Ingredients

This tomato tart on puff pastry recipe requires less than TEN ingredients! Here’s what you need:

• Fat: This tomato tartlet recipe uses a combination of butter and olive oil. The olive oil keeps the butter from burning while the butter adds a richer layer of flavor to the sauteed onion.
• Onion: Yellow or sweet onions are perfect for caramelizing. 
• Puff pastry: Use frozen puff pastry to keep it super simple.
• Egg: Adds a gorgeous shine and golden browning that the pastry can’t achieve on its own.  It is a must for me anytime I work with puff pastry.
• Tomatoes: Choose round tomatoes that are similar in size to the puff rounds you will be cutting. You can also use heirloom tomatoes in a variety of colors.
• Cheese: I love using Pepperjack cheese. It adds such a punch of flavor. You can also use other cheeses if you wish.

How to Make Tomato Tarts Appetizer

These tomato tarts are just incredibly delicious but what can you expect when you add caramelized onions, pepper jack cheese, and tomatoes to an egg wash brushed puff pastry tartlet?

1. Make the caramelized onion. Cook the sliced onion in the butter and olive oil in a large skillet. Season them with salt and pepper and cook until they’re tender and golden brown.
2. Cut circles in the puff pastry dough using a round cookie cutter and place on a parchment paper-lined baking sheet.

3. Brush each pastry circle with the egg wash.
4. Top each one with a tomato slice in the direct center.

5. Top each tomato slice with the caramelized onions and sprinkle shredded cheese.
6. Bake them in the preheated oven until the tarts are puffy and golden brown and the cheese has turned golden and melty.

7. Top the tomato puff pastry appetizer with parsley and herbs. Cool for a few minutes before serving.

How to Serve Puff Pastry Tarts

Serving up tomato puff pastry tarts works great for parties or gatherings of all sizes!

They make a delicious appetizer to serve before dinner to guests or as part of an appetizer spread for casual parties. Spinach Dip Garlic Rolls or Shrimp Nacho Potato Skins are other fun appetizers to add to the table.

For a dinner party, I love to offer them to guests as they arrive! Then serve up Chicken Francese or Chicken Parmesan for the main meal!

For family gatherings, I like to have these along with some fun, yet easy dips! Try this Elote Dip and Guacamole with some freshly cooked tortilla chips.

Expert Tips

• Use butter AND olive oil for the caramelized onions.  The oil has a higher burning point so your onions won’t burn and the butter adds additional flavor.
• Use a round cookie cutter. They create uniform circles for each tart and make the job easier.  It also helps with uniform baking.  If you don’t have a round cookie cutter, you can use the back of an empty can.
• Don’t skip the egg wash. The egg wash on the puff pastry will give a beautiful glossy and golden brown color once the tarts are baked.  This is a crucial step.
• Be sure to thaw out the puff pastry dough in advance. This will make working with it a bit easier.
• Cut the puff pastry dough slighter larger than the tomato. You want the tomato to take up most of the surface but leave a bit of the pastry visible.
