½cupParmesan cheesegrated
¼cupGruyere cheeseshredded

Garnish: chopped parsley
Instructions
Melt the butter in a large Dutch Oven or stockpot over medium heat.
Add the onions and cook until they start to soften, about 5 minutes. Add ½ teaspoon of salt, stir, then let them cook for about 30-60 minutes, stirring occasionally. When they start sticking to the pan, let them sit a bit to brown then stir so they don't burn. You will have to stir more often as they reach the caramelized (golden brown) stage. Note: If they are not browned sufficiently after 30 minutes try turning up the heat slightly but watch them carefully to prevent burning them.)
Add the garlic and cook for an additional minute.
Add the sherry and wine into the stockpot to deglaze it, scraping up any nicely browned bits from the bottom. Let simmer for 5 minutes.
Season the mixture with ½ teaspoon salt, pepper, thyme, and Worcestershire sauce.
Add the uncooked pasta and beef stock, and bring to a boil. Lower heat. cover and let cook for the amount of time specified on the pasta package for al dente. Stir occasionally.
Remove the stockpot from the heat. Stir in the cheeses and half and half.
Serve in individual pasta bowls and garnish with parsley, if desired.
