Top Tip

When working with a puff pastry sheet, it’s best that it’s very cold. Once the dough gets warm, it becomes more difficult to cut and may start to spread prematurely.

If you start with the dough, make sure to place the dough rounds back in the freezer wrapped in plastic wrap until you are ready to assemble the tarts.

Variations

You can switch up the cheeses or the seasonings in this tart recipe. The tarts would be delicious with parmesan cheese or fresh mozzarella. Also try fresh basil or rosemary.

The next time I make these I’m planning to try cherry tomatoes. We love the Sugar Bombs. See if you can find them at your grocery store. They have a black label so they are easy to spot.

A drizzle of balsamic glaze would be wonderful, too.

FAQs

Can you freeze tomato tarts?

Though it is better to eat these tarts fresh, you absolutely can freeze them, too. Place them in an airtight container for up to 3 months.

What can I serve with tomato tarts?

You could serve these before dinner with another appetizer like this roast beef crostini. This easy recipe pairs well with any of these Italian dinner ideas.

Could I use a different kind of cheese in these tomato tarts?

You could! Fresh mozzarella cheese, burrata cheese, or gruyere cheese would all be heavenly. Shredded mozzarella would work, too. You could also try goat cheese.

Notes

Notes:
Keep the dough very cold. Once it becomes warm, it becomes more difficult to cut and may start to spread prematurely. Take the dough out of the freezer just as you are ready to assemble the tarts, or place the dough rounds back in the freezer until the ingredients are ready.
Do not leave the onions to cook. If they burn, the sweetness will be lost and you’ll have to start over.
Check the tarts at 16 minutes as oven temperature can vary.
