👨‍🍳 Method

For the Béchamel

1. 1
   Melt the butter in a pot over medium heat, add the flour and stir 1–2 minutes, until a smooth roux forms and starts to bubble.

2. 2
   Gradually add the milk, whisking constantly, and cook 5–8 minutes, until the sauce is thick and coats the back of a spoon.

   StoveWhisk

   💡Add the milk slowly, whisking constantly, so no lumps form. For lasagna, the common ratio is about 7 g flour per 100 ml milk (4 tablespoons flour to 2 cups): more flour gives a thick béchamel, for moussaka; less flour gives a soft béchamel, for a sauce.
3. 3
   Season with salt, Nutmeg and black pepper.

To assemble

1. 4
   Preheat the oven to 200°C (390°F).

   ⚙ Preheating the OvenOven

   💡Put things in the oven only once it's reached temperature, after the heating light has gone off: an oven that hasn't reached temperature changes baking times, and the bake burns outside or stays underbaked.
2. 5
   Spread the butter on the bread slices.
3. 6
   Spread béchamel on half of the bread slices and top with the turkey breast and yellow cheese.
4. 7
   Close each sandwich with another slice of bread and toast in a pan over medium heat for 2–3 minutes per side, until the bread is golden. Transfer the sandwiches to a baking sheet lined with parchment paper.

5. 8
   Spread the rest of the béchamel over the sandwiches and sprinkle the Parmesan over it.

   💡The béchamel on top of the sandwich keeps the bread from drying out in the oven, and the grated cheese on it browns into a crust.
6. 9
   Bake 5 minutes, until the topping is golden and bubbling.

   💡Check by the cue (until…), not just the clock: every oven bakes a little differently.
