Three Onion Dip

  • 6

Ingredients

  • 2 tablespoons plus 1 tsp. vegetable oil
  • 2 medium onions, thinly sliced
  • 2 anchovy fillets packed in oil, drained
  • 1 teaspoon mushroom powder (optional)
  • 4 garlic cloves, finely chopped, divided
  • 4 scallions, green and white parts separated
  • Kosher salt and freshly ground black pepper
  • 1/3 cup mayonnaise
  • 1/3 cup plain whole-milk Greek yogurt
  • 1/3 cup sour cream
  • 1 tablespoon chopped fresh chives
  • 1 teaspoon Worcestershire sauce
  • Potato chips (for serving)

Preparation

Step 1

Heat 2 Tbsp. oil in a medium skillet over medium-low heat. Add onions, anchovies, mushroom powder, if using, and 1 Tbsp. garlic. Cook, stirring often, until onions are golden brown and softened, 40–45 minutes. If onions start to burn or stick, reduce heat and add water a splash at a time, scraping up browned bits. Let cool, then finely chop.

Meanwhile, heat a dry medium skillet, preferably cast iron, over medium-high heat. Toss scallion whites with remaining 1 tsp. oil; season with salt and pepper. Cook, turning occasionally, until charred, about 5 minutes. Let cool; finely chop. Thinly slice greens.

Mix onion mixture, scallion whites and greens, mayonnaise, yogurt, sour cream, chives, Worcestershire, and remaining garlic in a medium bowl; season with salt and pepper. Serve with chips.
