Ingredients

Scale
  • 4 tablespoons unsalted butter
  • 4 sweet onions, chopped
  • Kosher salt and pepper (at least 1/2 teaspoon of each, plus more to taste)
  • 1 cup sour cream or plain Greek yogurt
  • ½ cup mayonnaise
  • ½ teaspoon garlic powder
  • Fresh herbs (like parsley or chives), for topping

Instructions

  1. Caramelize the Onions:
    • Heat the butter in a large skillet or pot over medium heat. Once melted, add the chopped onions and a big pinch of salt and pepper. Cook for 5 minutes, stirring occasionally, until the onions begin to soften.
    • Reduce the heat to low (or medium-low) and cook for 30-60 minutes, stirring often, until the onions are dark brown and caramelized. If the pan gets dry, add a splash of water to prevent burning.
  2. Cool the Onions:
    • Let the caramelized onions cool slightly. You can also make them a day or two ahead and store them in the fridge. Reheat gently before using.
  3. Make the Dip:
    • In a bowl, whisk together the sour cream (or Greek yogurt), mayonnaise, garlic powder, and a pinch of salt and pepper.
    • Stir in the caramelized onions until well combined. Taste and adjust seasoning if needed.
  4. Serve:
    • Transfer the dip to a serving bowl and top with fresh herbs. Serve with chips, pretzels, crackers, or veggies.
  5. Storage:
    • Store leftovers in an airtight container in the fridge for up to 3-4 days. Let it sit at room temperature for 10-15 minutes before serving to loosen it up.

Notes

  1. Low and Slow: Caramelizing onions takes patience. Cook them low and slow to avoid burning and to develop that deep, sweet flavor.
  2. Prep Ahead: Caramelize the onions a day or two in advance to save time. Store them in the fridge until ready to use.
  3. Customize: Use sour cream for a tangy flavor or Greek yogurt for a lighter option. Add fresh herbs like chives or thyme for extra freshness.
  4. Serving: Let the dip sit at room temperature for 10-15 minutes before serving if made ahead. This helps it loosen up and become creamier.
