Best Roast Beef Sandwich Recipe

Packed with flavors that’ll make your taste buds sing, this roast beef sandwich is a delicious experience. The combination of succulent roast beef, creamy Swiss cheese, and fresh veggies, nestled within hearty whole grain rolls, is just the tip of the iceberg. What takes this sandwich to the next level is the homemade horseradish sauce. It’s the creamy, zesty finishing touch with a kick that transforms a good sandwich into an unforgettable one.

Roast Beef: These tender slices of savory beef create the base of the sandwich. You can use deli meat or leftover homemade roast beef.  Rolls or Bread: I used whole grain rolls but you can use any type of bread you like. Swiss Cheese: This creamy cheese melts beautifully and adds a layer of richness. Feel free to use other types of cheese such as provolone cheese or cheddar cheese if you prefer. Red Onion: Adds a mildly pungent kick that complements the roasted beef. Baby Arugula: These peppery greens provide a layer of vibrant flavor and a pleasant crunch. Tomato: Fresh juicy sliced tomato adds both moisture and a touch of freshness. 

Mayonnaise: Creates the creamy base for the sauce. You can use store-bought or homemade mayonnaise.  Prepared Horseradish: Provides a delicious zesty, spicy flavor that gives the sauce its signature taste. Dijon Mustard: Adds a touch of refined tang and depth. Lemon Juice: Freshly squeezed lemon juice brightens up the sauce with a bit of acidity. Salt and Pepper: Perfectly season the sauce and help to develop the flavor. 

Get ready to elevate your sandwich-making game! With minimal effort, you can transform a plain roast beef sandwich into a tasty work of art with the right ingredients and a touch of creativity. In a mixing bowl, combine the mayonnaise, prepared horseradish, Dijon mustard, and freshly squeezed lemon juice. Then season the mixture with salt and pepper to taste, and whisk until thoroughly blended. Now, begin building the sandwiches. Take 2 slices of bread or the bottom of your buns and place some arugula followed by a couple of slices of tomato. Then sprinkle the tomato with salt and pepper to season. Next, add 4 slices of roast beef to each sandwich and then top the meat with a slice of Swiss cheese.  Once you’ve added the layers, drizzle plenty of that horseradish sauce over the roast beef, then add some thinly sliced onion if you like and another slice of tomato, if preferred. Finally, add the top bun and you’re ready to go.

Storage

I suggest enjoying your roast beef sandwich shortly after preparation. However, if you find yourself with leftovers, you can store them in the fridge for up to 2 days, wrapped in foil or plastic wrap. Any extra creamy horseradish sauce will keep for up to 5 days in the fridge when stored in an airtight container.
