Caramelized Onion & Apple Slab Tart Recipe

Ingredients

• 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
