Pro Tips Before You Start
Use ripe but firm tomatoes to avoid excess moisture and sogginess.
Always pat the tomato slices dry to ensure a crisp pastry base.
Let puff pastry thaw completely before unrolling to prevent cracking.
You can make your own pesto, but store-bought works great too.
For even baking, rotate the pan halfway through the cook time.
How to Make Tomato Pesto Puff Pastry Tart
Step 1: Prep your baking sheet
Preheat your oven to 425°F.
Place a sheet of parchment paper on a baking sheet and lay the puff pastry on top.
Use a fork to prick the surface all over—this keeps it from puffing too much.
Step 2: Salt and dry the tomatoes
Thinly slice the beefsteak tomatoes and lay them on a paper towel-lined plate.
Sprinkle with kosher salt and let them sit for 5 minutes. Then, gently pat dry to remove excess liquid.
Step 3: Assemble the tart
Spread pesto evenly across the puff pastry, leaving a 1-inch border around the edges.
Layer the tomato slices on top, followed by torn pieces of fresh mozzarella.
Step 4: Brush with egg wash
If using, mix 1 egg with 1 teaspoon of water and brush the puff pastry edges.
This gives the crust a glossy, golden finish once baked.
Step 5: Bake
Place the baking sheet in the oven and bake for 20 to 25 minutes, or until the pastry is puffed and golden and the cheese is melted and bubbly.
Step 6: Finish with flair
Once out of the oven, drizzle with a little more pesto and a generous swirl of balsamic glaze.
Garnish with fresh basil leaves and a light dusting of parmesan cheese.
What to Serve It With
A crisp arugula or mixed greens salad
A chilled glass of rosé or sparkling water with lemon
Fresh fruit or melon on the side for a summery meal
Sliced prosciutto or salami for a more hearty bite
Variations & Substitutions
Use heirloom or cherry tomatoes for a more colorful tart
Swap mozzarella with burrata or goat cheese
Add a sprinkle of crushed red pepper for some heat
Use a sun-dried tomato pesto for a deeper flavor twist
Try puff pastry shells for individual portions
Storage & Leftovers
Store leftovers in an airtight container in the fridge for up to 2 days.
Reheat in a toaster oven or regular oven at 350°F until warm and crispy.
Avoid microwaving—it softens the pastry.
