Roast beef sandwiches are a classic and satisfying meal that combines the savory flavors of roast beef with fresh arugula and tomato. Perfect for a quick lunch or a casual dinner, these sandwiches are easy to prepare and sure to please.
One ingredient that might not be commonly found in every home is horseradish. This adds a spicy kick to the mayonnaise spread, enhancing the overall flavor of the sandwich. If you don't have arugula, you can substitute it with another leafy green like spinach or lettuce.

How To Store / Freeze Your Sandwiches
- To keep your roast beef sandwiches fresh, wrap each sandwich tightly in plastic wrap or parchment paper before placing them in an airtight container. This helps maintain the bread's texture and prevents it from becoming soggy.
- Store the wrapped sandwiches in the refrigerator for up to 3 days. This ensures the roast beef and vegetables stay fresh and flavorful.
- For longer storage, consider freezing the sandwiches. First, wrap each sandwich in plastic wrap, then in a layer of aluminum foil. This double wrapping helps prevent freezer burn.
- Place the wrapped sandwiches in a freezer-safe bag or container, and label it with the date. You can freeze the sandwiches for up to 1 month.
- When ready to enjoy, thaw the sandwiches in the refrigerator overnight. This gradual thawing helps maintain the texture and flavor of the ingredients.
- To reheat, preheat your oven to 350°F (175°C). Remove the plastic wrap and rewrap the sandwiches in aluminum foil. Bake for 10-15 minutes until heated through.
- If you prefer a crispier bread, unwrap the sandwiches for the last few minutes of baking. This will give the hoagie rolls a delightful crunch.
- Avoid microwaving the sandwiches, as this can make the bread chewy and the vegetables soggy. The oven method ensures a more enjoyable texture and flavor.
How To Reheat Leftovers
Preheat your oven to 350°F (175°C). Wrap the roast beef sandwiches in aluminum foil and place them on a baking sheet. Heat for about 10-15 minutes until the roast beef is warmed through and the hoagie rolls are toasty.
If you prefer a quicker method, use a microwave. Place the roast beef sandwiches on a microwave-safe plate and cover them with a damp paper towel. Microwave on medium power for 1-2 minutes, checking halfway to ensure even heating.
For a crispy exterior, use a skillet. Heat a non-stick skillet over medium heat. Place the roast beef sandwiches in the skillet and cover with a lid. Heat for 2-3 minutes on each side, pressing down slightly with a spatula to ensure even warming.
If you have an air fryer, preheat it to 350°F (175°C). Place the roast beef sandwiches in the air fryer basket and heat for 3-5 minutes. This method will give you a crispy hoagie roll while keeping the roast beef tender.
For a toaster oven, preheat to 350°F (175°C). Place the roast beef sandwiches on the rack or a baking sheet and heat for 10-12 minutes. This method combines the benefits of an oven and a toaster, giving you a perfectly reheated sandwich.
