Pasta and Assembly

• 1 lb (450 g) fresh egg pasta sheets (12–15 sheets sized to a 9×13-inch/3-quart dish)
• 2 cups (180 g) finely grated Parmigiano Reggiano
• 1 tbsp unsalted butter, for greasing the baking dish
• 2 tbsp kosher salt for pasta water

Step-by-Step Instructions

Step 1: Build the soffritto and brown the meats

In a heavy pot or Dutch oven over medium heat, warm the olive oil and 2 tbsp butter. Add the pancetta and cook until lightly rendered, 3–4 minutes. Stir in the onion, carrot, and celery with 1/2 tsp of the kosher salt. Cook gently, stirring often, until the vegetables are soft and sweet but not browned, 8–10 minutes. Add the beef and pork, breaking them up with a spoon, and cook until no longer pink and lightly browned in spots, 8–10 minutes. Season with another 1/2 tsp salt and the black pepper.

Step 2: Deglaze, add liquids, and slow-simmer

Pour in the white wine and simmer, scraping up any browned bits, until nearly evaporated, about 2 minutes. Stir in the tomato passata, milk, stock, bay leaf, and remaining 3/4 tsp salt. Bring just to a lazy simmer. Reduce heat to low and cook uncovered for 2 1/2 hours, stirring every 20–30 minutes. The ragù should be thick, glossy, and spoonable; add a splash of stock if it gets too dry. Remove bay leaf and adjust seasoning as needed.

Step 3: Make the besciamella

About 30 minutes before the ragù is done, warm the milk in a saucepan or microwave. In a separate medium saucepan over medium heat, melt the 6 tbsp butter. Whisk in the flour and cook, whisking constantly, for 2 minutes to form a smooth roux without browning. Gradually whisk in the warm milk, a ladleful at a time, whisking until smooth after each addition. Simmer gently, whisking, until the sauce thickens to coat the back of a spoon, 5–7 minutes. Season with salt, white pepper, and nutmeg. Keep warm over very low heat; press parchment or plastic wrap directly onto the surface to prevent a skin if holding.

Step 4: Par-cook the pasta sheets

Bring 6 quarts of water to a boil and season with 2 tbsp kosher salt. Set a large bowl of cool water nearby and line a baking sheet with clean kitchen towels. Working in batches, drop 3–4 fresh pasta sheets into the boiling water and cook 45–60 seconds, just until pliable. Transfer to the cool water, then lay flat on the towels to dry. Repeat with remaining sheets, keeping them in a single layer so they do not stick.

Step 5: Preheat and prep the baking dish

Heat the oven to 375°F (190°C). Grease a 9×13-inch (3-quart) baking dish with 1 tbsp butter. Make sure the ragù and besciamella are warm and spreadable; if needed, splash the ragù with a bit of stock and stir to loosen.

Step 6: Layer the lasagne

Spread 1/2 cup ragù over the bottom of the dish. Add a single layer of pasta (trim to fit as needed). Top with about 1/2 cup ragù and 1/3 cup besciamella, spreading each to the edges. Sprinkle 2–3 tbsp Parmigiano. Repeat these layers 4 more times (pasta, ragù, besciamella, Parmigiano), for a total of 5 pasta layers. Finish with a final layer of pasta, then the remaining besciamella and a generous blanket of Parmigiano. If you like, dot the top with a few small pieces of butter for extra bronzing.

Step 7: Bake until bubbling and bronzed

Tent the dish with foil, lightly oiled on the underside to prevent sticking. Bake for 30 minutes. Remove the foil and bake 10–15 minutes more, until the top is deep golden and the edges are bubbling. For extra color, broil 1–2 minutes, watching closely. Internal temperature should register at least 165°F (74°C).

Step 8: Rest, slice, and serve

Let the lasagne rest for 20 minutes so the layers set. Slice cleanly with a sharp knife and serve with extra Parmigiano at the table.

Pro Tips

• Gentle simmer is key: the ragù should barely bubble. A heat diffuser helps prevent scorching.
• Texture test: a spoon dragged through the ragù should leave a brief trail that slowly fills in.
• Besciamella target: thicker than heavy cream but still pourable; whisk if it thickens as it sits.
• Keep pasta sheets from sticking by laying them in a single layer on towels; a light brush of oil helps if needed.
• Resting 20–30 minutes gives picture-perfect slices and keeps layers intact.

Variations

• Spinach Lasagne Sheets: Use fresh spinach egg pasta for a traditional green lasagne from Emilia-Romagna.
• No-Boil Shortcut: Use dried no-boil sheets and add 1/2 cup extra milk to the besciamella; bake covered 45–50 minutes before uncovering.
• Mushroom Boost: Add 8 oz finely chopped cremini mushrooms to the soffritto; cook until browned before adding the meats for deeper umami.

Storage & Make-Ahead

Ragù can be made up to 4 days ahead or frozen for up to 3 months. Besciamella can be made up to 3 days ahead; rewarm gently with a splash of milk. Assemble the lasagne up to 24 hours in advance, cover, and refrigerate; bake straight from the fridge at 375°F (190°C) for 50–60 minutes, uncovering for the last 10–15 minutes. To freeze assembled (unbaked), wrap well and freeze up to 2 months; bake from frozen at 350°F (175°C) for 60–75 minutes, then uncover and brown. Leftovers keep 3–4 days refrigerated; reheat covered at 350°F (175°C) for 20–25 minutes or microwave individual slices.
