If you want to pre-cook the pasta, heat water in a wide saucepan - cook 3-4 pasta sheets at a time - as much as needed for one layer. I cook them for a maximum of 3 minutes.
1 package pasta
Spread some of the béchamel sauce in the baking dish.
Layer the pasta sheets over the sauce.
Spread béchamel over the pasta.
Layer about half of the meat sauce, and sprinkle grated cheese on top.
200 g cheese
Arrange a second layer of pasta and spread béchamel over it.
Layer the rest of the meat sauce and sprinkle cheese over it.
Arrange a third layer of pasta, spread béchamel over it, and finally sprinkle with grated cheese.
Place the lasagna in an oven preheated to 200 degrees (top/bottom mode) and bake for about 35-40 minutes.
After baking, divide into portions and serve hot.

When dividing the lasagna into 4 portions, one portion has approximately 770 calories.And here's another tip from me - if you pre-cook the pasta.As I wrote, I cook it for about 3 minutes - I take it out and arrange it in the dish, put the next 3-4 sheets to cook, and in the meantime, I spread the sauces on the pasta I took out earlier. When I finish with the sauces, I take out the cooking pasta, arrange it, put the next portion of pasta into the pot, and deal with the sauces. This way everything goes smoothly :)
