  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.


  • Tip
  • Aluminum foil can be used to keep food moist, cook it evenly, and make clean-up easier.

I didn't care for the taste that the marinade gave my filets...was disappointing, especially after reading all the good reviews. As always, thanks for sharing but I won't make this again.

The balsmic marinade is so good. Through the whole dinner we kept going mmmm.... mmmm.... We don't like blue cheese so I used mozzerella instead.I can't wait to make it again. Thanks.

This was a great twist to an old favorite. Turns out the Dijon works just fine, but I will try the course dijon next time and compare. Used splenda to carmelize my onions rather than sugar and c...

Great! The only thing I did different was use brown sugar instead of the white, red wine instead of the vinegar, and mixed the blue cheese with cream cheese.
