Fragrant caramelized onions blended with mascarpone and thyme are paired with tender potatoes and encased in a flaky pastry in this free form tart that is perfect for a fall table when paired with a light salad.
The first time that I made this recipe, it was just a recycling of leftovers. But it became one of the favorites at home for summer dinner or Saturday lunch. Maybe because potatoes are a hit in my home. Also this my favorite dough, never goes wrong.
