Step‑by‑Step Instructions for Heirloom Tomato Galette
Step 1: Prepare the Dough
In a mixing bowl, combine all-purpose flour and sea salt, whisking them together. Cut in very cold butter using a pastry cutter or your fingers until the mixture resembles coarse crumbs. Gradually mix in ice water, just enough to bring the dough together. Shape it into a disc, wrap it in plastic, and refrigerate for about 1 hour to firm up.
Step 2: Preheat Oven
While the dough chills, preheat your oven to 400°F (200°C). Line a baking sheet with parchment paper to prevent sticking and ensure easy cleanup. This will help create a crispy bottom for your Heirloom Tomato Galette, enhancing the overall texture and presentation.
Step 3: Roll Out Dough
Once the dough has chilled, dust a floured surface with flour. Roll the dough into a rough 12-inch circle, aiming for a thickness of about 1/4 inch. Carefully transfer it to the prepared baking sheet, ensuring it remains intact and the edges are not torn, as this will hold in the creamy filling.
Step 4: Assemble Galette
Spread a generous layer of mascarpone cheese over the rolled-out dough, leaving a 1-inch border around the edges. Artfully arrange your sliced heirloom tomatoes on top, overlapping them for an appealing design. Sprinkle sumac, salt, and freshly cracked black pepper for flavor, making sure to distribute them evenly for a balanced taste.
Step 5: Fold Edges
Gently fold the edges of the dough over the filling to create pleats, tucking them in to secure the tomatoes. This rustic method not only adds a charming look but also helps keep the filling in place. Be careful not to squish the edges too tightly, allowing the galette to expand while baking.
Step 6: Bake
Place the baking sheet in the preheated oven and bake the Heirloom Tomato Galette for 30-35 minutes. Keep an eye on it; you’ll know it’s done when the crust turns golden brown and the cheese filling begins to bubble with excitement. The aroma will fill your kitchen with a wonderful scent.
Step 7: Serve
Once baked, remove the galette from the oven and let it cool slightly for about 5-10 minutes. This resting time allows the filling to set, making it easier to slice. Serve warm or at room temperature, and enjoy this summer delight that showcases the best flavors of heirloom tomatoes.
Make Ahead Options
This Heirloom Tomato Galette is perfect for meal prep, allowing you to whip it up and enjoy later without losing any flavor! You can prepare the dough up to 24 hours in advance; just wrap it tightly in plastic wrap after chilling and keep it in the fridge. Sliced heirloom tomatoes can also be prepped up to 3 days ahead—just store them in an airtight container with a paper towel to absorb excess moisture and prevent sogginess. When you’re ready to bake, spread the mascarpone, arrange the tomatoes, and fold the edges just before popping it into the oven, ensuring a deliciously fresh and warm galette ready for your table. Enjoy your time-saving creation!

Expert Tips for Heirloom Tomato Galette
-
Butter Chilling: Ensure your cold butter is very cold to achieve a perfectly flaky crust. If it’s at room temperature, the texture will be compromised.
-
Avoid Overworking: Mix the dough just until combined. Overworking it can lead to a tough crust instead of a tender one, so treat it gently.
-
Tomato Variety: For a burst of flavor, layer a mix of heirloom, cherry, and Roma tomatoes. This will enhance both the taste and visual appeal of your Heirloom Tomato Galette.
-
Sumac Sprinkling: Use sumac sparingly; a light sprinkle adds delightful tang without overpowering the tomatoes. Remember, you can always add more if needed.
-
Serving Temperature: Serve your galette warm for the best flavor and texture. Letting it cool slightly still gives you that comforting warmth while allowing the filling to set.

Room Temperature: If you plan to serve immediately, the galette can be left at room temperature for about 2 hours, but it’s best enjoyed warm or slightly cooled for the most flavorful experience.
