  • The prep consists of making the dough (or skip this whole step and just use puff pastry - Dufour's is the best you can get, in my opinion.)
  • A single pate brisee dough or 2 sheets of puff pastry
  • 2 apples, cored and thinly sliced or mandolined - you can leave the skin on or peel them, it's up to you
  • 2 large onions, peeled and thinly sliced
  • Leaves from 3 sprigs of fresh thyme
  • 1 cup grated cheddar cheese
  • 1 cup grated Parmesan, Romano or Gruyère cheeses
  • Sea salt and freshly grated black pepper to taste
  • 2 Tbsps butter or olive oil - or a mix of the two
  • A splash of stock, balsamic vinegar or water to deglaze the pan
