Filet Mignon with Marsala Caramelized Onions

Now that my son is a big-time teenager, he’s involved in high school activities most weekend nights.  This leaves plenty of time for my husband and I to have “date night!”  We very rarely go out to dinner.  I don’t like spending the money to take a chance that what I’m eating out is going to be as good or better than what I can prepare at home.  This is one of those dinner recipes that was made at home and better-than-restaurant-quality!

Marsala Caramelized Onions

This recipe all begins with the onions.  They’re slow cooked to caramelize them in the end.  Then they’re doused with Holland House Marsala Cooking Wine to give them a burst of delicious flavor the is going to go perfectly with your tender piece of filet.

After the marsala cooking wine has reduced down and absorbed completely into the onions, a sprinkle of fresh thyme finishes them off.  Give the onions a taste at this point and you will see how absolutely wonderful they are!

Prep Time: 40 minutes
Cook Time: 50 minutes
Total Time: 1 hour 30 minutes
Course: Main Course
Cuisine: American
Keyword: carmelized onions, filet mignon, marsala
Servings: 2 servings
Calories: 785kcal


  • 1 tablespoon olive oil
  • 2 medium onions, sliced thinly
  • 1 teaspoons kosher salt
  • ½ cup marsala cooking wine
  • 2 teaspoons fresh thyme
  • 2 medium sized filet mignon
  • kosher salt
  • 1 tablespoon olive oil
  • 1 medium garlic clove, peeled and sliced in half
  • freshly ground black pepper
  • 1 tablespoon butter
  • thyme leaves, for serving


  • Prepare the caramelized onions:  Heat the oil in a large skillet over medium heat. Add the onions and sprinkle with salt. Cook the onions over medium to medium high heat for 30 to 40 minutes, stirring often. The onions will begin to brown, soften and reduce down. Once they are looking nicely browned and softened (about 30 minutes in), add the marsala. Turn heat to medium high and continue to cook and stir until the wine cooks into the onions and evaporates. Remove the onions from heat and sprinkle in the fresh thyme. Set aside.
  • While the onions are cooking, prepare the filets. Pat the filets dry with a paper towel, sprinkle both sides with salt and let sit on a plate at room temperature.
  • Heat the oil in a large skillet at medium high heat. Pat the filets dry with a paper towel one more time, rub with garlic and sprinkle with pepper. Add the filets to the hot pan. Cook until browned, about 5 minutes on each side. Check with a meat thermometer for desired doneness: 120° for rare, 130° for medium rare.  Top each filet with ½ tablespoon butter and let it melt on top.
  • Divide the onions between two plates. Place a cooked filet on top of each pile of onions. Sprinkle with additional thyme and serve.
