Modo de preparo

1. 1

   Prepare the Ragu Bolognese: Heat the olive oil and butter in a large, heavy-bottomed pot over medium heat until melted and hot. Add the ground lamb, pork, veal, and chicken livers if using, breaking up the meat with a wooden spoon. Brown the meat well for about 10 minutes. Add finely chopped onion, carrots, celery, garlic, and sage, cooking until vegetables soften, about 10 minutes. Stir in red pepper flakes if desired.

2. 2

   Add liquids and simmer: Pour in the crushed San Marzano tomatoes, red wine, milk, stock, bay leaves, and fish sauce. Stir to combine, bring to a gentle simmer.

3. 3

   Slow cook the sauce: Reduce heat to very low and simmer the sauce, partially covered, stirring occasionally, for 3 to 4 hours until thickened and flavors meld. Near the end, stir in heavy cream, season with salt and freshly ground black pepper, and remove bay leaves. Stir in minced basil or parsley.

4. 4

   Make the Ricotta Mixture: In a bowl, combine whole-milk ricotta, eggs, minced basil or parsley, and season well with salt and freshly ground black pepper. Mix until smooth and well blended.

5. 5

   Prepare the Besciamella Sauce: In a saucepan, melt butter over medium heat. Add garlic and sauté briefly until fragrant. Stir in flour and cook for about 1-2 minutes to form a roux, stirring constantly. Gradually whisk in whole milk, continuing to whisk until sauce thickens and is smooth. Remove from heat and stir in grated mozzarella cheese, nutmeg, and salt and black pepper to taste.

6. 6

   Preheat the oven: Preheat your oven to 375°F (190°C).

7. 7

   Assemble the lasagna: In a large rectangular baking dish, spread a thin layer of the Ragu Bolognese on the bottom. Place a layer of pasta sheets evenly over the sauce. Spread a portion of the ricotta mixture over the pasta, then spoon on more ragu, then spread some besciamella sauce, and sprinkle with grated Parmesan cheese. Repeat layering until all ingredients are used, finishing with a top layer of pasta covered with besciamella and generous Parmesan cheese and minced basil or parsley.

8. 8

   Bake the lasagna: Cover the assembled lasagna with foil and bake in the preheated oven for 40 minutes. Remove the foil and bake for an additional 15-20 minutes until the top is golden and bubbling.

9. 9

   Rest and serve: Let the lasagna rest for about 15 minutes before slicing to allow the layers to set. Garnish with additional fresh herbs if desired and serve warm.
