Ingredients

Scale

Caramelized Onions

  • 1 yellow onion, sliced
  • Olive oil, a drizzle
  • 1 tbsp butter
  • 1 pinch salt

Crispy Shallots

  • 56 large shallots, sliced
  • Olive oil, enough to coat for frying

Dip Base

  • 8 oz cream cheese
  • 3 tbsp mayonnaise
  • ¼ cup sour cream
  • ½ tsp white pepper
  • 1 tsp onion powder
  • ½ tsp garlic powder
  • Black pepper, to taste + more for topping
  • Zest of 1 lemon
  • 1 tsp agave nectar
  • 1 tsp balsamic vinegar
  • Salt, to taste
  • Chopped chives, for topping
  • Toast or kettle chips, for dipping

Instructions

  1. Slice Onions and Shallots: On a cutting board, thinly slice the yellow onion and the shallots to prepare for caramelizing and frying respectively.
  2. Caramelize Onions: Heat a pan over medium heat for about 2 minutes. Add a drizzle of olive oil followed by the sliced onions. Sauté for 5 minutes until they begin to soften. Add butter and a pinch of salt, continuing to cook for approximately 45 minutes, stirring occasionally. If the onions stick, deglaze the pan with a splash of water. Allow the caramelized onions to cool.
  3. Fry Shallots: In a separate pan, add enough olive oil to coat the shallot slices. Heat the oil to about 350°F (hot but not smoking). Fry the shallots until they turn a pale golden color. Use a spider strainer to remove the shallots and place them in a bowl to drain and crisp.
  4. Blend Dip Ingredients: In a food processor, combine the cream cheese, mayonnaise, sour cream, white pepper, garlic powder, onion powder, black pepper, lemon zest, agave nectar, balsamic vinegar, and the cooled caramelized onions. Blend everything until smooth. Taste the mixture and season with salt as needed.
  5. Assemble and Serve: Transfer the dip into a piping bag and pipe it decoratively onto a serving plate, or spread it evenly in a shallow bowl. Top with the crispy fried shallots, chopped chives, and an extra sprinkle of black pepper. Serve immediately with toasted baguette slices or kettle chips for dipping.

Notes

  • Slow caramelizing of onions develops deep sweetness and flavor; be patient for best results.
  • Maintain the frying oil temperature around 350°F to achieve crispy shallots without burning.
  • If you do not have a food processor, you can mix the ingredients with a hand blender or vigorously whisk for a slightly chunkier texture.
  • Store leftovers in an airtight container in the refrigerator for up to 3 days.
  • For a dairy-free version, substitute cream cheese, sour cream, and mayo with plant-based alternatives.
