Horseradish cream is a sauce made or freshly grated or prepared horseradish, sour cream, chives, mayonnaise, apple cider vinegar, salt and pepper. It’s fairly simple to make, requiring a toss of the ingredients to a bowl, followed by a good mixing of the spoon–that’s it!

Horseradish cream makes for a the perfect pairing with steak appetizer crostini appetizers and also grilled or cast-iron steaks. So if you have any leftover horseradish cream, save it for steak night. It will keep in the refrigerator for 4 days.

How to Make Steak Crostini with Horseradish Cream

  • Make Horseradish Cream Sauce. Start by making the sauce, first. This will give the flavors time to marry while making crostini and steak.
  • Prepare Crostini. Choose a french baguette loaf and slice it into 12  ½-inch slices. Toast for 4 minutes then set aside.
  • Cook Steak in a Cast-Iron Skillet. This method is ideal for perfectly cooked, juicy steak.

What Type of Steak Should You Use?

Ah yes, ribeye steak.This beautiful cut of meat, displaying swirls of red and white marbling along with a thick fat cap is my go-to choice for steak.

It’s richly flavored and the marbling yields a melt-in-your-mouth texture that is just delightful. Ribeye cuts of steak are higher priced than other cuts of steak, but definitely worth it, especially when making crostini. Going for a cut of steak that’s tough can result in a chewy, less pleasurable experience which is something you don’t want with this small bites.

When cooking steak, it’s important to temper your meat before cooking. Tempering entails removing the steak from the refrigerator 30-45 minutes before cooking as this will allow meat to cook more evenly.
