Preheat the oven to 400°F. Line a large baking sheet with parchment paper.
Add the ground beef to a medium skillet over medium-high heat. Cook for five to seven minutes, breaking the beef into small crumbles, until no pink remains and the meat reaches 160°F. Drain any excess grease.
Stir the barbecue sauce into the cooked beef. Cook for one minute, then remove from the heat. Allow the mixture to cool for about ten minutes.
Unfold the thawed puff pastry on a lightly floured surface or parchment paper. Gently roll it into an approximately 10×12-inch rectangle.
Spread the cooled beef mixture over one long half of the pastry, leaving about a ½-inch border around the edges.
Sprinkle the shredded cheddar evenly over the beef and press it down gently.
Fold the empty half of the puff pastry over the filling. Line up the edges and press lightly. Make one gentle pass over the pastry with a rolling pin to help secure the filling.
Cut the folded pastry crosswise into 12 evenly sized strips using a sharp knife or pizza cutter.
Hold one strip at each end and twist it two or three times. Place it on the prepared baking sheet. Repeat with the remaining strips, leaving about two inches between each twist.
Bake for 15 to 18 minutes, until the puff pastry has risen and is deep golden brown.
Let the twists cool on the baking sheet for five minutes before serving warm.
