Mix the crushed peppercorns with the olive oil. Pour the mixture on to a dinner plate and rub into both sides of the steaks. Leave to marinate in the fridge for 1 hour.
Heat a frying pan or a griddle until hot and cook the steaks for 2-3 minutes on each side (for rare), or longer on all sides and cooked to your liking. Remove the steaks and set aside in a warm place.
Add the wine, garlic, rosemary, and thyme to the pan and stir well, scraping up any browned bit from the bottom of the pan with a wooden spoon. Simmer for 5 minutes, until the volume of liquid has reduced, and you have a thick sauce and pour over the steaks.
