Can I substitute paccheri with another pasta?
Yes. Rigatoni, penne rigate, or large shells work well and hold the creamy sauce similarly, though paccheri's large surface area is ideal for capturing the sauce.
Should I use canned or fresh cherry tomatoes?
Either works. Canned cherry tomatoes (as in this recipe) provide consistency year-round; fresh cherry tomatoes add brightness when in season. Adjust cooking time accordingly.
How do I get a creamy sauce without heavy cream?
The sauce relies on emulsifying pasta starch with olive oil and cheese. Reserve pasta water, cook the tomatoes down slightly, then toss the hot pasta with finishing olive oil and grated Parmigiano-Reggiano to create a silky, creamy coating.
Can this be made ahead?
Prepare the tomato sauce ahead and store refrigerated up to 2 days. Cook the pasta fresh and toss with the reheated sauce, finishing olive oil, and cheese just before serving.
Is this dish vegetarian?
Yes. All ingredients are plant-based or dairy (Parmigiano-Reggiano), making it vegetarian-friendly.
