Easy Tomato Tart Recipe (Puff Pastry)
The Oscars are this Sunday, and it’s about to get real in my house (hence these Oscar Tomato Tarts). My husband and I take the Academy Awards very seriously. It isn’t a game. What do you expect from two movie buffs that majored in film (me) and broadcast journalism (him)?
A typical scene in my house on Oscar Sunday includes several hours of research along with final predictions of the winners that evening before the red carpet sightings begin. Whoever wins the prediction game gets bragging rights for the entire year. By Sunday, we will have seen all of the nominees in the Best Picture, Director, Writing and Acting categories per usual. Told ya its serious.
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?
I find the union of an egg and puff pastry magical. The egg adds a gorgeous shine and golden browning that the pastry can’t achieve on its on. It is a must for me anytime I work with puff pastry.
Tips for Making Tomato Tart Recipe
Tip 1: For Caramelized Onions – I like to use both butter and olive oil. The oil has a higher burning point so your onions won’t burn and the butter adds additional flavor.
Tip 2: Use a round cookie cutter – They create uniform circles ensuring that you have the same size for each tart and also 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.
Tip 3: 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.
Tomato Tarts Recipe
- 2 tablespoons unsalted butter
- 1 tablespoon olive oil
- 1/2 onion sliced
- Salt and pepper to taste
- 2 sheets puff pastry thawed according to package instructions
- 1 large egg plus 1 teaspoon water beaten
- 2 large tomatoes thinly sliced
- 1/2 cup pepperjack cheese shredded
- Fresh parsley and herbs
- Melt butter and olive oil in skillet over medium heat.
- Add sliced onions to pan, season with salt and pepper and cook, continuing to stir, until tender and golden brown (this process takes a while- up to 20 minutes) then set aside.
- Preheat oven to 425 degrees.
- Using a round cookie cutter, cut circles of dough out of puff pastry and place on a parchment paper lined baking sheet.
- Brush egg wash on each pastry circle then top each with a tomato slice in the direct center.
- Next add caramelized onions on top of each tomato slice and sprinkle shredded cheese.
- Bake for 16-20 minutes or until tarts are puffy and golden brown and cheese has turned golden and melty. Top with parsley and herbs if you would like. Cool for a few minutes then serve.

This is a very tasty appetizer/snack treat. Make sure your tomato slice is not bigger than the size of your cut pastry because this prevents the pastry from baking. This happened with some of the tarts I prepared and they were soggy and unpastry-like. A little lesson learned along the way. Plus I learned something new, how to carmalize onions. Thanks Jocelyn!

Thank you for this delicious recipe. I had some left over puff pastry and wanted to use it. I made small rectangles because I only had one long strip, it made 3. I seasoned tomato with Italian spices, s&p. I didn’t have pepperjack used white cheddar, and added a little artichoke pesto on top. Cooked perfectly, I added fresh basil and some balsamic glaze…Amazing! This will definitely be a recipe I will use in the future.
Do you roll out the puff pastry? If so to what dimensions?
Jocelyn (Grandbaby Cakes) says
I didn’t roll out the dough but used my cookie cutter to cut the rounds from it
Delicious and extremely easy to make. I prepped mine ahead of time and assembled and baked right before guest arrived.
Did you refrigerate the cut tomatoes overnight? Did you have to increase baking time with cold ingredients?
Made these last night for a casual family get together. They were put together in a snap. They were a huge hit and many asked for the recipe. I sent a link to this recipe for all to enjoy. Thank you for sharing this elegant, yet easy recipe!

Just found your recipe, and they are PERFECT. It’s easy to carmelize the onions and slice the tomatoes the day before, and prep the puff pastry circles on cookie sheets–very quick and easy to assemble the next day. The recipe is also really easy to expand for a crowd…we’re like you, we don’t mess around with The Oscars, very serious business at my house. Our last bash was about 50 people!
