National Potato Chip Day – Caramelized Onion Dip

March 14, 2023 is National Potato Chip Day. Have you noticed how many different flavors of potato chips there are in the grocery? Every flavor from traditional sea salt to black truffle and olive oil, even Nashville Hot Chicken Flavor! I like to think of myself as somewhat of a potato chip connoisseur if only due to the number of potato chips I’ve eaten in my life. Potato chips are my favorite food group. I absolutely love them.

You just can’t beat a really good dip to serve with potato chips. Here’s my best ever recipe for Caramelized Onion Dip…it always disappears quickly when I serve it to guests. This chip and dip combo is a delightful pairing with champagne too – it was one of Marilyn Monroe’s favorite snacks.

Caramelized Onion Dip

Course Appetizer
Servings 2 cups


  • 4 tablespoons butter, divided
  • 1 tablespoon olive oil
  • 2 cups yellow onion, finely chopped
  • 1 large shallot, finely chopped
  • 1/2 cup red onion, finely chopped
  • 3 tablespoons champagne or white wine
  • 1 teaspoon fresh thyme
  • 1/2 teaspoon garlic powder
  • 1 1/2 cup sour cream
  • 3/4 cup mayonnaise
  • 1 bunch scallions, chopped
  • salt and pepper to taste
  • zest 1 lemon
  • 1 teaspoon capers
  • chopped chives for garnish


  • Melt 2 tablespoons butter in a saute pan. Add olive oil. Stir and heat over medium-high heat. Add onions, shallots and a pinch of salt.
  • Cook without stirring until onions start to soften and color, about 2 or 3 minutes.
  • Caramelize onions by stirring them and reduce heat to medium. Add 2 tablespoons butter and continue cooking onions until golden brown, stirring occasionally to prevent sticking or burning.
  • Once onions have reached their desired color, add champagne or white wine. Scrape bottom of pan to pick up any caramelized bits and fold them back into onion mixture. Remove from heat and stir in thyme and garlic powder.
  • Place the sour cream, mayonnaise, one half of scallions, salt, pepper, lemon zest and capers in a mixing bowl. Add caramelized onion mixture to the sour cream mixture and stir to combine all ingredients.
  • Garnish the dip with chopped scallions and chives. Serve with potato chips or crudites.
