One of the biggest complaints I get concerning Aglio Olio is that it is bland. There are several possible reasons. First, be sure to use fresh pasta. If your pasta is even a day or two old, it will significantly change the taste of your dish.  Second, be sure to use good-quality olive oil. The better the olive oil, the more flavorful your Aglio olio will be.  Make sure you are using fresh garlic. Old or stored garlic can lose its flavor and become less pungent.  Be careful not to overcook the garlic. Once it starts to brown, it will become bitter. The best way to avoid this is to add the garlic towards the end of the cooking process. One of the biggest complaints I get concerning Aglio Olio is that it is bland.
