26 Must-Have Ingredients for the Ultimate Roast Beef Sandwich

A roast beef sandwich is a classic meal featuring tender, juicy slices of roasted beef layered between bread or a roll. While a simple roast beef sandwich with just meat and bread can be delicious, you can take it to the next level with flavorful condiments, cheeses, vegetables and other tasty toppings. Here are 26 ingredients to elevate your roast beef sandwich game:

Sauces and Spreads

  • Horseradish Sauce – Creamy, pungent horseradish sauce pairs perfectly with roast beef’s rich flavor. Mix prepared horseradish with mayonnaise, Greek yogurt or sour cream.

  • Mustard – Yellow, Dijon, honey or whole grain mustards all add a tangy accent to roast beef. Spread it directly on the bread or mix into a sauce.

  • Swiss – With its mild, slightly sweet flavor, Swiss cheese is reliably delicious on roast beef sandwiches.
