A comforting and flavorful dish featuring tender leeks baked in a creamy, cheesy sauce.
Preheat your oven to 180°C (Gas 4).
Preheating the oven ensures even cooking and a perfect cheesy topping.
Melt the butter in a frying pan over medium heat.
Use unsalted butter to control the saltiness of the dish.
Add the sliced leeks, shallots, and thyme to the pan and sauté until softened.
Cook the leeks slowly to bring out their natural sweetness.
Pour in the white wine and let it simmer until reduced by half.
Reducing the wine concentrates its flavor, adding depth to the dish.
Stir in the cream and season with salt and pepper. Simmer for 5 minutes.
Taste the sauce and adjust the seasoning to your preference.
Transfer the mixture to an ovenproof dish and spread evenly.
Ensure the mixture is evenly distributed for consistent baking.
Sprinkle the grated cheddar cheese over the top.
For a golden crust, use a mix of cheddar and Parmesan cheese.
Bake in the preheated oven for 20-25 minutes, until the cheese is bubbly and golden.
Keep an eye on the dish towards the end of baking to avoid over-browning.
Remove from the oven and let it cool slightly before serving.
Allowing the dish to cool slightly helps the flavors to meld together.
