Instructions

  1. 1

    Bring the steaks to room temperature by letting them sit out for 30 minutes to an hour, depending on the air temperature. This ensures a more even cook.

  2. 2

    Just before cooking, generously season both sides of the steaks with salt and pepper.

  3. 3

    Heat 1 tablespoon of vegetable oil in a heavy-based frying pan over high heat until it just begins to smoke.

  4. 4

    Carefully place the steaks in the hot pan. Cook each side for about 2 minutes to achieve a perfect medium-rare doneness. Refer to Note 1 for a guide to other doneness levels.

  5. 5

    Remove the steaks from the pan and place them on a plate. Cover them loosely with foil and let them rest for 5 to 10 minutes. This resting period is crucial for a juicy steak.

  6. 6

    While the steaks are resting, return the same pan to the stove over medium-high heat with the remaining 1 tablespoon of oil.

  7. 7

    Add the sliced bell peppers and cook, stirring occasionally, until they are nicely charred and tender. Remove the pan from the heat.

  8. 8

    Serve the rested steaks topped with the charred bell peppers, with a side of pesto and warm flatbreads.

Recipe Notes

  • Steak cooking times – These times are for 10 oz / 300g boneless steaks, about 2.5 cm / 1 inch thick, that have been brought to room temperature. If your steaks are cold, add about 15 seconds per side. Here is a general guide for other levels of doneness: Blue: about 1 minute 15 seconds per side; Rare: about 1 minute 30 seconds per side; Medium-rare: about 2 minutes per side; Medium: about 2 minutes 15 seconds per side.

  • Homemade Basil Pesto – For the best flavor, make your own pesto! Simply combine 2 cups of packed fresh basil leaves, 1 garlic clove, 1/4 cup of pine nuts (or cashews, Brazil nuts, walnuts, or almonds), 2/3 cup of extra virgin olive oil, 1/2 cup of grated Parmesan cheese (or Pecorino), 1/4 teaspoon of salt and pepper, and 1/2 to 1 tablespoon of lemon juice in a small food processor. Whiz until combined. You can also use a mortar and pestle for a more rustic texture.
