Step 1: Heat oil in a frying pan over medium-low heat. Add leek and sauté until soft but not brown, 6–8 minutes. Add garlic and cook for a couple of minutes more. Season lightly with salt & pepper and set aside.
Step 2: In a bowl, mix grated cheeses; reserve a few tablespoons for the topping. Stir in cream cheese and leek mixture. Season to taste with salt & pepper.
Step 3: Spread mixture evenly in a baking dish, sprinkle reserved grated cheese on top, and bake in preheated 375 degree oven until bubbling, 15–18 minutes. Set under broiler to lightly brown top. Serve warm.
