🍝 Lasagna alla Bolognese
Lasagne alla Bolognese
Lasagna alla Bolognese layers delicate green spinach pasta sheets with rich ragù and silky béchamel — the true, Bologna-born ancestor of the baked pasta dish known worldwide.
Unlike the tomato-and-ricotta-heavy versions found abroad, authentic Bolognese lasagna uses thin sheets of fresh pasta (traditionally colored green with spinach), layered with the same slow-cooked ragù used for tagliatelle, bound together with a delicate béchamel rather than ricotta.
Ingredients
Equipment: Large baking dish, Saucepan for béchamel, Whisk, Large pot for blanching pasta
- 1 batch Ragù alla Bolognese (as in ITA029, doubled for layering)
- 12–15 sheets fresh lasagna pasta (spinach-green traditional, or plain)
Béchamel
- 80 g (⅓ cup) butter
- 80 g (⅔ cup) all-purpose flour
- 1 L (4 cups) whole milk, warmed
- ¼ tsp freshly grated nutmeg
- Salt and white pepper, to taste
Assembly
- 150 g (2 cups) grated Parmigiano-Reggiano
Method
- Prepare the béchamel: melt the butter in a saucepan, whisk in the flour, and cook for 1–2 minutes to form a roux.
- Gradually whisk in the warm milk, a little at a time, until fully smooth. Simmer, stirring constantly, for 8–10 minutes until thickened. Season with nutmeg, salt, and white pepper.
- If using fresh (unbaked) pasta sheets, briefly blanch each in salted boiling water for 30 seconds, then lay flat on a towel — this step can be skipped with fresh no-boil sheets.
- Preheat the oven to 190°C (375°F).
- Spread a thin layer of ragù on the base of a baking dish, followed by a layer of pasta sheets.
- Spread a layer of béchamel over the pasta, then a layer of ragù, then a scatter of Parmigiano. Repeat the layering — pasta, béchamel, ragù, cheese — until you have 5–6 layers, finishing with a generous layer of béchamel and Parmigiano on top.
- Bake for 35–40 minutes until bubbling and golden on top.
- Rest for 10–15 minutes before slicing — this allows the layers to set for clean portions.
Chef Tips
- Resting the baked lasagna before cutting is essential — slicing immediately causes the layers to slide apart.
- Thin, delicate pasta sheets are traditional in Bologna — thick, chewy sheets are a departure from the authentic style.
- Make the ragù and béchamel a day ahead to streamline assembly day.
Common Mistakes to Avoid
- Using ricotta instead of béchamel — this is a distinctly non-Bolognese substitution common in other regional and international styles.
- Skipping the rest time after baking, resulting in a lasagna that falls apart when sliced.
- Making the béchamel too thick or too thin — it should be pourable but coat the back of a spoon.

The oldest known lasagna recipe in Italian dates to a 14th-century manuscript, though the Bolognese ragù-and-béchamel version as known today solidified in the 19th and 20th centuries.
