  • Add minced garlic and sauté for 1–2 minutes until fragrant.

Notes

Use freshly grated Parmesan for the smoothest, best-flavored sauce.
Add grilled chicken, shrimp, or spinach for protein or extra flavor.
Reheat leftovers with a splash of milk or cream to loosen the sauce.
Can be made vegetarian by skipping meat add-ins.
