Lasagna with Ham and Cheese (Print Version)

# Ingredients:

→ Pasta & Ham

01 - 6 large sheets fresh lasagna pasta
02 - 6 slices cooked ham

→ Mornay Sauce

03 - 50 grams onion, peeled and quartered
04 - 50 grams unsalted butter
05 - 55 grams plain flour
06 - 600 grams semi-skimmed milk
07 - 1 egg yolk
08 - 0.5 teaspoon fine salt
09 - 3 pinches ground black pepper
10 - 3 pinches ground nutmeg

→ Cheese

11 - 140 grams grated Emmental cheese
12 - 220 grams sliced raclette cheese or comparable melting cheese

# Instructions:

01 - Place the peeled and quartered onion in a blender. Blend for 2 seconds at speed 5, then scrape down the sides with a spatula.
02 - Add butter, flour, milk, egg yolk, salt, pepper, and nutmeg to the blender. Cook for 8 minutes at 90°C on speed 4 until smooth and thickened.
03 - Add 100 grams of grated Emmental cheese to the sauce and cook for an additional minute at 90°C on speed 4 until fully melted.
04 - Butter a large gratin dish. Spread a thin layer of Mornay sauce on the bottom to prevent sticking.
05 - Place a layer of lasagna sheets in the dish, trimming as needed. Spread one quarter of the Mornay sauce over the pasta, followed by 2 slices of ham and one third of the sliced raclette cheese.
06 - Add a second layer of pasta. Top with one third of the remaining sauce, 2 slices of ham, and more raclette cheese. Repeat for a third layer: pasta, half the remaining sauce, 2 slices of ham, and the last of the raclette cheese.
07 - Finish with a final layer of lasagna sheets. Spread the remaining Mornay sauce on top and sprinkle with 40 grams of grated Emmental cheese.
08 - Preheat the oven to 200°C. Bake for 20 minutes until the surface is golden brown and bubbling.

# Notes:

01 - Allow the lasagna to rest for a few minutes after baking to improve slicing and structure.
