Recipe FAQ

What type of sausage works best?

Mild or spicy Italian sausage with casings removed works well to complement the peppers and cheese without overpowering.

How do I prevent the pasta from overcooking during baking?

Cooking the rigatoni just shy of al dente ensures it won't become mushy after baking, maintaining a perfect bite.

Can I add extra vegetables?

Sautéed mushrooms or spinach are great additions for more variety and nutrients without altering the core flavors.

What cheese combination is recommended?

Mozzarella provides melty texture, while Parmesan adds a sharp, nutty depth to the baked dish.

Is there a way to adjust the spice level?

Using hot Italian sausage and increasing red pepper flakes can raise the heat; otherwise, mild sausage keeps it gentle.
