Sweet Onion and Parmesan Dip

It’s football season… and hockey season… and World Series time. The holidays are right around the corner, then New Year’s Eve, and before we know it… the Super Bowl. This all means that it’s a very good time to stock up on fabulous, easy appetizers. Not that there is ever a bad time. Appetizers and desserts are my favorite food groups, after all. When it comes to appetizers, dips trump all in my world. If a dip is especially cheesy, it gets bonus points. Yesterday, my father-in-law came over to watch some football with my Chief Culinary Consultant; I was bouncing around the kitchen and wanted to give them something to snack on since it would be a few hours before dinner would be ready. I didn’t want to run to the store, and I wanted something warm, easy and not time-consuming. That’s not too much to ask, right?!
I remembered coming across this recipe recently and it seemed to fit the bill perfectly. Five ingredients, all that I had in the house, and literally five minutes to throw together and get into the oven. Dip success!
A sweet onion is diced up and mixed together with cream cheese, mayonnaise, Parmesan cheese and black pepper. That’s it! The mixture is baked together until the top is nice and golden brown, and then try to hold people back. This totally unassuming dip is hopelessly addicting. You can’t quite it. I dare you. Since I didn’t want to go to the store, I served it with some tortilla chips and pretzel crisps that I already had in the pantry. This would also be great with baguette slices or crackers.
I love stashing away quick and easy appetizer recipes that can be thrown together when you have last-minute guests or need to balance a complex holiday menu with a really simple appetizer. If you’re serving a crowd, you may want to scale the recipe up, as four adults completely demolished this dip in short order!

I made a similar recipe: 1 onion, 1 cup shredded parmesan, 1 cup mayo, black pepper, bake, fill bread, cover with Mozarella and melt (brown). People LOVED it. I will try this as well. I’m sure it’s delicious.
There is never any left! Good stuff.
This is delicious and one of our favorite appetizers ever! I could eat this with a spoon. I also experienced the layer of grease on top after baking but I am not bothered by it. Letโs face it, itโs not a healthy dish with all the mayonnaise but sometimes you just need something yummy! Thank you for the excellent recipe.
Made this for New Year’s Eve and it was amazing! Everyone loved it, and it was SO simple.
I have been wanting to try this recipe for a little while now, and I finally made it tonight! Very tasty – and my husband loved it, too!
This is delicious and super easy. I used low fat cream cheese and slightly less pepper with excellent results. Thank you!
