Recipe Instructions
Step 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.
Step 2
Preheat grill for high heat on one side, and medium heat on the other side.
Step 3
While you are marinating the meat, melt 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.
Step 4
Lightly oil the grill grate. Place steaks on the hot side of the grill, and cook for 10 minutes, turning once. When 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 cheese is melted.
