A simple pasta sauce made with just onions, olive oil, and water. The process involves extended simmering, similar to caramelizing onions, resulting in a versatile base for many other recipes. It pairs well with both fresh egg pasta and dry pasta.
To make this pasta sauce, begin by stirring the onions in olive oil. Once combined, cover the onions with water and bring to a simmer. Continue to stir periodically, adding more water as needed to keep the onions covered, and allow the mixture to simmer. Repeat the stir-cover-simmer process over an extended period; the longer it simmers, the better the flavor will develop. This process is similar to caramelizing onions and might take a while, but it's largely hands-off simmering time. Make a large batch and freeze portions for future use.
