Preheat oven to 350 degrees F (175 degrees C).
Prepare your tart shell by pressing the Pie Crust (1) into your tart pan. Poke holes with a fork. Bake 20 minutes.
Meanwhile, heat the Olive Oil (3 tablespoon) in a pan over medium heat. Add your Red Onion (3). Cook for about 20 minutes until caramelized. Add the Brown Sugar (1 tablespoon) and mix well, cook 1-2 minutes longer.
Mix the Goat Cheese (8 ounce) in a bowl with the Ground Black Pepper (1 teaspoon). Transfer to the prepared pie shell. Spread evenly with a pastry knife.
Top with the caramelized onions and Fresh Thyme (10).
Cook 15 minutes. Let cool, cut, serve, and enjoy!
