This caramelized onion dip starts with jammy onions slow cooked until caramelized, a white wine deglaze and truffle oil finish. Make it ahead, it gets even better overnight! Grab a bag of your favorite potato chips and dig in.

Ingredients
- 1 drizzle olive oil
- 3 yellow onions small dice
- 1 teaspoon kosher salt Diamond Crystal

- 1 teaspoon kosher salt Diamond Crystal

Instructions
- Drizzle a little olive oil in a large skillet, add diced onions to and cook over low heat for 35-45 minutes stirring occasionally until onions are soft, dark and caramelized
- Once onions are caramelized, add salt, pepper, garlic and fresh thyme. Stir and allow to cook for an additional minute
- Deglaze the pan with white wine, scraping up all the brown bits from the bottom. Add sherry vinegar and beef broth then allow mixture to reduce until almost all liquid has evaporated

- Drizzle a very small amount of truffle oil over the top then garnish with chives and serve alongside potato chips
Notes
Scrape the bottom of the pan as the onions cook, stirring every 5-10 minutes
Low and slow is the name of the game with caramelized onions. Turning the heat up will result in either a burnt onion or an onion that's cooked too quickly and hasn't caramelized.
I like to chill my onions in the freezer to speed up the cooling process before adding sour cream and mayo.
A little truffle oil goes a LONG way. Do not over pour.
Dip tastes great fresh and even better after sitting for a day or two. This recipe is great for holidays and football parties.
