Step-by-Step Instructions
Prepare the Ragù Sauce
Start with the ragù. It needs at least 2 hours to develop deep flavors. Heat olive oil in a large pot over medium heat. Add onion, carrots, and celery. Cook for 8-10 minutes until soft. Stir often. Do not brown them.
Add pancetta. Cook for 5 minutes until fat renders. Crumble in ground beef. Break it up with a wooden spoon. Cook until browned, about 10 minutes. Drain excess fat if needed.
Stir in garlic. Cook for 1 minute. Pour in red wine. Scrape the pot bottom. Simmer until wine reduces by half, about 5 minutes.
Add crushed tomatoes, tomato paste, milk, and bay leaf. Season with salt and pepper. Bring to a gentle simmer. Cover partially. Cook on low heat for 2-3 hours. Stir every 20 minutes. Add water if it thickens too much. The sauce should be thick and flavorful. Remove bay leaf. Taste and adjust seasoning.
Make the Béchamel Sauce
While ragù simmers, prepare béchamel. Melt butter in a saucepan over medium heat. Whisk in flour. Cook for 2 minutes to form a roux. It should turn golden, not brown.
Slowly pour in warm milk, whisking constantly. Prevent lumps. Cook until sauce thickens, 5-7 minutes. It will coat the back of a spoon. Add nutmeg, salt, and white pepper. Remove from heat. Cover with plastic wrap touching the surface to avoid skin.
Assemble the Lasagna
Preheat oven to 180°C (350°F). Grease a 9×13-inch baking dish with butter.
Spread 1 cup ragù on the bottom. Layer 3-4 lasagna sheets to cover. No overlap. Add 1 cup ragù. Spoon 1/3 of béchamel over it. Sprinkle 50g Parmigiano-Reggiano.
Repeat layers: pasta, ragù, béchamel, Parmigiano. Use all ragù and béchamel. Top final pasta layer with remaining béchamel. Scatter mozzarella slices. Finish with generous Parmigiano.
Bake the Lasagna
Cover tightly with foil. Bake for 25 minutes. Remove foil. Bake 20-25 more minutes until top bubbles and browns. If needed, broil for 2 minutes for crisp edges. Watch closely.
Remove from oven. Let rest 15-30 minutes. This sets the layers. Cut into squares. Serve hot.
Tips for Perfect Traditional Lasagna
Use a flavorful red wine like Chianti for the ragù. San Marzano tomatoes give authentic taste. Fresh pasta absorbs sauces better. If using dried, boil briefly in salted water. Drain well.
Let sauces cool slightly before assembly. Hot sauces wilt pasta. Resting after baking prevents soggy slices. Make ahead: assemble, cover, refrigerate up to 24 hours. Bake straight from fridge, adding 10 minutes.
Vegetarian option: swap beef for lentils or mushrooms. Keep ragù simmer long for umami. Freeze unbaked lasagna for up to 3 months. Thaw overnight before baking.
Common mistakes to avoid. Do not skip soffritto (onion, carrot, celery). It builds base flavor. Overcook pasta layers. They continue cooking in oven. Use whole milk in béchamel for creaminess.
Pair with simple green salad and crusty bread. Chianti or Sangiovese wine complements it. Leftovers reheat well in oven or microwave.
History adds charm. Lasagna traces to 14th-century Italy. “Lasagna” means “cooking pot” in old Italian. Modern version from Bologna cookbook in 1880s. Ragù alla Bolognese is protected by Italian academy.
Variations on Traditional Lasagna
Stick to classic for purists. Add spinach for verde lasagna. Seafood version uses shrimp in ragù. Shortcuts: jarred marinara, but homemade shines.
In Phan Rang-Tháp Chàm, source local beef for freshness. Vietnamese markets offer good carrots and celery. Adapt with fish sauce trace if desired, but keep Italian pure.
