Take your lunch game to the next level with these irresistible Roast Beef Sandwich Slices, perfect for a quick yet indulgent homemade meal. Built on a foundation of crusty baguette or sandwich bread, these sandwiches are layered with tender, thinly sliced roast beef, creamy Swiss cheese, and a peppery handful of arugula. What truly sets this recipe apart is the zesty, flavor-packed horseradish mayo—a blend of mayonnaise, prepared horseradish, Dijon mustard, and a touch of seasoning for the ultimate tangy kick. Whether toasted to golden perfection or served as-is, these sandwiches come together in just 15 minutes, making them an ideal choice for busy weeknights or casual lunches. Pair with a crisp salad or a side of chips for a restaurant-quality experience at home.
Start by preparing the horseradish mayo. In a small bowl, combine mayonnaise, prepared horseradish, Dijon mustard, salt, and black pepper. Mix until smooth and set aside.
If using a baguette, slice it lengthwise and into 4 equal portions. If using sandwich bread, separate 8 slices. Optionally, lightly butter the inner sides of the bread for toasting.
On a flat skillet or grill pan over medium heat, lightly toast the bread (butter-side down if buttered) for 1-2 minutes until golden brown. Remove and set aside.
On the bottom half of each sandwich portion, generously spread the prepared horseradish mayo.
Layer with thinly sliced roast beef (roughly 100 grams per sandwich), followed by one slice of Swiss cheese per sandwich.
Add a handful of arugula or mixed greens for freshness.
Place the top half of the bread over the assembled ingredients.
If desired, return the assembled sandwiches to the skillet or grill pan and press gently for 1-2 minutes to melt the cheese slightly.
Slice the sandwiches in half for easy serving. Serve immediately and enjoy!
