Preheat your oven to 400°F (200°C). Line a baking sheet with parchment paper and place an oven-safe wire rack on top. This setup will help create the pastry channels and ensure even baking.

Unroll one sheet of puff pastry (still on its parchment paper) over the wire rack. Gently press the pastry down into the grates of the rack using your fingers. This will create distinct channels or indentations in the dough, which will hold the filling.

Season the pork tenderloin generously on all sides with 1/2 teaspoon salt, 1/2 teaspoon black pepper, and 1/2 teaspoon garlic powder. Spread the 2 tablespoons of mayonnaise evenly over the entire surface of the seasoned pork. Carefully slice the tenderloin lengthwise into several long, thin strips, about 1/2 inch thick.

Place the prepared pork tenderloin strips into the indentations of the puff pastry, filling each channel. Sprinkle the 1 1/2 cups of shredded mozzarella cheese evenly over the pork strips.

Heat 1 tablespoon of olive oil in a large skillet over medium heat. Add the 2 grated garlic cloves and the 1 finely chopped yellow onion, sautéing until softened, about 3-4 minutes. Add the 8 ounces of sliced cremini mushrooms, 1/4 teaspoon salt, and 1/8 teaspoon black pepper. Cook until the mushrooms are tender and browned, about 5-7 minutes, stirring occasionally.

Spoon the cooked mushroom and onion mixture evenly over the cheese and pork in the puff pastry channels.

Lay the 6 slices of cooked bacon over the mushroom mixture, covering the entire surface of the filling.

Carefully place the second sheet of puff pastry on top of the filling, aligning it with the bottom sheet. Press down gently around the edges and between the channels to seal the filling. Brush the top puff pastry layer evenly with the 1 beaten large egg to achieve a golden finish.

Transfer the entire dish, still on the wire rack and baking sheet, to the preheated oven. Bake for 30 minutes, or until the puff pastry is golden brown and puffed up, and the filling is heated through.

Remove from the oven and let cool for a few minutes. The pre-formed indentations will allow for easy cutting into individual, serving-sized strips. Serve warm and enjoy the flaky pastry with its savory filling!
