Kitchen Tips & Answers

Can I use penne instead of ziti?

Yes, penne works well as it holds sauce similarly and cooks evenly in the slow cooker.

How do I prevent the pasta from sticking?

Lightly greasing the slow cooker before layering and adding enough water helps keep the pasta from sticking.

Can I prepare this ahead of time?

You can assemble the layers a few hours before cooking and refrigerate, then cook when ready.

What cheese substitutions can I make?

Ricotta can be replaced with cottage cheese, and a blend of mozzarella and Parmesan adds richness.

Is it possible to add vegetables?

Yes, sautéed vegetables like bell peppers or spinach can be layered in for extra flavor and nutrition.
