Roasted Onion Dip

Meg van der Kruik
Move over store-bought onion dip, our homemade version combines a variety of deeply roasted onions, shallots, and garlic with thyme and white wine for a depth of flavor that just cannot be matched.

  • 1 large sheet pan


  • 2 pounds mixed onions; sweet yellow or red will all work, very thinly sliced
  • 2 large shallots thinly sliced
  • 4 cloves garlic unpeeled
  • 5 sprigs thyme
  • ¼ cup extra-virgin olive oil
  • 2 tablespoons water
  • ½ cup white wine
  • 1 ½ teaspoons Kosher salt
  • ½ teaspoon freshly ground black pepper
  • ¾ cup plain whole-milk Greek yogurt
  • ¾ cup sour cream
  • 2 teaspoons freshly squeezed lemon juice
  • 1/8 teaspoon smoked paprika optional
  • ½ tablespoon minced chives optional
  • 1 teaspoon Everything Bagel Seasoning optional
  • To serve: homemade or store-bought potato chips sweet potato chips, or crudité


  • Preheat the oven to 425°F.
  • Combine the onions, shallots, garlic and thyme with the olive oil and water on a large sheet pan that is at least 1-2" deep. Season with salt and pepper. Toss to coat.
  • Mound the ingredients in the center of the pan rather than spreading out; this will allow the, to steam without browning too fast.
  • Bake, stirring and tossing the onions every 10 minutes, until the onions are golden brown and starting to soften, about 30 minutes.
  • Discard the thyme sprigs and add the wine to the pan; stir and scrape up any browned bits from the bottom of the pan. Spread the onions out across the sheet pan in a thin layer.
  • Reduce the oven temperature to 400°F and return the mixture to the oven. Continue to roast for another 10-25 minutes longer, depending on how thick the onions were sliced, until they are completely caramelized and deeply golden brown. Some onions will be more deeply caramelized than others, this is ok.
  • Cool completely.
  • Transfer the onions and garlic to a cutting board. Squeeze the roasted garlic from its peel and mash into a paste with the flat side of a chef’s knife or with a fork then transfer to a medium-sized bowl.
  • Finely chop the caramelized onions and add to the bowl with the garlic.
  • Stir in the yogurt, sour cream, and lemon juice. Season with salt and lots of black pepper. Transfer to a serving bowl and sprinkle the top with paprika, chives, and Everything Bagel Seasoning, if using, just before serving.
