Baked Onion Dip

Baked Onion Dip

This dip is ridiculous.  It makes my “Things Worth Eating with a Spoon” list.  Seriously.

I got this recipe from my sister, Leslie, who entertains often.  This is one of her best ‘go-to-fast’ dip recipes.  I arrived late at a birthday party for my brother in-law (because I had to work) and most of the dip had been devoured.  Leslie brought the near-empty dish into the kitchen and motioned me over to her.  “There’s a little onion dip left.  You’d better get it now before anyone else sees it.”  Needing no further prompting, I grabbed the bag of tortilla chips and started shoveling.  One of the party guests wandered over to us and peered over my shoulder.  “Oh, I love that dip!” she said.  My hackles went up and I moved slightly to block her access to the dish.  “Mine!” I growled.  Then I smiled and pretended that I was just kidding.  Grudgingly (but still smiling) I stepped to the side and allowed the woman to share the rest of the dip with me.  I can be nice when I have to be.

  • 2 (8 ounce) blocks cream cheese, softened
  • 1/2 cup mayonnaise
  • 1 cup grated mozzarella cheese
  • 1 cup grated Parmesan cheese
  • 2 cups chopped onions
  • 2-3 tablespoons butter


  1. Preheat oven to 425-degrees F.
  2. Melt butter in a skillet over medium heat. Add onions. Cook until translucent and some of them are just barely beginning to turn golden, stirring as needed. Remove from heat and set aside.
  3. In a large bowl, beat the cream cheese and mayonnaise with an electric hand mixer until well blended and smooth.
  4. Add the mozzarella, Parmesan and onions; mix until well blended.
  5. Pour into an appropriate size baking dish and bake at 425 degrees for 15 minutes. I have used dishes of various sizes and shapes. This dip bakes best when it is about 3/4-inch to 1-inch deep in the dish. This may sound really picky or technical, but per my preference, I think that this gives the best results.

Note: This is a mild dip, with the flavor profile focusing on the sweetness of the onions.  If you want this dip to have a ‘kick’, then I would suggest any of the following additions—1 (4 ounce) can green chiles; as much of one minced habanero as you can stand; 1/2-1 teaspoon chipotle chile powder; minced jalapenos with or without seeds; a few dashes of your favorite hot sauce (I like Cholula® brand chipotle flavor).

Additional note: If you are serving this dip at a dinner party, I would suggest using the recipe as written. If, however, you plan to use it at something like a football game get together, then spice it up. You want the flavors to match the event.
