Ingredients for Smothered Filet Mignon

• 4 (6 ounce) filet mignon steaks
• 1 teaspoon seasoned salt
• ½ teaspoon black pepper
• ¼ cup extra-virgin olive oil
• 2 tablespoons balsamic vinegar
• 1 teaspoon Dijon mustard
• 1 tablespoon fresh rosemary, chopped
• 1 large onion, thinly sliced
• 1 tablespoon butter
• ¼ cup crumbled blue cheese

Step-by-Step Cooking Instructions

1. Season the Steaks

   Season each filet mignon generously with seasoned salt and black pepper, pressing the spices into the meat for maximum flavor.

2. Mix the Marinade

   In a bowl, whisk together olive oil, balsamic vinegar, Dijon mustard, and chopped rosemary until well-combined.

3. Marinate

   Place steaks in a shallow dish, pour the marinade over, and turn to coat. Cover and refrigerate for 30 minutes for a tender, marinated steak.

4. Preheat & Grill

   Preheat your grill or grill pan over medium-high heat. Lightly oil the grates, then grill steaks 4–6 minutes per side for medium-rare, or to your preferred doneness.

5. Caramelize Onions

   While steaks cook, melt butter in a skillet over medium heat. Add sliced onions and stir occasionally until soft and golden, about 10 minutes.

6. Rest & Plate

   Remove steaks from the grill and let rest 5 minutes. Top each steak with warm caramelized onions and a sprinkle of blue cheese.

Tips for Perfect Grilled Steak

• Room temperature: Let steaks sit 20 minutes before grilling for even cooking.
• Oil the grill: Prevent sticking and achieve perfect sear marks.
• Use a thermometer: Aim for 130°F for medium-rare.
• Rest time matters: Retains juices for a tender bite.
