Directions:
For the Steak: Pre heat oven to 400 degrees, clean tenderloin of any silver skin and coat in black pepper and season with salt. Heat oil in a large sauté pan, and sear beef until golden brown on all sides. Cook in oven until medium rare, remove and hold.
For the Aioli: Render bacon in a medium sauté pan, drain and reserve fat and allow to cool, discard bacon. In a kitchen aide mixer with the whisk attachment, place the eggs, mustard and vinegar, slowly add bacon fat until thick, season with salt and pepper and reserve.
For the Mornay: Place butter in a sauté pan and melt. Add flour to form a roux. Then, add milk and boil until thick. Add cheese and turn off heat. Stir to combine and season with salt and pepper, the sauce should be thick.
For the Sautéed Onions: In a medium sauté pan, heat oil and add onions, thyme and garlic and caramelize. Once onions become brown and soft, deglaze with beef stock (adding 1/2 cup at a time), allow to reduce and adjust seasoning with salt and pepper.
For the Pistou: Place all ingredients into a food processor and slow stream in olive oil until it becomes creamy, adjust seasoning.
To Plate: Remove ends of bread and slice lengthwise. Spread butter on bread and grill both sides. Spread 2 tablespoons of bacon aioli on each side of the bread. From the bottom up, build the sandwich: 4 slices of steak then caramelized onions, mornay sauce, 1 cup arugula, 2 tablespoons pistou and top with bread.
