These easy-to-make sandwiches are juicy, cheesy, and loaded up with amazing flavors from leftover roast beef! Whether you’re making one for lunch, trying to use up leftovers, or you’re making a dozen for game day, Roast Beef and Cheese Sandwiches are a guaranteed winner!

Roast beef sandwiches with melted cheese and sauteed onions in toasted buns are served with a side salad for a delicious weeknight meal, game day, or a get-together with friends.

Tender, juicy, flavorful roast beef – there’s just something about it.  Whether braised or done in the slow cooker, it’s always a hit at my house. I love making my Busy Day Pot Roast, and recently, with one successful dinner done, I had enough roast beef left over for a second meal.

That’s where this dish comes in.  Our family loves cheese steak sandwiches, and there is no doubt that leftovers make the best roast beef sandwich.

How To Make These Yummy Sammies

  1. Slice the rolls open and butter the top and bottom buns. Toast in the oven.
  2. In a medium size pan, heat the shredded leftover beef along with the stock. Cook until most of the liquid has been absorbed. Sauté the onions in butter until golden and soft.
  3. To build the sandwiches, on each roll, pile on a helping of the warm beef, top with shredded cheese, then place in the oven for 5–8 minutes until the cheese has melted.
  4. Add the sautéed onions on top of the melted cheese and serve.

People Often Ask…

Can Other Types Of Cheese Be Used?

Some of my favorites are Cheddar Cheese, Muenster, Mozzarella, Blue Cheese, and even cheese sauce.

What Kind Of Roll Is Best For Roast Beef Sandwiches?

I like to use Hoagie Rolls since they are large and sturdy. You can load up all the toppings into them without worrying about your sandwich falling apart. You can also use sub rolls which are a little longer, or even a bun if you would prefer that kind of sandwich.

What Kind Of Topping Are Good On A Roast Beef Sandwich?

All kinds of things! Try sliced tomato, lettuce, arugula, mayonnaise, spicy mustard, pepper jack cheese, hot sauce, horseradish sauce, or jardinière.

What If I Don’t Have Leftover Roast Beef?

No worries! You can use deli-style roast beef. Warm it in a large skillet with beef stock, a half teaspoon of garlic powder, and a tablespoon of Worcestershire sauce.

    I made these for Sunday night supper, and my husband declared them to be “exquisite”! I used your recipe for a slow cooker roast…used a ” chuck tender” roast and had to cook it a long time to get it to where it was tender enough to shred, but it had wonderful flavor. Next time I’ll use a cut of meat that gets tender quicker, but this made delicious sandwiches that my husband and son an I loved. Thanks for a great recipe!
