Common recipe questions

Can I use different pasta types?

Layering sauce and cheeses evenly and adding water helps keep pasta moist and prevents sticking during slow cooking.

Can I add vegetables or meat?

Absolutely. Sautéed vegetables or browned sausage enhance flavor and add texture to the dish.

What cheese combinations work best?

Ricotta, mozzarella, and Parmesan provide a creamy, melty, and flavorful balance that enriches the dish.

How long should the dish rest before serving?

Letting it rest uncovered for 10 minutes allows the layers to settle and enhances flavor melding.
