Ingredients
  

For the Sandwiches
  • 4 slices Sourdough bread thick-cut
  • 8 oz Deli roast beef thinly sliced, high quality
  • 4 slices Sharp cheddar cheese or 4 oz shredded
  • 1/4 cup Red onion very thinly sliced
  • 2 tbsp Unsalted butter softened, or mayonnaise
For the Horseradish Aioli
  • 1/4 cup Mayonnaise
  • 1 tbsp Prepared horseradish drained well
  • 1/2 tsp Dijon mustard
  • 1/4 tsp Black pepper freshly ground
  • Pinch Salt

Equipment

  • Large Skillet or Griddle
  • Spatula
  • Small Bowl
  • Knife

Method
 

Prepare the Horseradish Aioli
  1. In a small bowl, combine mayonnaise, prepared horseradish, Dijon mustard, black pepper, and a pinch of salt. Mix well until smooth. Set aside.
Assemble the Sandwiches
  1. Lay out the sourdough bread slices. Spread a thin layer of the horseradish aioli on the inside of each slice. On two slices, layer half of the roast beef, followed by half of the red onion, and then two slices (or half the shredded amount) of sharp cheddar cheese. Top with the remaining roast beef. Place the other aioli-spread bread slice on top to complete the sandwiches.
  2. Evenly spread the softened butter (or mayonnaise) on the outside of each side of both sandwiches. This creates a golden, crispy crust when grilled.
Grill the Sandwiches
  1. Heat a large skillet or griddle over medium heat. Once hot, carefully place the assembled sandwiches into the skillet. Cook for 3-4 minutes per side, or until the bread is golden brown and crispy, and the cheese is melted and gooey. You may need to press down gently with a spatula to ensure even contact and browning.
Serve
  1. Carefully remove the hot sandwiches from the skillet. If desired, cut them in half diagonally before serving immediately. Pair with a side of chips, a pickle, or a simple green salad for a complete meal.

Notes

For an extra layer of flavor and texture, briefly warm the roast beef in the skillet for 30 seconds before assembling the sandwich. You can also add a few arugula leaves inside the sandwich for a peppery bite. For a spicier kick, increase the amount of horseradish in the aioli.

How I Make Gourmet Roast Beef and Cheddar Melt Sandwich Step-by-Step

My process begins with the creamy horseradish aioli – a simple yet impactful blend of mayonnaise, prepared horseradish, Dijon, salt, and pepper. It truly makes the sandwich sing. Next, I assemble: layering tender roast beef, thinly sliced red onion, and generous sharp cheddar between buttered sourdough. Then, I grill them until golden and the cheese is gloriously gooey. It’s a joy every time, much like crafting a perfect smoked gouda apple grilled cheese.

My Tips for the Perfect Outcome

  • Butter sourdough generously; it ensures a truly golden, crispy crust.
  • Use medium heat; this allows the cheese to melt perfectly before the bread burns.
  • Slice red onion very thinly for a delicate, balanced flavor.
  • Don’t overstuff; a balanced sandwich cooks evenly and is much more enjoyable.

How I Serve and Store This Dish

I love serving this Roast Beef and Cheddar Melt Sandwich piping hot off the grill, ideally with crisp potato chips or a refreshing side salad. It’s truly best enjoyed immediately. For any rare leftovers, I wrap them tightly, refrigerate, then reheat gently in a dry skillet or oven to preserve crispness. It’s a delicious, easy meal anytime, much like my apple cheddar turkey panini.

Frequently Asked Questions

Faq 1

What kind of roast beef works best for this sandwich? I always recommend using thinly sliced deli roast beef, preferably fresh from the deli counter. Its superior quality and remarkable freshness significantly impact the sandwich’s overall flavor and texture, making each bite truly gourmet and memorable.

Faq 2

Can I make the horseradish aioli ahead of time? Absolutely! I often prepare the horseradish aioli a day or two in advance. Storing it in an airtight container in the refrigerator allows the flavors to beautifully meld even further, enhancing the sandwich’s deliciousness when it’s finally assembled.

Faq 3

What’s a good cheese substitute if I don’t have sharp cheddar? While sharp cheddar is my top choice, a good quality provolone or Gruyere could also work wonderfully in this Gourmet Roast Beef and Cheddar Melt Sandwich. Just select a cheese that melts beautifully and complements the rich, savory roast beef perfectly.

Faq 4

How do I ensure my sandwich gets a perfectly golden, crispy crust? My secret for a perfectly golden, crispy crust is using unsalted butter generously on the outside of each sourdough slice. Grilling over medium heat ensures the bread toasts slowly and evenly, developing that coveted crunchy exterior without burning.
