Ingredients

Units Scale
  • 2 sweet onions, such as Vidalia, chopped
  • 1 shallot, diced
  • 2 tablespoons olive oil
  • 1 1/2 cups sour cream
  • 1/2 cup mayonnaise
  • 2 tablespoons dry Marsala or sherry
  • 23 sprigs thyme
  • 1 teaspoon Worcestershire sauce
  • a couple of dashes of hot sauce
  • 2 tablespoons scallions, finely chopped
  • 1/2 teaspoon kosher salt
  • 1/4 teaspoon freshly cracked black pepper, or to taste
  • 1/4 teaspoon granulated garlic
  • 1/8 teaspoon cayenne pepper, optional

Instructions

  1. Heat a large skillet over medium-low heat with olive oil.
  2. Add the onions and shallots and season with salt. Let them cook until they are translucent, about 5 minutes.
  3. Add the thyme and Marsala or sherry, continue to stir.
  4. After about 30 minutes your onions should be a pale blonde. Check to see if they need a splash of water.
  5. Continue to cook the onions until they are a deep caramel color, 50 minutes to a little over an hour.
  6. Give them a tiny splash of water to deglaze the pan, scraping up all of the brown bits.
  7. Remove from the heat and let cool. Remove the thyme sprigs.
  8. Add the sour cream, mayo, Worcestershire, hot sauce, granulated garlic, and pepper. Stir to combine.
  9. Add the cooled caramelized onions and the green onions and stir.
  10. Let refrigerate for at least 2 hours, up to overnight.
  11. Taste and adjust seasoning if desired.
  12. Serve with your favorite dippers.

Notes

  • Don’t rush the process. It takes time to caramelize onions. If they start looking dry give them a splash of water. If they look like they’re burning turn your heat down.
  • Allow your dip to refrigerate before adding additional salt. Remember that you are going to be serving this with something salty.
