Elevate your lunch game with these delicious roast beef sandwiches. Perfect for a quick meal or a casual get-together, these sandwiches combine the savory flavors of roast beef and cheddar cheese with the peppery bite of fresh arugula. The addition of mayonnaise and optional horseradish adds a creamy and tangy touch that brings everything together.
If you don't typically stock arugula in your fridge, you might need to pick some up at the supermarket. This leafy green adds a fresh, peppery flavor that complements the richness of the roast beef. Additionally, if you enjoy a bit of heat, consider grabbing some horseradish to mix with the mayonnaise for an extra kick.

Ingredients For Roast Beef Sandwiches Recipe
Roast beef: Thinly sliced, this is the star of the sandwich, providing a rich and savory flavor.
Cheddar cheese: Adds a creamy and slightly sharp taste that pairs well with the beef.
Bread rolls: Split and toasted, these provide the base and structure for the sandwich.
Arugula: Fresh and peppery, this leafy green adds a burst of flavor and a bit of crunch.
Mayonnaise: Creamy and smooth, it helps to bind the ingredients together and adds moisture.
Horseradish: Optional, but adds a spicy kick that enhances the overall flavor profile.
Technique Tip for This Recipe
To enhance the flavor of your roast beef sandwiches, consider lightly warming the roast beef slices in a skillet over medium heat before assembling the sandwich. This will not only bring out the rich flavors of the beef but also help the cheddar cheese melt more evenly when layered on top. Additionally, for a more gourmet touch, try using a mix of mayonnaise and horseradish to create a zesty spread that complements the savory roast beef perfectly.

How to Store or Freeze Your Sandwiches
- Allow the roast beef sandwiches to cool completely before storing. This helps prevent condensation, which can make the bread soggy.
- Wrap each sandwich individually in parchment paper or wax paper. This keeps the sandwiches fresh and prevents them from sticking together.
- Place the wrapped sandwiches in an airtight container or a resealable plastic bag. Make sure to squeeze out as much air as possible to maintain freshness.
- Store the sandwiches in the refrigerator if you plan to consume them within 2-3 days. For longer storage, place them in the freezer.
- To freeze, label each package with the date to keep track of freshness. Sandwiches can be frozen for up to 1 month.
- When ready to eat, thaw frozen sandwiches in the refrigerator overnight. This ensures even thawing and maintains the texture of the bread rolls.
- For a warm sandwich, reheat in the oven at 350°F (175°C) for about 10 minutes or until the cheddar cheese is melted and the sandwich is heated through. Avoid microwaving as it can make the bread rubbery.
- If you prefer a cold sandwich, simply unwrap and enjoy straight from the refrigerator. The arugula will still be crisp and the roast beef flavorful.
How to Reheat Leftovers
Preheat your oven to 350°F (175°C). Wrap each roast beef sandwich in aluminum foil to keep the bread rolls from drying out. Place them on a baking sheet and heat for about 10-15 minutes until the cheddar cheese is melted and the roast beef is warmed through.
For a quicker method, use a microwave. Wrap the sandwich in a damp paper towel to maintain moisture. Microwave on medium power for 1-2 minutes, checking halfway through to ensure even heating.
If you have a panini press or a sandwich grill, preheat it and place the sandwich inside. Grill for 3-5 minutes until the cheese is melted and the bread is crispy.
For a stovetop method, heat a skillet over medium heat. Place the sandwich in the skillet and cover with a lid. Heat for 2-3 minutes on each side, pressing down gently with a spatula to ensure even heating and a crispy exterior.
