Instructions

1. Temper the meat

   Remove the flank steak from the refrigerator and let it sit at room temperature for 15 minutes so it cooks evenly.

   Time: PT15M

2. Prepare the garlic butter

   Mix the softened butter with the two finely chopped garlic cloves, form a ball, wrap it in plastic wrap and place it in the freezer (or refrigerator) for 5 minutes.

   Time: PT5M

3. Grate the cheeses

   Grate the Bleu d'Auvergne, Camembert, and Cheddar separately. Set each cheese aside in a small separate bowl.

   Time: PT10M

4. Trim and debone the flank steak

   On the board, using a boning knife, remove the outer fat, nerves, and the thin silvery membrane following the grain of the muscle. Set the deboned meat aside.

   Time: PT10M

5. Slice the meat

   Cut the flank steak in half lengthwise, then slice thinly (about 3 mm) against the grain to obtain tender strips.

   Time: PT5M

6. Prepare the bread

   Cut each piece of bread in half, spread the garlic butter generously on both sides. Set aside.

   Time: PT5M

7. Make the three‑cheese sauce

   Melt 1 tbsp butter in a saucepan over low heat, add the cream, season lightly with salt. Gradually stir in the blue cheese, then the soft cheese, and finally the red cheese, stirring constantly until a smooth, homogeneous sauce is achieved.

   Time: PT3M

   Temperature: 80°C

8. Grill the bread

   Heat the pan over medium‑high heat (≈180°C). Place the bread slices, garlic‑butter side down, and grill 1 minute per side until golden and crispy.

   Time: PT2M

   Temperature: 180°C

9. Sear the flank steak strips

   Add a drizzle of olive oil to the pan, heat over high heat (≈220°C). Sauté the meat strips 2 minutes per side, until browned on the outside but still pink inside. Deglaze with cognac if desired, then remove from heat.

   Time: PT4M

   Temperature: 220°C

10. Assemble the sandwich

    On the bottom half of the bread, arrange the flank steak strips, generously drizzle with the three‑cheese sauce, top with the upper half. Serve immediately.
