Note
1: Make your spice mix: In a bowl, add all the ingredients and stir until fully combined.
2: Preheat your oven to 107 °C.
If cooking with an Ooni, use the infrared thermometer to quickly and accurately check the temperature of the pizza stone.
3: Season your beef with the spice blend until fully coated on all sides – you want a strong crust!
4: Place the beef on the grill rack in your roasting pan.
Carefully place it in the oven.

5: Roast until the meat reaches an internal temperature of 52 °C, about 75 to 90 minutes.
For accuracy, use an instant-read thermometer.
6: Using your gloves, remove the steak from the oven and let the meat rest for 15 to 20 minutes.
7: After it’s rested, preheat a cast-iron skillet over medium-high heat.
Add 1 tablespoon (12.5 grams) of olive oil to the skillet.
8: Sear each side of the filet for about 2 to 3 minutes per side, turning the steak over with tongs.
9: Remove the steak from the skillet and serve immediately.
