Instructions
1-First, focus on the caramelized onions: Melt 2 tablespoons butter and 1 tablespoon oil in a skillet on low heat, then add 2 large sliced onions. Cook them for about 1 hour, stirring occasionally, until they turn a beautiful golden brown. This step builds a sweet base that makes the sandwich irresistible.
2-Next, prepare the roasted garlic butter: Preheat your oven to 400 degrees Fahrenheit. Take 1 large head of garlic with the top trimmed, drizzle it with olive oil, and season with salt and pepper. Wrap it in foil and bake for 45 minutes until it’s soft. Once done, squeeze the garlic into 4 tablespoons of softened butter and mix well for that creamy spread.
3-Now for the herb mayo: In a bowl, combine 1/2 cup mayonnaise, 1 teaspoon Dijon mustard, 1 tablespoon lemon juice, 1/4 cup fresh chopped chives, and 1/4 cup fresh chopped dill. Add salt and pepper to taste, then mix everything until it’s smooth and flavorful.
4-Cooking the Steak: For the steaks, pat 2 pounds of New York Strip Steak or Top Sirloin dry and season generously with salt and pepper. Heat a pan on high with 2 teaspoons oil, reduce to medium-high, and sear the steaks for 4 minutes per side plus 1 minute per edge. Lower the heat to medium, add 2 tablespoons butter, 3 quartered garlic cloves, and 2 sprigs fresh rosemary or thyme, then spoon the butter over the steaks to infuse them with extra taste.
5-After searing, let the steaks rest for 10 minutes before slicing. This keeps the juices locked in. Finally, assemble the sandwich: Slice 2 loaves of Italian bread lengthwise and hollow out the top half. Spread the roasted garlic butter on the bottom, layer with 5 ounces baby arugula, the sliced steak, 1/2 pound sliced provolone cheese, the caramelized onions, and the herb mayo. Close it up and serve right away for the best experience.
