Steps

1. 1

   Chop the onion into small pieces and sauté in olive oil.

2. 2

   When the onions have browned well, add the 350g of ground beef.

3. 3

   Cook over medium heat then add the bolognese sauce.

4. 4

   Prepare the béchamel sauce. Melt the butter over high heat.

5. 5

   Once melted, add the two tablespoons of flour and stir with a whisk over medium heat.

6. 6

   When the mixture is smooth (very quick), gradually add the milk without stopping whisking to avoid lumps.

7. 7

   Continue stirring until the béchamel thickens.

8. 8

   Mix the previously prepared bolognese sauce with the béchamel.

9. 9

   Then, in a baking dish, pour a layer of this mixture and cover with lasagna noodles. Repeat the process until the sauce is used up (about 2 times).

10. 10

    The last layer must be a layer of sauce. Add the grated Gruyère cheese and bake for about 45 minutes at 180°C (gas mark 6).

11. 11

    To check if the lasagna is cooked, pierce with a knife; the pasta should be tender, so the knife should slide in without any problem.
