Leek Gratin with Ham

### Instructions:

#### 1. **Prepare the Leeks:**
– Begin by cleaning the leeks thoroughly to remove any dirt or grit. Trim off the root ends and the tough green tops, leaving only the pale white and light green parts. Slice the leeks into rings or half-moons.
– In a large skillet or sauté pan, melt 1 tablespoon of butter over medium heat. Add the sliced leeks and cook, stirring occasionally, for about 5-7 minutes, until they are softened and slightly caramelized. Remove from heat and set aside.

#### 2. **Make the Creamy Sauce:**
– In the same pan, melt the remaining tablespoon of butter over medium heat. Once melted, add the flour and whisk to form a smooth roux. Cook for about 1-2 minutes to remove the raw flour taste.
– Slowly whisk in the milk and heavy cream, making sure to incorporate the roux into the liquids. Continue whisking until the sauce thickens, about 3-5 minutes. Stir in the Dijon mustard (if using), ground nutmeg, salt, and pepper. Taste and adjust the seasoning as needed.

#### 3. **Assemble the Gratin:**
– Preheat your oven to 375°F (190°C).
– In a large mixing bowl, combine the sautéed leeks, diced ham, and the creamy sauce. Stir until the ingredients are evenly distributed.
– Transfer the mixture to a greased 9×13-inch baking dish or individual gratin dishes.

#### 4. **Add the Topping:**
– Sprinkle the grated Gruyère or Swiss cheese evenly over the top of the leek and ham mixture. If you like a bit of extra crunch, you can also sprinkle breadcrumbs over the cheese for added texture.

#### 5. **Bake the Gratin:**
– Place the baking dish in the preheated oven and bake for 20-25 minutes, or until the top is golden and bubbly. The cheese should be melted and slightly browned, and the sauce should be thick and creamy.

#### 6. **Garnish and Serve:**
– Remove the gratin from the oven and let it cool for a few minutes before serving. Garnish with freshly chopped parsley or chives for a burst of color and freshness.
– Serve this delicious leek gratin with ham as a side dish to roasted meats, or enjoy it as a hearty main course.
