An onion tart is a fantastic finger food appetizer that can be served for any occasion and any guest! You start out with a large puff pastry, and you top it with some onions that have been cooked and caramelized in sugar. Once you add the caramelized onion to the puff pastry, you add some cheese and thyme, and then you bake them together! Slice it up and serve it to your guests on a platter!

I love to entertain around the holidays. Small groups, big parties…it just doesn’t feel like Christmas without a fair amount of cooking and a specialty cocktail or two. We’re not throwinga big holiday party this year, but that doesn’t mean we won’t have a few small ones.

One thing most of ourparties have in common is plenty of food (or maybetoo much if I’m being honest), plenty to drink and some good music. And unless I’m hosting a dinner party, another common factor is serving food that can be easily picked up and eaten.

That means no utensils if I can help it, appetizerplates only, and crafting a menu thatcan be enjoyedwith just a napkin in hand.

Guests aren’t trying to slice through a piece of chicken while balancing aplate on their lap witha drink in hand. Instead, they’re mingling, nibbling, chatting and, depending on the hour and cocktail consumption, dancing.

Onions also have a special place in my heart around the holidaysbecause growing up my dad always made his “famous” onion pizza on Christmas Eve. And let me tell you, it was trulyfamous with my family and friends.

French Onion Tartlets (an Easy 30 Minute Appetizer)

Every year my dad cooked upa big pot of tomato sauce filled with tons of onions andblack olives and let it simmer for hours on the stove. Then he rolled out a large pizza dough, covered it with the sauce and topped it with another dough.

It was baked until golden brown perfection and gobbled up by all of the guests that passed through our doors on Christmas Eve. And in the spirit of over-feeding, it was of course one of the many pizzas he would make that day.

While an often requested family favorite, onion pizza only came around once a year, much like a Shamrock Shake or candy corn. But it’s no wonder, as it was pretty labor intensive and time consuming.

Coming up with delectable appetizers to serve during the holiday season is one of my all-time favorite things to do when it comes to recipe developing.

I love being able to pack lots of irresistible flavor into small “packages” to enjoy with a little glass of wine as a simple snack, or to pass around to guests to whet their appetites and take the edge off a little before a bigger meal is to be served.

Crisp, hot, flaky tarts are among my favorite to prepare and serve, especially when they're brimming with creative ingredients that offer an abundance of flavor in little bite-fulls.

My French onion mushroom tart is my latest favorite to prepare, and I love to serve it on its own with a glass of wine for a date night in for my hubby and I, or pass it around to a small gathering as something to get our appetites going before enjoying dinner.

Prepared with good quality, store-bought puff pastry, layered with Gruyere cheese, caramelized onions, and sauteed mushrooms, my French onion mushroom tart recipe takes the flavor we love in French onion soup and combines it with mushrooms to create a tart with rich, earthy and incredibly savory flavors.

Part of what I appreciate about this elegant little French onion mushroom tart is that with a few steps, we have a terrific offering to share, one that is memorable and totally crave-worthy.

Caramelized French Onion Tart

Making use of good quality, store-bought puff pastry is the way to go here, so there's no need to make tart dough from scratch—a nice time saver!

The only stove-top cooking here is caramelizing the onions for the “French onion” portion of the recipe (I add a bit of sherry and beef stock to create the deep flavor), then saute the mushrooms with some garlic and a finish of fresh thyme leaves for added earthiness.

Want to simplify things for yourself, then prepare the onions and the mushrooms a day or two beforehand, so those are ready to go.
