Start by dicing the sweet onion into small pieces. Aim for uniformity to ensure even flavor distribution in the dip. Set the diced onions aside.
In a mixing bowl, combine the room temperature cream cheese and mayonnaise. Using a hand mixer or whisk, blend until the mixture is smooth and creamy. This will provide a rich base for your dip.
Once the cream cheese and mayonnaise are well mixed, gently fold in the diced sweet onion and the freshly grated Parmesan cheese. Use a spatula to incorporate everything without overmixing.
Sprinkle in the freshly ground black pepper. This adds a nice kick to balance the sweetness of the onions. Mix until everything is evenly distributed.
For the best flavor, cover the dip with plastic wrap and refrigerate for at least one hour. This allows the flavors to meld beautifully, resulting in a more delicious dip.
When you’re ready to serve, transfer the dip to a serving dish. Pair it with slices of baguette, your favorite crackers, or crunchy chips. Watch it disappear as everyone gathers around for a taste!
