Preheat the oven to 200°C conventional (180°C fan-forced). Line a tray with baking paper.
Rub the beef with the olive oil and season well. Heat a non-stick frying pan over medium–high heat. Sear the beef for 2 minutes each side and place in the oven for 15 minutes for rare or 20 minutes for medium rare (you may have to adjust timings depending on the shape of your beef). Remove from the oven, cover with foil and let it rest. Slice into thin pieces and set aside.
300 g beef, 1 tablespoon extra virgin olive oil, sea salt & cracked black pepper
Place your baguette slices on the prepared tray. Use olive oil spray or a pastry brush with olive oil and spray or rub the baguette with oil. Season well. Bake for about 13 minutes or until just turning golden. Remove and let cool.
