What Cut of Beef is Best for Roast Beef Sandwiches?

Ideally, the meat for your roast beef sandwich should be quite lean without being too chewy. A top loin roast is perhaps your very best option, giving you lots of flavor without too much fat. For more economical options that taste just as great, try using bottom loin or eye round steaks.

Which Toppings Should I Put on my Roast Beef Sandwich?

Toppings make all the difference when it comes to your roast beef sandwich! Looking for the tastiest toppings to elevate this simple meal? You can’t go wrong with a slice or two of your favorite cheese. Provolone and Swiss cheeses melt easily for an indulgent addition to your sandwich. Other popular toppings include crunchy microgreens, slices of creamy avocado slightly-sweet caramelized onions.

What Kind of Cheese is Best for This Recipe?

We usually opt for Provolone cheese due to its flavor and “melt-ability” but you’ve got quite a few options here. Gouda, Asiago, Swiss and Mozzarella are all delicious options. In general, a white cheese that melts is your best bet for an irresistible roast beef sandwich.

What Bread Should I Use?

For a classic roast beef sandwich like they serve at Arby’s, try to get Kaiser rolls. These simple, round rolls are crispy on the outside and soft in the middle. If you can’t get these rolls, there’s no need to worry. Any round bread/roll from a local bakery or grocery store will do the trick. The star of the show is the meaty roast beef, so don’t be too fussy about your bread.

Which Condiments are Best for a Roast Beef Sandwich?

There’s nothing quite like the tangy, spicy, zesty taste of horseradish sauce on a roast beef sandwich. For some reason, roast beef and horseradishes are a match made in taste bud heaven! Other tasty condiment options include mayo (plain or spicy), Dijon mustard or sour cream. Feel free to play around with your favorite sauces – roast beef tastes great with nearly everything!

How to Make Roast Beef Sandwich

  • (Optional) Add oil to a large skillet over medium heat. Once hot, add onions and sauté for about 10 minutes or until soften, adding balsamic vinegar halfway. Once the onions are nicely brown and caramelized, remove from heat.
  • In a medium bowl, mix together the horseradish, mayo, sour cream and mustard. Set aside.
  • Set up an assembly station by laying out the roast beef, cheese slices, arugula, sliced tomato, onions, sauce and buns.
  • Preheat the oven to 350°F. Brush the buns lightly with olive oil. Then put them in the hot oven or griddle for 2 to 3 minutes.
  • Spread the horseradish cream sauce onto the bottom buns. Sprinkle on some arugula or greens. Add several slices of roast beef followed by some salt and pepper. Layer on the caramelized onions, cheese, tomatoes and a few more greens. Add the tops of the buns and serve.

Tips for a Hot Roast Beef Sandwich

This versatile sandwich can be enjoyed hot or cold. For those who like a hot roast beef sandwich, the appeal is in the warm bread and the melted cheese. Brush your rolls with butter or olive oil and toast them in the oven or on the griddle. Next, spread your condiments and assemble the roast beef and toppings on your sandwich.

What goes with Beef Sandwiches?

Beef up your sandwich with these tasty side dishes! Roast beef sandwiches are great on their own, but you can take things to the next level with any one of these additions. We love French fries or potato wedges with a roast beef sandwich and these can easily be prepared at home. Cole slaw, mashed or roasted potatoes and steamed veggies are other delicious options for you to enjoy with your roast beef sandwich.

Prep: 10 minutes
Cook: 20 minutes

Servings: 6

Ingredients 

Toppings

  • 1 red onion, sliced into rings
  • 2 teaspoons olive oil
  • 1 tablespoon balsamic vinegar

Arby’s Sauce

  • 2 tablespoons creamed horseradish, or 1 tablespoon freshly grated horseradish
  • ¾ cup mayonnaise, see note
  • ¾ cup sour cream, see note
  • 2 tablespoons mustard, Dijon or yellow

For the Sandwich

  • 6 kaiser rolls, or similar buns
  • 1 pound roast beef, sliced
  • 6 slices provolone cheese, or Swiss cheese
  • 1 cup arugula, or microgreens
  • 1 large tomato, sliced
  • salt and pepper, to taste

Instructions 

  • Saute the Onions (You can skep this step if you prefer to use raw onions): Place a large skillet over medium heat. Add the oil and onions. Sauté for 10 to 12 minutes stirring regularly, adding the balsamic vinegar halfway through. Once the onions are nicely brown and caramelized, remove from heat.
  • Make the Sauce: In a medium bowl, mix together the horseradish, mayo, sour cream and mustard. Set aside.
  • Prepare to Assemble: Set up an assembly station by laying out the roast beef, cheese slices, arugula, sliced tomato, onions, sauce and buns.
  • Toast the Buns: Preheat the oven or griddle to 350°F. Brush the buns lightly with olive oil. Then put them in the hot oven or griddle for 2 to 3 minutes.
  • Assembly: Spread the horseradish cream sauce onto the bottom buns. Sprinkle on some arugula or greens. Add several slices of roast beef followed by some salt and pepper. Layer on the caramelized onions, cheese, tomatoes and a few more greens. Add the tops of the buns and serve.

Notes

  • Onions: If you are in a rush, you can skip sauteeing the onions and put them on raw.
  • Mayo: Use real mayo instead of whipped topping for the best taste. For a lighter option, you can use light mayo.
  • Sour Cream: You can use light sour cream for a lighter option.
