Servings:

2 tablespoons Unsalted Butter
1 large Yellow Onion use 2 or 3 onions if smaller
⅛ cup Sherry
¼ cup Dry White Wine use a dry white wine like Sauvignon Blanc
5 sprigs Fresh Thyme
Kosher Salt & Black Pepper to taste
8 ounces Rigatoni uncooked
3 cups Beef Broth or use beef broth/stock of choice
1 teaspoon Worcestershire Sauce
¼ cup Parmesan Cheese freshly grated, more to serve
¼ cup Half and Half can use heavy cream for a richer sauce, use more or less to taste

Melt butter in a large pot or dutch oven over medium heat. Thinly slice onion and add to dutch oven. Season with a generous pinch of salt. Stir then cover and cook for 5 minutes.
Remove lid, turn heat to medium low, and cook until onions are very caramelized. Stir occasionally. This can take 20-45 minutes.
Pour in sherry and wine. Deglaze by scraping up the brown bits at the bottom of the pan. Add sprigs of fresh thyme and season to taste with salt and pepper.
Add uncooked rigatoni then pour in beef broth and Worcestershire Sauce. Bring to a boil and cook for about 15 minutes or until pasta is al dente.
Turn off heat. Discard thyme sprigs. Stir in freshly grated parmesan cheese and half and half until well combined.
Serve immediately. Serve with additional parmesan cheese.

The time it takes to caramelize onions will depend on many factors such as how thinly you slice the onions, the type of pan you're using, and the cooking temperature.
