Try the making the dip with sweet onions, it's super delicious. Bake until the crust is well browned. It'll help caramelize everything. You can mix the dip ingredients several days ahead of time, and then bake it off when needed. We've even kept it unbaked in the fridge for a couple weeks and it was still great. 



  • 8 ounces Cream Cheese , at room temperature (1 package)
  • 1 cup Mayonnaise (preferably Best Foods/Hellmans brand)
  • 1 cup  freshly grated Parmesan cheese (not the powdered cheese stuff in the green containers)
  • 1 medium Onion , diced (try sweet onion, it'll taste better!)
  • 2 teaspoons Black Pepper , freshly cracked if possible
  • 1/2 teaspoon Garlic Powder


  1. Preheat the oven to 350°F (175°C).
  2. In a bowl, mix together the cream cheese, mayonnaise, parmesan, onion, black pepper and garlic powder until everything is thoroughly combined.

  3. Pour the mixture into a 6-inch (15-cm) baking dish or any oven-safe dish. Bake for 50 minutes to 1 hour, or until everything is melted together and the top crust is brown and almost burnt-looking. The darker brown the crust becomes, the better the flavors are.
  4. Serve with your favorite crusty bread, crackers, slices of tomatoes, or crunchy vegetables such as radishes, jicama, carrots, and celery.
