Instructions

Prepare Aioli: In a bowl, combine mayonnaise and freshly minced garlic. Mix well and allow the mixture to rest for at least 30 minutes so the garlic flavor infuses the aioli fully.
Caramelize Onions: Melt butter in a skillet over low heat. Add the thinly sliced onions and cover the pan. Cook gently for about 20 minutes, stirring occasionally to prevent burning.
Develop Onion Flavor: Remove the lid and continue to cook the onions for another 20-30 minutes over low heat until they turn golden brown and jammy. In the last 5 minutes, stir in brown sugar and balsamic vinegar to enhance sweetness and add a tangy depth.
Prepare Steak: Remove the Bavette beef steak from the refrigerator and let it come to room temperature for an even cook. Season both sides generously with salt and pepper.
Sear Steak: Heat vegetable oil in a hot skillet over medium-high heat. Place the steak in the skillet and cook for about 3 minutes on one side, then flip and cook for 2 minutes on the other side for medium-rare doneness. Adjust timing if you prefer different doneness levels.
Rest and Slice Steak: Remove steak from the skillet and let it rest for a few minutes to retain juices. Slice thinly against the grain for tenderness.
Assemble Sandwich: Slice open the Turkish bread pieces lengthwise. Spread a generous layer of the prepared garlic aioli on each side of the bread.
Layer Ingredients: On the bottom half of the bread, place fresh rocket, then slices of tomato, followed by the sliced steak, and top with the caramelized onions. Drizzle mustard over the layered ingredients for an added tangy kick.
Finish and Serve: Close the sandwiches and optionally sprinkle some fresh herbs like parsley or thyme for extra aroma and flavor. Serve immediately while the steak is warm and enjoy.

Notes

Allowing the aioli to sit for 30 minutes enhances the garlic flavor significantly.
Cooking the onions low and slow is key to achieving a sweet, jammy texture.
Letting the steak rest after searing helps keep it juicy.
Slicing the steak against the grain ensures maximum tenderness.
You can substitute the Bavette steak with skirt or flank steak if desired.
Serve with a side of fries or a fresh salad for a complete meal.
