To help you see where the noodles are, run your finger along the edges of the noodles to create a rough outline in the foil.
- 5
Fold the top and bottom flaps of foil over, creasing and pressing flat.
- 6
Flip the foil sheet onto the table so that it’s now standing, then arrange into a square box, using the 4 groups of noodles as a visual guide.

Fold and crease over any excess foil to join the ends together, then set aside.

Slowly drizzle in the milk and bring to a boil, whisking constantly until smooth.
- 11
Mix in salt, pepper, and nutmeg.

Transfer the béchamel to a large bowl and press plastic wrap onto the surface of the sauce to prevent a skin from forming.
- 14
Set aside.
- 15
Heat oil in a very large pot over high heat.
- 16
Once the oil begins to shimmer, add the onions, carrots, and celery and cook until the vegetables have started to sweat but aren’t browning.
- 17
Add in the ground beef and use a wooden spoon or spatula to break up the meat into small pieces.
- 18
Cook the beef, stirring occasionally, until half of the liquid has evaporated.

To assemble, line a greased 9x9-inch (23x23-cm) square baking pan with 2 sheets of foil that extend over the sides.
- 23
Spread a thin layer of béchamel on the lined baking pan and top with 2 lasagna noodles.
- 24
Spread a thin layer of meat sauce evenly across the noodles, followed by a thin layer of béchamel.
- 25
Repeat the layering process, following the order of: 2 noodles, meat sauce, and béchamel.
- 26
Alternate the direction of the lasagna sheets after every layer.
- 27
After 50 layers, place the foil box over the lasagna, helping it stay upright and stable.
- 28
Continue with the layering process until the 99th layer.
- 29
Sprinkle Parmesan on top, then cover the whole lasagna with foil.
- 30
Bake for about 1½ hours, uncovering the foil halfway, until the top is a deep golden brown.
