Pane Frattau-Inspired Dish (Layers, Tomato, Egg Optional)

Sardinian Lasagna

Pane frattau is what happens when Sardinians want lasagna but don’t have time to make pasta. It uses the same logic—layers, sauce, cheese—but replaces the pasta sheets with pane carasau, the island’s iconic crisp flatbread.

The result is rustic, comforting, and deeply satisfying. The bread softens from the sauce and broth, creating layers that are simultaneously tender and slightly chewy. The poached egg on top is traditional—when you break the yolk, it creates a rich sauce that ties everything together.

The “Nothing Wasted” Philosophy

This dish embodies a core Mediterranean principle: use everything. Pane carasau was designed to last for weeks, but eventually it would soften or break. Rather than throw it away, Sardinians created dishes like this one and zuppa gallurese to transform old bread into new meals.

In my grandmother’s house, nothing was wasted. Stale bread became breadcrumbs, bread soup, or pane frattau. This wasn’t about poverty—it was about respect for the food and the labor that produced it.

The Egg: Optional but Traditional

The poached egg on top is what makes pane frattau a complete meal. The runny yolk mingles with the tomato sauce and creates a creamy, rich finish.

If you’re avoiding eggs:

• Skip it entirely—the dish is still satisfying
• Add a dollop of ricotta or labneh instead
• Use a soft-scrambled egg folded into the layers

If you’re nervous about poaching:

• Use a fried egg with a runny yolk instead
• Try the “swirl method” (create a whirlpool in the water before adding the egg)
• Use an egg poacher or silicone cups

Building the Dish: Two Approaches

Individual Portions: Soften one sheet of bread, place on a plate, add sauce and cheese, repeat for 2-3 layers, top with egg. This is the restaurant-style presentation.

Family Style: Build one large stack on a serving platter, then cut into wedges like a lasagna. Top with all four poached eggs. This is the home-style approach.

Both are correct. Choose based on your occasion.

Variations

With Meat: Add crumbled cooked sausage or pancetta between the layers for a heartier version.

With Vegetables: Sautéed spinach or chard can be added between layers for extra vegetables.

Spicy: Add red pepper flakes to the tomato sauce for heat.

With Broth (More Traditional): Some versions pour hot broth over the assembled dish just before serving, making it more soup-like. Try this if you want a softer, more comforting texture.

Without Egg (Vegan): Skip the egg and use more pecorino or a plant-based cheese alternative. Add a drizzle of good olive oil at the end.

A Note on Authenticity

“Pane frattau” means “broken bread” in Sardinian, referring to the practice of using broken pieces of pane carasau rather than whole sheets. In traditional preparations, you’d use the fragments left at the bottom of the bread basket.

This version uses whole sheets because they’re easier to work with and create neater layers. But if you have broken pieces, use them—the dish will be more rustic and just as delicious.
