Baked Leeks With Bechamel and Jamon Serrano: A Culinary Embrace

The first time I tasted leeks prepared this way, it was in a small, sun-drenched tapas bar in Madrid. The earthy sweetness of the leeks, the creamy embrace of the béchamel, and the salty, melt-in-your-mouth decadence of the Jamon Serrano created an unexpectedly perfect symphony of flavors. It was a dish that spoke of simple ingredients elevated to something truly special, a dish that I knew I had to recreate and share.

Instructions

Begin by preparing the leeks. Cut off the roots and the dark green part of the leeks, as these can be quite tough.
Cut the leeks downwards in a cross shape from the top (white part only) to about halfway down. This will allow you to more easily remove any dirt trapped between the layers.
Carefully remove the outer leaves and wash the leeks in plenty of cold water to remove any soil or grit from between the layers. Pay special attention to cleaning the inner layers.
Cut the cleaned leeks into regular, bite-sized pieces.
Bring a large pot of salted water to a boil. Add the cut leeks and cook for about 10 minutes, or until they are tender but not mushy.
Drain the leeks thoroughly in a colander, pressing gently to remove excess water. Set aside.
Now, prepare the béchamel sauce. In a saucepan, heat the olive oil over medium heat.
Add the flour to the heated olive oil and cook gently, stirring constantly with a whisk, for about 2-3 minutes. This creates a roux, which is the base for the sauce. Be careful not to brown the flour too much.
In a separate saucepan, bring the milk to a simmer.
Gradually pour the warm milk into the roux, whisking continuously to prevent lumps from forming.
Continue to cook the béchamel sauce over medium-low heat, stirring constantly, until it thickens to a smooth, creamy consistency. This should take about 5 minutes.
Season the béchamel sauce with salt, pepper, and a pinch of nutmeg to taste.
Cook for another 5 minutes, stirring constantly, to ensure the sauce is smooth and the flour is fully cooked out.
Remove the béchamel sauce from the heat and stir in half of the butter (1 ounce), until it is completely melted and incorporated.
Arrange the cooked leeks in an oven-proof dish, leaving some spaces between them. This allows the béchamel sauce to penetrate and coat the leeks evenly.
Pour the prepared béchamel sauce evenly over the leeks, ensuring they are well coated.
Top the béchamel-covered leeks with the remaining butter (1 ounce), cut into small pieces. This will add richness and help the top brown nicely.
Sprinkle the grated cheese evenly over the top of the dish.
Preheat your oven to 375°F (190°C).
Place the dish under a broiler until the cheese has melted and is lightly browned
Remove the dish from the oven. Arrange the thin slices of Jamon Serrano (or Iberico ham) between the leeks, allowing the heat of the dish to gently melt the fat of the ham and release its savory flavor.
Serve the dish immediately, while it is hot and the Jamon Serrano is still glistening.

Expert Tips & Tricks

Leek Cleaning: Thoroughly cleaning the leeks is crucial, as they tend to trap dirt. Soaking them in cold water after slicing can help release any remaining grit.
Béchamel Consistency: The consistency of the béchamel sauce is key. If it’s too thick, add a little more milk. If it’s too thin, continue cooking it for a few more minutes, stirring constantly.
Cheese Choice: Gruyere or Manchego cheese work well, but you can experiment with other cheeses like Parmesan or Comté for different flavor profiles.
Ham Placement: Don’t overcrowd the leeks with ham. Leaving space allows the flavors to meld and the fat to render properly.

Serving & Storage Suggestions

Serve the Baked Leeks with Bechamel and Jamon Serrano immediately as a warm appetizer, a side dish, or even a light main course. It pairs wonderfully with a crisp white wine or a dry sherry.

Leftovers can be stored in an airtight container in the refrigerator for up to 3 days. To reheat, bake in a preheated oven at 350°F (175°C) until heated through, or microwave in short intervals, stirring occasionally. The texture of the béchamel may change slightly upon reheating.
