Use fresh garlic for the best flavor. Do not overcook the shrimp—once cooked, they can become rubbery.
Ensure your pan is large enough to hold the pasta and sauce without overcrowding, which can lower the pan's temperature and affect browning or cooking the ingredients properly.
Add a splash of vegetable broth or water if the sauce feels too thick.
For a richer sauce, you can add a splash of cream (optional).
