Can I use a different pasta shape?
Yes. Campanelle works well because it holds sauce, but penne, rigatoni, or small shells will work. Avoid long noodles like spaghetti.
Do I need to cook the pasta first?
No. Add uncooked pasta directly to the skillet; the sauce and water will cook it as the dish simmers.
How do I know when it's done?
The pasta should be tender and the liquid mostly absorbed, about 15–20 minutes of simmering. Stir occasionally to prevent sticking.
Can I make this ahead?
Yes. Prepare up to the point of adding cheese, refrigerate, then reheat gently on the stovetop, adding the cheeses at the end.
What if my sauce is too thick?
Add water 1/4 cup at a time during cooking. The pasta needs liquid to cook and soften properly.
