Clean the leeks and place them in the steam basket of your pressure cooker with a splash of water.
Heat over high heat and when the casserole whistles, reduce the heat to medium and cook for 10 minutes.
Preheat your oven to 240°C.
Then remove and drain the leeks and place them on a baking tray covered with baking paper.
Drizzle each leek with a drizzle of olive oil and season (salt, pepper, garlic and parmesan).
Bake for 10 to 15 minutes and serve as you wish: as an accompaniment, toast, starter, salad, etc. Enjoy your meal.
