  1. Season steaks with seasoned salt and black pepper, and arrange in a single layer in a large baking dish. In a bowl, whisk together olive oil, balsamic vinegar, mustard, and rosemary. Pour mixture over filets, and turn to coat. Marinate for up to 30 minutes.
  2. While you are marinating the meat, melt the butter in a skillet over medium heat. Cook onion slices in butter until soft, then stir in sugar. Continue cooking until onions are caramelized. Set aside.
  3. Preheat grill for high heat on one side, and medium heat on the other side.
  4. Lightly oil the grill grate. Place steaks on the hot side of the grill, and cook for 10 minutes, turning once. When the steaks are almost done, move to the cooler side of the grill. Top each filet with a quarter of the caramelized onions and blue cheese. Close the lid, and continue cooking until the cheese is melted.

This is my recipe and it was changed by Allrecipes after submission. You need to use course ground dijon mustard. I have never tried regular dijon so I don't know how well that would go. Also, just heat up the grill, don't worry about one side being high and the other medium. I never submitted that. This is one of those recipes that you can just eyeball how much blue cheese and onions you want on each filet.


I rarely cook, but when I do I go out to make a great impression. I decided to use this recipe as a "makeup" dinner after an argument with my long-term girlfriend. Was it a hit? It was a home run, touch down, goal and swoosh all in one. I have often spent well over $100.00 for meals that couldn't touch this one with a ten foot pole. Five stars is not enough!!! I served this with green beans with onions, mushrooms and a light cream sauce and a fully loaded baked potato.


I made this for valentines day dinner for my husband, and we both agreed, this was the BEST steak I have ever fixed!! The marinade was really flavorful! Like some of the others, I used goat cheese instead of blue cheese and it was supberb!! I actually made this on my cast iron indoor grill and put it in my oven broiler to melt the cheese and it turned out great. I will definately be making this again and would highly recommend this to anyone to try.. It was extremely easy too!!
