Ingredients

• 300 grams Ribeye or sirloin steak
• 2 tablespoons Olive oil
• 1 teaspoon Salt
• 1 teaspoon Black pepper
• 1 loaf Baguette or ciabatta bread
• 1 tablespoon Butter
• 1 large Yellow onion
• 1 teaspoon Red wine vinegar
• 3 tablespoons Mayonnaise
• 1 tablespoon Whole-grain mustard
• 1 handful Arugula leaves

Directions

Step 1

Remove the steak from the fridge and let it rest at room temperature for 20-30 minutes before cooking. This ensures even cooking.

Step 2

Heat 1 tablespoon of olive oil in a skillet over medium heat.

Step 3

Slice the yellow onion thinly and add it to the skillet. Cook, stirring occasionally, for 7-10 minutes until the onions are caramelized and golden brown. Add the red wine vinegar and stir through. Remove from the skillet and set aside.

Step 4

Season the steak generously with salt and black pepper on both sides.

Step 5

Return the skillet to high heat and add 1 tablespoon of olive oil. When the oil is hot and shimmering, sear the steak for 2-3 minutes on each side for medium-rare, or adjust the time for your preferred doneness. Remove the steak from the pan, cover with foil, and let it rest for 5 minutes.

Step 6

In a small bowl, mix the mayonnaise and whole-grain mustard to make the mustard mayo.

Step 7

Slice the baguette or ciabatta loaf in half lengthwise and spread butter over the cut sides. Toast the bread in the skillet for 1-2 minutes until golden and crispy.

Step 8

Thinly slice the rested steak across the grain.

Step 9

To assemble the sandwich, spread the mustard mayo on the bottom half of the bread. Layer with the caramelized onions, steak slices, and a handful of arugula leaves. Top with the other half of the bread.

Step 10

Slice the sandwich into portions and serve immediately. Enjoy your delicious steak sarnie!
