Ask About This Recipe

Yes, penne or similar tubular pastas work well due to their shape and cooking time compatibility.

How do I prevent the pasta from sticking?

Greasing the slow cooker and layering ingredients evenly helps prevent sticking during slow cooking.

Can I prepare this dish ahead of time?

You can assemble all ingredients in the slow cooker a few hours in advance and refrigerate until cooking.

What cheese substitutions work well?

Mozzarella, ricotta, and Parmesan create creaminess and flavor, but provolone or fontina can be tasty alternatives.
