If you love crusted dishes from meat to fish, and even cheese, which is also loved by vegetarians, you will be incredibly surprised. We are talking about the beef fillet in crust, with an original coating compared to the puff pastry or bread. For this version, we chose a delightful coating with a typically Mediterranean character thanks to Greek olives and pistachios. Thanks to these flavors, the beef fillet in crust will be the perfect dish for lovers of second courses with a bold taste, ideal for festive lunches or special occasions.
To prepare the beef fillet in crust, start with the crust. Place the pitted olives together with the pistachios on the cutting board 1, then use a smooth-bladed knife to chop them coarsely 2. Gather the mixture in a bowl and add grated Grana Padano 3,
then mix 4 to evenly combine everything and set aside for a moment 5. In the meantime, peel the red onion and slice it to a 1/8-inch thickness 6.
Now that everything is ready, sprinkle the cutting board, or work surface, with salt and pepper 7, then place the beef fillet on top. Rotate it, gently massaging the meat, so that the spices penetrate the tissues 8. Move to the stove and place a pan over the heat, let the butter melt and season with sage, rosemary, and a garlic clove 9.
Add the oil as well 10, and when the base is sufficiently hot, place the fillet in the pan 11. Allow the meat to seal, at medium-high temperature, for about 3 minutes per side 12.
Occasionally, baste the surface to keep the meat moist 13. When the fillet is completely cooked, discard the aromatic herbs and garlic 14 and place the piece of meat on a rack with a tray underneath 15.
Spread the olive and pistachio mixture on the surface 16 and press it to adhere completely to the meat 17. Finish cooking in the oven 18.
Bake at 430°F in a preheated static oven for about 12 minutes 19. Meanwhile, deglaze the seasoning in the pan. If necessary, add a splash of water to dilute the seasoning, then add the onions 20 and red wine. Cook at medium temperature for about 8 minutes 21.
Occasionally stir 22, and when the liquid is reduced by half, add the mustard 23. Continue stirring for a few more moments and then turn off the heat 24.
Transfer the mixture to the blender and blend 25 to obtain a smooth puree 26. Once the fillet is cooked, let it cool slightly before slicing and serving it with the sauce. The beef fillet in crust is ready 27!
