Ingredients In Arby’s Roast Beef Sandwich

Here’s what you need to make these copycat sandwiches: Complete list of ingredients and amounts can be found in the recipe card below.

Homemade Arby’s Sauce: An expertly crafted mixture of ketchup, vinegar, mayo, sugar, and spices creates the same sauce that comes in those little packets, and you just have to whisk it up in a bowl!Roast Beef: Thinly sliced deli roast beef is similar to what Arby’s serves, and the best choice to make this copycat sandwich. You can get this from the deli counter, or buy the pre-packaged beef if that’s easier. For four sandwiches, get a pound of roast beef. Beef Broth: This is the key to warming the beef without drying it out. We’ll simmer the beef and the broth together very briefly on the stoveOnion Rolls: An Arby’s Beef and Cheddar comes on a soft roll with onions on it. Look for onion sandwich rolls, or use your favorite soft rolls instead. Cheddar Sauce: We aren’t buying pre-made cheese sauce because it’s really easy to make it fresh! You’ll need butter, flour, milk, sharp cheddar cheese, and a bit of salt.

How To Make an Arby’s Roast Beef Sandwich

Recipe Tips

Make it Your Own: This recipe was developed to taste as close to an Arby’s sandwich as possible, but you can make adjustments if you want things a bit different. Try adding some hot sauce to the sauce to make it spicier, or using a small amount of Velveeta with the cheddar to make the cheese sauce extra creamy. Don’t Overcook the Beef: Deli beef is already cooked, so all we need to do is warm it up. Just a minute or two in the simmering broth is plenty, any longer and the meat will get dry and tough.Try Other Sauces: Experiment with other homemade sauces on your Arby’s roast beef sandwiches. Raising Cane’s Sauce or horseradish Cocktail Sauce could be amazing!

Storing Tips

These sandwiches are best served immediately, but you can make the cheese sauce and Arby’s sauce ahead of time. Store both in the refrigerator in airtight containers for up to 3 days. Let the Arby’s sauce come to room temperature and re-heat the cheddar sauce on the stove before warming up the beef and making the sandwiches.

What To Serve With Copycat Arby’s Sandwiches

Curly Fries! You can buy Arby’s curly fries in the frozen section of your grocery store. I suggest tossing some in the air fryer while you’re getting the sandwiches ready. Save some Arby’s sauce for dipping! You might also enjoy making homemade french fries from scratch. There’s nothing like freshly fried potato fries, dipped in fry sauce or ranch dressing. Make your meal a bit healthier by serving a salad on the side. Try my Strawberry Spinach Salad or Healthy Red Cabbage Slaw.
