I've been making little tweaks to this family favorite for years. Prep everything ahead, then layer up the crostini right before party time. —Greg Fontenot, The Woodlands, Texas

  1. Preheat oven to 350°. Place baguette slices on baking sheets; brush with 2 tablespoons olive oil. Bake until toasted, about 10 minutes.
  2. Place carrots and water in a large saucepan; bring to a boil over medium-high heat. Cook, uncovered, 10 minutes. Add sugar; cook on medium heat until thickened, about 15 minutes, stirring occasionally. Remove from heat; add desired amount of horseradish and mix well. Cool.
  3. Meanwhile, in a small saucepan over medium-low heat, melt butter. Cook and stir onions until caramelized, 10-12 minutes; cool. Stir in cheeses, mayonnaise and sour cream.
  4. In a large skillet, heat remaining olive oil over medium-high heat. Add steak; cook 4-6 minutes on each side until meat reaches desired doneness (for medium-rare, a thermometer should read 145°; medium, 160°; well-done, 170°). Let stand 5 minutes; cut into thin slices.
  5. To serve, spread cheese mixture on each baguette slice. Add a piece of steak; top with carrot mixture. Yield: 3-1/2 dozen.
Editor’s Note: Top loin steak may be labeled as strip steak, Kansas City steak, New York strip steak, ambassador steak or boneless club steak in your region.
