  Add the onions and saute for a couple of minutes before adding the bell pepper strips.  Stirring frequently, cook the onion & pepper mixture until soft and lightly caramelized.

Preheat the oven to 375F.

Season the shredded beef to taste with salt & pepper or an all-purpose seasoning of your choice.

Place the bun halves side by side on a baking sheet.  Lay cheese slices onto half of the buns and spoon the onion & pepper mixture over top.  Go ahead and omit the onion & pepper mixture for those in your family that don't love them!  On the other half of the buns, spoon the roast beef onto the buns.  Drizzle garlic aioli over the roast beef. 

Transfer the baking sheet to the oven and bake for 10 to 15 minutes until the cheese is melted and bubbly.  Remove from the oven and allow to cool for a few minutes.  Now it's time to bring the bun halves together:  place a cheese covered bun half on top of the roast beef bun half.  Repeat for all buns.

Serve with your favorite salad or pickled veggies and enjoy!
