Caramelized Onions

  • 3 medium sized white onions, halved and thinly sliced
  • 1 tablespoon olive oil
  • 1/2 teaspoon kosher salt
  • 2 teaspoons balsamic vinegar
  • 3 tablespoons dry white wine

Cream Cheese Onion Dip

  • 6 ounces cream cheese, softened
  • 1 cup sour cream
  • 3 green onions chopped, white and green parts
  • 1 1/2 tablespoons tamari or soy sauce
  • 1/2 tablespoon balsamic vinegar
  • 1/2 teaspoon ground black pepper
  • 1/4 teaspoon garlic powder
  • 3/4 teaspoon kosher salt
  • 1/3 cup toasted California walnuts, finely chopped


  • Add olive oil to a large skillet. Add onions, stir, and bring to medium heat. Do not stir again for 5 minutes. 
  • Add salt, stir, and turn down heat to medium-low. Cook for about 45 minutes, stirring occasionally, until golden brown and caramelized. They should soft and sweet. Stir in balsamic vinegar and white wine. Bring heat back to medium-high to evaporate liquids. Remove from heat and set aside to cool for 10 minutes. 
  • To make dip, add all dip ingredients to a large bowl. Then add 3/4 of the caramelized onions. Stir to fully incorporate. 
  • To top, add remaining caramelized onions to the top. Serve with tortilla chips or potato chips.
