Equipment

1 Cutting Board
1 Chef's knife
1 Large Skillet For caramelizing onions
2 Mixing Bowls One for sautéed onions, one for combining dip ingredients
1 Rubber Spatula or Wooden Spoon For stirring and mixing

Ingredients

Main

1 medium yellow onion
2 tablespoons olive oil
1 teaspoon kosher salt or more to taste
½ cup minced shallots
½ cup diced red onions
½ teaspoon granulated garlic
1 tablespoon minced dried onion
¾ cup mayonnaise
2 cups sour cream
¼ teaspoon freshly ground black pepper
⅛ teaspoon cayenne pepper
⅓ cup thinly sliced green onions or more to taste
¼ cup thinly sliced fresh chives or more to taste

Instructions

Cut both ends off the yellow onion and cut evenly into 2 halves. Remove and discard skin. Place onion halves on a cutting board with cut-sides down. Make vertical slices against the grain, then turn and slice across the cuts to chop. Chop again if you'd like smaller pieces. You should have about 2 cups chopped onion.
Heat olive oil in a large skillet over high heat. Transfer onion and salt into the hot oil. Cook until onions are deep brown in color, 7 to 8 minutes. Add shallots and red onions; stir and saute until they start to soften and sweeten, 3 to 4 minutes. Turn off the heat and stir in garlic and dried onion. Set aside to cool completely, about 20 minutes.
Combine mayonnaise, sour cream, pepper, cayenne, and cooled onion mixture; mix until thoroughly combined. Cover and chill in the refrigerator for 4 to 12 hours, or overnight.
Remove dip from the refrigerator and stir in green onions and chives. Taste and adjust seasoning. Transfer dip into a serving bowl and garnish with more green onions and chives to serve. Dotdash Meredith Food Studios

Notes

Achieving a deep, rich caramelization on the yellow onions is crucial; don't rush this step, as it forms the flavor foundation. The addition of dried onion provides an essential "umami" depth reminiscent of classic French onion dip. Ensure the cooked onion mixture cools completely before combining with mayonnaise and sour cream to prevent the dairy from breaking or becoming oily. The extended chilling period is vital for the flavors to meld and deepen, transforming the dip from good to exceptional. Taste and adjust seasoning at the end, considering the saltiness of the chips or accompaniments. For an extra touch, lightly toast some breadcrumbs with a pinch of everything bagel seasoning and sprinkle on top as a garnish.
