Description

A rich and flavorful caramelized onion dip perfect for chips, veggies, or crackers—sweet, savory, and deeply satisfying.


Ingredients

Units Scale
  • 2 large yellow onions, thinly sliced
  • 2 tbsp butter (or olive oil)
  • 1 tsp sugar (optional, to aid caramelization)
  • 1 tsp salt, divided
  • 1/2 tsp black pepper
  • 1 cup sour cream
  • 1/2 cup mayonnaise (or Greek yogurt for lighter option)
  • 1 tsp Worcestershire sauce (optional)
  • 1 tsp fresh lemon juice
  • Optional garnish: chopped chives or parsley

Instructions

  1. In a large skillet, melt butter over medium-low heat. Add sliced onions, ½ tsp salt, and sugar if using.
  2. Cook onions slowly, stirring occasionally, until soft and golden brown, about 25–30 minutes. Adjust heat if edges brown too quickly.
  3. Season onions with remaining salt and black pepper, stir, and remove from heat. Let cool to room temperature.
  4. In a bowl, combine sour cream, mayonnaise, Worcestershire sauce, and lemon juice.
  5. Fold in cooled caramelized onions until well mixed.
  6. Cover and refrigerate for at least 1 hour (or up to overnight) to let flavors meld.
  7. Before serving, stir and garnish with chopped chives or parsley. Pair with chips, crackers, pita, or fresh veggies.

Notes

  • Slow cooking is key—allow onions to brown without burning for best flavor.
  • Make-ahead friendly: flavors improve after refrigerating overnight.
  • Swap mayonnaise for Greek yogurt to reduce calories and add tang.
  • For deeper flavor, deglaze pan with a splash of white wine or balsamic vinegar before cooling onions.
  • Store in an airtight container in the fridge for up to 4 days.
