Thin slices of deli roast beef top toasty crostini along with a tangy horseradish cream, arugula, a sprinkle of Gruyere cheese and diced tomatoes. They are perfect for your next party and are SO GOOD!
Roast Beef Crostini are a favorite appetizer recipe! I recently made them for a holiday cocktail party as a group of neighborhood friends gathered to kickoff the Christmas season. My big tray of these 2 bite roast beef appetizers were a hit! They were gobbled up in no time at all.
Crispy yet soft crostini is topped with a tangy horseradish cream, peppery arugula, thin slices of roast beef, nutty Gruyere cheese and bright red tomato. The combination of flavors is DELICIOUS!

how to make crostini
I struck upon the perfect crostini recipe while sipping wine and nibbling on appetizers at my friend Linda's home. She has the perfect crostini as it's slightly crisp and just a little soft. It is ideal accompaniment to my basil hummus, pimento cheese, creamy New England Clam chowder, and these roast beef crostini.
Here's the crostini details:
- Cut a long thin loaf of bread into ½ inch slices.
- Brush with extra virgin olive oil and sprinkle with kosher salt.
- In a hot cast iron skillet (a large sauté pan will work too), quickly toast each side of the bread slices. Flip the bread after a minute or so for the perfect crostini.
- Serve warm or at room temperature.

- Toast the bread ~ In a hot pan, quickly toast slices of a long thin loaf that are brushed with extra virgin olive oil and sprinkled with kosher salt.
- Mix the horseradish cream ~ In a small bowl, combine the sour cream, mayonnaise, and prepared horseradish.
- Assemble the roast beef crostini ~ For each beef appetizer, spread some of the horseradish cream on a crostini. Top with a couple arugula leaves, about a half slice of deli roast beef, another dab of the horseradish cream, some shredded Gruyere cheese and diced tomato.
expert tips
- Use a thin loaf of bread for the crostini ~ for the perfect 2 bite appetizer, choose a loaf of bread that is about 2 to 3 inches in diameter.
- Ask the deli counter to thinly slice the roast beef ~ My first choice for the roast beef is medium rare Boar's Head which is available at most deli counters.
