We took the comforting flavors of French onion soup and turned them into an easy bistro-style steak dinner. Tender filet mignon gets smothered with sweet caramelized onions and topped by a crispy, Swiss cheese–covered crostini. To double this recipe use 2 large skillets and prepare one 4-serving recipe in each. Serve with green beans and mashed potatoes with buttermilk and chives.

Ingredient Checklist


Instructions Checklist
  • Sprinkle steaks with dried onion, 1/4 teaspoon salt and pepper. Heat 1 tablespoon oil in a large skillet over medium-high heat. Add the steaks and reduce the heat to medium. Cook, turning once, until desired doneness, 3 to 6 minutes per side for medium-rare. Transfer the steaks to a plate and tent with foil.

  • Position a rack in upper third of oven. Preheat broiler.

  • Add the remaining 1 tablespoon oil to the pan. Add onions and sherry, cover and cook over medium heat, stirring occasionally, until the onions are tender and golden brown and the liquid has evaporated, 10 to 12 minutes. Sprinkle flour over the onions and stir to coat. Add broth, thyme and the remaining 1/4 teaspoon salt; cook until bubbling and thickened, about 1 minute more.

  • Remove from the heat and return the steaks and any accumulated juice to the pan. Pile up some of the onions on top of the steaks. Top each steak with a slice of baguette and some cheese. Transfer the pan to the oven and broil until the cheese is melted and bubbling, about 2 minutes. Serve the steaks with the onions and sauce.


Note: Sherry is a type of fortified wine originally from southern Spain. “Cooking sherry” sold in many supermarkets can be high in sodium. Instead, get dry sherry that's sold with other fortified wines at your wine or liquor store.

Excellent Choice for an easy fancy dinner I made this dish about two weeks ago...my boyfriend and I liked it so much we decided to make it again tonight for New Year's Eve. It is easy but looks fancy and the flavor of the steak and the surrounding sauce is excellent. A slightly expensive cut of meat but well worth it with this recipe. Enjoy it! Pros: Easy healthy and impressive for guests Cons: Make sure you have a dinner pan that can go in the oven at high heat Read More
