A flaky, buttery puff pastry tart topped with melted Gruyere cheese and roasted heirloom tomatoes, perfect for summer gatherings and easy to prepare in about 40 minutes.
Keep puff pastry cold until baking for best puff. Blind bake the crust to avoid soggy bottom. Pat tomatoes dry to maintain crispness. Tent with foil if edges brown too fast. Let tart rest before slicing for cleaner cuts.
