Ingredients

• 2 pieces (approximately 8 oz each) Ribeye steak
• 1 teaspoon Salt
• 1 teaspoon Black pepper
• 2 tablespoons Olive oil
• 3 tablespoons Butter
• 2 large (thinly sliced) Yellow onions
• 2 cloves (minced) Garlic
• 1 cup Beef broth
• 1 tablespoon Worcestershire sauce
• 4 pieces Baguette or sandwich rolls
• 4 slices Provolone cheese
• 1 tablespoon (chopped, optional for garnish) Fresh parsley

Directions

Step 1

Season the ribeye steaks generously on both sides with salt and black pepper. Set them aside to come to room temperature for about 20 minutes.

Step 2

In a large skillet over medium heat, melt 2 tablespoons of butter along with 1 tablespoon of olive oil. Add the sliced onions and a pinch of salt. Cook, stirring occasionally, for 15-20 minutes until the onions become golden and caramelized.

Step 3

Add the minced garlic to the onions and cook for 1-2 minutes until fragrant. Stir in the beef broth and Worcestershire sauce. Bring the mixture to a simmer and cook until it reduces slightly into a luscious, saucy consistency, about 5-7 minutes. Remove from heat and keep warm.

Step 4

Preheat your grill or grill pan to medium-high heat. Brush the grill grates lightly with olive oil. Drizzle the steaks with 1 tablespoon of olive oil and grill for 4-5 minutes on each side for medium-rare, or to your desired level of doneness. Remove the steaks from the grill and let them rest on a cutting board for 5 minutes before slicing thinly against the grain.

Step 5

While the steaks are resting, slice the baguette or sandwich rolls in half and lightly toast them on the grill for 1-2 minutes until golden and slightly crispy.

Step 6

To assemble, lay slices of grilled steak on the bottom half of each roll. Spoon a generous amount of the melted onion sauce over the steak, then top with a slice of provolone cheese. If desired, add a sprinkle of chopped fresh parsley for a pop of color and flavor.

Step 7

Serve the sandwiches immediately, warm and melty, and enjoy!
