It’s Friendsgiving, and you’re invited! Entertaining friends is easy with these delicious little treats.

These bite sized onion tarts can be served straight out of the onion or at room temperature. Either way, they’re always memorable.

The thick, flaky puff pastry is topped with caramelized shallot (a type of onion) that’s sweetened with a hint of brown sugar, fresh goat cheese and a crack of pepper. It’s an easy appetizer everyone will love!

I use shallots because they have such an incredible flavor and you can slice to the perfect size. They caramelize quickly, too!

Onion Tart

Ingredients and Substitutions

  • Puff Pastry – My favorite shortcut! If you want to make it from scratch, you can make your own puff pastry with this easy recipe.
  • Butter – Use salted butter if you have it. If you only have unsalted, you’ll want to add a little salt along with the pepper later.
  • Shallots – If you can’t find shallots, you can use a regular white or yellow onion. Learn how to cut an onion here!
  • Brown Sugar – Dark or light brown sugar is great here, and don’t forget to pack it down when you measure.
  • Goat Cheese – Crumbled for the topping of these onion tarts.
  • Fresh Cracked Pepper

Tips

  • Bring frozen puff pastry come to room temperature before rolling for best results.
  • It may seem like a lot of shallots but as you may recall from my post on how to caramelize onions, they reduce.
  • To add a little shine to these tarts, use an Egg Wash before baking.
  • They also jam up which makes them so incredible! As the puff pastry rises around them, it creates a little delicious pool.
  • The easiest way to top with goat cheese is to allow it to soften while caramelizing the onions, then using a fork and dropping onto the pastry.

Frequently Asked Questions

What’s the difference between a shallot a yellow onion?

Shallots are a little more sweet and delicate. While they have a some of the same sharp flavor you know from onions, traditional yellow onions are more intense! However, they can often be used interchangeably.

Do shallots get sweeter when cooked?

Yes! Shallots and onions both get sweeter when they are cooked, especially if they are caramelized over low and slow heat.
