Recipe Information
Ingredients
- 1 pound ribeye steak
- 1 teaspoon salt
- 0.5 teaspoon black pepper
- 3 tablespoons olive oil
- 2 medium yellow onion
- 1 teaspoon granulated sugar
- 8 ounces button mushrooms
- 2 cloves garlic
- 4 pieces French baguette or ciabatta roll
- 4 tablespoons mayonnaise
- 1 cup arugula
Instructions
Season the steak on both sides with salt and black pepper. Let it rest for 10 minutes while prepping other ingredients.
Slice the onions thinly. In a skillet, heat 1 tablespoon of olive oil over medium heat. Add the onions and cook, stirring often, for about 15 minutes until golden and tender. Sprinkle with granulated sugar and continue to cook for another 5 minutes to caramelize. Remove from the skillet and set aside.
Wipe the skillet clean and heat another tablespoon of olive oil over medium heat. Add the sliced mushrooms and cook for 8-10 minutes until browned and softened. Mince the garlic and add it to the mushrooms, cooking for 1 more minute. Remove from heat and set aside.
Preheat the grill or grill pan over medium-high heat. Brush the steak with 1 tablespoon of olive oil and place it on the grill. Cook for 4-5 minutes per side for medium-rare, or to your preferred level of doneness. Remove the steak from the grill and let it rest for 5 minutes before slicing thinly against the grain.
While the steak rests, slice the baguettes or ciabatta rolls in half and toast them lightly on the grill, if desired.
Spread 1 tablespoon of mayonnaise on each bottom half of the bread. Layer slices of steak, caramelized onions, mushrooms, and a handful of arugula on top. Close the sandwich with the upper half of the bread.
Serve immediately and enjoy your Grilled Steak Sandwich with Mushrooms and Caramelized Onions!
