  • Step 1

    Preheat the Traeger with the lid closed to 375°F; this will take at least 15 minutes.

    375 ˚F / 191 ˚C

  • Step 2

    Have handy two large, rimmed baking sheets. Lightly flour a work surface. Place the pastry sheets side by side overlapping slightly and roll them out until large enough to fit the bottom and up the sides of the baking sheet. Transfer the pastry to to the baking sheet, making sure the dough goes up the sides of the pan. Prick the bottom of the dough all over with a fork to keep it from puffing up. Place a piece of parchment paper on top of the dough then weigh it down by placing another baking sheet on top.

    •  All-purpose flour, for dusting

    • 2  sheets frozen puff pastry, thawed according to package instructions

    Meanwhile, line a plate with paper towel. Heat a large cast iron pan over medium-high heat. Add the bacon and cook, stirring occasionally, until brown and crispy, about 10 minutes. Using a slotted spoon, transfer the bacon to the paper-towel-lined plate leaving the fat behind in the pan.
