  • Total Time: 45 minutes
  • Yield: 4 servings 1x

Ingredients

Scale

Chicken Filling

  • 2 cups cooked chicken, shredded or diced
  • 6 slices crispy bacon, chopped
  • 1 tablespoon ranch dressing mix
  • 1 teaspoon garlic powder
  • 1 teaspoon onion powder
  • 1 cup shredded mozzarella cheese
  • 1/2 cup grated parmesan cheese

Dough and Topping

  • 1 sheet puff pastry or 1 portion pizza dough (about 12 x 8 inches)
  • 2 tablespoons melted butter or olive oil (for brushing)

Optional Variations and Add-ons

  • Chopped jalapeños or 1/4 teaspoon cayenne pepper (for spicy kick)
  • Substitute roasted vegetables for chicken (vegetarian version)
  • Low-carb tortilla or cloud bread (low-carb option)
  • Alternative cheeses such as sharp cheddar, pepper jack, or gouda
  • Fresh herbs like rosemary or thyme

Instructions

  1. Prepare the Chicken Filling: Shred or dice cooked chicken breast into bite-sized pieces. In a large bowl, combine the chicken, chopped crispy bacon, ranch dressing mix, garlic powder, and onion powder. Add shredded mozzarella and grated parmesan cheeses, tossing gently to create a rich and creamy filling.
  2. Roll Out the Dough: On a clean surface, lay out your puff pastry or pizza dough and roll into a rectangle approximately 12 by 8 inches. Ensure the dough is thin enough to wrap around the filling without tearing but thick enough to hold the ingredients securely.
  3. Assemble the Bake: Evenly spread the chicken filling over one half of the dough, leaving a small border around the edges to seal. Fold the other half of the dough over the filling carefully. Press the edges together by pinching or pressing with a fork to seal and prevent leakage during baking.
  4. Brush and Score the Dough: Brush the top surface of the dough with melted butter or olive oil to achieve a golden, crispy crust. Lightly score the top with a sharp knife to allow steam to escape and keep the crust flaky.
  5. Bake to Perfection: Place the assembled bake on a parchment-lined baking sheet. Bake in a preheated oven at 400°F (200°C) for 20 to 25 minutes, or until the crust turns golden brown and the cheese inside is bubbling and melted.

Notes

  • Use warm chicken when mixing to help the cheese melt evenly in the filling.
  • Do not overfill the dough to avoid bursting or leakage during baking.
  • Freeze the assembled but unbaked chicken bake for 15 minutes before baking for easier slicing and cleaner edges.
  • For extra shine and color, brush the dough with a beaten egg instead of butter before baking.
  • Let the bake rest for 5 minutes after baking before slicing to prevent the filling from spilling out.
