Summer is in full swing which means sandwiches are being made on repeat! I love to take classic sandwich combinations and amp up the flavor. These sandwiches start with a tangy and slightly spicy 3 ingredient horseradish cream sauce, then are topped with so many delicious things. You can serve the sandwiches as is or you can turn them into pressed sandwiches. Check out the recipe card for how to press them. Roast beef sandwiches are delicious when served poolside, at the beach, on a picnic, or anywhere else your summer adventures take you!

What You Need To Make Roast Beef Sandwiches with Horseradish Cream Sauce

This recipe comes together with just a few ingredients but has such an elevated flavor for your everyday sandwich.

  • Horseradish Cream Sauce- This quick 3 ingredient sauce adds a punch of flavor as well as a nice creamyness to the sandwich. Combine mayo, dijon mustard and prepared horseradish for the ultimate roast beef accompaniment.
  • Ciabatta Bread– Ciabatta bread is perfect for this sandwich because it has a crusty exterior and chewy interior that provides a good crunchy base when toasted.
  • Arugula– The peppery bite of arugula brings a much needed freshness to the sandwich.
  • Roast Beef– For this sandwich I love to ask the deli counter for thinly sliced roast beef, so I can pile it high.
  • Mild Cheddar Cheese– Mild cheddar cheese brings just enough flavor to the sandwich, without overpowering the other flavors. (Tillamook is my favorite for sliced cheese)
  • Quick Pickled Onions– You can find the recipe for my Quick Pickled Onions here. They are the perfect acidic and crunchy finish to these sandwiches.
