Ingredients

  • 1/2

    cup mayonnaise

  • 1/4

    cup prepared white horseradish

  • 4

    tablespoons butter - (1/2 stick) divided

  • 3

    beef tenderloin 1"-thick steaks

  • 3

    medium onions thinly sliced

  • 8

    ounces large shiitake mushrooms stemmed, and caps thinly sliced - (abt 5 cups)

  • 1

    cup beef broth

  • 4

    large croissants halved horizontally, and lightly toasted

  • 2

    cups arugula

Directions

Mix mayonnaise and horseradish in small bowl to blend. Melt 1 tablespoon butter in heavy large skillet over medium-high heat. Sprinkle tenderloin steaks with salt and pepper. Add steaks to skillet and cook to desired doneness, about 5 minutes per side for medium-rare. Using tongs, transfer steaks to work surface. Melt 3 tablespoons butter in same skillet over medium-high heat. Add onions; sauté until dark brown, about 25 minutes. Add mushrooms; sauté until tender, about 5 minutes. Add broth; boil until juices are reduced to glaze, stirring occasionally, about 1 minute. Season onion mixture to taste with salt and pepper. Place 1 croissant bottom, cut-side up, on each of 4 plates. Spread each with horseradish mayonnaise and top with 1/2 cup arugula. Thinly slice steaks and divide among croissants. Top with onion mixture. Spread remaining mayonnaise on cut side of croissant tops. Place tops on sandwiches. This recipe yields 4 servings. Although this sandwich tastes great with a croissant, any bread can be used.
