Heirloom Tomato Galette with Mascarpone & Sumac

If you’re looking for a dish that feels rustic, elegant, and bursting with fresh flavor, this Heirloom Tomato Galette with Mascarpone & Sumac is a perfect choice. With vibrant slices of heirloom tomatoes, creamy mascarpone cheese, and a touch of tangy sumac wrapped in flaky pastry, this galette captures the essence of seasonal cooking.

A galette is essentially a free-form tart, which means it’s wonderfully forgiving and easy to make. There’s no need for a special pan or complicated shaping. Just roll out the dough, add the filling, fold the edges, and bake until golden.

This dish works beautifully as a light lunch, brunch centerpiece, appetizer, or summer dinner side, showcasing fresh tomatoes at their peak.

• Simple rustic presentation
• Perfect use for seasonal tomatoes
• Creamy mascarpone balances the acidity of tomatoes
• Sumac adds a bright citrus-like flavor
• Easy to prepare with store-bought puff pastry

How to Make Heirloom Tomato Galette

1. Preheat the Oven

Preheat your oven to 400°F (200°C) and line a baking sheet with parchment paper.

2. Roll the Dough

Roll the puff pastry or pie dough into a 12-inch rustic circle.

Transfer it to the prepared baking sheet.

3. Add the Mascarpone

Spread the mascarpone evenly in the center of the dough, leaving about a 2-inch border around the edges.

4. Arrange the Tomatoes

Layer the tomato slices over the mascarpone, slightly overlapping them.

5. Season the Filling

Drizzle the tomatoes with olive oil and lemon juice.

Sprinkle with:

• Ground sumac
• Salt
• Freshly ground black pepper

6. Fold the Crust

Fold the edges of the dough over the filling, pleating as needed to create a rustic crust.

7. Brush with Egg Wash

Brush the exposed crust with the beaten egg to ensure a golden finish.

8. Bake

Bake for 30–35 minutes until the crust becomes golden and the tomatoes begin to caramelize.

9. Garnish and Serve

Remove from the oven and garnish with fresh basil leaves before slicing.

Tips for the Best Tomato Galette

Drain excess tomato juice

If the tomatoes are very juicy, pat them dry with paper towels to prevent a soggy crust.

Use cold pastry

Cold dough helps create the flakiest texture.

Don’t overload the filling

Keeping the layer thin helps the galette bake evenly.

Let it cool slightly

Allow the galette to rest for about 10 minutes before slicing.
