“Mashed beans hold the filling up off the pastry.”
Puff pastry does most of the work here, which leaves one real question: how to put a wet filling on it without ruining the base. The answer is beans.
Half of them are mashed into the ricotta, which thickens it enough to hold the tomatoes up. The rest stay whole for texture, and everything that goes on top is blotted first.
🍅 The promise: Filling reaches 160°F (71°C), pastry underside is crisp, and tomatoes do not flood the tart.


During “Spread a firm ricotta base,” use this checkpoint for Butter Bean Tomato Puff Pastry Tart: whisk ricotta, egg, Parmesan, and half the salt; spread inside the border.
Use “Bake to a safe set” to reach the final cue—filling reaches 160°F (71°C), pastry underside is crisp, and tomatoes do not flood the tart—and stop there.
Heat the oven to 400°F (205°C) and lay the cold thawed sheet (245 g) of puff pastry on a parchment-lined rimmed sheet pan. Run a knife ½ inch (1 cm) in from the edge all round, cutting halfway down, then prick the inner rectangle all over.

Beat 1 cup (250 g) ricotta with 1 large egg (50 g), ½ cup (50 g) grated Parmesan, 1 tsp (1 g) dried thyme, and half the 1 tsp (6 g) kosher salt until smooth and pale, roughly the thickness of soft frosting.

Tip the rinsed can (425 g) of butter beans onto a towel and pat them completely dry, then mash half of them into the ricotta with a fork. Leave the rest whole so the finished tart keeps some soft, starchy bite.

Spread the filling inside the scored border in a layer about ½ inch (1 cm) deep. Press 1½ cups (225 g) halved, blotted cherry tomatoes cut side up across the top, season with the remaining salt, and tuck the whole beans between them.

Bake 28 to 30 minutes, until the border has puffed into crisp golden layers and the filling no longer wobbles when the pan is nudged. A thermometer in the center of the custard should register 160°F (71°C).

Brush the hot border with 1 tbsp (15 ml) olive oil for shine, then tear ¼ cup (15 g) basil leaves over the tomatoes. Slide the tart onto a board and cut 8 squares with a serrated knife.

The base lifts crisp and dry underneath, the tomatoes have slumped and caramelized at their edges, and each square slices cleanly. At “Spread a firm ricotta base,” whisk ricotta, egg, Parmesan, and half the salt; spread inside the border; adjust ingredients only after comparing the batch with the cue that filling reaches 160°F (71°C), pastry underside is crisp, and tomatoes do not flood the tart.
Dry the beans and the cut tomatoes on a towel before either touches the ricotta; nothing else protects the pastry as well.
