Begin cooking pasta according to instructions on box.
In a large pan over medium high heat, add extra virgin olive oil.
When oil is hot, add onions. Allow them to cook with relatively little agitation for about 3 minutes. Then add garlic and salt.
Continue cooking garlic and onions, not stirring minimally, until onions begin to brown (an additional 4-5 minutes). Add more salt.
When onions are fairly brown, take 1 ladleful or ¼ cup of the water from your cooking pasta (“pasta water”) and add to cooking onions. Reduce heat. When the sauce has reduced completely, add an additional ¼ cup of pasta water.
Add cooked pasta to the onions and incorporate into the onions. Add additional pasta water as necessary if pasta is too dry.
Garnish with a little more olive oil and fresh parsley.
