Ingredients

• 1 pound Ribeye steak
• 2 large Yellow onions
• 2 tablespoons Olive oil
• 2 tablespoons Butter
• 1 teaspoon Balsamic vinegar
• 1 teaspoon Salt
• 0.5 teaspoon Black pepper
• 0.5 teaspoon Garlic powder
• 4 slices Provolone cheese
• 1 large Baguette
• 1 cup Arugula
• 2 tablespoons Mayonnaise
• 1 tablespoon Dijon mustard

Directions

Step 1

Slice the yellow onions into thin rings. Set them aside.

Step 2

Heat 1 tablespoon of olive oil and 1 tablespoon of butter in a large skillet over medium-low heat.

Step 3

Add the sliced onions to the skillet, and cook for 20-25 minutes, stirring occasionally, until they are golden and caramelized. Add the balsamic vinegar toward the end of cooking for an extra depth of flavor. Remove from the skillet and set aside.

Step 4

While the onions are cooking, season both sides of the ribeye steak with salt, black pepper, and garlic powder.

Step 5

In a separate skillet, heat the remaining tablespoon of olive oil and butter over medium-high heat.

Step 6

Sear the steak for 3-4 minutes on each side or until it reaches your desired level of doneness. Remove the steak from heat and allow it to rest for 5 minutes before slicing it thinly against the grain.

Step 7

Cut the baguette into 4 equal portions and slice each piece in half lengthwise. Lightly toast the baguette in the oven or on a skillet.

Step 8

In a small bowl, mix the mayonnaise and Dijon mustard until well combined.

Step 9

Spread the mayo-mustard mixture on both halves of each baguette portion.

Step 10

Assemble the sandwiches by layering sliced steak, caramelized onions, provolone cheese, and fresh arugula on the bottom half of each baguette portion. Top with the other half of the baguette.

Step 11

If desired, place the assembled sandwiches in a preheated oven at 350°F (175°C) for 5 minutes to melt the cheese.

Step 12

Serve immediately and enjoy your caramelized onion steak sandwich!
