Roasted Onion Mayonnaise

Caramelized onions accent the mayonnaise in this delicious sandwich spread.


3 cups (24 servings)


2 sweet onions, peeled, and halved
2 cups mayonnaise
salt and pepper to taste


Preheat oven to 400°F (204°C). Line a baking sheet with aluminum foil and lightly grease.

Place the halved onions onto the baking sheet, and roast in the preheated oven until they have turned deep golden brown, and have softened in the center, about 30 minutes. Remove from the oven and allow to cool to room temperature.

Place the onions into a food processor or blender, add the mayonnaise, and puree until smooth. Season to taste with salt and pepper.
