Answers to Recipe Questions

How do I prevent the pasta from sticking in the slow cooker?

Lightly grease the slow cooker before layering ingredients and ensure the pasta is evenly coated with sauce and water to avoid sticking.

Is it possible to prepare this dish gluten-free?

Absolutely, swapping regular pasta for gluten-free varieties keeps it accessible without compromising texture.

What cheeses blend best for this dish?

A combination of ricotta, mozzarella, and Parmesan offers a creamy, melty, and flavorful cheese profile ideal for slow baking.

How long should the baked ziti rest after slow cooking?

Allow the dish to sit uncovered for about 10 minutes after cooking to let it set and enhance flavor melding.
