Steam and prepare the endive
Melt a knob of butter in a pan with about 3 cm of water. Add the washed endive spears, season with salt, pepper, and a pinch of nutmeg. Cover and cook until tender, testing with a fork. Remove the endive from the pan and let drain well on paper towels. Press lightly if needed to remove excess moisture.
Make the cheese sauce
Melt the butter in a pan, add the flour, and cook briefly until slightly crumbly. Continue stirring while gradually adding the milk until the sauce is smooth and thick. Season with salt, pepper, and nutmeg. Remove the pan from the heat and stir in the grated cheese and Parmesan shavings until melted.
Make the rolls
Roll each endive spear in a slice of ham and arrange the rolls neatly in a baking dish. Pour the cheese sauce over the rolls so they are just covered. Optionally, sprinkle extra cheese on top.
Oven and gratinate
Preheat the oven to 220 °C. Bake the dish for about 15 minutes until the sauce is bubbling and the top is nicely golden brown.
Prepare the potatoes
Cook the potatoes in salted water until tender. Drain and serve alongside the ham-wrapped endive rolls. Finish with some finely chopped parsley.
Tips
- Let the endive drain well after cooking so the sauce doesn’t become watery.
- Gently warm the milk for the sauce before adding it to prevent lumps.
- Use a mix of cheeses (e.g., Gruyère + Parmesan) for extra flavor in the cheese sauce.
- Sprinkle extra Parmesan on top for a deeper gratin color and taste.
- Serve with a simple green salad or boiled potatoes to keep the dish light.
