Ingredients:
- 1 lb lean ground beef
- 0.5 lb ground pork
- 1 large yellow onion, finely minced
- 2 carrots, finely minced
- 2 celery stalks, finely minced
- 2 tbsp extra virgin olive oil
- 2 tbsp tomato paste
- 0.5 cup dry white wine
- 1 cup whole milk (for ragù)
- 28 oz crushed San Marzano tomatoes
- 1 tsp salt
- 0.5 tsp black pepper
- 0.25 tsp ground nutmeg
- 4 tbsp unsalted butter
- 0.5 cup all-purpose flour
- 4 cups whole milk (for béchamel)
- 1 lb dried lasagna sheets
- 2 cups freshly grated Parmigiano-Reggiano cheese
Instructions:
- Sauté the minced onion, carrot, and celery in olive oil over medium heat for 8 minutes until soft. Add the ground beef and pork, browning thoroughly until a crust forms on the bottom of the pot.
- Stir in tomato paste and cook for 2 minutes. Deglaze the pan with wine. Once evaporated, add 1 cup of milk and simmer until absorbed. Stir in crushed tomatoes, salt, pepper, and nutmeg. Simmer on low for 45 minutes.
- In a separate saucepan, melt butter and whisk in flour. Cook for 2 minutes without browning. Gradually whisk in 4 cups of warm milk until thickened. Season with salt and nutmeg to finish the béchamel.
- Spread a thin layer of ragù in a 9x13 inch baking pan. Layer pasta sheets, ragù, béchamel, and Parmigiano-Reggiano. Repeat for 4-5 layers, finishing with a generous layer of béchamel and cheese.
- Cover with foil and bake at 375°F (190°C) for 25 minutes. Remove foil and bake for another 15-20 minutes until the top is bubbling and golden brown.
- Remove from oven and let the lasagna rest for 20 minutes before slicing to allow the layers to set.
