My father had a Chardonnay tasting and asked me to bring an hors d’oeuvres. I had no time to shop and had to dig around my kitchen for ingredients. I found puff pastry, which I always have in the freezer, brie, onions and apples, so this is what I came up with and it worked.
Caramelized Onion, Apple & Brie Tartlets
2 Tbs olive oil
2 onions, thinly sliced
1½ Tbs fresh thyme, minced
salt & pepper, to taste
1 sheet frozen puff pastry, thawed
1 large Granny Smith apple, peeled, diced
12 oz Brie cheese, rind removed, cut into ¼” cubes
Heat oil in a heavy large skillet over medium heat. Add onions and sauté until deep golden brown, about 30 minutes. Mix in thyme, season to taste with salt & pepper. Cool. Can be prepared one day ahead, covered and refrigerated.
Roll out cold pastry on lightly floured board. Cut pastry with a round small cutter, fit into a mini muffin tin.
Preheat oven to 350 degrees.
Spoon 1-½ tsp onion mixture on top of each pastry square. Top with apples. Bake until pastry is golden brown, about 20 minutes. Top each square with one piece of cheese and bake just until cheese melts, about 3 minutes longer.
Transfer to platter and serve warm.
