Ingredients
Method
Make the Dough
- In a bowl or stand mixer, cream the cold butter just until combined.
- Add lemon zest, flour, salt, and baking powder. Mix until the mixture looks sandy with visible butter bits.
- Add the egg and mix until the dough comes together in soft clumps. Add a little ice water only if it's too dry.
- Divide the dough: about 2/3 for the base and 1/3 for lattice/edges.
- Wrap both pieces tightly in plastic wrap and chill for at least 30 minutes.
Prep the Filling
- Cook vegetables to remove excess moisture (roast, sauté, or blanch).
- Drain soft cheeses if needed.
- Season with herbs, salt, pepper, and a touch of lemon juice.
Roll the Dough
- Roll each dough piece between two sheets of parchment until about 1/8 inch thick.
- Peel off the top sheet and flip the base dough into a 9.5-inch tart pan.
- Press into the corners gently without stretching. Trim extra.
Dock and Chill
- Dock the base with a fork all over.
- Chill the lined pan for 30 minutes on a baking sheet.
Fill and Finish the Top
- Spread a thin layer of cheese to protect the crust.
- Add the pre-cooked vegetables evenly.
- Use lattice strips (¾ inch wide) or crimp the edge for a clean finish.
- Chill the assembled tart again for 10 minutes to set the shape.
Bake
- Heat oven to 350°F (175°C).
- Bake on a baking sheet for 32–34 minutes, or until golden and the filling is bubbling slightly.
- Cool on a rack until warm.
Slice and Serve
- Refrigerate for 1 hour for the cleanest slices.
- Serve warm or at room temperature.
Notes
- Keep the dough cold at all times for a flaky crust. If it softens, chill it for 5–10 minutes.
- Use parchment to roll the dough to avoid sticking and stretching.
- A thin layer of cheese (ricotta, mozzarella, or fontina) on the base helps prevent soggy bottoms.
- A baking sheet under the tart protects from drips and helps brown the bottom evenly.
- This crostata freezes well; thaw in the fridge and reheat at 325°F to crisp it up.
