Place a long piece of parchment paper in front of you and fold it in half like a book.
Unfold and pour about 1/4 to 1/2 cup of BBQ sauce onto the parchment paper. Place the chicken breasts on top and coat them in the sauce.
Fold the parchment paper over, and starting at one end of the parchment, fold the edges of the paper over several times continuing to make creases all around the chicken until it’s completely enclosed and no air can escape.
Place the parchment packet on a baking sheet and bake for 30 minutes.
