Nonna Maud's Lasagna

Method

1. 01

   Step 1. Finely chop the celery, carrot and onion and sweat them in a pan for a few minutes with enough olive oil.

2. 02

   Step 2. Add the minced beef, salt and pepper. When the meat is cooked, add the passata (and the basil, if using).

3. 03

   Step 3. Cook for 5, at most 10 minutes from when it starts to simmer, over low to medium-low heat, then turn off and adjust the salt. The sauce must stay fairly liquid so the pasta can cook, but not raw. Turn the oven on now.

4. 04

   Step 4. In a baking dish spread a base of sauce, then build layers of pasta, sauce, parmesan and mozzarella torn by hand, until the dish is full.

5. 05

   Step 5. Bake at 220°C in a preheated static oven for about 25 minutes.
