Fresh Tomato Galette (Free-Form Summer Tart)
To make a fresh tomato galette, slice ripe tomatoes, lay them on paper towel, and salt them for 15 minutes to draw out water so the crust stays crisp. Roll out a round of flaky pastry, spread a thin layer of cheese or mustard in the middle, arrange the drained tomatoes on top, and fold the edges up over the filling. Bake at 200 °C for 35–40 minutes until the pastry is deep golden. Cool slightly before slicing so it holds together.
There is a two-week window in late summer when tomatoes are so good you almost don’t want to cook them. A galette is the exception worth making — it concentrates that ripe, jammy tomato flavour on a shatter-crisp pastry base, and it looks like you fussed when you really didn’t.
The soggy-crust problem, solved
Tomatoes are mostly water, and water is the enemy of crisp pastry. Two habits fix it every time:
- Salt and drain. Slice the tomatoes, lay them on paper towel, salt lightly, and wait 15 minutes. Blot them dry. You’ll pull out a surprising amount of liquid.
- Build a barrier. Spread a thin layer of Dijon or scatter grated cheese over the pastry before the tomatoes go on. It seals the dough so it crisps instead of steams.
Assembly
Galettes are forgiving — that’s the charm. Roll the pastry into a rough round (perfect circles are for pie tins), pile the filling in the middle, and fold the edges up in loose pleats. It’s supposed to look rustic. An egg wash gives the crust that bakery shine.
Bake hot — 200 °C — until the pastry is deep golden, not pale. Underbaked galette is doughy; give it the full 40 minutes.
Make it yours
- Cheeses: Gruyère and Dijon is classic; goat cheese and honey leans sweet-savoury; mozzarella and basil goes full caprese.
- Add-ons: caramelized onions under the tomatoes, a handful of corn, or olives and capers for a puttanesca feel.
- Herbs: thyme in the oven, basil after — fresh basil loses its lift if it bakes.
Serve warm or at room temperature with a green salad. It’s lunch, a light supper, or cut small, the best thing on a late-summer picnic blanket.
Frequently asked questions
How do I keep a tomato galette from getting soggy?
Two moves. First, salt the sliced tomatoes and let them drain on paper towel for 15 minutes, then pat them dry — this pulls out the water that would otherwise soak the pastry. Second, put a barrier layer between crust and tomatoes: a thin spread of Dijon, a scatter of grated cheese, or a spoon of ricotta seals the base so it bakes crisp.
Can I use store-bought pastry?
Absolutely — a good all-butter puff or pie pastry makes this a 15-minute assembly. Homemade galette dough is flakier and worth it if you have time, but the star here is peak-season tomatoes, so don't let the pastry stop you.
What tomatoes work best?
Firm, meaty ones — Roma, plum, or a mix of heirlooms. Very juicy slicing tomatoes work if you salt and drain them well. Cut them about 5 mm thick so they cook through without flooding the tart.
