My Favorite Parmesan Onion Appetizer Squares

Parmesan Onion Appetizer Squares is a recipe I’ve been making since I was a new bride, way back when. Whenever I serve them, they’re always a hit with their light oniony flavor, crispy yet creamy texture, and a tiny and unexpected touch of sweetness that everyone loves!

This year (2018) I’ve decided to re-do this recipe and serve these Parmesan Onion Appetizer Squares (yet again) at our big game celebration. It seems whenever I’m planning an occasion when appetizers are served; these Parmesan Onion Appetizer Squares always make an appearance. And rightly so.

Since I originally shared this recipe for Parmesan Onion Appetizer Squares in December of 2012, it would have been remiss of me to avoid addressing a horrible mass shooting that consumed our country only weeks before Christmas. Sadly, little did we know it, this type of senseless act of gun violence and killing would soon become relatively commonplace in our world.

This is what I wrote at that time –

As we all gather this holiday season to give thanks and reflect on the year gone by, we do so with heavy hearts at the recent horrific tragedy in Newtown, Connecticut, at Sandy Hook Elementary School.

My deepest love and prayers go out the families who have lost their loved ones (so many of them little children) in such a senseless act of violence that there can never be a sufficient understanding of.

To be writing a blog post about some silly appetizers hardly seems like the thing to be doing right now, and yet, it is the return to normal activities that are so important at this time.  Life surprisingly goes on, and whatever fear you feel must be squashed before it has a chance to consume your life. I return to my kitchen to find the solace I need and the comfort that keeps me safe and in control of my little corner of the world.

The appetizer recipe I’m sharing today for Parmesan Onion Appetizer Squares is one I’ve been making for years. It’s a quick and easy recipe to throw together, and is always a hit with party guests as it’s full of flavor and tastes good hot out of the oven, or served at room temperature on a buffet table.

Here is the photo I shared back in 2012.

I love this recipe for Parmesan Onion Square Appetizers so much I’ve even shot my first “cooking-show” style video of it, which I hope to upload to my YouTube channel as soon as my new computer arrives. As luck would have it, the laptop I’m using now is far too dated and full of data that it’s not powerful enough to export a 6-minute video to my files for storage. I’m 100% positive that I’m not explaining it in proper “tech speak,” but my knowledge level in that arena is limited. In the kitchen, however, I’m far more comfortable. LOL

The ingredient list to make Parmesan Onion Square Appetizers is short and sweet. You’ll need; cocktail bread (found in the deli section of the market) any flavor you prefer, mayonnaise, fresh Parmesan cheese (grated or shredded), onion (grated), salt, pepper, dried oregano, dried basil and a touch of sugar.
Making Parmesan Onion Square Appetizers couldn’t be easier, either. Mix everything in a medium bowl, except the cocktail bread. Next spread approximately 1 tablespoon of the Parmesan mixture evenly onto the cocktail bread squares and pop them into a preheated 400-degree oven for approximately 20 minutes. They’ll come out golden, creamy, crispy and can be served hot, warm, or at room temperature so they’re perfect for any sort of party!

You can't go wrong with onion, mayos and cheese baked on top of carbs 😉 Happy holidays!
