Chicken Florentine in Puff Pastry

Instructions

• Preheat the oven to 400 degrees F (200 degrees C). Line a baking sheet with parchment paper.
• Place spinach in a microwave-safe bowl. Cover and microwave on medium power for 6 minutes. Remove cover and stir. Remove to a strainer and let cool.
• While the spinach is cooking, butterfly the chicken without cutting all the way through. Whisk egg and water together in a small bowl. Unfold pastry sheet and cut down the folds to make 3 equal pieces.
• Melt butter in a large skillet over medium heat and add chicken. Saute until no longer pink in the center and the juices run clear, 2 to 3 minutes per side. Remove to a plate.
• Squeeze spinach to remove excess water. Combine spinach with garlic, lemon juice, mayonnaise, Parmesan cheese, thyme, salt, and pepper; mix well.
• Put 1/3 of the spinach mixture in each open chicken breast and top with a 1 slice of provolone cheese. Fold the top of each chicken breast in order to sandwich the spinach and cheese in between. Place each chicken breast on a piece of puff pastry; wrap the pastry around the breast and tuck underneath to seal. Transfer to the prepared baking sheet and brush with egg wash.
• Bake in the preheated oven until pastry is golden brown, about 30 minutes.
